Macca,
How did you fixed that stanley steel ?
Like I see on the pic it's in one part, but how thick is it ?

TW28
"skeg
n. short fin, projection or brace at rear of keel of a sailing boat; fin at rear of surfboard."
You are right Jacques it is not a skeg but technicaly it's not a shoe either as it doesn't have sides. It's a 3mm 316 marine grade stainless steel plate adhered to the keel using Sika Sikaflex-292. http://www.sika.com.au/cmi/marine_products.htm
Why?
1. The marine surveyer suggested a shoe for protection when the TW28 is on a hardstand. I didn't want to compromise the keel lines so we settled on a 3mm 316 marine grade stainless steel plate. As he is the bloke who signs off on the survey certificate I like to stay on his good side.
2. Moreton Bay, where I intend to spend a lot of my time, is shallow in most parts and has shifting sand and mud banks. The 3mm 316 marine grade stainless steel plate should offer a little more protection when I find one.
3. The study plans state "This hull is designed to have around 2,000 lbs of ballast, some of it is trim ballast." The 3mm 316 marine grade stainless steel plate weighs in around 110lbs. Extra weight in the keel will help to cut down on ballast.

Macca,
The paint has really helped to define it, it's looking great, even with the current stargazing keel. Of all of it, rolling to upright is the part that will also have me the most concerned. Enough prep, and it should behave predictably, all good. I'd help if I were in the AU neighborhood. Great job again, you're moving along at a good pace, just curious, is it just you, or, do you have others to help on occasion?
Cheers-

Thats why I was curious about his use of a very expensive peice of stainless plate for his skeg when he could have used Iron or concrete like most production sailboats do? Any Ideas on Concrete?
But, oxidation is not the only cause of corosion how bout Electrolosys.
Sorry terrible speller

SS will have excellent resistance to abrasion and this builder may have had access to inexpensive SS.
In most cases extra layers of glass are the best way to go but this keel already covred, on the outside, with 3/4" fiberglass!!
That's as much as I had on my sailing SUV (my last big sailboat) and I crushed my share of reefs with it.
