Does anybody know what relation there is between fuel consumption of a
displacement hull and its speed?
Is this linear, quadratic or something else? To make it more concrete,
say you have a consumption of 60l/h at cruising speed. Would you then
e.g. see 30l/h at half the cruising speed and 15l/h at 1/4th the
cruising speed or would it be more, or less?


Interesting question. And I can only address my boats which are
outboards.

At WOT, they run around 7.6 to 7.9 G/h - call it 8. At cruise, which
is about 3/4 throttle it averages about six. Can't speak to 1/2
throttle, but at idle (trolling speed) it's less than 3 G/h. Overall,
the way I operate my boats, I average 5 G/h.

What would you call it? :)

All the best,

Tom
