The numbers are in

One of the primary reasons we bought this boat was because of the projected fuel economy of the small Yanmar diesels. Today we filled the fuel tanks for the first time since the initial fill.

We have run 30 miles around the St Charles area then 310 miles from St Charles to Green Turtle Bay Marina in Kentucky. In addition to the 340 miles we had seven hours on the generator.

The fuel fill was 95.4 gallons. If we allow the 5.4 for the generator we did 340 miles on 90 gallons or 3.78 miles per gallon. This is right in the neighborhood that we expected and we are extremely pleased.

The number is open to some interpretation, we had a net current assist with more favorable current on the Mississippi then hindering current on the Ohio and Cumberland. We also ran wide open for a period of time on the Ohio that we know reduce fuel economy.

I'll take this set of numbers as they are, be pleased, and wait and see what the next numbers are.
