lgdpt,
To each their own, however what would seem most logical to me is not to spend a lot of time and or money constructing something that might leak or not be safe in the event of a mishap or collision when marine approved fuel tanks that will fit under the seat of a 13 foot sport go for $25-$75 depending on size. I would believe what you will spend on materials will exceed that and I know for sure that the aggravation quotient will. From the looks of the sport on your personal page, I think your time and money will be better spent on restoring other parts of the boat. After all, after reinventing the wheel in the form of a custom fuel tank, that is what you will have. Just another wheel.
