Chart vectors display indicators for heading, COG, wind direction
and tide direction.
A range of vector graphics can be displayed in the chart application
when in 2D chart view. The following vectors can be independently
enabled or disabled:

Note: If Speed Over Ground (SOG) or heading data is not
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 specify at your
current speed.
Enabling and disabling chart vectors

Descriptions
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.
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.
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.
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.
6. Select a time setting or select Infinite.
7. Select Vector Width.
A list of widths is displayed.
8. Select either Thin, Normal or Wide.
