BarraMan's Mangusta 21 barraboat in Townsville, AUS

OK, fire the starting gun - I am off!

My plywood arrived today so I guess this is as good a day as any to declare the start of my build.

Here's my build start pic!

Image

Details of my ply is as follows: Bruynzeel Hechthout Marine Plywood is a Gaboon/okoume throughout plywood panel with selected gaboon/okoume cores and is manufactured in compliance with the British Marine Plywood Standard BS1088-1:2003. The plywood carries Lloyds Register type approval and also carries a 10 year structural guarantee against defects.

It is superb looking plywood.

For those who don't remember my ruminations on this, the plan is to build the Mangusta 20 hull, but up-scaled by 10% and built with a side console and fore and aft casting decks.

Gonna be an interesting 2013!

Those are going to be some cool modifications to that plan. Like a bass boat, right? It ought to be fast, I think I remember you saying that you were going to power it with a 250. 8)
I'll be following.

Sounds awesome BarraMan,

Good to see another FNQ bloke building boats from here! I'm in Innisfail.

Where'd you get your ply, resin and glass? Did you get Au STD sized ply or the full sized 2440 x 1220mm that these boat plan's nesting diagrams prefer? Have you noticed the difference in what we pay over here compared to what they seem to pay in the U.S.?

A mate of mine has land up at Tinaroo and was toying with the idea of having me attempt a Mangusta for him, so I'll be watching your thread!

Good luck, can't wait to see it come together.

Cameron.

G'day Cameron
Where'd you get your ply, resin and glass?
I bought the ply from Denman Marine in Tasmania. They appear to be the only source of this high quality marine ply.
See here: http://www.denmanmarine.com.au/ Andrew Denman was very helpful.

I haven't started shopping for resin and glass as yet (about to do so!) but these things are readily available.

West System (resins) have a good distributor network, including Cairns and Townsville: http://www.westsystem.com.au/
Boatcraft Pacific have pretty much anything you may require in resin, glass, paint etc: http://boatcraft.com.au/Shop/
Did you get Au STD sized ply or the full sized 2440 x 1220mm that these boat plan's nesting diagrams prefer? Have you noticed the difference in what we pay over here compared to what they seem to pay in the U.S.?
The ply I bought is 2500 x 1220 mm. I did look at buying it in from Bateau at one stage but then found Denmans. Not much difference in the price of the ply by the time you land it here.

Yes, I am aware of the premium we seem to pay for living in Oz! I buy a lot of stuff from the US these days and can often land it here for 50% of what I would pay locally. Often there is a middleman (distributor) who is to blame, not the local retailer.
A mate of mine has land up at Tinaroo and was toying with the idea of having me attempt a Mangusta for him, so I'll be watching your thread!
I have had the plans for the Mangusta for a couple of years. Interestingly, only a couple have ever been built, as far as I am able to determine. I was going to build it as a ski/wakeboard boat, but realised that it would only be used for that activity a couple of times a year as our boys no longer live at home. As my alias indicates, I am a Barramundi fishing tragic and I also wanted a boat that could use to explore some more remote fishing locations. I figure 3 x boats is a bit silly, although I have a mate who has three, so I thought I could utilise the Mangusta hull to kill a couple of birds with the one stone - mostly as a BIG barra boat, with occasional duties towing skiers/wakeboards.
Good luck, can't wait to see it come together.
Cameron
Its gonna be interesting!

Thanks for the links, that's sweet! My wife will be stoked at the prices too. I'm currently doing a V12 sailing dinghy from the small boats section, but after this one I'm getting a little more ambitious. I have plans for the HM19, but I've recently toyed with the idea of the FL26. Guess I'm working up to my retirement cruiser in years to come. Tw28.. or bigger..

Looks like we can have a bateau builders meet in Townsville. Haha... Might be a bit lame with just the 2 of us.

Anyway thanks again for the web links, now get cutting, I'm so keen to see a Mangusta come along, I think you're right with the lack of them completed so far, such a shame too as it's an awesome looking boat.

Good luck once more.

Cameron.

Yeah, 250 hp 4-stroke is the plan. The standard hull is rated to a max. 250 hp. The 10% upscale should take care of the extra weight of the 4-stroke, but I will beef up the transom, stringers and some of the glassing to be sure it will handle the power. The decking will also be structural and there will be lots of foam-filled sealed chambers - not to be used for racing or the like so should be all OK.

Have to say mate, that is a crazy price for plywood, compliant with X standard or otherwise. 8O Good luck with the build Bubba. :wink: I'm quite surprised you didn't opt for the Phantom 18 considering the area you will be fishing.

Someone said, "Get cutting"! So I did.

Built my strongback.
Image

This thing will just fit into my garage with the boat on it. Fortunately the garage has doors at both ends (a full width door on one end) and the strongback is on castors so I can move it around to get more working room as needed.

Started cutting out molds. The little Makita circular saw is just the thing for the job. Cuts nice curves too, especially if the blade depth just matches the ply thickness.
Image

Transom and clamping boards cut out and dowelled, ready for laminating.
Image

Molds cut out and ready to go - only a couple more to do.

Progressing steadily!

All molds are cut out. bottom and side panels marked and ready to cut. Given that I have increased the dimensions by 10%, I spend a bit of time just sitting an thinking about things and checking calculations and measurements - have picked up a couple of mistakes before it was too late.

Have had my first adventure with epoxy!

I decided to use West System epoxy because it appears to be well regarded for this sort of work and is readily available in this part of the world - but not in my town, apparently! I visited the local supplier who is listed as a agent only to find they had only 2 L on hand - "Its on order"! Isn't that always the way! I will source it in a larger quantity from down south.

Was interested to see that they were selling wood flour for 4 x what I paid for a bulk order direct from the manufacturer.

I figured that 2L was enough to make a start on laminating the transom - my first serious deal with epoxy!

I had gone with "slow" hardener, as temps are around 30oC here at the moment. All was proceeding nicely until a moment of panic came when I noticed that the roller I had used to coat the ply with straight epoxy had started to smoke, when I was busy spreading epoxy/woodflour glue. Fortunately the epoxy and glue on the transom was still wet (I guess being spread out over a large area helps), and the lamination appears to have been successful. I did another layer in the evening when things had cooled down a bit and had no more smoking rollers.

Image

I think I will need to experiment with "extra slow" hardener before attempting any big glassing jobs.

I am happy with my progress and feeling pretty confident about this build - at the moment anyway.

If you are wondering about all the bottled water - we live in a cyclone (= hurricane) zone (!), so we keep a good supply of bottled water in our "cyclone kit".

Makes good weights for laminating!

I think you will like that better, for my main build I imported the Silvertip from Bateau, but I use a lot of west also with hardeners from fast to extra slow,I used the extra slow the most and worked very good for me, we have almost the some working temperatures, don't know about the humidity :doh:

Peter, humidity here ranges from about 70 - 90% at the moment.

Just curious, given the temp, for what sort of applications did you use fast hardener?

Gday Barraman, i live in the Ville and would love to have a look at the Mangusta as it comes along.

Its one hull that I have allways loved. I opted to rebuild a Haines Hunter 1600 so using all of the tips and tricks from this site and Epoxy resin.

Made for a strong floor and Transom!

cheers
Good luck with the heat

Hi Barraman,

When I first found this site I also looked at the Mangusta 21, but decided on the OB19, i have recently start my build and will follow your build closely, it will be interesting to see another Mangusta coming together.

Good luck with your build.

As far as I have been able to determine there have only been two Mangusta 20s built. Don't know why that is - its a great looking hull IMO.

This build is only Mangusta up to the sheer (hope I have my terminologies correct) - it will have flat decks front and back and be fitted out like a bass boat.

I was attracted to the 18o dead-rise at the transom and the size of the boat (then "supersized" it by 10%) because I want to explore some of the more remote Barra fishing locations available to me in north Qld.

So far at least, I am really happy with my decision to do this - its gonna be really interesting!

Oh yeah - and I have always wanted to build a boat so this will be one thing crossed off my bucket-list!

I have worked for 40 years mainly with my head, but I have always been pretty good with my hands so this project is really enjoyable and satisfying for me.

So Peter, are you suggesting there are more, or in fact only one?

The "fmiles" Mangusta build is well documented, and I thought I saw a hint of another - by "badwater"' maybe".

The Mangusta 20 appears to have been conceived in 2002 - that's all I can find.

I seem to be a "do-er" rather than a "document-er" ! :lol:

Coming along steadily.

Image

I had some issues getting it level, straight and square, even with the lazer level I bought especially for the job. Cummulative errors seem to be the problem so I pulled it all apart, upped the precision and started again. Everything is now within +/- 1mm.

Its a BIG sucker! Had to roll it out of the garage to get it all in a photo. I have the stringers cut and laminated, and the side and bottom panels cut out. Hope to get them spliced during the week for a big "stitch-up" this weekend.

I am really enjoying this.

Of course we'd all like to look over your shoulder as you work, promise not to get in the way. :) One reason to consider posting photos as you go along: if somebody here sees something going wrong or some way that it could be done easier or better, you might benefit. You may find a time that you want to refer back to a stage of your work, and good photo documentation might be just the thing. (that's two reasons- math never was my favorite subject). :P

BarraMan,
She's starting to take the shape of a boat! Nice progress.
I used WestSystem for most of my build on both my builds actually, (shipping epoxy from bateau was big $$) the 410 was great for the fillets, mix with a little wood flour, it's also great for a fairing compound mixed straight with thier epoxy, when I ran out of woodflour I used 403 for glueing.

Keep up the nice progress.

Big day on the job for me today - bottom panels spliced!

Image

So what have I learned so far?

Its a lot easier to write, "I am going to scale the plans up by 10% that it is to execute that intention"!

Not that scaling up itself is difficult - but it takes what already a fairly big boat and makes it a really big boat! Interesting when you are working solo.

Its hard to get the scale of these things in a photo, but that garage is 6 M (19.7 ft) deep!

My pile of wood is well down in size - it should start to look like a boat soon!

I am away for work all of next week but hope to get the side panels spliced next weekend.

Stitch-up should follow soon after!

An update seems in order.

I have been working away, slowly but steadily - I try to do a bit every day.

External keel and chines triple-taped!

Image
Image

I am very happy with my progress and my work to date. I think I have epoxy glue and taping sussed, although its pretty interesting sitting on top of an 18o dead-rise hull, taping the keel! :lol:

I think I have managed to achieved a nice bow profile.

Image

Dealing with this "monster" in our double garage is a bit of a challenge. It just fits in on the diagonal - with 1/2 inch to spare - so I swing it around to give me a bit of room to work on it. You can see that our driveway has a fair slope - I have had it right out on the driveway for sanding a couple of times but its a tough job for Mrs Barraman and I to get it back up into the garage. I may rig up a winch to help with that.

Image
Image

Taping the transom today, then getting up the courage to attack the "big one" - sheathing the exterior in 12 oz cloth.

Like most, I spend about 3 hrs thinking for every hour building, and so far its going well.

I think you have to build one of these boats to really appreciate the advantages of the building method. You can read all you like about how strong these boats are - but when you build you one you can see first hand how it works.

Way cool!

Tried something new - for me. Up till today I have always rolled some straight epoxy on the surface to be glassed prior to putting the glass cloth down and wetting it out. For the 2nd layer of biax cloth on the transom I tried wetting out through the cloth. Worked out well!

Gives me confidence to attack the next BIG step - glassing the bottom and sides.

Thanks!

I think the biggest challenge for someone with good basic woodworking skills building one of these boats is coming to grips with epoxy and glassing. Its been a steep learning curve for me but has worked out pretty well - no major disasters so far.

I am a little apprehensive about glassing the bottom and sides because of the scale of the task and the fact that I am working basically solo, with my wife mixing for me.

Cheers

Lee, you will do great. I wish I had had an extra hand to mix epoxy when I was glassing mine. That transom looks great! You got the hang of this fiberglass and epoxy. Check Larry's GF18, he had all his resin and hardner premeasured and laid out in different color cups. Smart way to prevent a major screw up!

Hi Lee, that looks good, mate. :D
The bottom and sides are not as daunting as it seems. :D I fitted all the cloth lengths dry and numbered them. I checked the overlaps as per schedule. Layed out your first cloth, mixed a pot and it was game on. :D
I used a roller to spread the epoxy, and the a squeegee to work it through - especially on the vertical pieces. On the horizontal pieces I poured the epoxy and worked it through with the squeegee.
I found peelply helped a lot with the chemical cleaning of a layup. Once the blush has migrated through the peelply and it comes off with it, the surface is ready for the next layup(You can feel it when you run your hand over - does not feel waxy in the least).
Very neat build, well done. Oh, agreed - the extra hand to help mix is a big help.

Lee : looking at that job, no worries about the rest of the hull!

To state the obviouse, be a bit carefull with the peel, take a bit of time to get it straight! (treated nice, its magic stuff) I created one hell of a rod for my own back with a really bad application of the peel ply, styill filling and sanding my way out of that one :lol:

Having s couple of big strong sons home for the weekend seemed like a good opportunity to pull the boat out of the garage and give it a good all-over sanding prior to glassing the bottom and sides.! :lol: :lol: :lol:

Image

I have a bit of hook in the keel at the rear of the boat that I am looking to eliminate before covering the bottom. Probably more than should be just faired out so I have put in some glass cloth "filler".

I am new to peel ply Matte, so I will have a bit of a play with it before committing to the real thing. All part of climbing the learning curve! :D

I have been beavering away glassing the bottom and sides. I am glad I was a bit anxious about this cause it made me spend a lot of time thinking it through.

Has been going really well - I am very happy with the boat.

Takes me 4 - 5 hrs to wet out a 6.5-7.0M run of 12oz biax cloth - depending on how much help I get from Mrs Barraman with mixing expoxy.

We have a new show on TV here called "Slideshow" where they act out skits on a stage that is tilted 22.5 degrees. Apparently that is the limit that people can just manage to stand on without sliding away.

Sitting the bottom of an 18 degree dead-rise hull is a bit of a challenge too, but seemed like the easiest way to get the job done.

Just watch those glass shavings(sandings) on your legs and feet. I wear a long sleeve overall with gloves and shoes with elastics to pinch the sleeve ends else I do not sleep at night. The vac also helps a lot - I see you have one attached.
Have you planned the strakes yet?
Good work, mate - keep it up.

A tip from Chief Brody:
Wow, no long sleeves or Tyvek suit? I'm amazed you're not cursing at night after the demo work..... .....When you start grinding I would highly recommend a little more skin protection and lots of talc powder...helps keep the glass dust out of your pores.

Justin, I had never touched glass or epoxy before starting this boat. They say to build something small to start, and that is very good advice, which I ignored completely! :lol: :lol: :lol:

By the time you have taped the seams and maybe the transom you will start to gain some confidence with glassing - and I think it is really all about confidence.

Read all you can on this forum and spend lots of time thinking about what you are going to do and how you are going to do it.

Don't take on more than you can readily handle. I only ever do one 6.5 - 7.0M wetting out run in a day. Means a bit more preparation (ie sanding etc) between layers but it keeps it to what I can reasonably handle by myself. If you have help you may take on more.

I have used West System epoxy throughout my build. I think it may be more expensive than some other brands but west System has worked very well for me and I am really pleased with the results.

My advice is whatever epoxy you use, be sure to use slow hardener - because of ambient temps in Darwin. You will need to be particularly careful wetting out large areas in the summer heat. I am trying to get all of my exterior glassing done with before things start to warm up here.

Good luck with your build - I look forward to following your progress.

Cheers

Lee

Cheers Lee.

I am also using the West System stuff, you wouldn't believe it, but i rang around the whole country and the cheapest I could get it was my local dealer. That is a first for Darwin. I am using the 206 slow hardener and already had to put one pot down. Definitely have to mix it and then spread if out.

I am looking at buying my marine ply for the hull, so far the best stuff I have seen is at bunnings, but I am not sure about it as it has 3 ply and the middle ply is much larger than the outer two. I have posted s question to Jacques to see if that is ok.

I will try and get the hull cut and stitched this weekend and then things will slow down a bit as my wife and I are expecting our first bub the weekend after, anytime now I guess.

Good luck with the rest of your build, I will keep an eye on it.

Cheers

I used Bruynzeel Hechthout BS1088 Gaboon Marine Plywood, which I purchased from Denman Marine in Tasmania. Its beautiful ply wood and also very light - but it is expensive. Fortunately, for me, cost is not a primary consideration in for my build. :lol: :lol:

That's ok mate, I am using the West System aswell so I have the pumps. I find that anymore than 15 pumps goes off too quick if you don't get it spread out.

Are you buying the 4L resin tubs, or the 20L....are the pump sizes the same?

I'll work on about that too.

West does make a 209 Extra Slow Hardner. That might be just the ticket for those extra big layups in the tropical heat. It is a 3:1 ratio hardner.

I rigged a winch so that I could pull the BEAST back up the driveway into the garage - so it was an opportunity to roll it out and give it wash before laminating the last layer of glass. :D

I am going to apply peel-ply over the last layer of glass. Have had a bit of a test run with it but it will be a bit of a challenge applying peel-ply to 6.5 - 7.0 M runs of glass.

I have been keeping track of the weights of glass cloth and epoxy going onto the boat. I am running at about 52% epoxy to 48% glass, so I am pretty happy with that - for a newbie! :lol: :lol: :lol:

I am no expert on this stuff, but since you asked, here is "peel ply according to Barraman"!

As I understand it, you can use peel ply with all layers of lamination as it leaves a surface that has any amine blush removed by the peel ply and is ready for the next layer without the need for sanding. I opted to only use peel ply on the last layer of fibreglass lamination.

