I looked at the 46.3 for a possible purchase and the 53 gallon fuel tank plus the small water tank was a issue I did not like. If you run the generator 12 hours a day you will burn 6 to 7 gallons each night. That leaves a 53 gallon tank barely adequate for a 7 night charter. Anything more or if you motor a lot you will need a fuel stop. My old Beneteau 50 had a 106 gallon fuel tank and 300 gallons of water in comparison.
