The Coast Guard Sector Jacksonville operations center was notified of the maritime distress by the Jacksonville Sheriff's Office at approximately 11:30 a.m., after they received a 911 call via a cell phone. A 47-foot rescue boat crew from Station Mayport responded to the distress and rescued the two men.<br /> <br /> The King Fish, homeported in Mayport, began taking on water approximately one-half mile south of the Mayport jetties. The two men aboard the King Fish reported a towing block had broken loose and punctured a hole in the ship's hull, which enabled water to flood the engine room. In addition, water damaged the vessel's battery equipment, and caused the boat to lose power.<br /> <br /> The King Fish ran aground at Atlantic Beach onboard Naval Station Mayport near the jetties following the rescue. There is currently no report of pollution.<br /> <br /> The Coast Guard reminds all mariners of the vital importance of having safety equipment in the event of an emergency. Professional mariners and recreational boaters are urged to have a working VHF radio, signaling devices and an emergency position-indicating radio beacon.
