3.11.2 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 red dashed circle marks the arrival alarm area. Note that the arrival alarm and anchor watch alarm can be turned on together.
