The location of the Vector options is dependent on
the application and the overlays you have enabled:
• Radar application: Menu > Collision Avoidance.
• Chart application with Radar and AIS overlays
enabled: Menu > Radar & AIS > Collision
Avoidance

16.11 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.
