    I have a re-do going on...trying to think this out without over thinking it...

    Cutting out the benches....adding bulkheads, and decks...

    Looking at Marine Grade plywood, or similar.

    What thickness do I need for the bulkheads & dividers?

    how about the decks?

    I was thinking 3/8 for the bulkheads, and 1/2 for the decks...but I don't want to over or under shoot this...I want the least weight possible with those materials, but not sacrificing stability and strength

    !/4 inch marine ply will work fine for bulkheads.
    Can be used for decking also if cambered and
    a layer of 6 oz tooling cloth applied to each side
    over proper framing.

    Yeah I chickened out and got 1/2-inch. Well, my deck will be overbuilt. Try Brett's method of bending the deck in a slight frown shape to resist moment forces. That may be the "camber" he's referring to.

    Brett, you used luaun too, right? That stuff's pretty well priced.

    1/4 inch water resistant luan, sealed with epoxy and fiberglass, both sides.
