I'm not denying he achieved a speed record, and I'm not saying there's anything wrong with kite-skiing; but it's stretching reality too far to call a waterski a boat, and a parachute a sail. Yes, he harnessed the power of the wind to propel himself at 54 knots, but call it what it is and establish that category's record. If you're talking sailing a boat at 50 knots, then l'Hydroptere found a way to do it; this guy did not.
