CrewWatcher is an app-based crew overboard alarm system that is the fastest way to rescue a person who is overboard. The system works like a virtual lifeline and is made up of two components: a smartphone application and a small beacon that can be comfortably worn by each crew. The beacon does not require complex manual activation. The alarm will trigger automatically in a Man Overboard (MOB) event. Should someone go overboard, after sounding the alarm, the app will automatically provide lat/long coordinates of the MOB event, the time of the event, and will visually guide the rescuer using the virtual MOB compass. #Crew 2 includes two beacons; for only 1 beacon, please see the #Crew 1 item.
