Ship Track

Toggling  the track icon   turns tracking on and off. When tracking is on, the button becomes slightly larger and darker (shown here). Tracking means that a record is kept of the vessels position as it proceeds. A trail is left behind the vessel.
The way the track is recorded can be set in Options -> Ships -> Ownship.
A full explanation is available in Ownship



Recorded tracks can be imported, exported and managed using the The Route Manager and Gpx Data.

When right clicking on a track you can select Track Properties from the context menu, and a new dialog pops up. The same thing can be achieved through the Route Manager. A record of all the track point will be listed. On the screen dump below the tracking precision is set to "Medium". The Waypoints, track points really, appears at irregular times, due to the smart tracking. Only trackpoints that contributes to the track are recorded. In other words, a change in the track occurs at every recorded trackpoint.
Click  anywhere on a line in the list of track points, to mark the line and a blue square will mark the position on the track.



From the right click menu the Delete track option is available as well. To prevent mistakes a confirmation dialog pops up.
For more about Tracks read about the Route Managers Track Tab in The Route Manager and Gpx Data.
