Let's see . . . for us old-timers, that works out to be

10 knots, about 1.4 mpg = 7.14 gallons per hour (gph)

At  11 knots, 1.1 mpg = 10.0 gph

For comparison sake, here are the actual fuel burns from recent long passages:

Dashew 83 Wind Horse 11.5 6.82
Pachoud 60 Wild Wind IV 9.3 5.17
Nordhavn 47 Bacchus 6.2 2.7
Nordhavn 40 Nordhavn 6.67 2.92

The first number is speed in knots, the second is the fuel burn in
gallons per hour.

--Georgs

At trawler speed of 10 knots,about 1.4 mpg.
At 11 knots, 1.1 mpg
top speed 19 to 22 knots. Don't know the fuel burn and don't want to know.

lot of horsepower for passagemaking.

What do you figure your fuel burn will be at trawler speed of 8-9
knots? at your cruise speed of ?? knots?
