Wow
So 26 litres an hour for 11 knots (2.3 l/nm)
Compared to
8 litres an hour at 7 knots (1.14L/nm)

I know which fuel bill I lean towards
Fuel burn underway comes in at 6.9 gallons/26 liters per hour of which 0.7 gallons/2.64 liters is used to generate hydraulic and electric power. Most of the trip was run at 11 knots with only a brief period of short hops in Canada spent at a more efficient 10-knot speed
So 26 litres an hour for 11 knots (2.3 l/nm)
Compared to
On a displacement boat of 40 – 50 ft your best fuel economy will most likely be a bit under hull speed, or about 6 - 8 knots.
On Lifeline we travel at 7 knots at 1150RPM, which gives us fuel economy of 8 litres (2 US gallons)per hour or about 3 tenths of a gallon to go 1 nautical mile.
