I am the second owner of a 2010 Triumph. The original owner only had it a couple of months before selling it to buy a larger boat. The Triumph had bottom paint that the dealer applied. I used the boat in salt water in Boston this year and now the bottom paint is gone! The dealer swears the bottom was properly prepared before it was painted, but who knows. I am asking for a recommendation for a good bottom paint to use that will last the season (or more) with the boat in salt water eight months and on the trailer four months.
