About the Nautical Mile Trip Calculator

Planning a boat trip means estimating both how long it will take and how much fuel it will burn at a given cruising speed, since running out of fuel offshore is far more serious than on the road.

Formula: Trip Time = Distance (nautical miles) ÷ Cruising Speed (knots); Fuel Used = Trip Time × Fuel Burn Rate; Fuel Cost = Fuel Used × Price per Gallon.

Always add a safety margin of extra fuel beyond this estimate for wind, current and detours.
