Re-decking

[Robfree]

What do you think about hoop pine F17 grade marine ply for yacht deck 37ft

[Cheechako]

No ply as deck. You mean underdecking?

You should take a look at this stuff if you're planning on using ply as core or a substrate. We've been using it to replace ply in deck core for years now, it's awesome. Just doesn't hold a screw well, if your planning on fastening to it. Glass bonds to it much better than wood and of course it will never rot.

MDO, same stuff the highway dept. uses to make signs. any lumber yard can get it for you. Not pricey, 1/2" about 35.00/sheet, 3/4" about $47.00. Can't imagine a better material for re-decking. I have it on my boat.
