[QUOTE="thill, post: 495879, member: 4972"] I decided to pull out the floor of the 1996 Spectre 16 sport. The wood was still solid, but is really waterlogged. Super heavy. I figured that the foam underneath it would be completely soaked too. When I pulled up the flooring, I was surprised to see house-wrap underneath it. Huh??? Pulled back the wrap, and surprise-surprise, the floatation foam beneath was dry, and the aluminum stringers look super shiny and new. Shocker!! Looking at the carpet and rivet pattern, I'm pretty sure this is the original floor, so this must be a boat builder thing, but I've never seen this used before., and I've pulled a lot of boats apart. House wrap is supposed to be waterproof, yet it allows water vapor to pass through. Has anyone else ever seen this used under a floor? I like what I'm seeing! A simple concept that seems like it wouldn't work, but there is the proof. I'm thinking about putting fresh Tyvek under the new floor, and I might be using this in the future. I LIKE having nice, dry foam in my boat. In this case, it saved me a LOT of extra time and money not having to dig out the old foam and replace. Let me know if you have any thoughts on this. [/QUOTE]
