Using Charts

When course over ground, heading, and rate of turn information

are provided by an activated AIS target, the projected course of the

target is calculated based on the course over ground and the rate of

turn information. The direction in which the target is turning, which

is also based on the rate of turn information, is indicated by the

direction of the barb at the end of the heading line. The length of the

barb does not change.

Showing AIS 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.
You can configure how other vessels appear on a chart or on a 3D

chart view. The display range 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 Fishing chart and Mariner’s Eye 3D are available with a

preprogrammed BlueChart g2 Vision data card.
