Are you going to keep it stowed?
Jim:If you are going to keep it stowed when not in use, a PVC unit like the Zodiac or West Marine units may serve you well. If you want to leave it inflated and in the sun I would recommend a hypalon unit (Avon, Achilles, AB, Caribe etc). I may also suggest that you get one with an inflatable floor rather than plywood. These plywood floor are a SOB to install. Installing them on deck would make it even worse.A couple of things to look out for. If you have a dog and need a dink to ferry them to shore, PVC is not very forgiving. Also you need to be careful with any fuel spills on PVC it can degrade the fabric quickly. The sun is NOT PVC's best friend. I had Quick Silver units and they replaced 3 of the hulls in about 3 years. Finally sold it and got a Hypalon unit and have never looked back. I know several people that have had good luck with PVC, but I was not one of them.
