At 10 mph, I think you'll be pushing a lot of water instead of efficient planing-- but of course, will see a lot of scenery and that alone will make the extra fuel consumption worthwhile. this is a SWAG (scientific wild-assed guess) but would guess you'll "enjoy" about .75 mi/gal or a little less depending on what weight you are carrying such as full water / fuel tanks, number of passengers, cases of adult beverages.

I just completed a 140 mile trip to move from one marina to another. At about half way I had to fuel up so after starting with a full tank I logged 67 miles from marina 1 to the refuel marina. I took 70 Gal of gas to fill her back up.

I was running around 13-14 MPH slower coming out of the marina and had a couple of sprints to 20 mph just to see how the boat was running.

Over all right at about 1 mile per gal.

I did not refuel at the destination marina so can not tell you how we did on the second half of the trip.

I have a 1973 32' express with flying bridge.

I was happy with the mileage.

Will have fuel sensor in place for spring but did not get it set up before the trip.

Nice record keeping and reporting. One note to add. Boats ain't cars. Tide, current, wind will have a much greater effect on fuel use than with a car. Oh, and the amount of weight you're carrying.
