Please do a search on this board for pressure treated plywood and aluminum or google pressure treated plywood galvanic corrosion or something like that. The wood asociation does not even recommend putting today's treated wood on contact with amuminum siding on a house-- it contains less arsenic and a lot more copper since 2006. Copper + aluminum + water = electrical charge that eats holes in aluminum pretty quick. I would not get today's pressure treated wood of any sort any where close to a an aluminum boat including carpet trailer bunks. I presume your boat is aluminum?

I would look into some of that vynil flooring that looks like carpet that they are using in some of the newer boats as well..
