At 4 - 5 knots into wind and waves a consumption of 1.8 CND gallons per hour is
possible.
Very roughly a 4 stroke gas engine running efficiently will yield about 15 HP
at 1 gallon CND per hour.
Subtract losses for the alternator and water pumps and 1.8 might give you 20 -
24 HP at the prop.

Hi Jay,
Fuel estimate for Sweet when she had the A4 was 4
litres per hour at cruising speed. Speed range
was 3 - 5.5 knots (depended on conditions) with a two blade fixed prop.

If you were motoring into wind and waves, you were more than likely "making
bubbles". That is, in order for you to get to the full horsepower of the
AT4, you were near
Hello colleagues
Filled with gas for the Atomic 4 in Port Whitby Canada Day and sailed back to
Toronto. Wind out of the West and tight timeline meant we had to motor against
the wind and waves for 2.5 hr. That would be relatively “hard” motoring at 4-5
knots. Since then I’ve motored about
