Seculmer Locating a person or object in danger at sea using a tethered balloon

SECULMER is based on the idea of a brightly coloured tethered balloon equipped with a light signal that floats well above the waves at the end of a halyard attached to the person or craft in distress. The ultra lightweight balloon, made from a gas-impermeable fabric, is incorporated into clothing or equipment. By simply pulling on a toggle, the balloon inflates and the halyard extends. Those coming to assist can immediately pick up the message and carry out a vertical rescue below the balloon's location.
The SECULMER system is designed for maritime professionals - fishermen, RNLI, tug crews and anyone involved in operations at sea - for crews in long-distance races, those practising watersports (sialing, surfing, angling, etc.), and for use in surveillance and scientific research (drift buoys, ocean measuring equipment and monitoring hazardous areas).
The system establishes a new and simple alarm signal everyone can recognise - "Balloon in the air - vertical rescue required".
