I currently own a 18 'bowrider . am thinkin i would like a 24' cruiser and do some campin . but im a little concerned about fuel in a boat so large . i only cruise at moderate speeds with my 3 liter , but a 5liter might be more than double i guess ? or is there a better motor and drive more fuel efficient?
I have a friend with a 26 foot searay that is only a few years old. It is powered by a single 350 ci engine and at hull speed, about 5 knots, he burns 3 gph, at 20 knots, 14 gph.
