About this route

An 18-nautical-mile bay passage under sail over four hours, tacking across the wind at sea level. Switch the units to nautical and speeds read in knots, which is the natural frame for sailing. Elevation is flat throughout, so this file is all about speed and heading.

This is a synthetic sample: the coordinates are plausible for Sheltered bay (open water, no roads to trace) and contain no personal GPS data. Public domain — CC0 1.0.

Common questions

How do I see knots?

Set the units toggle to nautical (kn). Distances then read in nautical miles and speeds in knots.

Why is elevation zero?

It is a sea-level passage; every point sits at 0 metres, so there is no gain or loss to report.
