If the vector tick marks are set too high, the predicted ship outline
will be spaced far apart and may not be visible on the display
depending on scale and ship speed.
Predicted ship will be displayed regardless of whether the display setting is
in predicted vector, predicted path or COG vector. When predicted vector is
enabled the location of each predicted ship CCRP is shown as a small dot
on the vector line.
If the system is in water stabilised mode and predicted vector/path is
switched off, the predicted ship outlines continue to follow the ground
stabilised vector path.
Predicted Path
Predicted Path is used to indicate the area that the ship will pass through
based on current speed, course, and rate of turn.
The predicted path is two thick orange lines
originating at the inside fore corner and the
outside aft corner of own ship, if the ship is
turning the lines are shown as arced. A true
scale ship is drawn at the end of the
predicted path.
Fore and aft are relative to the direction that own ship is moving
and do not necessarily relate to bow and stern.
Predicted path is drawn to a maximum vector time of six minutes. The
predicted path is decreased from its maximum length if the vector time is
decreased below six minutes.
If the system is in water stabilised mode the predicted path continues to
follow the ground stabilised vector path.
