They turn when you make a twisting motion only.
Posting this, as it seems that we are some who disagree a lot about this very topic ?
My statement is, that you dont turn a hydrofoil by putting pressure on your toes or heels (or leaning forwards/backwards which is the same).
You turn a hydrofoil by twisting, giving the yaw motion that turns it (making it curve/carve)
I am quite sure of this actually, but might be proven wrong and open for this to happen.

Ok Peter, I will attempt to prove you wrong only because of your above statement, respectfully!
And hopefully to help others understand my thoughts on turning a kiteboardhydrofoil.
I post this photo to help prove my point.
It is extreamly clear to me that when I do a flying turns in this stance that I change foot pressure and the same goes when you do any turn in any stance.
I like you am open for dispute in the sake of learning but I am sure of this.
You need to put the kite where it will pull you thru the turn, at least in a jibe, a tack is a little different.
I feel I turn the kite up or down and wait until it starts to pull in the other direction then APPLY foot pressure on the down wind rail for a jibe and carve thru the turn.
Of course there is different timing for different wind speeds and turn radius.
I feel strongly that the turn happens when the STRUT, not MAST (see wikipedia for definition)
passes thru the vertical to arrive in the oppsit angle after the turn.
There must be a time when the strut is vertical and twisting alone can never make this happen.
The only way for this to happen is by applying weight on the rails to bring it up to vertical!
Twisting when not appling rail pressure will do very little to make a turn.
I believe the twisting to bring yaw rotation may play a role but a small one, and now that I think about it very little.
I will pay close attention to this my next session.

By the way for anyone wanting to find the center of lift on any foil, flying toes forward will quickly narrow it down!
So what do you or anyone else think?
