The OLAS wireless engine kill switch is a safety system for power boats that allows people to move freely on the vessel while staying safe. It has two main parts: the OLAS receiver, installed on the boat, and the OLAS transmitter, worn by the skipper or crew. The receiver communicates wirelessly with the transmitters and constantly monitors their presence nearby. If the transmitter goes out of range or falls overboard, the system activates the engine kill switch automatically. This stops the engine to prevent accidents and injuries, providing an extra layer of safety and peace of mind for boaters.
