Ouch! Kiteboarders collide at speed while surfing in opposite directions off beach in Massachusetts
This man's kitesurfing session didn't go as flawlessly as he had hoped it would.
Filmed at Horseneck Beach, on the Atlantic coast about an hour south of Boston, USA, this video features Jeremy Allen riding the waves under the glaring light of the sun.
Just when it starts looking like nothing could go wrong, another kite appears out of the blue, towing another kitesurfer, who runs right into Jeremy and knocks him into the water.
The filmer said: "Well, kitesurfing is all fun and games until it isn't. I bet you all this guy was like, 'let's see how close I can get before I jump over this guy.' It is a great idea until you hit some chop and aren't able to hold the edge and you end up hucking your board at the guy."
