Using Trex boards as sub floor.

[OLDDestin]

The floor in the cabin of my 1983 Trophy has a few soft spots. Since it is covered by carpet, I am thinking of ripping out the floor and replacing it with Trex decking boards which is readily available and totally water-proof, not to mentioned easier to handle than plywood sheets. Has anyone tried this before? See any flaws in this plan?
Thanks

IMO Trex is not structural. It has little strength and is heavier compared to wood.

The original floor lasted 28 years.

Don't mess with something that works.

My thoughts exactly.

Trex is ungodly heavy, not to mention all the issues people have with it on decks when it gets damp and wet, why would one want to put in in a boat?

3/4" PT plywood. Lighter, structural, cheaper than Trex and made for the application.

I would consider Starboard before trex. Problem with plastics though, they need room to stretch and contract as weather changes. Plywood is probably your best bet.

if there were a better product for that application fine yacht builders would be using it already.

Yup!

If PT is too much $$, seal all sides and edges before you glass it in.

You may want to consider marine plywood. The pt in plywood is for insect control and doesn't give it any rot resistance.

PT rated for Ground Contact is rot resistant. I've got PT 4x4 posts buried in the ground for over 20 years now.

Thanks everyone for your comments. Sounded like a good idea at the time. I guess plywood it will be.
