A device, developed by the Indian Space Research Organisation (ISRO), for sending a distress signal when stranded at sea, will be made available to some fishermen in the state by the Coast Guard. There are 80,000 fishing boats registered in the state and nearly 15,000 set out to sea every day. In the absence of any equipment to send a distress signal, many fishermen drift away and never make it back home. “Bigger vessels are equipped with the mandatory Global Maritime Distress Safety System which can be used to give a distress signal during bad weather, but smaller vessels don’t have this system,” said a Coast Guard official. As a pilot project, the coast guard is giving out 50 units of the Distress Alert Transmitter (DAT). Whenever a fisherman is stranded or at risk, he just needs to press a button on the device and maritime security agencies will receive an alert.
