5.12 Chart mode and orientation
Mode settings control how the chart displays information. You can
synchronize the chart display with the radar application; set how
movement is represented; set the position of your vessel’s repre-
sentation on-screen, and choose your preferred chart orientation.
Find
This is a shortcut softkey that has the same effect as the FIND key
on the default toolbar. It centers the chart display on either the cur-
sor or your vessel.
Orientation
Orientation settings control the way the chart is drawn in relation to
your vessel’s position and course.
North Up (N-up)
In North Up mode, the chart is static and oriented with true north
upwards. As your heading changes, the boat symbol rotates
accordingly. This is the default mode.
Heading Up (H-up)
In Heading Up mode, the on-screen representation of your vessel
remains static, with your current heading facing upwards. When
you change heading, the chart rotates accordingly.
You cannot select Head Up when the motion mode is set to True.
To prevent continual chart rotations as the boat yaws, the chart will
only update when your heading changes by at least 10 degrees.
