imported marine ply/laminate made in Netherlands, nice stuff, I couldn't of afforded it unless I worked in the biz.....what I found really interesting was that I used two full 4 X 8 sheets, well almost all of it and I only have a 32 foot boat.....didn't think there was that much room below.....now it looks like a dance floor!
