Launched to reports of two Kayakers in difficulty on Fairy Buoy. The person was seen to climb onto the buoy & started waving his arms. Porthcawl National Coastwatch informed U.K. Coastguard who requested immediate launch of Porthcawl Lifeboats. The person then entered the water to swim back towards the drifting kayak. On our arrival on scene a few minutes later the casualty had managed to reboard the craft unaided.
