So the other day I picked up a lil toy. A 70's era Folbot Sporty. 15' by 32" . When I picked it up it was flat as a pancake. All the plywood frames had delaminated. So last night I started to tear into her. I pulled all the hardware off and stripped the material off the deck. This evening I started doing a little bracing and measure-ing and started to fabricate new frames.
5 more to build...
Thanks DGentry for all your advice!
I will hollow them out after final fitting, then coat it all with epoxy and then recover the deck and paddle the lagoon.
