Cape Town - The National Sea Rescue Institute (NSRI) cautioned the public about storm conditions on the country's coastlines over this weekend and into next week, after it had to attend to two fishermen on Saturday. At 08:12 on Saturday, the NSRI's East London duty crew were activated following a request for assistance from the ski-boat Real Nauti, who reported that one of their three crewmen had suffered a head laceration, after being swept off the boat by a wave while fishing six nautical miles off-shore of the Kei River Mouth. They had been taking part in the Jikeleza Fishing Competition, according to the NSRI statement.The East London NSRI had been on standby for the start of the fishing competition, and a rescue vehicle was dispatched to Yellow Sands. "The local fisherman, aged in his 30s, had been recovered onto the ski-boat and they brought him to Yellow Sands where our rescue swimmers waded into the surf to help the boat to be recovered, and the injured fisherman was treated for a head laceration," said Geoff McGregor, NSRI East London station commander, according to the statement.Alderson private ambulance services transported the man to a hospital in a stable condition.Also on Saturday morning, the NSRI's Port Edward duty crew headed to Leisure Bay at 09:51, when a man was swept out to sea after being washed off the rocks while fishing. "The sea rescue craft Discovery 6 and our sea rescue vehicle were dispatched and Police Search and Rescue and Medivac private ambulance services responded," said Alan Stilwell, NSRI Port Edward duty controller."On arrival on the scene, we found a 35-year-old off-duty local lifeguard, who had been fishing from the rocks and was swept off the rocks by a wave. He had managed to swim back to shore, but he had suffered bruises and lacerations to his body after being swept against rocks, but he was safe out of the water."NSRI medics treated the man and handed him over into the care of Medivac paramedics, who took him to a hospital in a stable condition. The NSRI also responded to two incidents on Thursday and one on Friday. Fears that yacht was running agroundIn the first incident, a ski-boat with six crew members on board suffered mechanical failure four nautical miles of Gordon's Bay, said Alan Meiklejohn, NSRI Gordon's Bay station commander.The crew and their boat was found safe and towed to Gordon's Bay, in an operation that started at 09:47 and was completed around 14:00. On Friday, the the Gordon's Bay NSRI's duty crew were again activated to assist a ski-boat suffering motor mechanical failure. A father and his son were on board, one nautical mile off-shore of Strand.The crew and their boat were found safe and they were towed into Gordon's Bay Harbour.The operation, which started at 15:08, was completed at 19h00.On Thursday at 10:15, the NSRI at Shelly Beach were alerted to investigate a yacht reported by witnesses to be very close to the surf-line, and fears were that the yacht was running aground.The skipper of the yacht Blue, heading from Durban to East London, had come ashore to collect supplies, while five family members remained on board. When they tried to get back out to sea, they were unable to raise the anchor."Before any assistance was rendered, they were then able to raise the anchor and they motored out to sea a safe distance from shore, and lifeguards launched a rescue rubber-duck to take the skipper back out to his yacht with his supplies," said Jeremiah Jackson, NSRI Shelly Beach station commander.The skipper then informed NSRI that he was heading back to Durban under sails for repairs, and NSRI Durban and NSRI Shelly Beach monitored his progress until they were safe in the Port of Durban around 22:00 that evening.
