Quick action by Fernandina Beach lifeguards and firefighters led to the rescue of a 17-year-old from Brunswick. The teen was one of three people pulled out by a rip current at Peters Point on Saturday. “We got dispatched to three swimmers in a rip current and they were starting to get farther and farther out,” Haynes Cavender said. The Fernandina Beach Ocean Rescue supervisor said 15 lifeguards were doing CPR and first aid training at a facility off-site when the call came in. He grabbed two trainees with experience and rushed to the beach while the fire department sent two rescue swimmers. The county also dispatched its rescue boat. Cavender said when the lifeguards got to the beach, two swimmers had gotten themselves to safety, but the third was 300 yards out.
