we used very little fuel, and topped it off when we returned to Conch.....8 gals in two weeks.

We should have topped it off at a fuel dock that was not associated with a charter company.. They had their own fuel pump and dock.

Erica thinks it was around $ 4.00 per gallon.

If we were filling the tank of a catamaran , or used a lot of fuel in a mono hull, that would have been a good chunk of change.

Lesson learned.
