Marine grade lumber

Probably another thread on this, but I couldn't find it...

Any idea where I can find a couple marine grade 2x4s?   Looking to replace my bunks.   

Related question, do I need marine grade 2x4's for this?

Related, related question, do marine grade 2x4's even exist?

How about Trex, or one of the other composite deck materials?

Or,

Since the bunks don't typically spend a lot of time wet, why wouldn't regular wood work?  Or treated wood? (watch for corrosion issues)

I just use treated on trailer and boat lift bunks.

I don't believe theres such a thing as marine grade lumber.  Marine grade plywood is merely a void free product with exterior resins and glues.  If you wanted as close to a marine grade lumber it would be white oak.  It weighs 5-6 pounds a board foot vs less than 2 pounds for untreated 2x4 SPF

Just use treated, we have treated 2x8's on our boat lift and they are wet and dry constantly and been on for ten years.  Only reason they could use replacing is from bashing into the fronts of them with pontoon some times.

That's only because the water up by Cass is so sterile and devoid of life not even mold or rot can grow!
