I went and looked at a boat for sale today. A 1979 Rival. I really liked the boat and the way it was set-up. The only negative thing was that it had blisters below the water line. The largest were 2 inches in diameter. I read this from a survey 4 years ago. I know some say that blisters are mostly cosmetic and not much to worry about. Especially on a boat that old. What worries me is resale. This boat has been for sale for about a year. Other than that I really like the boat. It's prob the most boat for the money for a 34 footer that I've seen in awhile. What do you guys think about blisters? Thanks.
