Quick answer
The practical question is not what a boat uses in theory. It is what it will cost to reach a specific port with your boat, your speed and today’s fuel price.
- Start with the one-way distance in nautical miles.
- Enter the combined fuel burn of all engines in litres per hour.
- Multiply running hours by hourly burn and fuel price.
Base formula: litres = distance ÷ speed × fuel burn L/h
cost = litres × price per litre
cost = litres × price per litre
