the deeper I get into this build the deeper I realize I need to go. I was looking through other builds for ideas,which I ve gotten plent of thanks to this awesome site.I pulled up my flooring after reading about waterlogged foam and found waterlogged foam of my own not to mention rotted plywood under the rear deck.Ive used the pvc board in the past on another project and it worked well. Im gonna use it on the back deck,every thing else will be decked in aluminum. I now have every thing stripped out down to the basic hull so now i am only limited by my imagination and my wallet. pics coming soon
