Ship’s Track Mark*					With heading and speed data, own ship’s track is plotted by a solid
					line. The track length can be selected among five or ten times the
					range. When the length exceeds the chosen length, the track is
					erased so that its length is equal to the chosen length.
Current			3		This mark can be displayed with current indicator input. The current
					marks show tidal current speed and direction in three layers (1-3),
