![Fig 1. The "Show vessel track" button in a vessel's popover](vessel-tracks-1.jpg)

See where another AIS vessel has been by showing its recent track (trail) on
the chart.

**To show every vessel's track at once**, turn on **Show Track** under
**Settings → Vessels → Other Vessels**. Every AIS vessel's track then draws
on the chart.

**To follow just one or two vessels** instead of cluttering the chart with
everyone's track, leave that setting off and pick vessels individually: tap
a vessel on the chart to open its popover, or find it in the AIS vessel
list, and use the **track** button (labelled **TRACK** in the list) to turn
its track on or off. Your picks apply for the current session only — they
aren't saved between visits.

The per-vessel picker is only available while **Show Track** is off; with it
on, every vessel is already shown, so there's nothing to pick.

Track data comes from your Signal K server, so no extra setup is needed
beyond what tracking already requires on the server side.