The next thing that I did was get Mrs Barraman involved. Boy was that a smart idea! :lol: She is a quick leaner and very picky - so air bubbles and wrinkles are her new enemy. I was able to focus on wetting-out the glass while she worked on removing wrinkles from the peel-ply. She now likes to tell people that she is a boat-builders apprentice! :lol:

The first run we did (having no previous experience!), we applied the peel ply after I had finished wetting out the entire 6+M of glass. It was a bit difficult to handle such a long length of material and quite difficult to get all the wrinkles out - but we got most of them and result was excellent. Mrs Barraman then suggested that we apply it in shorter lengths next time and for this mornings run, that's what we did - 1.5M lengths at a time.

We are having a September heat wave here at the moment, so I was also concerned about the epoxy going off before we got back to putting on the peel ply, so we started at 06:30 this morning and put the peel ply on after I had wetted out about 1.7M ahead of it.

Here's the glass laid out on a "wet" hull.
Image

The pic I forgot to take that should be in here is the hull with about 1.5M of glass wetted out!

This pic shows peel ply applied to the first section of wetted out glass. You can see the small area of wetted-out glass ahead of the peel ply and dry glass in front of that.
Image

Jobs done! Peel ply applied to the whole glassing run - in sections. We used a dry foam roller to smooth the peel ply onto the wetted out glass.
Image

Once the epoxy has gone off you just peel off the peel ply - it doesn't stick to the epoxy! Magic! :lol:

If you don't use peel ply, it looks like this when dry - and you can feel the weave in the fibreglass cloth. All the indentations will need to be filled with fairing compound.
Image

With peel ply it looks like this - much, much smoother to run your hand over and minimal fairing required.
Image

I'll add a couple more pics when I peel off the peel ply from this mornings effort.

Hope this helps!

Cheers

Lee

Absolutely lovely work Barraman, you are right – done properly, peel ply is awesome!

I faired with the Bote-Cote family of products, although I found :D a kiwi company ‘Pure Science Ltd’ that may be importing QuickFair into QLD shortly. I also had some luck using a 9” drywall sander to knock the peaks down. That said my friend – looking at what we have seen from your build already, I don’t think you will have too many dramas.

Hi Lee,

I ended up getting the same RO sander as you from bunnings, doing the job just fine!

The dust collecter is rubbish though, absolutely rubbish!!

You said you hooked yours up to a vaccum cleaner and you work almost dust free, this sounds awesome. I went in and checked out some vaccums for the job and the guy was trying to sell me a $300 model.

Was hoping for cheaper, what are you using, the guy told me if I get a really cheap one it will blow up with all the really fine dust.

Would be interested to know what you have found out.

Monsoonal conditions here so struggling to get anything done :(

Yep, me too. You can get some fancy ones but I bought an el cheapo wet and dry vac from A Man's Toy Shop. It has a removable/cleanable/replaceable filter - which I clean regularly.

Make sure you use a quality dust filter mask on yourself Justin, not one of the cheap throw away kind! That dust is very fine and will stuff your lungs. I always wear mine when sanding and emptying the vacuum and cleaning the filter.

Mine's a 3M type - I can get you the spec if you need it.

Nah Mate, been through lots - and this one is only a baby! :lol:

Looks like its gonna go south of us anyway. Crossing the coast is likely to coincide with 4M king tides, so inundation is a bit of an issue for those in low lying areas.

We sit high and dry, even though we are on the bank of the river (high side).

On the one hand it may mess with opening day of the Barra season (Saturday) - but on the other hand the big rain will only help the Barra fishery.

Was going to glass my strakes today - but that is on hold for now.

Thanks for thinking of us.

Hi Lee,

Batten down the hatches, they upgraded Dylan to a Category 2....good luck!! :wink:

We had that cyclone in Darwin just before Christmas, cyclone Allisia, it was a category 1. Didn't get Darwin directly but it sure dropped a bit of rain and got the floodplains filling up. Then we got a really strong tropical low and it basically hasn't stopped raining for the last 3 weeks, and looks to continue well into the next week.

It is great for the barra, the floodplains are full and starting to pump runoff into the big rivers. The culverts have started to fire around Darwin too, guys pulling 90cm fish from the side of the road.

It is the time of year that every barra fishermen starts getting itchy...you want it to keep raining to flll the plains more, but you also want to get into the runoff. Patience!!

Check out this vid of the Daly River, check out the colour change in some of the runoffs :D
http://vimeo.com/user20571737/review/85 ... 90bb365c94

On the downside everything is growing mould, you know how it is....including my boat which I haven't managed to glass yet. I had a sneak peak under the covers and the wood is green :(

I am about to start fairing - lucky me!

Had a brainwave today to turn the boat around so that it is transom first into the garage. So I rolled it out and down the driveway onto the road, turned it around and then winched it back up the driveway.

Imagine my surprise to discover that it DOES NOT FIT into the garage that way! :lol:

It did give an opportunity to take a pic from a somewhat different perspective while it was on our sloping driveway.

That tropical low out your way looks a bit confused hey, the track map shows it looking like a cork screw.

How's the barra season looking your way, looks great here, we've had heaps of rain and the floodplains are full. I'm going for a look later this week, hopefully there is some runoff action in the South Alligator river :)

What are you using to fair up your hull?

Good luck with it all.

Raining at Airlie Beach - not raining here. Suggests that it is south of us, but there is some suggestion that it may turn back our way. I think its gonna be a bit of a fizzer.

Barra season here is lousy, Justin! March 9 and I have yet to boat a legal Barra.

I'm using West System 401 Microlight fairing filler with West System epoxy and slow hardener. I am trying to avoid using very slow hardener cause I don't like it.

I started fairing the bottom and sides of my boat.

Well! It didn't take long for me to get thoroughly bored with that did it?

My original plan was to flip the boat a couple of times - glass the bottom and sides, flip the boat, glass the interior and fit the stringers and bulkheads so it is all fixed and secure then flip it back upside down to fair and paint the bottom and sides. However, I was somewhat intimidated by the prospect of flipping a BIG boat so I had resigned myself to a single flip - then I saw the "Cracker Larry" method of single-handed boat flipping and thought, "I can do that"!

So here is the Barraman method of flipping a 22' boat almost single-handed! I was able to hire a portable gantry and endless chain, and I borrowed an engine crane from a mate.

I rolled the boat out onto the driveway and erected the gantry over the transom.

Image
Image

Then I setup the engine crane over the bow.

Image

Disconnected the boat from its strongback trolley and cranked it up in the air.

Image

Then rolled it over!

Image
Image
Image

A quick modification to the strongback.........

Image

.......and then put the boat back on it right-way up! :D :D :D

Image

TOO EASY! :lol: :lol: :lol:

Great job Lee, looks awesome mate! :D

You can never get too many ideas, I like the idea of fitting the stringers and some of the frames in then flipping it back to fair the bottom. I'll consider my options too.

The profile of the boat looks awesome. A couple of big casting decks, look out barra.

I did the freshwater fly comp last weekend in a billabong out of Darwin and got 7 barra, 4 saratoga and about 25 tarpon. It was the first time I had thrown a fly so I was happy with that!!

I sent you my email address for those strake details, not sure if you received it?

Keep up the good work.

Cheers

Not sure what you're getting at Peter - those wheels are rated way above the weight of the boat and strongback!

But yes, I will have to upgrade them before towing the boat behind my vehicle. :lol: :lol: :lol: I plan to put it on its trailer after I have faired and painted the bottom and sides.

What a system BarraMan. She is a beauty indeed.

Seems it is flipping time for a few. I really wanted to do everything by myself but the flip I could not due to logistics but gathering 10-12 peeps is proving to be more of a hassle :lol: Great you can do solo.

Then you don't have a problem so ignore my last comment, if you were going to finish her on that cradle there was a good chance those casters were way to light, they may be rated fine but paper is patient, don't ask me how I know.

PS don't know if the saying paper is patient exist or means the same as in Dutch, I literally translated it :oops:

Hah! I am like a Sports Illustrated photographer with an air brush! :lol:

I pre-primed the area for filleting/taping, and when done with that gave the whole thing a sand and pre-primed the remainder ready for glassing - makes most of the messy stuff disappear! :D

I must have embarrassed the West System epoxy cause it is blushing! Never seen this before although I did everything the same as for the exterior. Will give it a good clean up prior to glassing.

Aaaaaaaaah! Disaster struck yesterday! :(

I started to glass the inside of the boat yesterday after much thinking and planning. Attempted to do it exactly the same as I did the external glassing (wet on wet) which was superb.

Oh Dear! The glass would not lie down flat in the bow area and I was having great difficulty wetting out the glass to my satisfaction.

End result? I ripped it all out 8O before the epoxy went off, tossed it into the middle of the back yard - and went and had a good lie down! :lol:

Write off A$100 of 12 oz biax cloth and epoxy!

Now thinking through Plan B.

HI, Yip, that's neat work 8) . Is the plan the same for port side and then a strip down the middle?
If you don't catch the wet edge then the cleaning of a large area can be a bit crappy - I find it more difficult inside the boat than out. Outside I rinsed off and let dry after sanding. Inside its the shopvac and cloth.
You are also having winter now? How long after glassing do you still have a tacky feel - wet edge?
Do you have 2 layers of biax wide cloth on the bottom - inside? Check the lamination schedule carefully. Those overlaps on the chines and bow adds to the thickness of the layup and structural strength. Make sure you get those as per schedule.
Looks good.
Cheers

Yeah mate, 2 x layers of glass on the interior bottom and sides. Plan is to fill in the boottom space with either one piece overlapped 150 mm, or I might do it in two pieces overlapped along the keel. Its a real challenge working on the interior bottom of a medium/deep V boat - not much room to move on the side and I keep sliding to the middle!

Overlaps etc are per the specs or close to it - its overbuilt anyway with 3 x layers of cloth on the exterior rather than two. It will end up with a minimum of 14 layers of 12 oz biax along the keel and and chines - either continuous or 150-200 mm overlaps.

Hey BM, just a thought. Since it's a Deep V hull, couldn't you tip it sideways and work the glass from the outside of the boat? Roll it over 45 degs on some tires covered with old blankets. That way you have your feet on level ground and gravity working on your side instead of climbing in and out of the boat. Certainly going to be a lot less exhausting. An extension handle for the roller should get you enough reach to do the whole side. Once done, flip it the other way. I'd love to be able to do that on my TW28 but sadly it's not an option.

Sorta like what this guy did.

http://1.bp.blogspot.com/-Mbozx888zBw/T ... e+hull.jpg

My 2 cents worth.

Hi Knotty,
Walkers Run tried with his CS25 - did not pan out so well since the hull is not rigid enough yet. I looked at that and it would have made a big difference, but the possibility of a crack made me man up and slide the hull(on me backside 8O - no pics luckily) whilst glassing. Good idea, though. Maybe Barra's 21's sides are more rigid with the extra biax in.

I have seen that done before. Would be pretty confident the hull would handle it but can't see how I could do it in the work space I have available. In a workshop maybe.

I will proceed as I have - I know I can get it done that way.

I can't handle any more than one of these big glassing sessions in a day so I have to sand and clean between. I did this for the exterior and it worked out fine. I have put a bung hole in the bottom of the transom so my routine is to sand, hose out, allow to dry and then wipe down with acetone before the next glassing session.
You are also having winter now?
Yes, daily temps of 16 - 26oC
How long after glassing do you still have a tacky feel - wet edge?
I am using West System's "Slow" hardener - I get about 4 hrs of working time for "wet-on-wet" glassing.

Looks great Lee, very polished as always :)

Better to take it slow, with a bit more work in between layups and get it right. You'll end up spending the same time if you stuff things up a bit and have to fill holes, etc.

I just had 5 days off to try and get some progress on the boat, I wanted to get the rub rail, spray chine and strakes on and then start fairing....but now I have shelved it all until I hear back from the gurus. I'll get the yard and pool cleaned up instead :lol:

Antonie, that post caused me to have an "Oh crap!" moment and scramble for the lamination schedule! :lol:

It says, "2 layers internal and external overlapping the chine by 150mm"!

"Phew"!

OK so I probably didn't need to run the glass right up the sides, particularly for the second internal layer, but as I have built the hull 110% of design size I figure a bit of extra strength will not go astray.

By my calculations it only adds about 16 lbs to the weight of the hull.

G'day Lee, enjoyed our lunch, and the boat is looking good!

After your account of barramundi in Deluge Creek, the child bride and I worked the tides, coaxing our 44' keeler over the bar just before high tide before kicking back and enjoying the drop dead gorgeous anchorage. No barra for this neophyte though. We loved Zoe Bay, Agnes Island, Cape Richards and Haycock Island. Then after three months of cruising north, we spun the wheel and started heading south. We'll pass our home port of Noosa in October on the way to deep southern Tasmania, which we'll circumnavigate in Feb-March next year if the Great Southern Ocean and the roaring 40 permit.

Cheers,

Michael.

Being a curious kinda person, I started to wonder what the displacement of my 10% up-sized Mangusta hull would be. So I connected a water meter to a hose and filled the boat with water to the design water line.

1850 litres = 1850 kg = 4070 lbs

Interesting!

Yep! No worries - it didn't even creak a bit!

I was gonna fill it right up to get the total volume, but decided 9 tonnes might be pushing my luck! :lol:

So I estimated that based on volume increase per 50 mm up the transom.

Did you change your filler mix for the bigger space wedge towards the front of the hull to avoid it from slumping out?
Once they are taped in and you tap on them you can hear by the harmonics that is rock solid and part of the whole structure. :D

The MG20 plans do not notch the stringers.

I have been using an epoxy/wood flour mix for my fillets. As long as I get the mix right (just before it looks dry) I have had no problems with fillet droop! :lol:

Hi Justin, it says in your lamination schedule if you have to glass the stringers and frames. I suspect it might be in the building notes as well.

Hi Antonie,

My plans say glass the stringers and frames for sure, but not all the way to the top. I guess this is just for piece of mind.

I know Jacques only puts what is required at a minimum.

G'day Justin

I glassed the stringers before I put them in. I don't think you need to do so, and its not in the lamination schedule for the boat, but........

I had an earlier e-conversation with Jacques where I queried whether I should increase the thickness of my stringers (ie laminate 2 x 12mm rather than 2 x 9 mm) because I have up-scaled the plans by 10%. He assured me that was not necessary - so I opted to glass them with 12 oz biax for a bit of added strength.

Now that they are in I don't think it was necessary. Jacques will say, "I told you so"! :lol:

Glass as per the lamination schedule and give the bare stringers the Cracker Larry double coat of epoxy and everything will be fine.

Cheers

Lee

Nice work Lee. I know you'll enjoy installing each remaining bulkhead as much as you have this one. We're about to slip our Noosa lines and sail our way southwards for the next five months or so. We're aiming to circumnavigate Tasmania next Feb-March, when the Great Southern Ocean at least offers an even money chance of winds less than 30+ knots continuous. :) On route our boat will be displayed as an example of cold moulded construction at the Australian Wooden Boat Festival in Hobart in early Feb. I'm aiming to exhibit a completed Jacques Mertens ST21 at the next AWBF in Feb 2017. Are you still thinking of exhibiting your big barra boat then too? Best, Michael.

Looks like a perfect fit!

I'm very curious, do you cut your bulkheads larger than required and then reduce the size to fit? Or do you cut it right in one go? I assume they are just slightly smaller than the cross-section so that epoxy putty can fill in the gaps?

Re: BarraMan's Mangusta 21 barraboat in Townsville, AUS

Posted: Tue Nov 11, 2014 11:21 pm
by BarraMan

Selever

Yes, pretty straight forward for a master craftsman like me! :lol:

Alternatively, here's what I did......

I cut the bulkheads as per the plans, set them up on the strongback and then positioned the bottom and side panels and stitched them as per the plans. Once everything looked as it should, I placed a few stitches to keep the bottom and side panels in position as far as clearance from the bulkheads goes.

Then I glued, taped and cloth'd (?) the exterior hull, flipped the hull and removed the bulkheads.

Once I had glued, taped and cloth'd (?) the internal hull, I started to refit the bulkheads - leaving the hull pretty much in the natural shape that it had taken up. I have not given any attention to pulling in the sides or bottom to the bulkheads. They were pretty close anyway. Maximum gap in that 2nd bulkhead above is 1/2" about halfway up the side panel - same on both sides.

I positioned some ceramic tile spacers to give about 1/8" clearance of the bulkheads from the bottom and side panels, and used a flapper sanding disc on a 5" angle grinder to trim the bulkhead as required to accommodate the glass tape and cloth layers - with no hard spots. Then I filleted and taped the bulkheads to the bottom and side panels. I just filled the gaps with carbosil/woodflour/epoxy filler while making my fillets.

Once the fillets are double taped, as per the plans, nobody is any the wiser as to how good the fit was - although it was pretty close - within tolerances I believe.

I think you get a bit of a bow in the side panels as they find their "relaxed" position after being bent around the lines of the boat. I figure it is better to leave them that way if not too big rather than start pulling the panels in and losing the nice smooth curve lines of the hull.

Cheers

Lee

Most of the bulkhead in the foreground will be cut away to make the cockpit.

Once all six bulkheads are in, I just have to do a bit of finishing around the transom and then it will be time to flip it over again and fair and paint the exterior hull.

I hope to be ready for that by Xmas when the boys will be home to give me a hand.

Yeah Antonie, its a work in progress! The bulkhead in the pic below is in the middle of the cockpit (the middle gets cut out) and has fuel tanks either side of it over the keel.

My concern is that if I drain it to the bilge, then petrol fumes will have a direct connection to the bilge pumps and livewell pumps. Seems like a potential 'kaaaaabooom' issue!

So I plan to vent the fuel tank compartments elsewhere and make provision for being able to siphon and aerate them if they happen to take any water.

All the compartments under the sole other than the fuel tanks compartments will be foam filled and sealed, and the cockpit will be self-draining through scuppers. Front and rear casting decks will have reasonably water-tight hatches and the compartments under them will all be drained.

Should work?

Cheers

Lee

As for retirement? Well, I never really planned that but I guess it catches up with everyone eventually. Unfortunately my university has been restructured to the point that I barely recognise the place I came to many years ago - so I figure it can go on without me.

