AIS SARTs

An AIS man overboard (MOB) beacon uses an AIS signal to transmit the position of a person overboard to all vessels equipped with an AIS receiver or transponder. An AIS SART can be used to locate a life raft or lifeboat in an emergency situation.

An AIS SART with its position close to the waterline and limited 2W output would typically have a maximum range of 5-6NM. A MOB device would typically have a range of 2-3NM.
