We wrapped a bass boat 2+ years ago with 3951RA and 290G lam. We sealed the edges with a 1/2" strip of lam. I am very good friends with the guy who owns the business that primarily sponsors the boat and the actual owner of the boat. It is still holding up well, the owner told me that the only problems he has had are damage that he caused by hitting the dock. My personal boat is wrapped with 3551RA and has been for also about 2 1/2 years and is fine. It is a pontoon, so the wrap is not in the water but the boat sits in an uncovered slip during the entire boating season.
Also, I'd like to see somebody install a bass boat with non-air-egress vinyl (and the final product). I'm not saying it can't be done, but I imagine the time would be doubled and the results cut in half.
