Is Marine plywood a must?
I need to build a small shelf for an additional battery. My existing batter boxes are molded in fiberglass, in the lazarette, and stepped up the angled hull. I’ve made a template with curved bottom supports add a plan to screw in the sides of the existing battery “trays”. I need to make this in a couple pieces, then screw it into place, so that its secure, and strapped.
Marine plywood would be my default choice, however its hard to find where I am, and expensive to ship. This area of the boat is never wet. I’m considering just getting some A grade plywood, birch or something like that, and coating the pieces with bilge paint. If there are any voids in the laminate edges, I’ll fill them with epoxy or something.
Does this sound reasonable or should I really try and find some “marine” plywood? It needs to last.
