My boat doctor, in whom I have a reasonable level of trust, mentioned today that he knew of two Tomcat boats in southeast Alaska that are having to have fuel tank replacements due to moisture trapped between the aluminum tank and the fiberglass hull below. For some reason I thought the Tomcat was manufactured with the tanks supported on blocks of starboard or some other material to ensure there is an airspace between the hull and tank. I just doublechecked mine and there is no gap. Southeast Alaska is a pretty wet place. Is premature aluminum tank deterioration an issue in Tomcats? Mine is a 2007 that I bought new. :crook
