Yeah, MJ, ...you can call me "Foamless in SC"... :-/...

Re: polyurethane foam
 

The floatation standards have changed in the years but I thought that atleast the "swamped floatation" standard would have applied to all V-20s built. Today a V-20 would have to conform to the "level Floatation" standard. My 1972 V -17 had foam in it.
Below is a link to the boatbuilders floatation standards

Re: polyurethane foam
 

I think the ''sinks like a stone" standard applied to mine...I'd be pleasantly shocked (mostly shocked :o ) to find ANY foam flotation in mine...last foam that was in my boat "Mullet-Head Walker fumbled a cold PBR on the deck jumpin' for a well-bent striper rod... 8)...

Surprisingly, the foam was is good shape, however the same is not true for the stringer and floor supports (members that run perpendicular to the stringers). What originally were active cores of 5/8” plywood is now foul smelling decomposed muck in a casing of fiberglass being held in place mostly by the foam, so badly deteriorated that injecting epoxy would not repair them. Two center floor supports were cut off today leaving about an inch of the fiberglass skin in all three sides to provide for an exact replacement location, cleaned and ready for new plywood tomorrow. Although I was surprised as to how sturdy and well built the stringers and floors are, Wellcraft forgot to seal (caulk or epoxy) around the plywood edge in the areas that had been cut out for cable sleeves and drain. I’m taking pictures and I will be sharing them soon.

FL they didn't forget they just didn't do it lot of guys here opened up their boats for the same reason and found the same thing

Re: polyurethane foam
 

Lots of guys w/ mfgrs other than Wellcraft, too...saw a Grady on THT the same way... ;)...

What's the stuff to pour a transom?...couldn't you pour stringers/cross-members as well?...just cut off the tops, clean out rot, pour and glass-over again...seems reasonable to me...it'd sure never rot again ;)...

Seacast

Re: polyurethane foam
