Good luck. PT plywood is a miserable material in my book. The minute the
bands are cut on a lift it starts to warp. The second a sheet is
separated from the lift, it warps more, faster.

To keep it from warping it needs to be nailed off at least as tightly as
in residential construction i.e. at 16" on center. into 2x4's.

For my 2 cents, any project on a boat involves enough effort to buy a
better material.

Use MDO if you don't want to spring for a marine ply (i use MDO in lots
of places that get painted on my boat(s).

Has anyone had any experience using pressure treated plywood for a marine

covered with vinyl) and I wondered if this product would do the job.

Thanks in advance
