MOB Alert – Man Over Board System

A Man-Over-Board emergency is a terrifying experience for any captain or crew and key for a safe recovery is to mark the casualty position quickly.  Most chart plotters have a MOB event marker but accessing the function is often buried away in menus and the plotter may be below deck.

The latest yacht racing rules demand a MOB event marker to be within a few feet of the helm and on larger vessels, it may be important to have multiple activation points.

Many boaters are now integrating AIS Beacons into lifejackets so the real-time casualty position can be displayed on plotters but there’s always a delay for the beacon to compute a GPS position and activate a signal and many crew members may not have the expensive technology integrated into the life jacket.

Digital Yacht have also produced an optional, ultra loud alarm that can connect to the boat network and alert independently of the plotter.  This is also self powered from the network so fits in seconds and can also be used as an audio alarm for any other preset NMEA alerts such as depth, wind or engine parameters.

With a output rating of 102dB (same as a jet flying at 100 feet!), this will wake everyone on board!
