I did my entire boat with marine grade plywood. The Deck with ½ “ and the transom with 2 sheets of ¾”. If I had to do it all over with again I would do things differently. On the transom I would use a composite material and with the deck I would use plywood where the sheet metal screws attach the center consol and the leaning post seat but for the rest of the deck I would use composite materials. When I did my boat the composite materials were being used, but there was not enough years of use on the new boats to influence me from using the traditional materials of marine grade plywood. Usually it takes 5-10 years of use to really know or not if it really works. As for this new type of plywood with paper laminations in it. I personally would not use it due to the possibility of delamination. For me when in doubt either go with what is tried and proven or go one step up in quality.
