He then swam him safely to shore through the surfline.At that stage additional NSRI crew and craft were arriving on the scene. The 60 year old man, from Randfontein, was treated for hypothermia. By Grace paramedics checked on him but he required no further assistance after being re-warmed.TO REPORT A SEA RESCUE EMERGENCY DIAL 112 FROM A CELLPHONE
