Automatic AIS MOB Follow Mode - for Tecnautic and other Autopilots

joystick Vessel automatically returns to a crew member's personal AIS beacon
When an AIS SART or MOB beacon of the own crew is received, the autopilot starts beeping and flashing and the engines automatically go into idle and out of gear. Well proven since 2014.

red Installation: plug the tiny Add-On directly into the NMEA2000 Bus or SeatalkNG Bus, where it has AIS and Autopilot data. Use a PC to write your beacon MMSI numbers over the Bus into the device.

Personal AIS MOB beacon fitted to life west:
S20-2

The AIS MOB beacon sends its first signal immediately after activation, without getting a GPS fix - long before the target is shown on the plotter. The vessel might only be 15 seconds away, when the engines go out of gear and into idle. Yachts can be turned into the wind. s20-3

Automatic target tracking will start one minute after first reception. It may be interrupted and can resume with an installed MOB button. Initially the vessel turns towards the target and accelerates up to 6 kn, depending on distance.
The Autopilot will reduce speed and come to a halt at relative speed zero in front of the target, at 30 m (100 ft.) antenna distance. It will stay out of gear to permit a safe recovery. If the target drifts away, farther than 55 m (180 ft.), the Autopilot will home in again.
