I think there are a few people here that can't seem to grasp that fuel usage and speed ..are a combination of power..AND Hull FORM. Let's not forget HULL FORM.

Lets take a typical 22 foot bowrider...AND.. a 22 foot by 12 foot Work BARGE. This barge I describe is an exaggeration to make a point. The barge will never get up on plane so will not realize any fuel saving benefit from "planing" that the bowrider will....Given the same power in both...which one do you think will be most fuel efficient..?? BTW: MPG is a farce when used with boats. Gallons Per Hour (GPH) is what is commonly used with boats..

Then there is Pleasure Vs Work. So you can see there are TOO many Variables to yield ANY Meaningful DATA. Just something to think about.

Boating is intended ......To get away from all the "Confines" of day to day living. You don't have to go...you WANT to go. So JUST GO. It's not like you have to comute to work every day in your boat.

EDIT: BTW: I have a Donzi Classic (20') with a 350 V-8 Mercruiser and my average fuel consumption is 3.5-4.0 GPH. I keep a log book to document this. When I show up at the gas dock I can estimate how many gallons it will take to fill it up. I have an hour meter. I'm usually within a gallon or two. Every boat....AND operator will yield different numbers. Just sayin.
