Showing AIS and MARPA Vessels on a Chart or on a 3D Chart View
AIS requires the use of an external AIS device and active transponder signals from other vessels. Mini
Automatic Radar Plotting Aid (MARPA) functionality works with radar
You can configure how other vessels appear on a chart or on a 3D chart view. The display range and MARPA
settings configured for one chart or one 3D chart view are applied only to that chart or to that 3D chart view.
The details, projected heading, and trails settings configured for one chart or one 3D chart view are applied to
all charts and to all 3D chart views.
Note: The Mariner's Eye 3D chart view is available if you use a BlueChart g2 Vision data card. The Fishing
chart is available if you use a BlueChart g2 Vision data card or a BlueChart g2 Data card, or if your built-in
map supports Fishing Charts.
