This feature is intended to enhance situational awareness and may not prevent collisions in all circumstances. You are responsible for the safe and prudent operation of your vessel and for remaining aware of obstacles or hazards in or around the water. Failure to do so could result in an accident causing property damage, serious personal injury, or death.

Mini-automatic radar plotting aid (MARPA) enables you to identify and track targets and is primarily used for collision avoidance. To use MARPA, you assign a MARPA tag to a target. The radar system automatically tracks the tagged object and provides you with information about the object, including the range, bearing, speed, GPS heading, nearest approach, and time to nearest approach. MARPA indicates the status of each tagged object (acquiring, lost, tracking, or dangerous), and the chartplotter can sound a collision alarm if the object enters your safe zone.

Before you can use MARPA, you must have a heading sensor connected and an active GPS signal. The heading sensor must provide the NMEA 2000® parameter group number (PGN) 127250 or the NMEA® 0183 HDM or HDG output sentence.