There is a boat to be built, and another 1+ metre Barramundi out there with my name on it just waiting to be caught, and places my ever-patient, ever-loving wife would like to visit, and enough consulting opportunities available in my area of expertise to fund my fun and keep old-timers disease at bay for a good few years.

My younger son (the fisherman!) says that now I am a full-time boat builder I should be able to put in 12-14 hr days working on the BIG boat!

So I put in a solid day today working on the motorwell. Didn't make the Xmas Day flip, but I am close.

Some boats have twin outboards - mine has twin cans of beetroot! :lol:

Beetroot cans wrapped in plastic tape make a nice radius for the corners of the motorwell. Worked out really well - will post another pic when I have trimmed them up. :D

Well!

There is good news - and there is bad news.

First the good news - the boat is flipped!

The bad news is that the camera stopped video recording before the flip so there is no video.

Stinking hot here - it nearly killed me.

Mrs Barraman took some stills as I was getting ready to flip it. I'll take a pic of it upside down on the strongback again - later when it cools off a bit.

Castors - what he said. My castors were fine for an empty shell, but once I got all the bulkheads and stringers in they failed first move. Had to jack up the whole project and add 5" ones, I think they were rated for at least 1000 pounds each.

Yes, it's a big sucker! Interestingly, now that it's upside down and I can get a grip on it, I can still lift the nose. Most of the weight is in the rear end - as you would expect.

I would be interested to know what it weighs. I am about to order a trailer for it. When I get that I will run it over the scales, then put the hull onto it and check its weight.

As for the wheels/castors - don't tell Peter he was right or he will get a swelled head! I had one rear wheel "blow out" (buckle) yesterday and will have to replace that. I still hope to get away with what is on it. Don't plan to move it about much during fairing and painting - an then it can go onto the trailer to be finished.

Got a couple of days work around the house to keep the cook onside - then I will be back into it. All fired up for fairing - iI want to get this sucker finished!

HI Barra, well done on the flip. You had it so easy on the first one, something had to happen on the second - hence the buckled wheel :D :D . The fairing will go quick - all looks strong and sound.

No break in the weather for me, just through all my Christmas obligations and have a week of holidays left and now the monsoon has landed. Check out the radar for Darwin.

You are lucky you have a garage so you can work all year round, mine is bring build under a lean-to, so very much weather dependent.

Looking forward to seeing yours come together though, make sure you post lots of tips on fairing cause I am using the same system as you :lol:

For this project I broke down and bought a full face mask. The eyes take a beating too, and for me it is impossible to find a combination of respirator and goggles that isn't uncomfortable, hard to see through, and a pain to put on and take off. The full mask is worth every penny. The cartridges in your old mask are interchangeable with the full face model so you can buy just the mask. I have a chronic cough that was the result of too many years wearing no mask at all :roll: .
The boat is looking great.

I have been using a nose/mouth mask but will look at a full-face mask for fairing. I have my RO sanders hooked up to a dust collection system that works very well, but fairing boards will put dust into the environment - to be avoided.

Here's the mask.
http://www.amazon.com/3M-Respirator-690 ... 8QNTAZR2DD
They are pretty expensive, $89.95 plus shipping. The one listed in this link comes without cartridges, but they are commonly available and the mask is compatible with whatever 3M cartridges you already have. I just transferred the ones from my 1/2 face model. I'm not a medical expert but I don't think you need a very sophisticated cartridge unless you plan on spraying LPU.

Mine never steams up and field of view is considerably better than you get in any model of protective eyewear that I've ever used. I find it much less uncomfortable than either goggles or a 1/2-face respirator, not to mention both at the same time. They come in three sizes and that's a sort of difficult thing to judge as I couldn't find anyplace to try one on. So I just went with medium which fits fine. I have a hat size of 7 1/4 but I'm not certain how relevant that is. You can exchange them if you don't get a good fit.

An accessory I bought which is a very good idea is a bag of these shields:
http://www.amazon.com/3M-Faceshield-Cov ... GKB76T8Q7C

This is another bunch of money but they are sacrificial. Whatever you're doing that requires a mask will very likely be messy, and if you scratch the lens on your mask or get paint or epoxy on it, it will be hard to see through. So you use one of these for awhile and replace it (very easy) and the lens on your mask stays untouched.

I resisted this for a long time because of the expense, but when you consider it compared to the entire project, it is less than the paint. As I said before, I've had my health impacted by stupid, macho carelessness about such things when I was younger, healthy, and thought I was too much of a manly man to need these appurtenances. But once you damage your health, even to the modest level I did, that manliness has a chink in it that cannot be repaired.

Yep I used those also, but honestly if you are on a tight budget I would wait with the tabs, drive the boat and see if you really need them, I know I ain't using mine a lot, boat comes in plane very nice and fast as it is, not sure but I think that goes for all Jacques designs, don't forget you can do a lot of trimming with your OB also.

I would add, get the new helm either baystar or seastar depending on your HP, it has the positionable compression fittings. The dealers might have old stock as what happened to me and it can make life easier with the positionable fittings.

Also don't buy the kit, but the components separately and get the seastar hoses, much easier to layout. The baystar are hard and hold their shape like crazy, real pain to route them.

I also second wait on the tabs.

Started on this fairing caper in ernest today with a bit of preparatory work.

Put a woodflour/epoxy putty edge on the bottom of the transom.

First made a "dam" with some plastic board.

Image

Then ran a bead of putty along the junction.

Image

Will sand it off to form a sharp edge tomorrow, then do the same with the last 4M of the chines on both sides.

Ordered the trailer for the BIG Boat this afternoon - ouch!

Hi Barra, yip, I did it the same way. I sharpened the chines as well up to the 'plane-line'. The same with the strakes....not sure how practical that was, but besides fairing, shaping these took me the longest. Mostly due to over sanding and then re-moulding - duh. I suppose the proof is in the pudding. I like the trailer - I hope you insisted on pensioners discount :D . Looks good and strong - is that a break-neck trailer? Makes life a lot easier with bigger boats if the loading bed can tilt back.

35-40 years ago, back before "float on" then "drive on" trailers became available and before carpeted wooden bunks were used, pretty-much all boat trailers would tilt. IIRC: if you didn't tilt the trailer while launching/recovering your boat, it would void the trailer warranty.

I didn't know that you could still buy a boat trailer that tilts :o , but there are still certain ramps that almost require a tilt trailer. I've been thinking about converting mine.

I remember the MagicTilt brand, and as I was posting about the "float on" style, I was thinking that Float-On might be a brand, too. I googled them to learn that both brands are still in production. I also found a link to another forum where someone asked the difference in a "drive on" style vs a "float on" style. Part of one of the answers was very amusing 8O

Oddly enough I have seen a Float-On brand trailer that said right on the side "Do not Submerge"

Justin, you just had to ask, didn't you! I have been trying to keep a low profile in here!

Started out well - exterior hull sanded and chines, strakes and the bottom/transom junction (whatever that is called?) sharpened.

I invented the Barraman method of chine sharpening - works great and easy to do. Will post some pics when I have a chance.

And then life got in the way! Had an unexpected road trip to Brisbane and back - 1400 km (870 miles) each way. Got back yesterday, just ahead of a major weather event that looks like it will close the road with flooding.

Back into it today!

I am having a late Xmas, with lots of presents arriving over the next few days. They tried to deliver my fuel tanks yesterday before we got back, so I have to go pick them up this morning. My jacking plate should arrive from the US tomorrow and trim tabs and other goodies are also due to turn up soon. Will order the Teleflex Seastar Pro hydraulic steering today.

Trailer is being built as I type this.

Wet season is looking good - here's hoping for a good Barra season! I may not get out on opening day this year for the first time in 14 years cause I hit a rock with the Minn Kota a few weeks ago and bent the drive shaft - its away being repaired.

Cheers

I was looking through Cracker Larry's current build the other night and realised that the Barraman method of making sharp chines is essentially the same as the Cracker method - so I won't bother taking out a patent! :lol:

I used "plastic" board , called corflute here, to create a dam. Rolled a thin layer of epoxy with fast hardener on the strake and the board and then "stuck" the board to the strake.

Image
Image

When that had gone off, I ran a bead of epoxy/woodflour along the edge to be sharpened.

Image

Once that had set I pulled off the board.

Image

After 12 hrs to harden up, I will trim with my trusty little plane.

My jacking plate arrived from Bob's Machine Shop last week and my Bennett's Sport Trim Tabs arrived today. Teleflex Seastar Pro steering is on its way.

Bit of an update for those interested in my build.

Fairing is progressing well and I can actually see the progress and imagine an end to it. Not that fairing this boat is particularly hard given that I used peel-ply on all my external glassing - it just that it is BIG, and fairing the bottom is really uncomfortable sitting on a sloping surface with a sharp strake running down the middle of it.

I have become a bit anal and am essentially "blue printing" the bottom - aspiring to the high standard set by CL. It is straight (at least for the last 3 metres), fair and true.

My new random orbital sander is my best friend. The old one threw in the towel!

Hope to finish fairing in the next week. Will post pics when I have something interesting to show.

Fairing is the doldrums of boat building. You work for days and weeks, and the picture never changes. Not much gratification. But then one day you're finally done. When you first think you're done, walk away and rest for a couple days, then come back and do it one more time :D

Glad to know you made it through the fairing and posting again. :lol: I was wondering if it had defeated you or not. I am pretty sure that if the fairing was easier there would be more boats built or at least less abandoned projects. Now I am waiting to see how the girl looks with her makeup on :D

Mate, this project was always going to get finished - I have too much invested in it to quit! :D

Fairing the bottom of a BIG 18o deadrise hull is a challenge for an old bloke like me! Its quite physical and not just a little uncomfortable sitting on the upturned bottom with strakes that I have "sharpened" very nicely.

I also had a slight hook near the transom that I had to sort out.

All done now - finished fairing the bottom today. The transom was finished some time ago. The sides won't take long to do because they were reasonably fair to start with thanks to peel-ply!

I'm going to roll 3 coats of graphite/epoxy on the bottom next week - will post some pics then.

I was pretty sure you would keep after it. You fellows from the land down under strike me as a pretty hardy bunch. I think your country is about the only place left on my bucket list that I would really like to see. I feel a kindred spirit to us in Alaska I guess.

Finally have some progress to show!
I have a fair bottom! No, I actually have a very nice bottom! :lol:
I think I have been a bit anal with getting the bottom fair and true to my satisfaction, but it is now looking good. No more sliding off the 18o deadrise slope or torturing my legs on the "sharp" strakes.

Image
Image
Image

I sealed my fairing with three coats of epoxy/graphite powder - West System epoxy and graphite powder (triple sieved) and CL's recipe for mixing.

I plan to paint over it with white two-pack Perfection polyurethane paint.

The transom has been faired - only the sides left to do. Shouldn't take more than a few days as they are already pretty fair due to use of peel-ply and they are MUCH easier to get at than the bottom! Fairing finished next week - painting the following week.

Have been working on the boat up to 8 hrs a day in order to get it done. "Work" gets in the way for a few days next week but I will be back into it on Wednesday.

Looking forward to the final "flip"!

340 gm should be enough to do your boat.

I've been working to get the hull ready for painting. Working in two parts, 1) the bottom and 2) the sides and transom. I want to get the bottom done first so that it can be hardening while I finish the sides and transom. When finished, I am going to flip the hull onto its trailer for completion of the interior.

4 x coats of high-build epoxy primer - sanded off nice and smooth with 180 grit paper on a random orbital sander, and I think I am OK to paint! :D

Image
Image

For me, one of the big unknowns in this boat building adventure is, "Can I paint this boat myself to a high standard"? I plan to put a full vinyl wrap on the hull, but I still want a good paint job underneath the vinyl and on the un-wrapped parts of the boat.

Now I know I cannot spray paint, so it is roll-and-tip or else pay for someone else to spray the hull. So the next skill set that I am exploring is roll-and-tip with two-pack polyurethrane paint.

1st attempt! Perfection undercoat - not perfect, but not too bad at all.

Image
Image
Image

I am a happy chappie! :lol:

I did this working solo and I think that the paint was getting a little dry by the time I got to "tip" it, so Mrs Barraman is going to get a lesson in "tipping" for the next coat.

The plan is 2 x coats of Perfection Undercoat sanded with 240 grit paper then 2 x coats of Perfection topcoat with the first coat rubbed down with 400 grit wet-and-dry paper.

It seems a pity to only build one boat, having acquired all these new boat building skills!

Glossie - yes the morning sun in summer made the garage just too hot to work in. The shade cloth makes a huge difference.

Rickk - was thinking about waxing the bottom. Don't think it needs it.......but while the hull is still upside down......? Would involve climbing yet again onto the bottom to do the work. Bummer!

When I started this I thought epoxy was "cool" stuff! Fascinating to work with. I am now having a similar relationship with two-pack polyurethane (liquid plastic) ! :lol:

Sorry guys, no boatporn video! Video camera played up and I was just too busy to deal with it. So you will just have to be content with multiple pics.

Put up the gantries and hoisted the boat off its strongback trolley. Fortunately we live in a quiet cul-de-sac.

The observant among you will pick that the gantries have swapped places in the pics below. The equipment hire shop only had one long gantry plank so we once the boat was rolled, we put in on the ground on some tyres and shuffled the gantries around so that I could back the trailer under it.

Rickk, I put a couple of 1/2" eye bolts through the upper engine mount holes which past experience had shown are close to the axis of rotation. Attached a couple of short load slings - gave the boat a bit of stability before and after the rotation.

OK, here's a little quiz for a bit of fun!

What does this hull weigh?

Bare hull, with only bulkheads and stringers.

Its 22' long, with an 8' beam and 2.6' of free board. Its covered with 3 x layers of 12 oz biax on exterior and 2 x layers on the interior.

Image

I'm gonna run it over the weighbridge tomorrow, so you will have to wait get the correct answer! :D

I've already weighed the trailer!

Jacques gives the completed weight of the Mangusta 20 as 875 lbs. This boat is a Mangusta 20 hull - upscaled by 10%

Yes, we are metric but I thought I had best talk your language.

Interesting that you and Larry both think it will come in, as is, less than a completed Mangusta 20.

My guess is around 400 kg, ie 880 lbs

Well, I still haven't built a boat yet. It's on the "I cannot wait" to-do list, but for now I live vicariously by watching all of yours.

I came up with my estimate as follows. First, I assumed that if you were building the "standard" version, you would be somewhere around 500 lb (of the supposed 875 lb total). This is a WAG obviously, but you've glassed the outside and have the inside core. I believe you still are waiting to glass more on the inside, so 500lb could be a reasonable guess. Next, since you've scaled up the design by 10%, this implies a 12.1% increase in weight since the surface area for pure scaling grows quadratically (cubically if you add more frames, etc). Thus, my 605lb estimate. Anyhow, it's a fun game to play. I'm excited to hear the results!

Re: BarraMan's Mangusta 21 barraboat in Townsville, AUS

Posted: Wed Jul 08, 2015 1:19 am
by BarraMan
Selever, interesting calculations. The bare hull is fully glassed with 3 x layers of 12 oz biax external and 2 x layers internal. All seams/joins are filleted and either triple or double taped according to the designers instructions, and at the moment it has 2 x extra bulkheads than the original design (ie I have yet to cut the middle bit out of the cockpit).

I just took a guess! Thought to myself that if the original design weight for the completed hull was 880 lbs, then mine was bare hull only at this stage, with stringers and bulkheads all fully glassed in - on the one hand - but 10% bigger on the other hand.

400 kg (880 lbs) seemed like a reasonable guess!

I knew my glass:epoxy ratio was close to the desired 50:50 because I have weighed out a couple sample glass "wetting outs". I also bought top quality ply - light and strong - beautiful wood.

We keep getting told that this building method produces very strong, light boats - but it is great to see it for yourself.

I posted the same question on my Facebook page for my mates to answer. So far nobody has come close - with perhaps the most interesting answer being 1400 kg (3080 lbs)!

Having flipped the boat upright onto its trailer, it no longer fits in the garage - so I built a tent over it to provide some shade and protection while I complete the build.

Where I live we talk about "Nine months of heaven and three months of hell", as far as the weather is concerned. We are presently in the 6th month of heaven - I hope to have it finished before "hell" arrives! :lol:


My fuel tanks are rota-moulded polyethylene (1 x 130 L and 1 x 170 L), similar to Moeller tanks.

Image

They are being installed mid-line over the keel, as per the plans. Fitting instructions call for them to be fully supported so, as their bottom profile doesn't match the hull, I am building a couple of cradles for them that will provide that direct structural support. The manufacturer says to allow a minimum of 3% for permanent expansion of the tanks once they are filled, so I have allowed 5% to be sure.

Need to get them in so that I can figure where all the chase tubes and drains will go. Will post pics when I finish fitting them.

2) I have fitted the fuel tanks - front tank = 130L (34 US gal) and rear tank = 170L (45 US gal).
3) Knocked up a rough side console to see how it looked in the boat and sort out position of guages etc

The console looks a bit boxier than I would like. I thought I might taper the upper part of it a bit, but I loose too much panel area and top space, and its about at the minimum required now. I will round over all of the corners on the real thing which should "soften" its look a bit.

I think my lay out will work OK - any suggestions? In case you are wondering, the engine control unit will be recessed into the starboard side panel.

I plan to mount another sounder/GPS nav combo unit on the top right of the console. On the job, the unit in the console will mostly be used as a chart plotter while the unit on top will be used as a sonar/sounder.

4) Also added some wood to the inside of the rub rails to increase the area for the decks to glue down on. Tried my hand at kerfing for the first time. Cool! It worked out great.

Heading into Justin Dwyer country next week for work but, I'll be back at it next weekend. Hopefully finish the chase tubes, foam under the floor and glue down the sole.

I had hoped to go fishing in Darwin next week but apparently guides in the Northern Territory only like to troll for Barramundi, and for me that is a brain dead activity. Had also hoped to take The Big Barra Boat up there for this week - but obviously I am dragging the chain there! :lol:

Looking great Lee. Making done good progress. :D

Give me a shout if you get a chance to catch up while you are in Darwin. The guy I recommended to you is away this week, which sucks cause he would definitely be casting at structure and drains in the harbour.

