Vector display at primary position
In the own ship symbol, COG (Course Over the Ground) vector, HDG (Heading) vector, and heading
line can be displayed. The COG or HDG vector can also be displayed by the length proportionate to
the current ship speed in minute by the setting. For example, when the vector length is set to 10
minutes, the vector tip is at the predicted position after 10 minutes if the ship is assumed to navigate at
the current speed.
• To display the COG (Course Over the Ground) vector, check [Ground Stabilised Vector] in [Vector].
• To display the HDG (Heading) vector, check [Sea Stabilised Vector] in [Vector].
