Charts and 3D Chart Views 

The Automatic Identification System (AIS) enables you to identify and track other vessels.

AIS alerts you to area traffic. When connected to an external AIS device, the chartplotter can 

show some AIS information about other vessels that are within range, that are equipped with a 

transponder, and that are actively transmitting AIS information. The information reported for each 

vessel includes the Maritime Mobile Service Identity (MMSI), the location, the GPS speed, the 

GPS heading, the time that has elapsed since the last position of the vessel was reported, the nearest 

approach, and the time to the nearest approach.

Description
AIS vessel. The vessel is reporting AIS information. The direction in which the triangle is 

pointing indicates the direction in which the AIS vessel is moving. 
Target has been selected.

Target has been activated. The target appears larger on the chart. A green line attached to 

the target indicates the heading of the target. The MMSI, speed, and direction of the vessel 

appear beneath the target, if the details setting has been set to Show (

page 17

). If the AIS 

transmission from the vessel is lost, a message banner appears.
Target has been lost. A green 

X indicates that the AIS transmission from the vessel has 

been lost, and the chartplotter displays a message banner asking whether the vessel should 

continue to be tracked. If you discontinue vessel tracking, the lost target symbol disappears 

from the chart or the 3D chart view. 
Dangerous target in range. The target flashes while an alarm sounds and a message banner 

appears. After the alarm has been acknowledged, a solid red triangle with a red line attached 

to it indicates the location and the heading of the target. If the safe-zone collision alarm has 

been set to Off, the target flashes, but the audible alarm does not sound and the alarm banner 

does not appear (

). If the AIS transmission from the vessel is lost, a message banner 

appears.
The location of this symbol indicates the closest point of approach to a dangerous target, and 

the numbers near the symbol indicate the time to the closest point of approach to that target. 
Dangerous target has been lost. A red 

X indicates that the AIS transmission from the vessel 

has been lost, and the chartplotter displays a message banner asking whether the vessel 

should continue to be tracked. If you discontinue vessel tracking, the lost dangerous target 

symbol disappears from the chart or the 3D chart view.
