How much fuel should I carry if I want to be assured of motoring (in
case there's no wind) non stop for 100 miles? 30' boat, disp.
#7,500. Yanmar 2GM20. I have a 12 gallon tank.
TIA

I have done 75 miles using about 7 European gallons on flat calm. US
gallons are about 10% smaller.


Your tank should be big enough, but I'd carry a couple of extra gallons just
in case.
