Viewing Vessel Trails on the Chart

You can view trails for all tracked vessels on some chart views. By default, a black line indicates the path of the vessel, a black dot indicates each previously reported position of a tracked vessel, and a blue flag indicates the last reported position of the vessel.

  1. From a chart or 3D chart view, select Options > Layers > Other Vessels > DSC > DSC Trails.
  2. Select the number of hours to show tracked vessels on the chart.

    For example, if you select 4 Hours, all trail points that are less than four hours old appear for all tracked vessels.
