[C320-list] Subfloor for cabin sole

[bruceheyman]

I would use a product like hydrotek marine plywood.  It will be made only with hardwoods and will have no voids, even in interior layers.  It will also have more layers, probably 13.  I also recommend that you seal the underside with a couple of coats of Smith penetrating epoxy for even more moisture protection. Bruce Heyman(949) 289 8400

I’m going to replace my subflooring with 3/4 plywood.Here’s my question: What sort of plywood is considered acceptable in this application? I know that I need a smooth-surface plywood, but beyond that, what should I look for for in a plywood? Home Depot doesn’t list any plywoods as ‘marine grade’, and just about the only feature they list is pressure-treated. As a result, I’m a bit at sea on this, and any advice would be helpful and appreciated.--David VeenemanSV Adelante, Hull #131Dana Point, CA
