Re: questions on foam under floor?
I bought 1 inch sheet insulating foam, Home Depot, the white closed bead stuff doesn't hold water like open cell foam does. Use a "keyhole" thin pointy saw to shape the foam to stack in fairly snug. Keep it in place with spray plastic foam like they use behind electrical outlets, it swells up and locks the sheets in place. Once that sets up, you can reinstall the floor boards.
I make "access ports" on the floor board centerline so I can access the keel area, with wood bulkheads to contain foam, and I get extra paddle, rods, or ?? storage too.
I'm not in love with the liquid two part mix and "watch it grow" foam mixes. I like to be able to remove the sheets if I damage the bottom somehow, or check for water if the floorboard comes unstuck.
Just a thought, if you are redoing the floor boards -- get the (poison kills mould) cheapest anti freeze, mop it on the wood, both sides, after fitting and before epoxying in place -- let it set 4-5 days till fully dry -- then epoxy in place, no more floorboard rot, and f'glass bonds to the ply just as well, maybe better.
No rot, that's hot !! Good Luck, Cal
