molded-in fiberglass tanks... even some high end offshore boats were as
So to add insult to injury, the fuel system gets clogged and the tanks fail,
leaving the ethanol to attack the hull, too. The Wall St. Journal had an
article recently about marine insurance (fake) claims and abandonment of
boats are both on the rise. Presumably because of the economy. I suspect
Ethanol might have a part in it, too. It might be far cheaper to scrap a

holes in the bottom.
My older 34 foot Sea Ray has aluminum tanks, fortunately. =)
