•  Bearing Reference—sets your bearing, either Absolute or Relative. 

Relative calculates the bearing relative to own vessel heading. Absolute 

calculates the bearing referring to North. 

•  Navigation Features—allows you to show or hide navigational features on 

the Radar Page. Use the ROCKER and the ENTER key to select or clear 

options.

  •  Waypoints—show user waypoints on the Radar Page.
   •   Bearing Line—show a bearing line on the Radar Page. The bearing 

line appears as a line from your current position to the active destination 

waypoint, similar to a traditional lollipop.

  •  Course Line—show a course line from your starting point to the    

  active destination waypoint, which is similar to navigation on a map.

The MARPA sub tab contains settings for Vector Length, Target History, Own 

Vessel Safe Zone, Tine To Safe Zone, Safe Ring Zone, and Velocity Reference.

The available MARPA sub tab options are:

•  Vector Lenth—predicts the target’s approximate position at a set time 

interval. This setting determines the length of the Vector Line, based on the 

time interval setting and the target’s speed. The time interval settings range 

from .05 minutes to 60 minutes.

•  Target History—is a trail showing a target’s movement. Target History 

can be turned On or Off.

•  Own Vessel Safe Zone—is a circular area defined by a range setting that is 

centered on your own vessel. If a target enters the defined area an alarm is 

sounded. The Safe Zone can be set to a distance between .01 and 2 nautical 

miles.

•  Time To Safe Zone—sounds an alarm if MARPA determines that a target 

will intersect the Own Vessel Safe Zone within the defined time interval. 

The time interval settings range from 3 to 24 minutes.

•  Safe Zone Ring—displays a ring on the Radar Page depicting the Own 

Vessel Safe Zone.

•  Velocity Reference—has two settings, Absolute and Relative. This 

setting determines how speed and direction are displayed on the MARPA 

list. Relative calculates target speed and direction relative to your own. 

Absolute shows the target’s actual speed.
