The apps

From the first waypoint to the last line in the log.

Chart ↗
The underway map. NOAA charts coloured against your boat's draft, with tides, currents and your track behind you.
Log ↗
The logbook that fills itself. Outings arrive from Chart, decades of old tracks import from any app, and the days count toward a captain's licence.

A story worth keeping.

Outings arrive from Chart. Old tracks find a new home. Replay the passage, revisit the turns, and build a logbook that goes with you.
