8.3 Arrival Alarm
The arrival alarm informs you that your boat is
approaching a destination waypoint. The area
that defines an arrival zone is that of a circle
which you approach from the outside of the
circle. The alarm will be released if your boat
enters the circle. When the arrival alarm is
active a dashed circle marks the arrival alarm
area.
