Vector descriptions
HDG (heading) vector — a red line shows the vessel’s heading. An arrow head
is used if the vector length is set to a value other than infinite.
COG (Course Over Ground) vector — a green line indicates the vessel’s
actual course. A double arrow head is used if the vector length is set to a value
other than infinite.
Vector descriptions
Tide arrow — tide is displayed as a blue line with solid arrow head pointing
away from your vessel, in the direction of the tidal set. The width of the arrow
indicates the tide strength.
Wind arrow
— wind direction is displayed as a yellow line with solid arrow
heads pointing towards your vessel, indicating the wind direction. The width of
the arrow indicates the wind strength.
Note: If neither Speed Over Ground (SOG) or heading data is
available, vectors cannot be displayed.
Vector length
The length of the HDG and COG vector lines is determined by the
distance your vessel will travel in the time you have specified (3
mins, 6 mins or Infinite) in the
Chart Setup Menu at the current
speed. Any times that you specify will apply to all chart views, and if
the Infinite option is selected, the vector will extend to the edge of
the chart window.
