"So, a guy on a waterski, connected to a parachute, is considered SAILING?"
Yes...so what bothers you the most? A) The fact that he is going nearly twice as fast as a typical beach cat. 2)The fact that he is doing it for 10% of the cost of a new NACRA 20CF? C) The fact that all the gear it took to break the record would fit in the trunk of a sub compact car? D) All of the above.
