The deck (floor) of your boat is part of the structural system that connects the stringers ('floor joists') to the hull along it's edges.
You probably need to do some demo, or at least in depth sampling, of the below deck foam & transom to confirm they do or don't also need to be replaced. Based on your pix it could go either way:
I'm not sure how you'd accomplish that if you used an aluminum deck.
Since it's an aluminum boat, any stringers or bulkheads that work w/ your new layout, can be reused.
I have an 18' Crestliner Super Hawk that I'm replacing all the deck plywood while changing to a vinyl interior. The original 1/2" pressure treated plywood is in good condition, but thinking of replacing it with 5/8" or 3/4" since there are a few broken out places because of thin cuts. Is 3/4 to thick and heavy for decking?
For what it's worth, the original deck in my boat was untreated 1/2" plywood covered in vinyl. It was black sawdust when I got the boat - I used the shop vac to get it out. I wouldn't ever use non-treated wood in a boat.
Last year I picked up a few sheets of 1/2" ACX 5 ply plywood, but it's no longer stocked at the big boxes, go figure. Lowes sells Arauco plywood that has thin plys, bonded with exterior glue, is pretty rigid, supposed to be void free and has a nice face veneer, so it seems like it would work well for a boat deck. One thing that is odd, even though they say it's suitable for exterior applications it does not have an ACX rating? What do you think of Arauco plywood for boats? Should I look for ACX elsewhere or spend the cash and go pressure treated?
