Yeah, I stumbled upon it yesterday. I had never heard of anybody going with vinyl flooring on a boat. I thought indoor outdoor carpet was my only option.
I requested two free samples - one white and one ivory. In retrospect, I wish I had gotten a sample of they gray instead of ivory. I talked with the owner of the site and he said to make sure the adhesive I use isn't too dark or it could show through the vinyl.
Before you order, have him send you a couple of samples to get an idea of what this stuff is like. You can probably hold something dark behind it to see if its going to show through.
Oh, by the way, I was worried about having to have a seam since the one I'm looking at only comes in 72" wide. Well, I went outside last night and measured the floor from gunwale to gunwale last night. Widest point was about 74" or 75", so I think I'll just have a little gap on each side rather than having to seam it.