I'll email you my phone number.

Cheers

Hi!
I have found with the heat and radiation here in the North Kimberley,instruments don't stand up too well.The screens get sun damage and the black plastic body heats up and destroys sounders within a year or so.Ditto for the rubber toggle switches.Also the magnetic card hatches seem to get water inside when mounted at an angle
I made a console for my panga recently and covered the instruments with a screen.A bit like a little cabin so everything's protected from the elements
I put the epirb at the back of this and added a canvas flap which I drop down when on the mooring to keep the sun out in the mornings and afternoons or the rain beating in during the Wet.
The shade also gives you a clearer view of the screen if you are fishing with polaroid lenses.
I suppose you want the second sounder on top for some good reason,otherwise go for a smaller combo unit plus extra sounder or indeed two small combo units so you have Gps backup when your amongst the mangroves or out on the reef at night and one breaks down.
Might see you coming around Cape Londonderry one of these days.
Cheers!

Barraman your boat is coming together great but why if I may ask did you do this? It is not that your boat has a very difficult/hard flair or other difficult curves. Maybe I'm wrong but IMHO you were better off not kerfing that inner rubrail, this because I think you could glue it in there as it is, but probably I'm missing something? :doh:

What kind of motor are you putting on this? With the new motors you can run all the gauges via NMEA2000 to the chart plotters. On my Suzuki the factory gauge is just another digital NMEA2000 device. I'm not sure they even have an option for old wired gauges. You could save a bunch of real estate on the console if you are looking to. I run a lowrance 9" HDS touch. In chart mode when I'm moving I have speed, GPH, fuel remaining, trim, and engine temp along one edge of the screen. I use the factory gauge for rpm. With two screens you have plenty of space, I find its all viewable on just one. My t-top guy tried to get me to put the chart plotter up where it's in line of sight. I didn't but sometimes wish I had.

Hey! Thanks for the feedback and interest guys!

To answer one at a time:

Justin, when I couldn't organise to go fishing I changed flights and only came over to Darwin today (Monday). Unfortunately I have a very full agenda over the next couple of days, with early starts, full days and functions at night. I hope to be back up here later in the year so maybe we can catch up then. I get the feeling that the average NT Barra guide has a formula for putting the punters onto Barra ie trolling, and they are interested in doing anything else.

Woylie, the boat has a rigid canopy in its future which will give some protection to the console, but your bad weather flap is a good idea. The GPS combo unit I plan to put in the console is my third down the line unit so if being on an angle wrecks it I will just replace it. The one on top of the console is big and top of the line. For side scan image, the bigger the better. Plus I have the comfort of duplication.

Peter, like you I thought I could bend that wood around the inside of the rail - but it just would not do it no matter how much I tried. I wrecked a couple of pieces of timber trying so in the end I reverted to kerfing. So OK, I may have got a bit carried away with my kerfing - but it got the job done! :D

Bigtalljv, I hear what you are saying but........ The engine is a 250 hp Yamaha Vmax SHO. Call me spoilt but I want the combo in the console on chartplotter and the unit on top of the console on side/down scan when I am hunting Barra and don't like the idea of giving up screen to engine gauges. The gauges came with the motor so I figured I might as well use them.

glossieblack, thanks Michael. I have been putting in some hours when not working at my other job (like in Darwin now). I have been batching for a few weeks now while Elaine sorts out some family issues down south, so that lets me spend all day in the boat! :lol: It takes much longer than you think it is going to. I am supposed to be fishing up the Gulf in it next month - not gonna happen!

Some feedback on the layout
-It appears to be pretty busy, with a number of items behind the wheel. My preference is to keep the projected area of the steering wheel free, or put lesser-used gauges under it. Which helm setup? How far will the wheel stand off?
-Where does the throttle go? Side mount throttle on the side of the console, or on the gunnel? Foot throttle with separate shifter?
-I would be inclined to put both the jack plate switch, and the trim tab switch, just in front or to the side of the throttle/shift hand for easy manipulation with a (left) hand on the wheel
-How about reducing the number of switches on the panel, by moving the lesser-used ones away? I saw a neat setup that put the switches under the wheel facing down and back, like on the small kick panel you have. Cleans up the console, plus gets the switches out of direct sun and water. Just indicator lights were left on the console panel. Some switches can even go inside the console where they are protected.
-Have you picked an engine yet? Some of the recent ones have integrated digital info, so you can access engine data through the GPS screen. Or a combo gauge. Cuts down on dash clutter, though some things are nice as manual backup (water pressure?).
-Room for a cup holder on the top?

i'll get a picture of the gps screen with the data overlay but you are losing very little screen to the engine info, it's not a gauge picture, it's just a digital number overlay. I really think you want to simplify. I'd work towards getting the throttle on a binnacle on the dash and maybe moving the wheel to one side or the other. Is your engine fly by wire or do you have control cables? Not sure if you use it but also think about where the kill cord goes. I placed mine low on the dash behind the steering wheel and the wheel and the cord would foul. I made a little belt setup that solved that problem. here's a mediocre picture of my layout, you can see the key float, the key is blocked by the wheel. I took the key and kill switch out of the panel they came in and cut new holes so it didn't take up as much space.

As someone who just got finished pushing/pulling wires over the weekend. Just make sure you double the size for each chase, and DON'T use plumbing type PVC (like I did :x ) the 90 degree elbow are WAY too tight and make pulling wire really tough.

Also, I'm sure most of you guys already know this trick, but if you need to get string through an old chase tube just stuff some string in one side of the chase tube and hook up your shopvac to the other side. Took 5 seconds and no cussing :D

Otherwise, have fun. Installing the toys and making them work is a lot of fun.

Laminated a thicker panel for the front face of the console.

Image

Finished fitting my chase tubes today.

I call it, "Organized chaos"!

Image

Two rigid tubes for hydraulic steering lines and motor wiring harness (two other rigid tubes in the right side panel will house gear change and throttle cables), five larger flexible tubes and nine smaller tubes.

Stuff going hell, west and crooked! :lol:

Next up - pull all the chase tubes out and epoxy all the holes through stringers and bulkheads - and then put them all back in again ready for foaming under the sole.

Ventured into the unknown this morning!

I have started to put the sole, which is structural for this design, back permanently in the boat. The flotation foam will be based on Microlen sheet, but I intend to use 2-pack polyurethane foam to fully fill the spaces and for the awkward places where I can't get Microlen in easily.

The anchor well has no sole, but as the anchor rope/chain will be on a drum winch, I have made a false floor to that compartment with foam filling the space.

The space is only 15 L (4 US gal. to most of you guys!). So I decided to just use 2-pack polyurethane foam to fill it.

Image

What have I learned?

1) 2-pack polyurethane foam is wicked stuff! Way cool - but scary wicked!

2) 600 ml (20 fl oz) of combined Parts A and B makes a bit more than 15 L of foam! :lol:

Image

Turned out nice!

Yes Ilker, I cut the top off the "vanilla sponge" with a serrated edge bread knife and glued down a fitted piece of ply - then filleted and taped it in. Finished just on dark, so I will take a pic and post it tomorrow.

Lee,

I'm trying to work out the last steps you took in compartment #2. Did you slightly overfill with 2 part foam, place the sole on top with temporary weights, let the foam dry, trim off excess foam, then triple tape? Whatever, the end result looks great.

I'm currently building a shed so that I can start building my ST21.

I've never foam under a sole before either ! :lol:

This stuff stops growing after about 20 min and is hard after an hour. May still take a while to fully cure but it doesn't grow anymore. It had over night to do its thing before getting glassed in.

Its actually quite a small amount of 2-pack polyurethane (just enough to fill the small voids) - mostly Microlen.

I am a happy fella! Got it pretty well mapped out in my head how to get to the finish line from here - just a matter of doing it. Just chewing away at one of Cracker Larry's elephants. If you keep doing one thing at a time - you must eventually get to the point where there is nothing left to do. I think 2-pack foam was my last big learning experience - got it pretty well sussed!

Yes it does keep expanding, for at least a week if your 2 part foam is the same as I get from Bateau. I would not shape it completely or enclose it for 5 days in warm weather.

More seriously Tom, I guess its much of a much-ness. I looked at Moeller tanks but would have to had put a smaller tank in that location in order to get the clearance for the top fill.

With a potential 300L (79 US gal) on board, I don't think this boat is likely to be lacking in fuel capacity. :lol:

I'm figuring about 30 kts at 30L/hr = 10 hrs endurance/300 nm!

90% of fishing trips in my current boat I use about 20L. :lol:

That's very strange and to be honest I have a hard time believing that Tom, fuel pick up can be anywhere on the tank (most likely on top) it has a inner tube/pipe what goes to the bottom of the tank so that's not an issue, but the vent line as far as I know is always above the fill line on the tank.

My tanks: smaller upper tube is vent, as you can see it's above the fill line

Peter the fuel pick up is not a problem, your correct. 8) Lee's pick up and vent are on top of his tank. I only asked about the fuel fill, and he answered me to my satisfaction. :D As far as the US rules requiring the fuel fill being on top the tank that is a USCG thing as I recall. Maybe Larry can shed some more light on it. I lost all my notes on fuel requirements when my house burned down and my old computer looked like a pretzel. :lol: Here is a quote from one of the builders of marine gas tanks: "All fittings on marine gas tanks are required to be on top of the tank."

G'day Michael

Because those ports are in the floor of storage space under a hatch and not being walked on, I figured I could get away with:

"Inspection Port - Polypropylene ABS White " from BLA. They are about A$25 each.

For other inspection ports in high traffic areas on the floor of the cockpit, I have brass inspection ports - they are around A$100 each! 8O

Actually it´s the other way round. I´ve had it on both plywood and timber. If applied when the temp is still rising and you put quite a thick coat, it only takes a tiny amount of air trapped under the resin or in the wood to expand in the heat and form a bubble.
It´s no big deal, just sand the bubbles off and recoat. Make sure you coat after the hottest part of the day. You shouldn´t really do it with epoxy (although it is possible with some epoxy thinner), but I´ve had it happen with varnish too and a first coat really thinned down (like 1:1 varnish and thinner) helps seal the wood first.

p * V = n * R * T (ideal gas law)

If Temperature increases (and/or atmospheric air pressure decreases) the volume of a certain mass of gas (air) increases.
So a part of the air enclosed in the capillary wood leaves and forms bubbles.

Exactly. Warming air makes for out gassing bubbles. Some woods are much worse than others. Cooling air will soak the epoxy into the wood.

Been doing stuff that doesn't particularly lend itself to pics. Should have the cockpit soul fitted in the next few days and most of my chase tubes sorted as well.

Putting in some big days in the hope that I can still get it done this year - coming up 3 years in January! 8O

Front cockpit under sole area foamed and cleated. Foam is mostly microlen - 2-pack polyurethane foam has only been used in small hard to get at places and to hold the microlen in place.

Front cockpit sole panel fitted and ready to be glued down.

Now I gotta get some order into this!

I've pretty much finished the console, fitted a winch to the anchor well and sorted out how to fit my recessed engine control to the right side panel.

BarraMan, you are sure doing some nice work there. I am sure you can't wait till splash day comes around. It made me smile reading about you needing to cool your epoxy down before using it. I have to use fast hardener and put it in front of the heater for an hour before I use it or it is as thick as honey. Just goes to show the wide range of temperatures we can build in I guess.

Hang in there man!

I have finished the cockpit floor. The rear cockpit floor panel is/was, in my opinion, the most tricky part of my build with foaming and gas tanks and chase tubes and drains etc plus a few special features of my boat such as recessed seat pedestals (long story!) and provision for a removable port-side console.

I am working in the motor well at the moment.

I now have enough floor space to set up my workshop in the cockpit and should make good progress on the casting decks etc now.

Bought myself a camera for Christmas and will post some more pics shortly. I said way back that I am more of a builder than a documenter! Not much else going on in my life at the moment, I am working pretty much full-time on the boat, but I don't seem to have thinks to talk about every few days like Cracker Larry. You know, stuff like foiling armed robberies and searching for missing people - interspersed with other stories of his past life and adventures. Natural born story teller!

I only lost a week of building for Christmas and will lose another week at the end of January when we take a family holiday in Tasmania - that's the little bit land that broke off the bottom of Australia!

Swifty, I think the Mangusta is a great looking hull! Can't wait to hang the Yammie 250 on the back and see how it goes. If it goes as good as it looks I will be very happy!

Even built as designed, its a BIG boat. Stick it with steroids like I did and its really BIG. I reckon with a different top structure (light weight cabin) I could live in it - its as big as some motorhomes! :lol:

Drilled two holes in the bottom of the motorwell for water inlets.

Image

The holes in the sides of the motorwell are where my cockpit drains will open into the bilge. I had thought of running drains directly through the transom but in the end I decided that into the bilge will suffice, where 2 x 2000 gal/hr pumps will pump out the water as required or it can just run out the bung when the boat is being washed.

This boat is not likely to be in conditions where it might take a wave over the front and benefit from a self draining cockpit.

Now I need to fill these holes with epoxy/woodflour and re-drill for the fittings.

Michael, you can see my vac in the picture above - its a Pullman from Godfreys. Doesn't really matter - a cheap one cause it gonna be a wreck by the time you finish.

Get one that takes disposable bags rather than a bagless. Its much easier to just dump the bag when its full than mess about trying to empty cans etc.

For fittings I just made my own adapter from some different size tubing. Amazing how much dust you generate building one of these things.

I am sure you don't need me to tell you to get a good quality dust mask - I use a 3M brand. I don't think those white things that cover your mouth and nose are good enough. The dust that we generate is very fine!

That is one wild looking hull!

I bought a cheapo Shop-Vac from Kmart about 12 years ago for the garage, thinking it was cheap and disposable.
12 years on, it has sucked up tons of filler dust, 2k paint dust, chemically stripped paint, liquids of various sorts, metal grindings and the usual cleaning of car interiors.
Can recommend the Shop-Vac if you can find them locally. I also never bother running a bag on my vac, just the foam motor filter.
As for boat building dust, plain old paper particulate filters are all you need for sanding anything.

Thanks Lee for the vac info. Since I asked you the question, I went for a routine check up with my doctor, who's husband has been a professional boat builder for 30 years, and who's health is suffering as a result. Too much epoxy fumes and epoxy dust. She's insisted her husband get the best mechanical protection available - an integrated Festool vacuum that filters down to 3 microns + RO sander, and urged me to do likewise. Your health warnings, based on your health science background, is well based. Thanks. :D Now searching for a second hand Festool system in good condition. :)

Sounds good Michael! I have found my vac on the RO sander and a 3M dust mask have been excellent.
As for epoxy fumes ....... West System epoxy with slow hardener has negligible fumes. The fast and extra-slow hardeners are more volatile. For 2-pack polyurethane paint I use 3M activated charcoal cartridge filters - excellent!

About the filters when sanding, the plain paper ones are not comfortable, I can't work with them very long and they don't filter enough. I switched to the respirator type many years ago and while they cost a little more, the air flow is much better.
Breathing sanding dust is, I think, the most dangerous part of boat building.

agreed about the dust- years ago plain old wood dust was considered a nuisance, now they say it's known to cause cancer. The finer the dust the deeper it gets in the lungs, so you need a good filter to minimize the exposure. Spend the money on precautions or on the doctors- that high quality dust collection and effective air filters start to look like a bargain.

Cockpit floor finished, filleted and triple taped.

Image

At the back on either side are floor drains that drain into the bilge where 2 x 2000 GPH pumps will take care of any water. I was going to install scupper drains through the transom but then I figured that this boat is not likely to be in conditions where it is taking waves over the front so the drains only have to deal with washdown water and rain.

So what are the holes in the floor, you ask? Well its a long story! I bought these lovely big padded seats (pics will follow later) that have to go onto heavy duty pedestals. Unfortunately when installed with the pedestal base at floor level the seats are too high to be comfortable. Took me a while to figure a solution cause I really like the seats. In the end I decided to recess the bases into the floor and will fit a snug cover around the pedestal tubes. The space is drained into the bilge. All good!

Image

Image

The area below is in front of the motor well bulkhead. There will eventually be plumbed and insulated bait/kill/ballast tanks either side with two way pumps and an aerator, and start and house batteries in the middle area. Hence all the chase tubes.

Yeah, while the basic hull is to Jacques design, the decking etc is a Barraman work in progress! I think I have it pretty well sussed now but I have spent a lot of thinking time on it - drawing on the ply helps the process.

The blue tags on each end of the chase tubes are labelled with their intended purpose. I think I have it all under control - we will see when I get to wiring and final fit-out!

There is way more thinking that goes into a boat than building, but you look to have it all under control for sure.

I put the boat into secure storage last week while I took the family on a holiday to Tasmania. Picked it up today and while I had it out and about I thought I would put it over the weighbridge to see how it is going weight-wise.

Now I figure that the bare hull should weigh around 800 kg (1760 lbs) when completed. Given that I only have the front and rear casting decks, the cockpit sides and console to install, I reckon it should weigh about 700 kg in its present state of completion.

I was horrified to learn that it weighs 820 kg (1804 lbs) now! How did that happen? Its a solid build, but 120 kg (264 lbs) over weight ? :?: At this rate its gonna be close to 1000 kg (2200 lbs) on completion! I'm thinking, "I gotta chop something outta this thing"!

G'day Michael!

Have you done Bruny Is and surrounds in your boat? What a seriously beautiful place!

I am convinced that I was meant to be a cray fisherman but somehow got in the wrong que when careers were being given out. Park my cray boat in Oyster Cove Marina and run my pots every afternoon - sounds good to me! Pity its so frigging cold in winter!

