Vessel vectors (CPA graphics) overview
CPA graphics show vectors for your vessel and a selected target.
A vector is a line on-screen showing the predicted courses of your
vessel and the selected target if you both remain on your present
course. These vectors vary in length due to vessel speed and vector
length set in the MARPA Set-up menu.

CPA graphic
True motion
With the display set in true motion mode, the vectors of your vessel
and the target are shown extended to their intersection point. The
CPA is shown as a line that is placed on your vessel’s vector at
the point of the CPA. The length and direction of the line indicates
the distance and bearing of the target at CPA. The text indicates
CPA and TCPA. The text next to the target symbol indicates its true
course and speed.
Relative motion
With the display set in relative motion mode, no vector extension of
your vessel is shown. The CPA line emerges from your own vessel,
with the target vector extension being shown as relative, not true.
The text next to the target indicates its course and speed.
