Answers:
I agree with the guy who said masonite. You can go over plywood, but if you make your framing members close enough you do not have to. Plywood is more difficult to bend.
use masonite over a plywood base and change it frequently. It's nice and cheap...
extera plywood is what you need then after applying it you need to water proof it with deck sealer
If you really have the money, go for marine grade plywood. Costs about 3-5 times more but the glue is designed to hold up under wet conditions.
