Sailing calculator guide
Using calculators as planning aids
The sailing calculators estimate common passage-planning values such as distance, time, speed, fuel use, and basic navigation relationships.
Enter conservative assumptions for fuel, speed, reserve time, and weather delay.
Recalculate when wind, tide, route, or crew readiness changes.
Keep a manual backup and cross-check important numbers before departure.
Calculator outputs are educational estimates and may not account for every vessel, route, tide, current, or emergency condition.

How to use the Sailing ETA Calculator
Estimate arrival time using distance and speed.
Sailing ETA Calculator helps turn simple onboard inputs into a practical planning estimate. Estimate arrival time using distance and speed.
Use the result as a starting point only. Conditions, tide, sea state, crew ability and boat condition can change the real outcome, so always plan conservatively and verify with official guidance.
