Estimate underway time, fuel burned, trip cost and a planning quantity that includes your chosen reserve.
Enter the total trip distance in nautical miles, the average cruising speed in knots and the boat's fuel burn in gallons per hour. The calculator estimates underway time, multiplies it by hourly fuel use, then applies your local fuel price. The reserve field adds a planning allowance to the estimated fuel quantity.
Use a measured cruise fuel-burn figure for your exact boat, engine, propeller and normal load whenever possible. Brochure numbers and another owner's results may not reflect your setup.
Wind, waves, current, hull fouling, trim, passengers, gear and extended idling can all increase fuel use. A simple cost calculator cannot determine whether a trip is safe or whether the selected reserve is adequate for the route and conditions.
Recalculate when your load, route or expected weather changes. For wider ownership planning, use the boat maintenance cost guide and keep manufacturer procedures plus applicable navigation guidance ahead of any estimate.