My fantacy was to live in Stahan, run my cray boat and maybe moonlight a bit as a floatplane pilot - then I went to Bruny Is! If I could afford it I would have a holiday house there and spend the summer months in Tassie and the rest of the year in Townsville. :lol:

G'day Lee,

We've become absolutely hooked on cruising Tassie in our 44 footer every second year. It takes us about six week southbound from Noosa, and six week passaging home. Each involves crossing the challenging Bass Strait for 2-3 days and nights. In between we spend about 3 months cruising Tasmanian waters, including circumnavigating it. And the circumnavigation is the magnet - the awe inspiring challenge of sailing the west and southern coasts in huge Southern Ocean swells, safely navigating Hells Gates to access Port Macquarie and Strahan, and then safely navigating into the ultima thule of Australian blue water cruising - the wilderness of Port Davey. Huge areas of pristine landscapes and seascapes World Heritage or National Heritage protected. And when circumnavigating Tassie just about anywhere you drop the pick except the remote SW, there is wonderful boat to plate produce, and some of the best pinot wineries in the world. And then the relaxing cruising of Bruny Island after the white knuckle cruising of the west and south coasts. Did you sample the delights of Get Shucked on Bruny?

A couple of pics - the first is us anchored in the sheltered waters of Constitution Dock at the foot of Hobart, and the second below Mount Rugby in Port Davies.

Hoping to finish the ST 21 build in time for a cruise to Tassie in early 2017 (in the 44 footer, not ST 21!) Might the Big Barra Boat be going to the Australian Wooden Boat Festival in Tassie in Feb 2017?

Yes, I hope to take The Big Barra Boat to the Australian Wooden Boat Festival in 2017 - just waiting for the nominations to open. :lol:

My wife says I am crazy - she's gonna fly down and meet me there! Not sure what the issue is for her - its only a 6680 km (4148 mile) drive down and back! :D

Went out work on the boat this morning and discovered this!

Image

14 x 10L bottles of water that I used to weigh down the floor panels while gluing! They weigh 140 kg (308 lbs)!!!

So!

The empty weight of the hull at this stage of completion is actually 680 kg (1496 lbs)! Close to my estimate of 700 kg.

Empty hull weight of the completed boat should be around 800 kg, or just a little more!

I am a happy fella again. :lol:

Yes, I know where you are coming from. I agonised over this for some time.

I was going to fit these.

Image

but I became concerned about the size of the hole you have to make in the hull to fit them, in what is a high pressure area of the hull bottom .......... and then the manufacturer stop making them anyway!

Image

This is a work boat, not a race boat. It will spend 90% of its time poking along on the trolling motor and generally doesn't have to travel far to get to my favourite fishing spots. Normal cruise speed is only 1/2 - 2/3 of its potential top speed and where I mostly fish has a general speed limit of 40 kts anyway.

The pick-ups are quite small - just a couple of pimples on a big butt! The boat has ample power to handle a small increase in drag and the pick-ups are set far enough forward of the transom and the motor is set far enough back that I don't think they will interfere with the flow of water onto the propeller. Anyhow, they are in a position where I can change them if I am not happy.

I think that a clear advantage of this building method is what you can hide under a bit of tidy work! :D

I don't need these compartments beside the motorwell to be as deep as they are, so I put 20cm (8") of microlen foam on the bottom and covered it with a "false" bottom!

Image

Image

Image

Image

An acquaintance of mine lost his boat a couple of weeks ago. He and a mate were fishing off shore when they noticed the boat was sitting down in the stern. Further investigation revealed that it was taking on water, and before they knew it - down it went and they were dog paddling. Apparently they had no time to get any of their safety gear (there is a lesson in that!). If it wasn't for the fact that there happened to be a boat nearby that saw their boat disappear, they could well have been lost too!

The boat had NO flotation foam! New regs here require all boats built after September 2008 to have at least basic flotation, so I assume that their boat was pre-2008, but I don't know why you would go off shore in a small boat that won't at least stay afloat, even if it flips upside down!

My boat cannot sink! Not possible! I am aiming for level flotation but I don't want to put it through the testing required so I only put "Basic flotation" on its Builders Plate. However, it will have more than twice the calculated flotation required to keep it afloat, is closed apart from the cockpit which has 2 x floor drains into the bilge, and has 2 x 2000 gal/hr auto bilge pumps.

For some of the places I plan to go, the boat is my self-contained life support system!

As I understand it, over here, USA, your not required to have foam if your over 20' and in smaller boats the foam is supposed to be placed in such a way so the boat doesn't turtle ... which would imply placing foam high in gunnels or under deck platforms etc...

But nobody does that??

Yes, same here in Oz. Boats over 6M (call it 20') do not require demonstrated basic or level flotation. The boat that went down was under 6M and I am surprised it didn't have basic flotation.

My boat is over 6M at 6.7M or 22', but it does have basic flotation (its essentially a big surf ski!) and hopefully will have level flotation although as I said I have no plans to demonstrate either. It will, however, have the foam distributed correctly to give level flotation including high in the gunnels and under the elevated casting decks.

It also has all the heavy stuff (motor, fuel, batteries) all in the center-line and as low as possible to make it hard to roll over. The only things not low are the trolling motor and the anchor winch.

Foam! Don't talk to me about foam!

Why does my boat have lots of chase tubes? Cause its got lots of stuff, right?
Stuff like trim tabs! Where do the trim tabs go? On the transom with the hydraulic lines going through the transom into the compartments either side of the motor well.

Yeah? So what happens when some idiot puts 20cm of foam and a false bottom in those compartments?

YOU CAN'T GET THE HYDRAULIC LINES FOR THE TRIM TABS THROUGH THE TRANSOM AND UP TO THE PUMP !!!!!!!!!!!!!!

OK, so now I have 10 cm of foam and a false bottom in those compartments.

Not much you can't fix with this building method! :lol: Just another day in the life of a boat builder! What's a day, huh? Just 1/26,000nth of an average lifetime.

Ahhh the drama! come on man you know the solution even before you shout out the problem here! (let me also use an exclamation mark, only 1 :P ) With all the pics you have you can find the tubes, hit/open them by smashing them with a hammer and then rout them out neatly, if your router doesn't fit in there place the router bit in your drill, Jeeeezzzz !

Switch/fuse panels can move up now that I have shifted the trim tab controls.

I might move the pump switches over to the left hand side. That will make some room for LED reostats.

With all the rain I can't paint the decks and cockpit to the standard I want so I'll just do them with epoxy primer and polyurethane undercoat. After the fishing trip I'll sand it back, finish it properly and put the Seadec on.

OK, so I didn't make it. A major tropical rain event a couple of weeks ago blew me out of the water. I was putting in some BIG days, but made a few mistakes that I then had to correct, so I made a command decision to take a break from the build.

Have brought my tinnie back into play for the fishing trip next week and attached some of the toys from the BIG boat, ie Helix 12 sounder and the 360 degree transducer.

Don't have any screen shots of fish yet (hopefully next week), but I tried it out in the river this afternoon.

Almost there - only 1001 things left to do! :lol:

I've made 10 hatches - only 6 left to do.

Almost finished the console - will cut some holes in it soon.

Have been cutting holes in the transom for motorwell drains, underwater lights etc

Currently working on 2 x 130 L plumbed and insulated iceboxes/kill tank/bait tank/ballast tanks.

I am really slack - will post some pics later today. I said way back that I am more of a builder than a documenter!

Barra season is over for me so I am just taking my time and getting it right. I figure if I just keep doing stuff then eventually I will run out of stuff to do! :D

They're simple hatches - see here:

https://www.youtube.com/watch?v=tVvafzPnFaA

I don't need my hatches to be water tight, but I have a plan in my head to modify them if it ever becomes necessary.
What hinges are you planning on?
Recessed double hinges, ie the ones that let the hatch open 180 degrees. I don't need them to do that but I like the way they are recessed. I'll post a pic when I get a chance.

Rear casting deck coming together.

Image

Two front hatches are plumbed iceboxes/livewells/kill tanks/bait tanks. Rear hatch on the left is for trim tab and jacking plate hydraulic pumps and control cables etc. Rear hatch on the right is for fuel filters and rubbish bin.

The area under the middle of the casting deck will house the start and house batteries. Access will be through a hatch in the top tread of two steps up to the casting deck, and via a hatch in the motorwell/bilge bulkhead.

Been playing around with the set-out of my console again. Have swapped 4 x engine guages for 1 x multifunction guage - frees up lots of console space.

Image

Any suggestions before I cut more holes? :doh:

The indicator to the left of the "Key" is the autotrim on/off/indicator. If I move it further to the left I can see it through the spokes of the steering wheel and still get to it easily with the fingers of my right hand.

I will probably put a couple of reostat/switches below the steering wheel for LED lighting and the anchor winch, which I dont expect to use too often, will go on the side panel.

Hmmm - 2 x bilge pump switches needed! :D

for lighting I used Lumitech lights, the don't need any additional controls, you flip the power switch to change colors and to select the dim. when you turn them on they increase in intensity, a quick flip off-on of the power switch sets the dim level you are at. Same for color, another off-on and they go from white to red. They cost more but it's a lot less parts for things to go wrong, sometimes I am willing to pay for simple.

If you are putting in a kill switch and plan on using it make sure it's in a place the cord won't tangle with the wheel. Mine did and I had to use a little carabiner to make it hang low away from the wheel. I clip it to a belt so it's easy to take on and off.

Looks good otherwise. You might want to swap the TP indicator and switch. I assume you'd want to have a nicer view of the indicator than the switch.

the other thing I did that somebody suggested was multi-position switches. I rolled my own panels, toggle switches and a separate Blue Seas breaker panel. I was able to cut down on the number of switches that way and using plain toggle switches I could fit them in a smaller space.

Thanks for all that Jason.

Will look into Lumitech lights - sounds like the go. Cost? Well, I am so deep into this build that I have stopped counting. :lol:

The kill switch is part of the control box which is recessed into the right side wall, so its well out of the way.

I came to the same view with the TP indicator and switch. The TP is actually more easily viewed than the picture indicates but I am thinking of moving the KEY over to the left a bit and putting the TP indicator where the KEY is currently, with the Trim Switch underneath, a la the Jacking Plate Switch and Position Indicator.

I have a couple of Blue Seas switch/breaker panels with 6 x per panel. I suspect that I may only need to use one of those so my drawing on the console is probably overkill. Will probably put my bilge pump switches where I have indicated the lowermost switch panel.

Cheers

Lee

That's a great video. Thanks very much for posting it. I was going to do something similar but haven't gone through the figuring out part yet. That video will speed the process up significantly! I think I'll make my inside lip a little wider and rout out a recess for weatherstripping.

Good point, but I am unaware of a helm mounted lever for a Bob's Machine Shop jacking plate. The jackplate button is just in front of where my hand would be on the engine control unit - should be OK. My ski boat had trim buttons on the wheel, but I hardly ever used them - just the trim switch on the engine control unit.

Man I hate drilling holes in my hull!

Perhaps this blinker-type switch is what you mean:
http://www.bobsmachine.com/Pro-Trim-Jac ... 310000.htm

Here is mine mounted on a Bay Star tilt helm. Mounting it there was a bit of a pain, but it's in place solidly and I think I'll like it. Ordinarily you're supposed to route the cable from the switch alongside the helm and through a separate hole in the console. What I did was to pass the three wires from the switch through a piece of spare wire outer sheath and run that through the flexible skirt of the tilt helm just beneath the switch, then through a hole I drilled in the base of the helm as it lay against the console. That way the wires are out of view and there's not a separate (visible) hole in the console. I bet that could be done with a non-tilt helm as well.

OK, thanks for that. However it doesn't do it for me. My side console is set up differently - the engine controls are recessed into the side wall and when up and going the jack plate switch is just in front of my fingers on the throttle lever.

I'll give it a whirl and if I don't like it will retrofit some sort of switch on the wheel - buttons or lever. Lots of buttons to push on this boat - engine trim, jacking plate, trim tabs. :D

Although I expect my boat to get up and go, its primarily a fishing boat so I don't expect to be adjusting the jack plate while at full howl! :lol:

just to throw in something...terrible pic, but if you look close the wire for the Bob's Machine Shop switch comes out of the console just left of the binnacle, and the switch is mounted with a tie wrap just below the trim tilt.
Image

For me, one of the best uses of a Jack Plate is to be able to get on plane in shallow water. Jack the plate up, tilt the motor all the way down, hit the throttle and adjust the plate down as the boat lifts. Having the switch associated with the throttle or helm makes this maneuver easier. I just drop my right thumb down to the switch and still have the throttle in control. This was recommended by a friend who rigs a lot of commercial flats fishing boats.

BarraMan, I will soon be cutting hatches on my build and plan to follow your steps in the video (video is not available any longer). Two questions: what is the ply thickness of your deck and underdeck? Is there any flex to the largest of your forward hatches?

Thanks, Will

Ha! I knew the guy that made that video was a bit sensitive but that was unexpected. :lol:
Two questions: 1) what is the ply thickness of your deck and underdeck? 2) Is there any flex to the largest of your forward hatches?
1) My decks, and therefore my hatches, are 9 mm (3/8"?) marine ply, with 12 oz biax glass on the top surface only. The bloke who made that video used the same thickness ply as the hatch for the ring frame and ........ whatever you call the middle bit that fits into the ring frame. I thought that would add a lot of weight given the number of hatches I have. So I made a medium size hatch using 6 mm (1/4") ply for the ring frame and insert to test its strength. I was happy with the end product so all my hatches are 9 mm ply with 6 mm ring frames and inserts.

2) No, there is no flex in the largest of my hatches. I was going to make the ring frame for that big hatch from 9 mm (3/8") ply, the same as the hatch, but after making a few smaller hatches I decided that was not necessary.

The main thing from that video is that the minimum width of the ring frame glued to the underside of the deck is 50 mm (2"). My lips that support the hatch are 25 mm (1"), so the ring frames are 75 mm (3") wide.

Best of luck with your hatches.

Oh dear! What can I say but, "Damn you, damn you all"! :lol:

I have had a nagging feeling in the back of my head that I would have to cut my transom down further to accommodate the motor. A bit of an unknown with a big motor sitting on a 6" setback jacking plate so the cut was an educated guess.

While I tried to put on a brave face in the discussion of jacking plate positioning on the transom in "Re: Mark's PH18 in Toronto", I had an epiphany last night that it would be a great deal easier to cut the transom down further while here at home than it will be 1400km from home when I take the boat south to have its motor fitted.

Soooooooooo - this morning I attacked the transom and cut it down a further 80mm (3.1").

I was about to re-finish and paint the transom due to all the holes I have cut in it, so I figured that I might as well just go the whole hog and avoid another finish/paint job if I had to cut the transom down later.

Lots of dealers closer but the best deal on the motor was down south. I try not to have anything to do with the local dealer - who seems to think they have a monopoly. I am quite happy to travel - have lots of time on my hands and family down that way to visit. :D

Yes, Australia is a BIG country and for many Aussies, long distance travel is just part of life. For us, the 2000 mile round trip to Brisbane from Townsville to visit family was a Xmas holiday routine for 30+ years. Generally done over 2 days each way but on a number of occasions I have driven straight through in a looooooong day!

Its not like our roads are like those in north America either. This a bridge over the Bruce Hwy (Hwy 1 !!!) south of my home. Single lane each way and no sides on the bridge (No, that's NOT me in the pic!). Most of Hwy 1 is a single lane each way.

Barraman,

I remember once doing Innisfail to Brisbane on the Friday to drop off my brother who lived there, got drunk with a mate on Saturday then back home to Innisfail on Sunday. 1,600km each way, what a great weekend though.

And to think that 1600 km's is still only half way to Melbourne... It's a big place alright.

Mate I have heaps of family in Townsville, I would love to see your boat one day when I'm down there. I'm in Atherton but try to get down a couple times each year.

Keep at it, looks great!

My decks are 70 cm (28") above the sole, so to help an old fella like me get up and down I have built steps front and back. The bottom step in both contains a seat pedestal fitting that can be access through a round access plate to provide some extra seating.

The top front step has a hatch that opens for tackle tray storage, and the top rear step has a hatch that opens into the compartment that will contain the start and house batteries and the pumps for the livewell/ballast tanks.

Still lurking around mate, no boat building though. I am nearly ready to start again :)

Having two kids under the age of 3 really leaves no time, and when I do have a little bit of time I don't have the energy to hit the shed (because that is usually after 8pm at night). On top of all that I have been working a second job to get my marine qualifications, but I have finished the "Master" component now, so I can drive boats up to 24m within 100NM of the coast and I am starting my Engineering course next week, so after that I will duel ticketed as a Master/Engineer. Then I will have two good tickets and I can start to look for jobs to change this career of mine. So it has been a really busy year, but is well worth it.

I will be starting work on the boat soon, I nearly did a night last week ;)
I want to have it flipped back over before the wet so I can finish the strakes and fairing.

In the mean time I just perve on all the boats in here.

Keep it up mate.

Way overkill but surprising how neatly they have been accommodated. Those that run to the side console come in either from underneath or the right-hand side.

I have basically fitted a chase tube for every application I can think of, without much consideration for doubling up.

This boat will have lots of stuff in it or attached to it - much of it duplicated or triplicated (?? :D ), eg it has 3 x networked GPS sounder combos with associated power, GPS puck and transducers - one in the console, one on top of the console and one on the front deck. The Helix 12 on top of the console has two transducers - one on each side of the transom, a down/side scan and a 360. Each of two fuel tanks has 4 x chase tubes - fuel line, 2 x tank breathers and 1 x fuel tank compartment breather. It has 5 batteries, 2 x 12 V and 3 x 12=36V with associated engine and external charging, etc etc etc

It all adds up! :lol:

Breather outlet for my fuel tanks. The tanks have two breathers each and the fitting instructions call for a breather on the space the tanks fit into.

Hi Lee, great job, buddy.
I like the scaled design with the "double hull" foamed up. I did the same(double hull foamed). Where are you with weight - any idea? Cool trailer as well.

