Wanted: Marine Plywood

[BearLakeFishGuy]

I have used "marine" plywood and it is a lot different than regular 3/4 outdoor plywood. In regular plywood (3/4") there are about 7-9 layers. In the same thickness of marine plywood there are about 17-20 layers. Also, in marine plywood there are no "voids" as in regular plywood. Just look at a cut end and you'll see what I mean by voids. What Jim did is the next best thing, but for the cost of epoxy, floor coating, and my time waiting for things to dry, etc. I went with marine plywood in my old boat and it worked great and was worth the cost. I paid about $70+ per 4x8' sheet. I just painted over it to match the rest of the boat with exterior paint. Overall the marine plywood is much stronger than exterior plywood and is treated to be in contact with water not just in "damp" areas like exterior plywood.. I replaced the transom in my old boat so I wanted to make it as strong as new. Just my $0.02 worth but if I go with flooring in a boat I'm using marine plywood since I don't have the time/patience it takes to treat the other plywood with epoxy resin.
