Setting the waypoint arrival circle
For route navigation it is recommended to use automatic
waypoint shift/change at a set waypoint arrival circle.
The arrival circle should be adjusted according to boat speed.
The higher speed, the wider 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 on the GPS/chart plotter.
