The report analyzes fall-overboard accidents that occurred on the Great Lakes between 1968 and 1972. None of the victims that fell overboard while the vessel was underway were recovered alive. In many cases it was not known that the victim was missing until many hours later. It is evident that an alarm system of some type is required. The objectives of the study are to investigate various sensor techniques that could be used as a man-overboard alarm, prepare technical descriptions of candidate systems and select the most feasible systems for comparative evaluation. Results indicate that three techniques have possible application. The first is a man-carried transponder; the second is a miniature man-carried RF transmitter; and the third and most promising system is a man-carried sonar pinger.
