Floor Support ?

[yama]

Hi there ppl.
I'm busy rebuilding my boat and i need some advise. I had to remove the whole floor and now i need to redo everything. What kanda support do I need to use for the floor. And what type of ply wood should I use.

Thanks

No idea about what kind of boat you have so I can?t suggest anything about supports. Best idea is replace what was there.
Marine plywood is stronger, has waterproof glue, and will last longer than lumber yard plywood.

Marine plywood is a good choice but if cost is a issue there is ACX plywood as far as I know the main difference between the two is that marine plywood has all the knot holes filled where ACX does not. They both use an exterior grade of glue. Here in N. California marine ply sells for about $80-90 a sheet ACX is only about $30-40 If you were redoing the bottom of your boat marine would be the only way to go. Hope this helps!

One small correction; Real marine plywood has no knot holes, filled or otherwise.
