Radar wakes (Trails)
Radar wakes enable you to see target history. Wakes will appear
differently depending on whether your radar is set to True motion
or Relative motion mode.
Relative motion mode
In relative motion mode radar wakes appear on targets that are
moving relative to the sea (Sea stabilized) this includes targets
that are fixed to the ground, such as piles.
Wakes do not appear if a target is moving at the same speed
and in the same direction as your vessel.
