• If the required course change to next waypoint is more than the set limit, you are
prompted to verify that the upcoming course change is acceptable. If the turn is not
accepted, the vessel will continue with the current set heading.
Course change less than set limit Course change larger than set limit
Refer to "Course change limit" on page 33.
Track offset
The track offset options allows for steering parallel to the track in NAV mode.
To activate the track offset option:
• press and hold the rotary knob
The display will change to show current distance from track, XTD (A) and set offset, OFF
(B)
Turn the rotary knob to adjust the offset distance. The blue line (C) shows the offset in
relation to the track.
The system will remain in track offset mode for as long as there is an offset value. It will time
out when the offset distance is set to 0 (zero).
Waypoint arrival circle
The arrival circle (radius) defines the point at which a turn is initiated when you are
navigating a route.
The arrival circle is set in your chart plotter.
The arrival circle (1) should be adjusted according to boat speed. The higher the speed, the
wider the circle. The intention is to make the autopilot start the heading change in due time
to make a smooth turn onto the next leg.
The figure below may be used to select the appropriate arrival circle when creating the route.
