ABSTRACT:
The device has a source of acoustic signals placed beneath the hull of the boat, a beacon, an alarm pack worn by the navigator around the neck. If the navigator falls overboard, an acoustic sensor built into the pack detects the emission of the source and actuates the jettisoning of the beacon by remote control. This beacon has a measuring head fitted out with a directional acoustic sensor and a compass capable of computing information on the position of the beacon, transmitted by radio to a control box fixed in the boat. As the beacon is supposed to be near the castaway or man overboard, he is thus found.
