			If you're not going for true marine grade plywood, which has no voids and made with waterproof glue, the ACX is the closest thing...but it has voids in it which can be a long term problem.....you can buy 3/4 inch XL marine ply from Boat Builder Central for like $60+....Meranti type high end stuff is over $100...even a good quality ACX is close to $40, if you can find a good quality panel.....is the 20 or 30 buck difference from a true marine ply worth it when you look at the entire scope of the project? I agree with what was mentioned above....stay away from engineered building materials like OSB or LAM...good for houses...not for boats
