only in class 3 to 1 Tornado's

That is just the difference between Macquarie and the kiters. The kiters basically dependent on wind speeds on a par with their top speed while the boats manage to outsail the windspeed by a factor 2 to 2.5.

The problem I see with the kites is that any suicidal fool can break the speed record by stringing himself to an extremely large parachute and hop for 60 knots winds. I know the kiters are a little bit more refined then that but only by a little.
