Treated plywood deck and alum boats-Don't do it!

[kydonky]

I don't mean to hijack this thread, just wanted to make
everyone aware that there's a product available called Nautolex that is all vinyl and can be used instead of marine carpeting. It glues on just like carpet and is very easy to work with. Cost is comparable to carpet and you don't have to worry about hooks getting caught in it. It has a textured finish and is very easy to keep clean - just hose it off! I found mine online - don't remember the name of the outfit but they were in Florida and there's a dealer in the Carolinas somewhere. It's also available at The Wooden Boat Shop in Cincinnati. I installed it over 3/4" marine ply 3 years ago in my '84 Tracker and absolutely love it!

There is also a product out there that is called duraboard (I think that is the name of it). It is a poly resin material similar to the trex decking material. It can be worked (cut, screwed, nailed) just like plywood, but will not rot, warp, mold or get eaten by ants. Bad news is that it is very $$$$$ about $150.00 per 4x8 sheet (last time I looked at it). Even with the cost it may be an alternative as marine plywood is also veryy $$$$.

The other plus is that it is much lighter than treated or marine plywood. You may loose 100-200 lbs of weight depending on how much you use. Resulting in better gas economy, higher speed (use a high pitch prop).

Has anyone used any of the trex decking material in a boat out there? I would think that stuff would be perfect for a boat application. I think they even make support pieces now.
