I had a debate with a friend this morning concerning miles vs gallons
per hour.

I contend that gallons per hour is a more reliable method of
determining how far and fast a boat can/should go. Obviously, my
friend took the opposite viewpoint.

What is the collective wisdom concerning these measure of fuel
efficiency?

Later,

Gallons per hour can determine work output only. If you rope
the boat to the dock, and burn 20 gallons per hour, what does
your numbers say about that?
