The U.S. Coast Guard and the Canadian Coast Guard responded to a mayday call at 7:40 p.m. that was sent out by a 406-megahertz EPIRB or Emergency Position Indicating Radio Beacon. The signal was positioned 3 Nautical Miles S.W. of Race Rocks in Canadian waters. The EPIRB allowed rescue personnel to quickly locate the capsized trimeran, the "Red Shift" and her crew of four. A Coast Guard HH-65A Dolphin helicopter from Air Station Port Angeles and the Coast Guard Cutter Osprey were dispatched to respond to the mayday signal of the EPIRB. The Coast Guard helicopter arrived on scene to find three of the crew sitting on the capsized vessel with a fourth trapped inside. The rescue swimmer was lowered from the helicopter into the water. He then assisted the trapped man from the cabin.