The last time I had it out and about I put it over a weighbridge. The bare hull, with empty fuel tanks installed, is going to come in around 850 kg (1870 lbs). Perhaps a bit heavier than I expected, although I really had no idea given the up-scaling and the custom deck layout, but it is a very solid build. Its still much lighter than a comparable factory 6.75M metre (22') boat of similar style.

The 250 hp Yammie that's going on the back should push it along nicely - if not I'll trade it for a 300! :D

I think I am only a few weeks away from the "splash". Apologies for the lack of boat porn, but there is not much to see and its hard to show its best side while its in the tent. When I have finished painting the decks and cockpit I'll pull it out for a photo shoot.

Lee did a fast calculation for you with the 1870 lbs as the hull weight added 600 for the 250 Yamaha and cables and 500 for people, gear, ice and beer. :D Didn't know how much fuel you had so you will need to reduce speed by 1/2 mph for every 10 gallons.

With the 250 you should top out in the high 40's to low 50's that is miles per hour.

Thanks for that Tom.

40 kts would be fine by me as the places I mostly go have a 40 kts speed limit.

I can carry up to 80 US gal in two tanks, so if that knocked it back to 30 kts when fully loaded, then that's OK too.

Finished fairing the bilge and sealed with grey pigmented epoxy.

Image

The transom is at the bottom of the picture. The large holes in the transom are for underwater lights (I am told that crocodiles hate lights! :lol:). On either side are the outlets from the cockpit floor drains. The two pipes in the bottom of the bilge are inlets for seacocks that will be connected to my livewells/baitwells/ice boxes. The large opening in the bulkhead at the top of the picture gives access to the pumps and plumbing - it will be closed with a screwed down hatch. At the bottom of the bilge is a shelf that will house 2 x 2000 gal/hr bilge pumps and auto-switches. The drain for the bilge is hidden under that shelf. The large pipe at the upper right of the pic gives access for the motor battery cables to the start battery which is housed in the compartment just forward of the bilge.

Any thoughts on a prop for this boat?

I am not looking for outright speed as mostly where I fish has a 40 kt speed limit anyway, and I think 40 kts is probably fast enough for a 22' boat. Not that I mind a bit of speed - I used to ski race when I was young and care free!

40+ kts with a decent load (including 80 US gal of fuel) on board would keep me happy. :D

Hi Lee, great going :D How did you ever get that grey saturation in the tinted epoxy ? Man, I gave up with that system and went for Bilgecoat in my lockers but even that takes 3-4 coats. White does not cover well at all.

Hi Lee,
Yeah, agreed - those tight corners are a pain - the 'large-ish' flat areas seems little consolation for the corners and seems...
help me out :
The holes on the transom, 4 x12/13mm mounting holes for the motor, 2xmotor well drains, 2xtrim tab jack cluster, 2xtrim tab mount clusters and n bulge drain. What are those 2 big ones just under the motor?
Are you mounting a 2 stroke or 4 stroke yammie?

Cheers, mate - great work....bummer about the AB's

Sorry bud, something else I just spotted - I'm sure you've done your math and checked the motor but the angle of the motor well cover seems very steep. Might just be a perspective thing. Do you have enough space to tilt back the motor all the way?

Peter is correct - underwater lights.

4 stroke - I hope that my 2-stroke days are behind me.

You are very observant! There is a reason I did it like that. I have a hatch at the back of that compartment that opens into an area under the rear deck that houses the pumps for the bait tanks etc and the start and house batteries. It can also be accessed from the front.
Image
I think I have worked it out correctly - will soon find out! The hydraulic jacking plate has a 6" setback and a 6" lift. If necessary I will fit a tilt limiter.

Yes Justin, its built with ease of access to most things.

Pumps are easy to get at through that hatch in the front bulkhead hatch of the bilge.
Start and house batteries are easy to get at through the hatch on to top step of the rear stairs.
Fuel filters are in the compartment on the left of the motorwell.
Trim tab pump and jackplate pump are in the compartment on the right of the motorwell .
The console has a panel on the top that lifts off and a door on the side.
And 40+ chase tube go hell-west-and-crooked to every corner of the boat! :D :lol:

Small router work like this can also be easily done by hand, all it takes is a sharp (sunk) router bit and eye and a steady hand, saves you work making templates for everything. 8)

Peter, that was Plan A. I quickly moved on to Plan B! :lol:

Maybe with a bit more practice I could do it freehand but I just wasn't game to take on 30 hinges that way. :D

Speaking of which, I just installed some drawer slides for a drawer I made for the wife, and it was about $12 for the pair of them, and they weren't even the cheapest as they had the soft close feature. So for $12 the metal ore was mined, shipped, refined, shipped again to a foundry, extruded, machined, shipped to an assembly plant where it was assembled with other parts shipped from elsewhere in an equally complicated process, tested, packaged, packaged in a crate, packaged in a container, trucked to a ship and loaded. Then the ship was fueled, maintained, and piloted across an ocean, where it was unloaded, trucked to a warehouse where my stuff was inventoried and stored for awhile until I placed an order through a cable to a station that uploaded my wishes to a satellite, which transmitted them to the warehouse where either a robot or person retrieved the slides from their shelf and put them in a new box and loaded them on a truck which brought them to a substation which put them on another truck which delivered them to another substation where they were loaded on a smaller truck and brought to my door, for $12. Yikes. I'm exhausted from that. I need a nap.

Unfortunately the lake we had available for testing the boat was very crowded at the time. We were more focused on not running into anyone than performance - and we were too busy grinning from ear to ear to write down any figures!

At the moment I can't even give details of the prop because I am away from the boat. It's 21" pitch but I don't remember the diameter or style. Enough to say that it works very well - holds on like crazy, even when "semi-surfacing". The prop is just hitting 6000 rpm at full throttle.

We have propped the boat for hole shot and pulling power rather than for top-end speed. Where I mostly fish is speed limited to 40 kts.

With a squirt of power the boat gets onto the plane in a boat length. It runs like its on rails, even at high speed and really hangs on in tight turns. If you pull it at speed into a tight turn and feed the power ti it, you can get into a controlled power slide.

The hull/motor combo seems to have no vices. With engine trim, Jack plate height and trim tabs, it's gonna take a while to figure out how to drive it and to find its sweet spot for cruising.

So far, the best I have seen is 44 kts at 6000 rpm. I think it will do better on this prop once I figure out how to drive it.

I think it will cruise around 30 kts at 45000 rpm burning about 40 L/hr.

The power and performance of the Yammie 250 hp Vmax SHO is awesome! It feels like it just wants to GO!

I'll post more pics and some video shortly.

I have to say you did a great job 8) But and there it comes :P imho you you raped the MG design, probably I missed something but I still don't get it, why make this into a fishing platform, while Jaquess has better ones out there? But again you did nice work 8)
Congrats on the splash 8) 8)

"Raped"!
"Raped"?

I am deeply offended! :lol: I think I have treated Jacques design with respect.

So what would you suggest as a better alternative Peter?

Here are the requirements:
1) Stable casting platform - with a large casting deck up front and another at the rear to accommodate at least three fishing together.
2) Able to handle some rough water with safety (min 18o deadrise at the transom) while maintaining useful cruise speed - the Gulf of Carpentaria is relatively shallow and can really stand up in windy conditions
3) Min 6 meter length to handle the Hinchinbrook Channel's short frequency/amplitude chop
4) Able to accommodate appropriate Minn Kota trolling motor and batteries (in this case 3 x 120 Ah for a 112lb Ulterra iLink)
5) Range (out and back) of at least 2-300 nm.
6) Plumbed kill tank and live-well for dealing with dinner on trips to remote areas and large enough to double as ballast tanks that can be pumped up to throw a good wake for wakeboading
7) Plenty of storage space for gear etc
8 ) Useful ski/wakeboard boat able to pull up two serious single skiers
9) Big enough to intimidate saltwater crocodiles up to 5 meters
11) High enough sides to keep fishos safe from saltwater crocs that see them as lunch/dinner
12) Large enough cockpit for at least two fishos to be able to roll out their sleeping bags for an over-nighter
13) Looks the business and reflects my personality!

My "raped" Mangusta 22 easily meets all of the above criteria!

So what would you suggest Peter?

No, not finished - just splashable. Still have quite a lot to do - maybe another years worth. The decks and cockpit are only done with high-build epoxy primer, so they have to be painted. Some of the hatches have to be fitted with recessed hinges. Cleats and rod holder to be fitted. Anchor winch and trolling motor installed. Lights etc. Rub rail. Second console, rod locker, hard top.

On another note, is it me or I am reading some friction with Peter or just friendly teasing :( :roll:

Other than the mangrove that could be over here! Those things seem like a very angry mix of our trout and reds. Very angry. We do have a lower density is alligators than you of crocodiles. Which all means you have us in the angry animal scale. Also explains the amount of liquor every Aussie I've ever met puts away at breakfast. Hell, it seems even the water tries to kill you lot. I drink more too..

Had the boat out today in some of the worst conditions my favorite fishing spot can throw up - big tides, strong winds and shallow water making the sea really stand up at either end of the channel.

On a rare calm section of water I think I may have found a "Sweet Spot" in engine rpm/jack plate height/trim tab setting/motor trim.

3800 rpm/30 kts/30 L/hr (8 USgal/hr)

Interesting that a 6+M boat still managed to find a couple of "holes" but overall, very well. It just eats the usual Hinchinbrook short chop and even in the really rough stuff never felt unsafe or out of its depth. Apart from a couple of waves over the bow, its a very dry boat in the worst conditions I am likely to be out in.

The hull continues to exceed my expectations.

If it made you happy in the worst conditions you plan on being in I would say that is about all a man could ask for. I do not think it matters how big a boat is they all will find a hole every now and again. The idea it eats the normal chop has to please you very much.

What a useful forum this is!

After my asking about s/s fabricators on Glossieblack's Skinnydip thread and floating the possibility of getting some side rails built Florida and shipped to Australia, I was contacted by someone in my town who does excellent marine s/s work. While I was vaguely aware of his boat manufacturing company, I had no idea that they took on outside work like mine.

Problem solved - I am a happy fella.

Well! I was kinda surprised to see my build thread pop up again, Michael.

"Enjoying the fishing"? Yes maybe. Lucky they call it fishing not catching cos I haven't been doing a lot of the latter. In some ways I think it was a mistake to put the boat on the water before it was completely finished - but I just had to see if it was gonna work right for me, and we have had a lot of fun with it. The best bit is that it has exceeded my expectations in every way - performance, handling, as a lure casting platform - even as a skinny water boat. I just love the thing and so does anyone who sees it and particularly those who get to go fishing in it.

I have been busy with some other stuff this year and unfortunately have not made the sort of progress towards completion that I had hoped. That is about to change! I have an engagement party for my second son and fishing buddy coming up later this month, followed by a work trip to Tom Price and Fitzroy Crossing in Western Australia. As soon as I get back in early July its full on boat building. The motor is coming off so that I can fix an issue with the motorwell (just cosmetic - nothing serious), finish painting the boat to my satisfaction, complete the plumbing of the livewells and install the rub rail. As you know I now have someone local to do some s/s rails for me. Got a bit of tidying up of wiring that I would like to do as well, and yes, the seadek to go down.

We are going to fish the McArthur River out of King Ash Bay near Boroloola in the NT in late September so I need to get it sorted for that.

Cheers

Lee

I've given this some thought since you asked the question, Given that I took Jacques basic 19' runabout design, upscaleed 10%, put fore and aft casting decks on it, built it with a side console and put an electric trolling motor up front - I am a bit surprised that it worked out the way it has. No, I can't think of anything significant that I would change.

Had I known that the motor/prop combination would happily run as high as it does, I would have done the transom a little different - but that's minor.

I am surprised that the boat goes as well as it does. Not sure why am surprised, but I am. As I have said before, the boat has exceeded my every expectation.

I see (and said) this in post splash reviews. I wonder why? I know I screwed a lot up and figured it would impact performance. I wonder if there's a conditioned thought that the pros are able to do something the basic home builder can't?

That or JM is a wizard in designing hulls so efficient that they aren't impacted by the inconsistency of home builders...

Re: BarraMan's Mangusta 21 barraboat in Townsville, AUS

Posted: Sat Jun 17, 2017 7:25 am
by BarraMan
Interesting isn't it!

JM's plan's are fairly basic compared to some other designers but deliver a well designed hull (or we assume so). Then some of us at least do stuff to it that we think will suit or application.

In my case, after looking at lots of other similar hulls and reading a bit, I put reverse chines on my hull. They are not on Jacques plans. I suspect JM would say that the hull doesn't need them, and he is probably right.

If you look back to some early questions in my build you will see that I was concerned about strakes - what shape, how many etc. The plans give very little detail just a couple of lines indicating where you might put strakes. JM told me that the hull didn't need them anyway. Because I wanted to have the stringers sit over the bunks on the trailer, I only put one strake either side on my hull. They are fairly "aggressive" - triangle in cross-section.

So how did it all work? Well, I can put the hull on the plane in about a boat length with a burst of power, or if I let it come up slowly it will do so around 15 kts. It corners like its on rails - if I pull it into a tight turn at speed (>30 kts) and feed the power in I can just get it to start to slide, with no obvious vices.

I went to a lot of trouble to make sure the hull was true and square etc to within a couple of mm of tolerance and I put a lot of work into ensuring that the bottom was true and flat, with no hook or rocker.

But of course you have no idea what is going to do until you put it in the water.

I have had it up to 48 kts and it is rock steady at that speed, but its sweet spot for cruising is around 27 kts.

Tom, you were pretty close to the mark some time ago when you predicted "high 40's/low 50's mph" for this boat. If it was propped for speed it would go faster but it's propped for power - and it has heaps of that. 25-30 kts is nice cruising for a boat that size, but it's fun to open the tap occasionally!

"Occasionally" being the operative word! At 6000 rpm and 48 kts (55 mph) its burning 80+ L (21+ US gals) per hour! :D

Even at 55mph you are still getting over 2.5 miles to the gallon. That is pretty darn good in my book.
I had one boat that would run in the high 40s but it was a rare day I could run it that fast. And floating hazards come at you awfully quick.

The 52 does look fine. I used the smaller one some years ago on my LB22 and, with no previous experience of any kind, found it an easy, no stress task.
Wouldn't use anything else now.

Yes, it's very easy to install and looks great. I went with the Radial 52 as I thought it was the best look for the scale of the boat.

Yes Tom, I know what you mean. The black track under the rub rail gave a contrast that looked really good. However there is a master plan!

I am working towards a vinyl boat wrap that will cover most of the white and provide a lot of contrast. How will it look? Won't know until I try it. The other issue here is that anything black just gets sooo hot in our north Australia sun! Even white surfaces can get too hot to touch or walk on in bare feet.

Here's the wrap that is going on the boat.

Well, my boat has been put to the ultimate test and realised its destiny. I started out to build a boat that would take myself and a few mates to some of the most remote fishing spots in Australia, chasing the illusive Lates calcarifer ie Barramundi.

Over the last week of September we towed the boat some 4000 km return to fish the McArthur River system in the Northern Territory. From a cabin base at King Ash Bay we fished hard for 6.5 days straight, travelling up to 160 nm in a day to get to our chosen fishing spots and spending 12 hrs on the water most days. Each day involved at least a 30-40nm run down to the mouth of the system, while on 4 of the days we traversed well out into the Gulf of Carpentaria to get to a "special" creek or headland.

The boat carried us in safety and comfort wherever we went and performed flawlessly all week. The Gulf is notoriously shallow and the sea stands up pretty well in a bit of wind. We travelled mostly around the boat's "sweet spot" of 26 kts and even in rough water were able to maintain 20-22 kts. I was surprised that it ran happily in 0.6M of water, although that made me quite nervous.

The big white barra boat looks like a bit of a pose, but it performed perfectly in its intended role. We caught heaps of Barra when most were struggling and we had a ball!

I'll post some pics when I round them up from the crew.

Hank, there are more photos and videos of the boat at work in the "Anything else and for sale/Anyone fishing?"

But here's a couple for your enjoyment.

Image

[youtube]https://youtu.be/zME3Igl0YYo[/youtube]

I don't recall if I have ever told the story behind the building of my boat, but I'll tell it again anyway. I am sure that there are many and varied reasons why people embark on this journey, and my story is just one of many.

I got into Barramundi fishing with my younger son when he was about 12 years old (now 31). I was never into fishing but he asked me to take him fishing - so I did. Long story - but I ended up buying a small alloy boat (what we would call a tinnie) and soon after he caught his first barra (72 cm) ever on his 2nd or 3rd cast of a lure and a couple of weeks later I caught my first ever barra and joined the "Metre Club" with a 104 cm fish. He and I have been hooked on lure fishing for barra ever since.

A few years ago I read a story about some blokes who when barra fishing in a remote river up the western side of Cape York in northern Australia and had a blast catching some big fish. I decided that that would be a really cool thing to do so I started looking out for a larger boat with which to do the same thing.

Parallel to this thinking I have always had a thing about building a boat. It started out as a canoe when I was quite young and grew in scale as I did. I never got around to actually doing anything though until I started this adventure. I have earned my living mostly with my head but I have always been pretty "handy", so I like to think that there has always been a boat in me wanting to come out.

Once I merged the two thought processes I started looking for a suitable boat to build and eventually gravitated to the Mangusta 20 - modified to suit my needs.

My specs were:
1) a hull that while having good stability for lure casting, could also handle some rough water to get us to and from remote locations safely.
2) large enough to intimidate any large crocodiles (4-5 M) that we may encounter and with enough free-board to be a barrier to any crocs joining us on board.
3) plenty of get-up-and-go to do double duty as a ski/wakeboard boat on family holidays, and cause I just like power and speed!
4) long range - ie at least 200 nm out and back with and appropriate safety margin.
5) something that I could modify to have large casting decks fore and aft.

So I built the Mangusta 20 hull, upscaled by 10%, built is as a side console with fore and aft casting decks on it.

The build coincided with my semi-retirement so it gave me something to do, and after a 45 year working life I was fortunate enough to not have to think too much about budget!

