How Many Miles Gallon In A Commercial Catamaran?

Going from one engine to two engines does not significantly increase speed but doubles fuel consumption. Turning on engine number two will give seven knots. On average, a cabin cruiser boat gets around 1 mpg (miles per gallon) at MAX RPMs. However, the mileage can vary from 0.5 mpg or less to 2 mpg or more depending on the weather condition.

A rough estimate of the fuel consumption to push a 40ft cat at hull speed is about.7-1.0 gallon per hour, at a speed of about 6-8 knots. Calculating a boat’s fuel consumption is important for boaters as it helps anticipate the safe distance you can cover with a specific fuel. Fuel consumption ranges from 1,585 to 2,640 US gal (6,000 to 10,000 l).

The rule of thumb is that 10% of horsepower rating per hour is approximately 20 galshour. A Panamax container ship can consume 63,000 gallons of marine fuel per day at that speed. Fuel use drops sharply as speeds decrease. A 40 footer doing 7 kts will typically get somewhere in the range of 2.5 and 3.5 nautical miles.

Depending on hull form and engines, a 40 footer doing 7 kts will typically get somewhere in the range of 2.5 and 3.5 nautical miles. A Yamaha F300 can get 3.5 mpg at 30 mph, making it suitable for fishing offshore from Ponce inlet out 50 miles in the stream and crossing to other locations.
