Quick answer
To understand whether a trip will be expensive, cost per mile often explains more than total cost. Then you multiply it by any route.
- Simple formula: L/h divided by knots, multiplied by €/L.
- A fast boat can have acceptable cost per mile if it covers many miles per hour.
- Use it to compare speeds before choosing a trip plan.
Base formula: litres = distance ÷ speed × fuel burn L/h
cost = litres × price per litre
cost = litres × price per litre
