Re: How to turn a hydrofoil - and what is YAW ?

So much said… Trying to compress
To make the technique more pure, think of an kbhf without the kite, just like a surfboardhydrofoil riding on flat water. With a kite you could somewhat cheat a little bit
First: (if there`s) No roll, (there will be) no turn without crashing.
Second: the roll is initiated by the yawing/twisting of the riders body. Important note: on the water your feet don’t have a stable anchor, so if your upper body is yawed/twisted clockwise, then your lower body is twisted anticlockwise (actio = reactio)
Third: Try to imagine how the riders center of gravity (hip/belly button) is travelling in a straight line and by twisting his body the mast/strut points out of the direction your body is travelling. Thus the mast/strut is led sideways underneath (!) your body. This happens in a very tiny fraction of a second. You are starting to “fall” sideways. To prevent the total “fall” or crash you have to twist a little bit backwards …..
Finally: on a kbhf the mast/strut acts like a rudder. Mast/strut is almost as effective sideways as the wings act like “rudders” for the pitch.
Countersteering initiates the turn. Not more, not less….. Is valid for so many sports…. (skiing, snowboarding, unicycling etc.) You just don’t feel it…………………….
