Distributed muster for ocean-going vessels

Distributed muster includes distributing to different mobile devices 110 an identity of an assigned muster location 140 of an ocean-going vessel 150, and associating each mobile device both with a corresponding passenger of the ocean-going vessel 160, and also with the assigned muster location. Thereafter, a timer 130 initiates that defines a period during which a muster drill must be completed by all of the passengers and, in response, a message is transmitted to each mobile device that the muster drill has commenced. During the period, as each mobile device is sensed within a geographically defined area of a correspondingly assigned muster location, a record of the completion of the muster drill by the passenger associated with the sensed mobile device is recorded in the memory. As well, subsequent to a lapsing of the timer, a listing 170 is displayed of any passenger not recorded as having completed the muster drill.
