At speeds above 20 kts that may be very dangerous , especially for waist harness users. At the movie Tony lands on his back, as his center of gravity is directly under the seat harness hook (He bend the legs, it helped a lot to keep his spine paralell to water surface).
With the waist harness the hook is way above your CoG.
Despite you bend the legs even harder, your ass tends to be much lower, touching the water first At :26.
This will start dynamic rotation of your body, increasing risk of whiplash when your head hits water at much higher speed.
I use a very light helmet since it happened to me for the first time and it helped a lot, also at higher speeds.
As I analyze now the movie, pushing the bar down to your thighs may help to keep your spine paralell to water, but we should do it automatically.
I wonder, how can we train it before the crash?
