7.1.7 Placing Ship Marks
A ship mark is an placed at the ship's location and labeled with the time it was
set, Figure: 7−10.
You can use the Mark at Ship command to annotate tracks with your own ship
marks. The Auto Label command will place a ship mark at your boat's location at
specified time intervals, nautical mile intervals, or at specific headings.
Mark at Ship command will place a single ship mark at your ship's location
when the command is chosen. You may find these commands useful for docu-
menting such events as the arrival at a waypoint.
ECDIS also sets a ship mark whenever a new navigation device
becomes active (see "Selecting the Navigation Devices", chapter 7.1.2).
These marks are labeled with a one− or two−letter abbreviation for the
type of device in use.
