Waypoint arrival circle
The Arrival radius defines the point at which a turn is initiated when you are navigating a
route.
The arrival circle 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 waypoint circle when creating the
route.
Boat speed in knots
30

Example: With the speed of 20 knots you should use a waypoint circle with radius 0.09 nm.
¼ Note:
The distance between any waypoints in a route must not be smaller than the radius
of the waypoint arrival circle when using automatic waypoint shift.
Sailing with the autopilot
Several sailing parameter should be defined before entering Wind or WindNav mode.
These parameters are described in the separate installation manual.
