Suitably AIS-enabled vessels (or AIS ‘targets’) appear as triangular
symbols. Up to 100 targets can be displayed.
Vectors can be displayed for each target. These vectors indicate the
direction of travel and rate of turn of the vessel and the distance it
will travel over a specified period of time (COG/SOG vector). Tar-
gets displayed with their vectors are referred to as ‘active targets’
and are scaled according to the size of the vessel.
You can choose to display all targets or just the dangerous ones
