I have done 2 week trips in a C36 with a 32 gallon fuel tank and not needed to refuel. I motored some, and charged batts daily. Now with some solar panels, a lot less charging time, too. I would hate to carry fuel and water jugs on deck! I know it's probably more costly, but how about a bladder somewhere belowdecks, with a transfer pump? That is, a more permanent installation?
