Target Vector Settings; Collision Avoidance - Raymarine LIGHTHOUSE 3 Advanced Operation Instructions

Note: If 'Full color' is selected for the Radar overlay palette, approaching targets will appear
Pink instead of Red.
• Use COG when no Heading data available — Enables use of the Radar layer when Heading
data is not available.
• Range — Determines the range used for the Radar layer.

Target vector settings

Target vectors show the predicted future path of the target.
Target vector settings can be accessed from the Targets setting menu: Menu > Targets > Target
settings.
The reference mode for vectors can be set to True or Relative.
• In True reference mode, trails, vectors and history are shown ground referenced (i.e. their actual
path over ground).
• In Relative reference mode, trails, vectors and history are shown relative to your vessel's
movement.
Vectors are always displayed for Radar targets. Vectors for AIS targets can be set using the Show
AIS vectors option. The available options are:
• All — vectors are displayed for all AIS targets.
• Manual — vectors only displayed when enabled individually for each target using the target
context menu.
The length of the vector identifies where the target will be after the time specified in Vector period
has passed.

8.6 Collision avoidance

In addition to target tracking specific collision avoidance features are available to improve awareness
for the potential of collisions.
The specific collision avoidance features are:
• Dangerous targets alarm. Refer to:
• Radar guard zones. Refer to:
• Predicted areas of danger. Refer to:
• LightHouse chart obstruction alarm. Refer to:
Chart app
p.152 — Dangerous targets alarm
p.280 — Guard zone alarms
p.152 — Predicted areas of danger
p.161 — Obstruction alarm (LightHouse charts)
