To cross the Atlantic an average motorized yacht would need a tank with a capacity of about 5000 liters of fuel at a fuel efficiency of 25 nautical miles per gallon.

How much fuel does a mega yacht use. As an approximate guide a yacht of 70 meters will consume about 500 litres of diesel an hour when the engines are running but not moving. If your sailing itinerary contemplates 150 nautical miles at a constant cruising speed of 18 knots 250 lthr consumption and marine diesel cost of 150 Eurolt at the end of our yacht charter we will have a bill of 312375 Euro. Our experts will suggest the best places to take on fuel and our long-standing supplier relationships mean you get premium quality fuel at competitive prices.

The cost of a yacht moving will be approximately 2000 an hour to achieve cruising of around 18 knots. About 200 grhp-h They do not say that consumption occurs under ideal navigation conditions with the engine at 80 but is data that can be used with caution. For comparison a private motor yacht between 40 and 60 feet only carries 200 to 1200 gallons while something massive like the Exxon Valdez carries up to 55 million gallons.

Imagine trying to fill the tank with a regular fueling nozzle a couple of days later its almost full. As vessels shrink in size so does their fuel consumption. Thats the equivalent of refilling a typical hatchback car more than 23800 times and the same amount of fuel could fill up almost six Boeing 747 commercial airliners.

Theres no such thing as a typical super yacht so lets just pick an example a. The yachts that this service certainly applies to are ones that may not have the motoring range or structural integrity for blue ocean cruising. This would be for a fuel use rate of 4 gallons per hour at 10 knots cruising speed.

The main engines are twin Pielstick diesel engines each with power of 7990 hp. To put that in perspective thats equivalent to over 80000 gallons of fuel a day. The result represents the approximate gallons per hour the engine will burn at wide-open throttle.

OK a little more detail. So I have decided to create a user-submitted database of boats and their fuel economy. These huge yachts have fuel capacities of 10000 - 20000 gallons sometimes more.
