Vessels’ extension lines
Sets the lengths of the heading and course extension lines for your
vessel. For setting extension line lengths on other vessels shown as
AIS targets, refer to AIS "Course extension lines" on page 125.
A: Heading
B: Course Over Ground (COG)
The lengths of the extension lines are either set as a fixed distance,
or to indicate the distance the vessel moves in the selected time

lines are shown for your vessel.
Your vessel heading is based on information from the active
heading sensor and the COG is based on information from the
active GPS sensor.
