For planning only, not for navigation
BoatCalculators provides estimates for trip planning. Routes, distances, times and fuel figures may be inaccurate, and a calculated line can cross land, shoals or restricted areas. Do not use them for navigation. Always consult official nautical charts, notices to mariners, current weather and sea conditions and local regulations before and during a trip.
