No way! A 120 Lehman can not burn 12 gals per hour even at WOT into the wind.

Agreed.

Nor will a 36 GB with a single 120 Lehman turn 12 knots.

But I don't think it makes any difference if you are running up or down wind-
that will change your SOG, but fuel consumption will be a function of throttle
setting.


I was reading an archived article from "Soundings" on the GB 36. Here's
a section of the article:

"In many cases, single-engine models provide efficient cruising in the
8- to 9- knot range and burn a stingy three gallons per hour (gph).
Top-end speeds rise to 10 to 11 knots, but fuel consumption jumps to 12 gph"

It doesn't really say what engine. The complete article can be found at:

For Mrs. E, it really doesn't matter. Her personal cruising will
probably be limited to chugging along through the harbor, around
Basset's island and back, all within a 6kt max speed zone.

The most efficient cruising speed for a 36 is about 7+ kts, burning
maybe 2 gph or so depending on conditions. Above that, the demand for
hosepower increases very quickly. A burn rate of 12 gph implies over
200 horsepower.

It looks like a bit of journalistic over exuberance crept into the
article.

It will be perfect for that.

Yup. Journalists seem to have a habit of that.

I think so too.

Bigger single than a 120 Lehman. Perhaps a Cummins.
