Does that sound right??
We left Annapolis on May 8th and are now in Ottawa. We have used about 570 gallons of fuel running 145 hours which is 4 GPH at 1,650 RPM, generally. This included about 30 hours of generator time. Our boat is a 56,000 pound Defever 44 with Lehman 120s.
An interesting side note: We had to run on run engine from Ottawa to Manotick, Ontario. We cruised at 1,250 RPM which yielded 5 MPH on the flat, no-current Rideau River (between the locks).
