A range of vector graphics can be superimposed on to the chart
display. The following vectors can be independently enabled or
disabled:
• HDG (heading) vector — shows the vessel’s heading, displayed
as a line with an open arrow head. It does not take winds or tides
into account.
• COG (Course Over Ground) vector — indicates the vessel’s actual
course, and is displayed as a line with two open arrow heads.
• Wind and tide vectors — winds and tides are displayed as lines
with solid arrow heads in the direction of the wind or tidal set.
Wind arrows point towards your vessel, and tidal arrows point
away. The width of the arrow indicates its strength.
Note: The length of the HDG and COG vector lines is determined
by the distance your vessel will travel in the time you have
specied (3 mins, 6 mins or Innite) in the Chart Setup Menu at
the current speed. Any times that you specify will apply to all
chart views, and if theInnite option is selected, the vector will
extend to the edge of the chart window.
Note: If neither Speed Over Ground (SOG) or heading data is
available, vectors cannot be displayed.
