have been reading some post on here, I was going to buy marine ply to make a floor for my half cabin boat as factory is doesn't have one, and upon reading I was surprised to see (if I understood it correctly) that normal ply can be used as long as it is epoxy coated on both sides. I was also in shock at the price my local hardware shop was asking for a small piece of marine ply when id need 3 pieces totaling $440 dollars, or are there any other materials that i can use to make a floor as I want a flat even surface to carpet and for my children to walk on with ease
