Extension lines
The length of the extension lines for your vessel and for other
vessels can be set by the user.
• A: Heading
• B: Course Over Ground (COG)
The length of the extension lines is either set as a fixed distance, or
to indicate the distance the vessel will move in the selected time
period. If no options are turned on for This vessel then no
extension lines are shown for your vessel.
Your own vessel heading information is read from the active
heading sensor, and COG information is received from the active
GPS.
For other vessels COG data is included in the message received
from the AIS system.
