I know most have suggested marine plywood for decking on this boat. I have not been able to locate Marine plywood within 200 mile of my house. I can get Aluminum 60 miles away. Do you think smooth 3/16 or 1/4 3003-H14 aluminum would work?
I would go with good exterior plywood before aluminum. The only real difference in marine plywood vs exterior is that all the voids are filled in marine grade. You can add some extra sealer if you want. One other thing that I would emphasize is to use stainless fasteners for anything you put in the boat. It may not seem important at the time, but it is.
