I agree that gas if a far inferior fuel
. It is much more volatile, has a shorter shelf life and is more likely to have quality issues than diesel.
Diesel is used in every industrial vehicle that requires power. Tractor trailers, busses, locomotives, commercial
aircraft and large marine
vessels. All of these applications are torque based engines. Torque output of the engine is what moves heavy loads and diesel engines in general have a much better torque curve than a comparable gasoline.
Sailboats require more torque than hp to move. A low hp high torque engine will turn your alternator
, push the boat and have power to spare.
In a jam you can put just about anything that resembles diesel in your engine to keep moving, try that in a gasoline engine. Plain and simple diesel is just better. No question....
