Re: How important is fuel capacity?
FWIW, our internal diesel tank holds 20g and for longer trips we carry 10-12g in jerry jugs carried internally. If it isnít possible to sail (light/no winds or light winds on the nose, we would motor if we need to be somewhere. Our longest motor trip was Annapolis to Mystic (via C&D and Cape May canals and outside Long Island) for a total distance of 320 nm. We used perhaps 25g of diesel for that distance, which included a fuel stop at Cape May and transfer of 5g at sea (to keep the tank at 1/2 or more. We ran our 3GM30 at about 2200 rpm and averaged about 13 nm/g. The longest continuous motoring was about 36 hoursólove that diesel!
