I have to agree with Dorothyinse that kiters will always help someone in distress although I do believe that if you were out on the water and someone needed help or rescuing that you would offer the same assistance, right?
Rescuing done with a kite does make it a tad easier though and this is why we all go out of our way to help fellow kiters and water users alike - In a way this helps to promote kiting too as there does seem to be a bad stigma attached to kiteboarding being identified as a dangerous sport and not safe for other beach users and bathers hence why spots are being closed to kiteboarding.
3x Cheers to the guy that rescued you!!
