Two brothers, David and Martin Marney from Newquay, put their first aid training to use when they came to the rescue of a woman swept out to sea off Little Fistral Beach.
It's believed the woman, who is in her 30s, went after her dog last night when she was caught by a wave and taken 60m out to sea.
The men saw her and used a life ring to save her. They supported her until she was winched to safety by the helicopter from RNAS Culdrose. She was taken to the Royal Cornwall Hospital in Truro suffering from hypothermia. She has now been discharged.
Falmouth Coastguard say she was 'lucky to be alive"
