RedactedNarrative: The Coast Guard rescued three boaters Wednesday after their vessel capsized 8 miles east of Tybee Island, Georgia. According to the report, watchstanders at Coast Guard Sector Charleston received a single call at 2:15 a.m. from a male voice saying "mayday". Rescue 21, a search and rescue technology tool which assists search coordinators with location based on radio signals, provided an approximate position of the vessel. A Coast Guard Station Tybee Island 45-foot Response Boat – Medium crew and an Air Station Savannah MH-65 Dolphin rescue helicopter crew launched at approximately 2:54 a.m. and began searching. The report states that at 3:22 a.m., the RB-M crew noticed a flashing light which was being used by the crew of the vessel and shortly after located three males and their capsized 32-foot century boat. The RB-M crew embarked the boaters and transported them to Station Tybee Island where EMS were waiting. "The coordination between the responding units and search and rescue mission coordinators as well as the VHF radio and flashing light that the crew of this vessel used were all instruments and critical links that led to the successful rescue of these boaters," said, a search and rescue controller at Sector Charleston. "Furthermore, not only did Rescue 21 pick up the call, but the direction finding gear on the two remote fixed facilities led us right to the boat in distress." One boater suffered a minor shoulder injury.
