You can use aerial photographs of landmarks, marinas,
and harbors to help orient yourself to your surroundings or
to acquaint yourself with a marina or a harbor prior to

Automatic Identification System

The Automatic Identification System (AIS) enables you to
identify and track other vessels, and 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), location, GPS
speed, GPS heading, time that has elapsed since the last
position of the vessel was reported, nearest approach,
and time to the nearest approach.
Some chartplotter models also support Blue Force
Tracking. Vessels being tracked with Blue Force Tracking
are indicated on the chartplotter with a blue-green color.

AIS Targeting Symbols

Symbol Description
AIS vessel. The vessel is reporting AIS infor-
mation. The direction in which the triangle is
pointing indicates the direction in which the
AIS vessel is moving.
Target is selected.
Target is 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. If the AIS trans-
mission from the vessel is lost, a message
banner appears.
Target is lost. A green X indicates that the AIS
transmission from the vessel is 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.

Heading and Projected Course of Activated AIS
Targets
When heading and course over ground information are
provided by an activated AIS target, the heading of the
target appears on a chart as a solid line attached to the
AIS target symbol. A heading line does not appear on a
3D chart view.
The projected course of an activated AIS target appears
as a dashed line on a chart or a 3D chart view. The length
of the projected course line is based on the value of the
projected heading setting. If an activated AIS target is not
transmitting speed information, or if the vessel is not
moving, a projected course line does not appear.
Changes in the speed, course over ground, or rate of turn
information transmitted by the vessel can impact the
calculation of the projected course line.
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.
Description
Dangerous target in range. The target flashes
while an alarm sounds and a message banner
appears. After the alarm has been acknowl-
edged, 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.
Dangerous target is lost. A red X indicates
that the AIS transmission from the vessel is
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.
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.
