plywood deck, balsa then fiberglass?

2 posts in this topic

Hi, I have a 1976 Aries 32. Traditional attachment of 1/2 inch plywood deck to a fiberglass hull. Plywood is exposed underneath and sits on a framework fiberglass over top the ply.

The deck needs replaced.

Would it be possible to lay 1/4 marine ply on the framework then bond 3/8 balsa to that plywood ( what is the best way to bond; vacuum bag or gravity weight like bricks, etc. the balsa. Does 1/4 ply have enough strength to support the gravity weight without making depressions ) then fiberglass over the balsa?

Or would it be best to stick with 1/2 inch marine ply and glass, like the original, as a replacement?

I do realize there will be some difference in height with the balsa but that can be easily addressed.

I would go with 1/2 marine plywood, sealed with a penetrating epoxy sealer on all surfaces, then fiberglass cloth.  That would be the original, the balsa option would save some weight but be more work to put together.
