Rate of fuel burn on my trip

[denpooch]

Hi folks. I just got back from a one week cruise from western Long Island Sound up the Hudson River, ending at the junction of the Erie Canal and Mohawk River. It was the first time that I was that far north on the river and this proved to be a great adventure!
In general, I was running her between 3200 and 3400 RPM's for a good portion of the trip. Cruising speed, depending on current and weather conditions was around 17 to 19 mph. My average burn rate was 20 - 22 GPH.
In my mind I think that's pretty good considering that I am moving 18,000 lbs around at a relatively quick pace.

Nice...I guess you came back much faster than going.... ....What equipment are you measuring flow rate with ?

[denpooch]

I top off the tanks and divide total volume of fuel purchased by the number of hours between runs.

Will you post what boat and engines?
