Hi Chris.
My "Putz style" hit the water this past week with no ill effect.
It is skinned in 3.7 oz aircraft dacron (Ceconite - it cost $72.00 Canadian
for more than enough to do the whole craft). The dacron was surprisingly
easy to work with, almost no wrinkles at all, even before heat-shrinking.
Small puckers at the top longitudinal seam make it look kinda authentic
(IMHO)
I coated it with Flecto Outdoor Diamond Finish. The 3.79 litre tin
('merican gallon) was $60.00, and is enough to do 2 more 'yaks.
The finish is water-based, and not designed for below the waterline, but I
tested the stuff for several days submerged until I actually used it. I put
on 5 coats (paranoia?), and it went well.
The only toxicity issue I had is that I made my coaming out of ABS, and the
solvent cement for it is deadly. I don't think I'll do it that way again,
although it looks "bought".
