Boat Fuel Range Calculator
Estimate how far a boat may travel on available fuel while keeping a reserve for wind, current, detours, and the return trip.
How to use this calculator
- Enter the fuel available, expected fuel burn, and reserve amount.
- Use realistic speed and fuel-use numbers from your boat, motor, and load.
- Compare calm-water and rough-water scenarios before leaving.
- Keep a conservative reserve instead of planning to use the full tank.
Example uses
Fishing run
Estimate whether a long run to a fishing spot leaves enough fuel to return.
Lake cruising
Plan a route with several stops while preserving reserve fuel.
Weather margin
Compare range when wind or current increases fuel burn.
Helpful notes
- Boat fuel burn changes with load, trim, hull condition, prop, wind, current, waves, and speed.
- Use this for planning only and verify fuel needs with your own boat records.
- Carry a margin and follow safe boating practices.
