How PLBs improve the chance of rescue at sea

The United States NTSB (National Transportation Safety Board) has reminded operators in the maritime industry of the importance of crew wearing PLBs (personal locator beacons) whilst at sea.  In a recent incident off Alaska when a crabber capsized and sank, because of the weight of the topside ice and the force of the winds and waves, five out of a crew of seven drowned. An investigation by the NTSB found that while the crabbers emergency position indicating radio beacon (EPIRB) continued to operate after the vessel had been abandoned, rescue teams, using the EPIRB position, searched in the wrong area.  Eventually, a Coast Guard helicopter rescued two crew members, who had swum to a life raft, but the remaining five were never found.  https://safetycompass.wordpress.com/2022/12/27/personal-locator-beacons-improve-the-chance-of-rescue-at-sea/
