Tom, the trouble with using gallons per hour is that it doesn't measure
fuel economy. If I burn twice the gallons per hour, but go three times
as fast, then burning at the higher rate yields greater economy.

I will grant that if you are comparing identical boats at identical
speeds then gallons per hour would give the desired result.

BS

The reason we measure boats in gallons per hour and not miles per
hour? Wind and current make miles per hour impractical. With the
current against you, the engine can be running at 6000 RPM for an hour
and you have only covered two miles. I have seen that in the Inside
Passage around the Fraiser River. Too big of a veriable there. RPM's
and fuel used can be realistically monitored.
