Re: C17 open 'Fair Enough' in France

Post by OlivierP »

Looking at the profile after gluing the side panels, it seems that I have some droop at the bow. Maybe the thicker panels did not bend exactly as expected. I'll probably try to pull the bow back to see if it helps before installing the rub rails, or add a spreader close to the bow, otherwise the droop may become permanent. Not a deal breaker but I'd rather avoid it. Any advice welcome. Thanks

Not sure what you are referring to since I see that you have all the panels filleted and laminated. Please provide some pictures for reference if you can.
thanks,

Thanks, I'll take a picture when I go back to the workshop, likely Saturday. Everything is glued, but the tip of the bow droops (actually lifts, since it's upside down...) by a few centimeters when seen from the side. Maybe the panels aren't spread enough towards the front, between the bow and frame A. You can't see that from the current pictures.

This pops up a lot in the C series boats. 17, 19 and 21.

I wasn’t partial to the look and flattened it out after the flip, before sticking the deck on top of the frames. Shaving out the hump left some skinny sections of rub rail, but I was able to fill these to a batten which made it all go away.

Regrettably, I didn’t correct it where it shows on the bottom edge of the upper panel. Maybe next winter.

Point being, it’s there, but you can make it go away.

Like Dan said this really happens a lot if you do not pay attention and pull the panels down hard when stitching. Follow his lead and you can fix it.

Found a pic of the correction. From October 2021.

I discovered mine after flipping, and the rubrail was on.

I glued the backing block for the cleat on top rather than under the front panel. This somewhat hides the droop. I may eventually bolt a bow roller on it.

Thanks to all, it's about similar to what Dan shows. I'll probably fix what remains after the flip the same way.

I think I'll pre-cut some extension pieces for under the last meter or 2 of the rub rail at the front, before mounting the rail, to be ready to extend it if I have to cut it down. It also means that I won't paint the sides before the flip as I initially planned, probably only the bottom and maybe the lower side panels

This is the droop at the bow

9872

I've pre-cut rub rail extensions to fix it after the flip.

9871

Otherwise, installed the keel and built dams to sharpen the edges of the last 2 meters of the sides and the transom

9870

And busy glassing the console

Just remember after sharpening the edges you will need to round them slightly say a 1/16" - 1/8" so the paint will hold. It can create a crack on a sharp corner. Tom
