A 38-year-old man had to struggle from the sea with a broken leg after a kite surfing accident off Shoeburyness, Essex, on Wednesday evening.
The injured man managed to get to shore using his kite and called on a jet-skier for help.
Emergency services were called to the beach in front of the Officers Mess at the Garrison at about 2050 BST.
The kite surfer had managed to climb onto a wall to avoid the incoming tide when paramedics arrived.
An Essex Ambulance Service spokesman said: "The man still had the surfboard attached to his broken leg when he made it to shore and the pain must have been severe with the drag factor and weight of that pulling against the kite direction."
'Extreme' sport
The injured man, who has not been named, was taken to Southend General Hospital for treatment.
Simon Mudd, Essex Kite Surf Club chairman and UK co-ordinator for the British Kite Surfing Association, who also broke his leg in a recent mishap, insists the sport is safe, particularly in the Shoeburyness area.
