EPIRB - Emergency Position-Indicating Radio Beacon
Voor het geval dat een bemanningslid onbedoeld overboord valt en het achterblijvende lid bij bewustzijn is en de tegenwoordigheid van geest heeft om de overboordgevallene een baken na te werpen, is er een EPIRB aan boord dia grijpbaar aan de achtersteven is bevestigd. Eenmaal in het water geeft hij zijn positie door via satellieten en begint met een licht te flitsen totdat de accu's leeg zijn. Als drenkeling blijf je zo dicht mogelijk bij de EPIRB totdat er aan de hemel een helikopter verschijnt met redders in de nood. Als het 82 maagden blijken te zijn heb je (eerder al) pech gehad.

Distress radio beacons, also known as emergency beacons, PLB (Personal Locator Beacon), ELT (Emergency Locator Transmitter) or EPIRB (Emergency Position-Indicating Radio Beacon), are tracking transmitters which aid in the detection and location of boats, aircraft, and people in distress. Strictly, they are radiobeacons that interface with worldwide offered service of Cospas-Sarsat, the international satellite system for search and rescue (SAR). When manually activated, or automatically activated upon immersion, such beacons send out a distress signal. The signals are monitored worldwide and the location of the distress is detected by non-geostationary satellites, and can be located by some combination of GPS trilateration and doppler triangulation.[1]
The basic purpose of a distress radiobeacon is to help rescuers find survivors within the so-called "golden day"[2] (the first 24 hours following a traumatic event) during which the majority of survivors can usually be saved.
Since the inception of Cospas-Sarsat in 1982, distress radiobeacons have assisted in the rescue of over 28,000 people in more than 7,000 distress situations.[3] In 2010 alone, the system provided information which was used to rescue 2,388 persons in 641 distress situations.[4]