The boat has exceeded all of my expectations and I, and everyone fortunate enough to have fished from it, just love it!

Thanks for sharing that and the story with your son. It is always interesting to know why these boats are built. I am sure you will have many years of fishing on her and your son many years after you can no longer fish. :( in 20 or more years. :lol:

Its a year since I "splashed" my boat!

Image

Since then it has done service as a ski/wakeboard boat over the 2016 Christmas/New Year period - about to be repeated, and has fulfilled its destiny as a Barramundi fishing platform. It has taken us in safety and comfort to one of the most remote parts of Australia in pursuit of that legendary fish, and not missed a beat in the process. The boat attracts great interest everywhere it goes and those who have been fortunate enough to be on board continue to rave about it. Anyone who knows the story of my build, the first question they ask me when we meet is not, "How are your wife and kids", its "How's the boat"?

The big Yamaha SHO vmax has just over 100 hrs on it and is booked in for a service next week.

Observations/regrets?

1) I have the luck of the Irish. From a place of complete ignorance I messed with Jacques Mangusta 20 design - and got away with it! I can't think of any negatives with the hull - even at 40+ kts.

2) Its not finished! Maybe it was a mistake to splash it before it was completely finished but if I hadn't done so we would have missed out on a bunch of fun. New Year resolutions include finishing the decks and installing the SeaDek that has sat on our lounge room floor for the last 18 mths. Get some S/S rails made and installed, and get it wrapped. And sort out the bird's nest that is the wiring hidden in the console. Somewhere is the future is a T-top.

3) I was initially a bit concerned about the fuel consumption, until one of my mates made the following observation, "If you install a 250 hp Yamaha SHO vmax, you shouldn't worry about fuel consumption" - so I don't! My other boat is a little tinnie with a 40 hp 4 stroke Yamaha that runs all day on the smell of an oily rag. Once I found the sweet spot for the big boat/motor combination I became much more comfortable with the fuel consumption - but there is a price to pay for running a big boat at 40+ kts for any length of time.

4) My fishing calender is full through to 2020, with numerous local trips planned and at least two big trips a year to remote places in northern Australia, but I think the highlight of 2018 will be the launch of "Skinnydip" and the Bateau Builders Downunder get together in April.

Launched the boat in the beautiful Brunswick River this morning for a bit of a run around the patch and to wet a line.

Image
Image

To get to the fishing spot we had to take the boat for its, and my, first bar crossing. Now if one is going to learn the ropes with crossing bars then one might as well start on one of the most notorious bars on the east coast of Australia.

Image

There was a reasonable easterly swell running so the bar was entertaining and outside a bit sloppy. The boat performed well and showed itself again to be very dry.

On the horizon is Cape Byron, the most easterly point of the Australian mainland.

Anything you want to know about crossing bars, I'm your man! :D

OK, I thought I should follow up on the above with a few points, based on my lifetime of experience.

I find that its best to try to maintain an air of confidence, with just a bit of swagger in your step as you cross any bar. Keep you eyes up but don't make eye contact with the bar bully unless you can fight, and make sure that you don't bump into anyone or anything - cause you might spill your beer!

As for the Brunswick River bar? I wouldn't go anywhere near it myself. My mate - ex pro-fisherman of many years of experience crossing that bar was at the helm this morning. He made it look easy!

His only comments were, "The boat is @#$%ing awesome" and "Man this thing has some get-up-and-go when you want it"!

I was just looking through the last few pages of this thread and realised that I said that I would post more photos from our fishing trip to the Northern Territory - and then failed to deliver. So here are a some more!

Refuelling stop! 250 miles between gas stations here - just beyond the range of the Discovery towing the boat. Need to upgrade to a long-range tank!

One of my favourites - heading out for a days fishing. The boat was sitting on 28 kts when this was taken.
Image

Image

The crabbing industry in the Northern Territory is dominated by Cambodian immigrants. Many of the rivers have rough work camps set up on the remote rivers. Makes you think you are in SE Asia.

The upload from the GPS tracker in the boat shows where we went.

Yes Michael, got home about 19:00 on Wednesday after a 1.5 days drive Toowoomba-Roma-Townsville.

I am very happy with the trailer. It tows very well - different from the old one in a way that I can't quite put my finger on - but very stable and easy to tow. Interestingly, although it weighs 100 kg more than the old one, the Disco was burning 17+ L/100 km rather than the 18+ L/100 km that I am used to with the old one. That equates to at least 50 km more range before the low fuel light comes on. Suggests to me that all was not well with the old trailer's running gear.

Image

Image

Image

I got them to build me a geriatric's ladder at the front - I'm not getting any younger! :lol:
Image

A couple of spare hubs and bearings tucked away behind the stone guard.
Image

A roller ladder under the keel.
Image

And roller supports to keep it level on the trailer.

The boat drives on an off very easily and there is a "Boatcatch" just out of frame in pic five.

I tow very little on unpaved roads, but I do tow on narrow sealed roads with unsealed shoulders. A passing vehicle can shower the boat in stones. That stone guard is a mesh that provides protection without much wind resistance.

That's cool - I've never seen a boat with a shield of any type. We have "love bugs" here and they congregate around areas of high vehicle exhaust - like a road/freeway. In some places they are like driving through a very dark fog. They are caustic and when they decide to "die" on the front of a car it can eat the paint off.
Very nice and well thought out trailer.

I take it that when driving down the road with no traffic you stay on the black top but have to move over for traffic. If that is the case it is easy to see how lots of stones would be thrown up by oncoming traffic.
If the road is out in the bush with not too much traffic it would sure keep the building cost down. All in all not a bad idea.

The Gulf of Carpentaria is very shallow. In that video we are at least 5 miles from the nearest land - running along in only 6 ft of water. Running down the McArthur R we are often in only 3 ft of water - doing 25 kts!

No Michael, the rubber moulding has rolled off the plastic base - I assume forced off by the pressure of the water.

Not sure what I'm going to do now. I think I will replace it with one where the moulding is fixed to the hull with the screws covered by an insert.

Not happy! The Tessilmare wasn't cheap.

That's pretty pathetic performance by the Tessilmare. Hopefully they'll replace it with another one of their products that can be irect screwed to the hull with a cover strip, free of charge.

On a brighter note, the video camera setup is brilliant! :D

Haha, yes that is one of five cameras on the boat for fishing.

I think a run up the Noosa R with that camera running will be kind of cool for the guys on here.

To answer your earlier question, the new trailer performed brilliantly. Believe me, a 4000 km round trip to the gulf will find the weak points in any of your equipment - tow vehicle, boat, trailer, motor or fishing gear!

We stopped along the road and tried to help a number of crews who's gear just wasn't up to the challenge!

I worked out this morning that I have towed the boat about 4500 miles since picking it up on its new trailer a bit over a month ago! :D

Most recently about 900 miles from home (Townsville) to Brisbane in preparation for the voyage of discovery up the Noosa R with Michael Glossie next Tuesday.

I am really looking forward to it!

Not to worry. It doesn’t make any difference to me if I live in Brisbane or Townsville - fortunately our son has an apartment in Brisbane that we can use.

I’m not going home without doing the Noosa R - I don’t need to be back in Townsville until then end of the month.

I, once again, had the “Englishes” property knackered. Y’all speak Australian.

Wheny then 14 yr old son and I where in England a significant number of years ago, our host advised us “you’ll want to put on your rubbers for walking around this morning”. Her husband was keen you the us slang and burst out laughing at my son’s obvious discomfort.

It is a story he retells often.

My father-in-law liked to recount the story of an English woman who came to visit New Orleans and after a trip to the grocers commented, "I believe the man at the shop diddled me". The response was "you should consider yourself lucky!".

I was privileged today to be the guest of Barra Man (aka Lee) on a sortie in his Big Barra Boat from Noosa up the Noosa River and Lakes system into the Noosa Everglades. Amazing boat, amazing adventure. Thanks Lee!

It's Lee's story to tell, and his video to show. In the meantime dear forum readers, please give the boy some space. He's now driving for hours back to his family.

But let me report this. Lee has built an amazing bespoke fishing machine.

She performs like a competition speedboat courtesy of JM's hull form, and she's provides a stable and secure fishing platform, courtesy of Lee's above waterline freeboard and deck layout design refinements.

She can chew up big distances fast courtesy of her monster Yammie, yet like a dainty ballerina, gracefully manoeuvre or stay perfectly in place courtesy of her highly intelligent Minn Kota electric trolling motor.

She's Lee's Bespoke Big Barra Boat! She's a one off. And she's a beaut! 8) 8) 8)

Here are some maps to show you all where we went (You can download them here: https://www.msq.qld.gov.au/Boating-maps ... ast-guides). Search "Doonella St, Tewantin, Qld" in Google Earth for the general lie of the land (Map 4). The boat ramp that we launched from is at the end of that street, and headed north.

Those big lakes are no more than 3 - 4 ft deep, at best!

The maps don’t really give a good indication of their scale. Lake Cootharaba on map NR2 is massive. OK, nothing like the Great Lakes, but big for here.

We got to Camp 5 on the Upper Noosa R before we had to head for home due to fading daylight. Thank God for the "snail trail" on the GPS Chartplotter or could still be out there somewhere! We pretty much did maps NR2, NR3 and NR4 in the dark.

The sart of the channel across Lake Cooroibah (the first, and smaller of the two lakes we crossed). Its a very narrow, very shallow channel - why do people fish in what is meant to be a boat passage. In no hurry to get out of the way either.

I left home in Townsville 6 weeks ago. Fished the McArthur R in the Northern Territory for Barramundi. Married off our younger son to a lovely young woman. Explored the Noosa R and the Noosa Everglades with Michael Glossie. Did a couple of days work in Longreach (the home of Qantas - google it!). Towed the BIG boat some 6,500 miles - that’s LA to NY and back, plus a bit! :!:

And now I am back home! :D

To put the distances BarraMan has covered these past six weeks in perspective, imagine hauling a big 20 footer on a loop from Florida to San Francisco to New York to Florida again. Bearing in mind that many of the roads in the far north of Australia are but partially sealed, the US trip is the easier one.

No wonder now that he's back home, he's kicking back and having a cold one or two.

Well done Lee! :D

Not sure what that says about the boat but it is one heck of a trailer test. I am pretty sure most of us will not trailer our boats that far during the entire time we have them.
As for the big Barra it sure seems to do every thing quite well. It is so nice to see a boat do what the builder hoped and for it to be used that way. I was sort of hoping for a Utube video of the BigBarra jumping waves on the Noosa bar :lol:

I have tried a couple of store-bought ice boxes in the hatch under the front deck of my boat, but nothing has worked to my liking. :doh:

So I have decided to put my newly developed glassing/epoxying skills to work to build a fit-for-purpose custom built ice box - or “esky” as we call them in Oz - “chilly-bin if you are a Kiwi (pronounced “chilly-bun”)! :lol:

Started on it today. Pics to follow when I have something to show.

Indeed Michael! My plan is for 2” (50 mm) high density closed cell foam all round, although I could be convinced to put 3” or 4” (75 mm or 100 mm) on the bottom.

50 mm foam will give me a 200L ice box. I certainly plan to provide good drainage, but I am still thinking through how to do that.

Glad to hear of your success getting Great Sandy over the Noosa bar.

I am using West System105 epoxy, 206 slow hardener and 501 white tint.

Image

I sanded the surfaces to be epoxied with 120 grit paper then rolled on tinted epoxy with a hard foam roller. I mixed the white tint into the epoxy until I had a nice "solid" white mixture.

Image

I expect to roll on 3-4 coats of tinted epoxy to get the desired deep colour and smooth finish.

Maybe I needed to sand more before tinting. But I also remember that even though I added more tint than recommended it was never 100% solid color, was always a little milky. Thanks for the step by step, I am taking notes!

Essentially fixed, but easily removed if desired.

Yes, I believe so, but Its being custom built to fit nicely in a large hatch under the front casting deck, so will not be exposed to sunlight. Being under cover should make it more efficient as well.

Lee, I've read through everything I could find about this build with regards to the scaling, but can't find any mention of how much extra material you needed compared to the standard BOM. Do you have a rough estimate? I'm guessing it was more than 10%...

Christer, increasing the dimensions by 10% will increase the area of panels, bulkheads etc by 21%.

So, at least 21% more ply, glass cloth, epoxy, paint etc!

The volume of the hull will increase by 33%, so you get quiet a lot of bang for your buck in terms of increased room, displacement etc!

Excellent, thanks a lot. While I still haven't decided on which boat to build, I need to know what I'm looking at if I should decide to scale my boat when the time comes.

Would you say it was worth it? Or put another way, if you were to build another Even Bigger Barra Boat, would you scale it again, even with the added cost?

Re: BarraMan's Mangusta 21 barraboat in Townsville, AUS

Posted: Sun Nov 25, 2018 8:20 pm
by BarraMan
Would you say it was worth it?
Christer, I think building your own boat is a personal thing. You go with a design that best fits a set of criteria that you have defined, but what works for one person may not work for another.

In my case, and I have told this story before, I have earned my living with my brain but have always been reasonably "handy". I have always wanted to build a boat and tell people who ask "What made you want to build a boat" that there was a boat in me that needed to get out.

The final triggers for me were:

1) that long-term desire to build a boat
2) a growing desire to chase barramundi in some of the more remote parts of northern Australia in safety and comfort
3) impending semi-retirement and the need to fill the looming "work" gap

I had never built a boat before starting on this one and I had never worked with epoxy before. Most boat building sites will say to build something small to feel your way into boat building and learn the required skills. I rejected that concept as I already had a smaller boat and decided that if I was going to build something it was going to be the boat I wanted.

Having looked far and wide, I finally settled on Jacques Mangusta 20 hull as the one that I though would best suit my mission - 18o deadrise at the transom, long enough to deal with the short frequency north Australian "chop", well powered and reasonable fast, strong and unsinkable.

Then I read somewhere that Jacques had said you could scale the plans up by 10%, and I thought "If I am going to do this I might as well build the boat as large as possible, and immediately moved to scaling it up by 10%. I really didn't consider the consequences of doing that in terms of increased building cost, issues with where I was going to be able to build it or house it afterwards, the need for a large tow vehicle or a higher specification boat trailer for it. My boat is right on the limit for what you can tow on the highways without a bunch of restrictions, signage and speed limits.

I just got stuck into building it!

Everything is at least 20% more than it would be if built as designed - materials, labour etc

I didn't even build the boat as designed. I built it as a side console with fore and aft casting decks - only the basic hull is "as designed".

The end result is a large, fast, comfortable, safe boat that can travel long distances (200+ nm range) and is a very stable platform for the lure casting type of fishing that I like to do. Where we fish, the boat is your life support system. If you end up in the water there a lots of critters that will eat you for breakfast, lunch or dinner!

Was it worth it? Absolutely! For me, at my time of life. I spared no cost in building it, and it is full of the best of everything in the way of "toys" (BIG o/board, sounders. chart plotters, trolling motor etc), but it cost me waaaay more than I would have imagined. If I was still trying to raise and educated my kids it may well have ended up yet another unfinished dream. I love it - as do my mates who have been fortunate enough to fish out of it.

I think this pic sums it up. Four of us are headed out some 50nm from our base camp for a days fishing, sitting on 26-28 kts. If you search for "Fat Fellows Creek, McArthur NT, Australia" in Google Earth you will see where we spent the day.

Image

Or put another way, if you were to build another Even Bigger Barra Boat, would you scale it again, even with the added cost?
If I was building for myself, yes - in a heart beat!

However, as I have said before, if I was 20 yrs younger I would seriously contemplate building this type of boat commercially. I would not scale it up and might actually scale it down by 10% because I think there is a bigger market for boats in that size range - lower build cost, smaller hp requirement, lower specification trailer requirement, lower spec tow vehicle requirement.

I worked out last night that I towed my boat some 12,000 miles in 2018, put 100 hrs on the motor and probably spent five times those hours on the water, on the electric trolling motor.

Man that is a lot of towing miles. With that much towing how is the new trailer holding up? I am sure the average here is less than 10% of your tow miles.

OQ, no tax deduction but as a self funded retiree I don’t pay any tax.

TW1, I have a Land Rover Discovery - great tow vehicle.

Image

Fuzz, the new trailer is great thanks. It makes the boat a very easy tow.

On a half decent road, you wouldn't know the boat was there - it just tags along. Unfortunately even Highway 1 in Queensland is only half decent in parts and once you get off the coast the roads are pretty rough from lots of heavy truck traffic. The new trailer is less "springy" than the old one (shown in the pic) and so rides much better. Four wheel electric over hydraulic brakes on the trailer mean that the Discovery and boat can probably stop in less distance than the Discovery by itself. I generally tow at 70 mph where it is legal and safe to do so.

Still armor. I mean it’s not plate, but then Kevlar is fabric and ar500 is plate. Most vests are Kevlar so I’m going with your trailer is armored.

April 5-14 is the next expedition to the McArthur R in the Northern Territory chasing Barramundi. This trip is special because my three favourite fishing companions are coming with me - younger son, ex pro-fisherman barra-nut mate, and a Townsville based barra guide mate. Two young young bucks and two old bulls! We have been looking forward to this since three of us first fished up there in Sept 2017. We have all fished the Hinchinbrook Channel with Knighty (the pro barra guide) before and we can't wait to share our NT fishing adventures with him!

Knighty and I are driving from Townsville and picking up The Young Bucks off the plane from Brisbane in Mount Isa on the way through.

A trip to the NT is like a Space Shuttle launch! The countdown has started.

I've been working my way through the Big Barra Boat from transom to bow tidying up my messy wiring and sorting out a few things that I have been unhappy with, and installed a salt and fresh water deck wash system.

The bilge.

Michael, I left the backing strips in place and just put a new rubber rub rail on it. To hopefully prevent it being “rolled” off by a big wave, I used a sealer/adhesive under the rubber strip in the bow section. Time will tell how successful it is.

Have you bought rub rail for “Skinny Dip” yet? If not I have a present for you - a half meter piece of black Radial 52 rub rail and backing strip so that you can see how it would look.

