Do I need to seal the marine grade plywood? It's my understanding that marine grade plywood is not treated with any chemicals to reduced rot/decay.
I'd consider the standard grade plywood if I need to seal either way.
I redid the casting decks on two of my previous boats and each time I used a 4-5 ply ½”CDX fir plywood (NOT PINE!) that I just painted after cutting out the different shapes. Obviously the stuff is less expensive, it's also lighter, and after painting and carpet should hold up for the life of the boat provided you're not leaving it exposed to the elements.
Keep in mind this is not a floor, it's a raised casting deck that will probably be undercover for most of his life anyway. Good luck!