I've had a very bad day!

Posted: Thu Feb 21, 2019 2:06 am
by BarraMan
I've had a few issues with my boat. On my last fishing trip to the Northern Territory last year, I hit a rock in the middle of nowhere! One minute I was in 20' of water then "bang" I was in <2' of water, and by the time the boat came to a halt I was back in 20' of water. One of the locals said, "Yeah, there are a few unmarked pinnacles out there"! 8O

I was on the plane at the time but fortunately only doing 16 kts, not my more usual 26 kts.

The hit destroyed the skeg guard on the motor and took a piece out of the skeg. I later discovered that it also bent the propeller shaft slightly and bent the S/S propeller.

After Xmas I put the boat in for its annual service on the motor and decided to fully repair the damage - so new prop shaft, skeg repair, new skeg guard, prop repair and balance in addition to the normal service on the motor.

I took the lower unit (gear box and prop) to a repair shop that I last used many years ago. Imagine my surprise when it was the same shop, in the same place, with the same bloke behind the counter. I said to him, "I am an old customer - I was last here about 40 years ago"! These guys are craftsmen and repaired the damage good as new so you would not even know that it had happened. Then my marine dealership installed a new prop shaft and checked the gear box for any other damage. It came through with a clean slate!

Today I took the boat out for a water test - and maybe catch a barra or two. A couple of miles into a run up the beautiful Hinchinbrook Channel I noticed water slopping around on the floor of the cockpit. At first I thought it was just ice melt from one of my coolers but rather than drain into the bilge and disappear, it just got progressively worse. I stopped to investigate but couldn't find the source of the water, and confirmed that it was salt water not fresh ice water. What the @#$% !

About then one of my auto-bilge pumps kicked in a pumped large amounts of water out of the bilge. :help: I turned on the manual bilge pump and headed back to the boat ramp, pondering the possibility of a split hull! How can that be? There are 16 layers of 12 oz biax cloth across all the joins in the hull! Has the trailer somehow punched a hole in the bottom? I've heard of that happening with an ill-fitting trailer, but my expensive custom built trailer? No way!

Back to the boat ramp, pulled the boat out onto the trailer, climbed underneath looking for a split or hole in the hull - nothing!!!!

Hmmmmm???????? :doh:

So I figured I would go back home and fill the hull with water and see where it leaked. Packed the boat up, tied it down and headed for home thinking, "How can I get this thing repaired in the 6 weeks before we are due to go barra fishing in the Northern Territory again? If not, its gonna be crowded with four of us in my little 14" barra boat".

Driving along I decided to ring (hands free) a fishing buddy and tell him the bad news. As I dialed the number the cogs in my head clicked over, and the problem was solved !!!!!! What a relief !!!!! My hull is NOT split or holed !!!! :D

I have had a deck wash system sitting in the cupboard in my office for the last three years. A few weeks ago I decided to fit it to the boat. I got started - but not finished. What happens when you have a 3/4 pipe running from a water inlet under the hull to a from compartment where the deck-wash pump is to be housed - and its open at both ends? On the plane, water is forced into the inlet, along the pipe (although its located up under the gunwale) and out into the front compartment, where it then flows into the compartment drain holes and onto the floor of the cockpit, into the cockpit drains and down into the bilge.

It would have been smart to have a sea cock on that pipe! Oh, hang on a minute, I have one of those!

The moral of this story is, "If you are unexpectedly taking water - first step = close your sea-cocks"! :lol:

So here I am feeling greatly relieved - and a little stupid! :D

I thought you might find this video interesting!

This is my favourite barramundi fishing spot - the beautiful Hinchinbrook Channel in North Queensland, and this is what my boat looks like running up the boat passage at 40 kts.

In the first part of the video, where there are some ripples on the water you get some sensation of speed - but when I run onto the glassy water the boat appears to be almost stationary!

OK, so I am supposed to be retired, well, semi-retired at least, but for the past 6 mths I have been working on a large consultancy job and I am now in the late stages of completing the Final Report. Today I had a "rest" day and took a bit of a nostalgic trip down Mangusta memory lane by searching this site for other builds of the Mangusta hull.

There was a lot of interest in the Mangusta 20 when the plans first became available about 18 yrs ago (2002?). People asked about building it bigger (28'), smaller (14'), as a bow rider, and as a centre console.

However, although I can find evidence of at least a dozen people buying the plans, including at least 2 others in Australia in addition to me, I can only find photos of 2 completed builds - one as per the plans by fmiles

Image

and my much modified boat based on the Mangusta hull.

Image

Seems odd to me, because its a great hull. I have fishing mates who really know boats and are commercial skippers - they just love the thing!

The only challenge in building it is the scale - and with scale there is a cost, but the rewards are many! :D

So much for the day's contemplation! :lol:

Things went a bit crazy for me in 2019. I found myself on an aeroplane to somewhere at least twice a week for much of the year.
Corona virus has put a stop to that - my diary is pretty clear from now until at least September.

So when Covid-19 struck, I took the opportunity to put the boat/trailer up on hard stand and finish it.

SeaDek is going down on the decks and Kiwigrip on the cockpit floor.

As you can see, the SeaDek is light blue. The Kiwigrip is light grey.

In tropical Nth Queensland and the Northern Territory, the challenge is to keep things cool underfoot.

Yes, most unfortunate! I do have all the pics and will put them back in my build thread when I have some time.

I'll post some pics of the boat here shortly. Unfortunately I don't have any video of the boat up and going taken from another boat but I now have a drone and the next time I am on the water I will get some drone footage of the boat on the go. My drone is good for about 25 kts so it should be able to keep up!

Its taking me a while to sort out the idiosyncrasies of the drone! :doh: Its max.distance to fly from home base was set to 1 km - home base being the position of the front casting deck at the time of take-off!
So it followed the boat for 1 km, then stopped and hovered :help: - I had to go back for it! 8O
Just when I think I have the drone pretty well sorted, it does something unexpected - or won't do something that I think it should, like fly parallel to the target that its locked onto.
Can’t wait to see some pics of fish.
You'll be waiting a while to see some from me! 8O It was a bad day for fishing - very hot and quite windy. I found barra easily enough but they weren't interested in any of my lures even though they were feeding around the boat. I try to match my lure to what they are feeding on but it was what we call 'jelly prawns' (maybe tiny shrimp to you!), I had nothing to match that.

Was quite a difficult day for me. I lost a wheel off the boat trailer enroute to my fishing destination. I saw it depart in the rear view mirror. All five studs on the hub had sheared off! I would have said that I have never seen that before - but I have. Last year I stopped to help someone who had the same thing happen to his camper trailer. He blamed the alloy wheels which he said allowed the wheel nuts to loosen. I don't know! I checked them before leaving home - maybe I missed that wheel. We have had some issues with malicious tampering with wheel nuts in the past. I have towed that boat trailer more than 30,000 miles without issues like that!

Fortunately I carry two spare hubs with bearings, and two spare wheels - so I was able to do a roadside repair. I thought it interesting that only one person stopped to see if I needed help. I always stop to see if people are OK!

Sorry the fishing did not work out but as we all know it is called fishing and not catching.
About the trailer I too have lost the whole tire a couple of times. My truck is big and heavy enough I never felt a thing one of those times. I am going to try installing new wheel bearings every spring and see if that gets me through the season.

You went into detail how your system is hooked up and if I remember correctly, the outboard does not charge all 6 of those batteries. And, if I remember correctly again, you know how long you can troll before the trolling batteries need to be charged, shore powered charged? You are going to have to go into detail again. I am sure there are other gray-haired builders that don't remember the details either. :doh:
My OB has a 50 amp alternator (46 amps @ 1000 rpm).
The OB is connected to a 120 amp hr wet cell START battery.
I have a 240v AC - 12v DC smart charger connected to this battery.
I also have a 12v-12v DC smart charger between the START battery and the HOUSE batteries (2 x 120 amp hr AGMs in parallel).
I have a 12v DC - 32v DC smart charger between the HOUSE batteries and my TROLLING motor batteries (3 x 120 amp hr AGMs in series), with a master switch in between so that I can disconnect that circuit when the TROLLING motor batteries are being charged from mains power.
I have a 240v AC - 32v DC smart charger connected to the TROLLING motor batteries.

When on the shore I connect the two AC chargers to the mains power to keep everything charged and maintained on trickle charge.
When on the water the alternator charges the START battery, once that is fully charged the smart charger kicks in and charges the HOUSE batteries.
When they are fully charged the smart charger kicks in to charge the TROLLING motor batteries.

To date this system has worked well! We spend 80-90% of our time on the trolling motor with 3 x sounders/chartplotters running, and can fish for at least 3 days without needing additional charge. If things are getting a little low, I also carry a small gas powered generator/inverter with which I can top things up. At this stage I don't have solar top up!

Someone in another thread mentioned Sterling chargers. Just be wary - I have had three Sterling chargers fail on me, one while under warranty and two while not. I am now using Promariner mains chargers but I see Sterling have new model DC-DC chargers out.

I don't use voltage sensitive relays (VSRs) as I have seen or hear of 3 now that have burnt! Fire on a boat scares the hell out of me!

With 6 x batteries on board, I dream of lithium but the big $$$ involved in a change over keeps me at bay, at least until my AGMs pack it in!

Do you have an amp gauge connected to the outboard, to see what output it has to do after you have been trolling all day and the trolling motor batteries have been drained somewhat? Your smart chargers seem to also keep the OB charging system from "straining" and burning itself up all the time, correct?

PS: thank you for the details of how your system works.

Your C ratng for charging your batteries is typ 10% of AH rating or 24 amps.

The dc-dc charger in your system is rated for how many amps?

If you used half of the current available from your alternators; you'd be using about 24 amps. This is ideal.

For my boat, my alternators are 32 amps, my current C rating is 9 amps and the house is 24v. My dc-dc charger is 15amps at 24v or 30 amps at 12v. This means a low battery on the house will pull 100% of alternator output. And until I make the battery bank the right size, I would be charging above the 9 amp C rating. My bank is undersized due to a battery shortage. I bought two and planned to add two and now can't get the same ones, so have to buy four new ones $$$.

Your system sounds like it would tax the alternators much less, but still plenty.

What dc-dc charger are you using between the start and the house?

I looked at the ProMariner system and the one thing they have is an alternator temp sensor, which would be lotsa fun to route through my rigging, but is a step above the Victron Smart charger.

Unfortunately, ProMariner also charges at 40 amps in and 20 amps out for their 12-24 charger which means I could easily smoke the small alternators on my engines without using temp sensors.

What is the draft, top speed of your boat and with what horsepower engine? Considering building a Mangusta 20 modified to have a fishing layout with a single outboard, center console, leaning post, with front and rear casting decks and one of my goals is a top speed over 50 MPH. Primary use will be inshore fishing.

Primary use will be inshore fishing.
Keeping in mind that my boat is a Mangusta hull up-scaled by 10% and built with a side console and bass boat style front and rear casting decks.

1) I estimate its draft on the plane is about 18". I regularly run quite happily in 36", start to pay attention in 26", start to slow down in 24" and drop off the plane in 20". At rest can draw 18 - 24" depending on where the jack plate is positioned.

2) I have run my boat at just nudging 50 kts (58 mph) flat out! 8O It sits quite comfortably at that. It would go faster if I prop'd it for speed rather than power. :help: For me, 50 kts is FAST for a 22' boat. I am quite happy cruising at 30 kts, which seems to be a 'sweet spot'! I have yet to be overtaken by any other boat where I fish! :lol:

3) It has a Yamaha 250 Vmax SHO 4 stroke hanging on the back!

4) Jacques recommends 250 hp max on the Mangusta 20. I have no doubt that it would easily do 60 mph with 250 on the back. Having gained a lot of experience with my boat I know it would be happy with 300 hp - but to what point? :doh:

5) My boat handles very nicely and has no vices!

After 7 yrs in service and a conservative 55,000 km ( 34,000 miles) on the trailer, I climbed under the boat with a hammer last weekend to assess the state and security of the hull. 8O

The hull remains very sound! :D A few scratches and some rubs from the trailer (paint only), but a couple of spots towards the front of the keel where there are small rub spots down to the wooden core. :help:

Not a structural issue but I can’t leave the core exposed, so I have implemented a repair plan - an additional 6x layers of 12oz biax tape with staggered edges (2", 4", 6", 8", 10", 12") along the vulnerable part of the keel.

A 120 grit sanding disk on an angle grinder made quick work of removing paint and graphite down to bare glass, with the graphite layer a useful marker for sanding back to the glass.

Its awkward, but doable! I used an engine crane to lift the front of the boat so that I could get to the affected area.

Image

Now I am on to graphite, high-build priming, and painting!

Image

I had a Keel Guard on the boat when first built. At that time the boat was on a bunk trailer so the keel was not resting on anything. Unfortunately, one fishing trip to the remote north of Australia destroyed the torsion bar suspension on that trailer, so I had a new custom built trailer made with roller-rocker spring suspension. The builder convinced me to go with roller support for the boat. As that meant to Keel Guard would be sitting on a roller ladder, I removed it as they say not to use Keel Guard with rollers.

I now intend to fit Keel Guard to the boat again, but only run it to just before the keel touches to first roller - which should protect the vulnerable area. Where we fish mostly has a sand or mud bottom, so I think the damage occurred at the dam where we ski at Xmas time, which has a stony bottom. I will be more conscious of that in future. We'll see how it goes, in the meantime I am happy to have an additional 6x layers of glass between the external hull and the wood core. :D

3x coats of graphite/epoxy 1/3:2/3 by volume!

I'd rethink that keel guard idea. The FAQ for Keelshield says that if there's weight bearing rollers, even if just when loading or unloading that it can become an issue.

I glued an aluminium strip to mine. Just a bunnings 2mm by 30mm profile. Glued with gflex. On the sides I have UHMWPE flame treated then also glued with gflex. Both of which should be a lot more resistant to rollers than a Keelshield, at a fraction of the cost.

4 x coats of epoxy primer (sanded back somewhat)
2 x coats of 2 pack polyurethane under coat
2 x coats of 2 pack polyurethane top coat

The rubs are only 2 areas each about 2” long - so my repairs are probably overkill!

95% of the ‘at risk’ area now has 15 x layers of 12oz biax to get thru before the wood core is exposed! :D

Well, I have had two big “hits” with the boat on unknown rocks/pinnacles in the middle of nowhere, but they were taken by the skeg not the hull! :doh:

I guess I should have taken pics of the rubs, but they were only 2x spots about 2” long each, separated by 1x foot or so.

I have run aground unexpectedly many times but only on sand or mud!

My only explanation for the rubs is that they have happened over a number of years during our annual Xmas holidays when we spend a week or so waterskiing at a dam where the shoreline is stoney where I park the boat when launching and retrieving - no pontoon!

Some other rub areas down to the graphite only, but like you, I am surprised at the rubs through 9 layers of glass! 8O

My experience too, glass is not so resistant to rubbing. Waves impact, torsional forces yes, but for rubbing kevlar cloth will likely be more efficient.

In my case I am sure the skeg made noise as it departed but the sound of ripping and tearing glass drowned it out. :oops:

I've finished the repair to the keel rub. :D Will see how the Keel Guard fairs on my roller trailer! :doh: It is straight although it doesn't appear to be in the pic - just the angle!

Image

Seven years of accumulated Northern Territory red dirt on the trailer is pretty obvious. Maybe I'll get under there with the pressure washer. A job for winter 2024 - put the boat on hard stand and dress the bottom!

Next job for now - lift the motor off, install new house batteries and service a couple of pumps!

Why are you needing to pick the motor off?

Good question! :D

Under the rear casting deck I have:
Three batteries (Start and 2 x house)
Three pumps (for the 2 livewells plus 1x aerator
Three chargers (AC mains to 12v DC, 12v DC to 12v DC, 12v DC to 32v DC)
Four master switched
Two sea cocks

Its a bit crowded in there!

I can get at most of it from the front but its a bit of a hassle. I can't get at the two livewell pumps from there.

Fortunately I have a panel at the rear that I can access from the motor-well and remove.

I have an engine crane and a motor lift ring, so remove 4 x bolts and pull the motor out of the way without disconnecting anything is the easiest way to go. :D

I'll take some pics!

OK - so you were right! Keelguard needs to come off! :D

Just wondering, could you just use a shorter keelguard to protect the bow in front of the roller ?

So educate me some, what was wrong with the keel guard?

That's what I have done - cut it just ahead of the grey V in the pic above and removed all behind the cut. :D

I looked into keelguards; they all imply that any concentrated pressure will mess with the pressure adhesive. You could try this product, I've heard good things about it, and it can be replaced as needed without a full remove. Probably a heatgun is the only way to remove it anyway, sanding would be impossible. I rejected it in favor of that Aluminium strip.

Some NZ jetboaters use it apparently for when they can't or don't want to simply fasten 10mm UHMWPE plastic to the whole bottom.

Thanks for that - looks interesting! Unfortunately not available in Australia!

Carborundum is available commercially most places. You could try making some but it would probably be rougher than a glued strip. Or these guys will ship it to you. It’s a local company. Not the cheapest but all good stuff.

UHMWPE absolutely must be flame treated before you glue. And gflex is a must if using epoxy. Aluminium is a lot easier to manage but thinner, so you’re still going to get scratches on a beach. I did mine upside down so screwed it in till the glue set off. But with the thinner strip I used on the dinghy it held just by friction on the glue. No tape or screws.

I think I will just put myfaith in the 14 layers of external glass cloth that now cover the keel ! :D

Then just paint it with some if resistant epoxy filled with silica and pigment. Will be easier to touch up as you need it I guess?

The 'power station under the rear casting deck of my boat is a busy place!

........and tidy electrical work is NOT my strong suit! :D

I can access most of it from the front but I also have a hatch at the back if needed!

Its a long way down to the bottom of the bilge and the only way to access it without risking having to call the fire brigade for a rescue is to pull the motor aside!
