Going Upwind with a kite
To go upwind on a free sail system such as a windsurfer, the sailor move the sail backward to move the center of force behind the center of resistance of the board, fins and keel.
On a kitesurfing system, a kitesurfer holds the kite in his hands and his feet transfer the pull of the kite to the board; therefore the center of force is normally between his two feet. The kitesurfer can move this center of force slightly by transferring his weight to his front foot or his back foot. To go upwind on a kitesurfing system the kitesurfer has to move both the center of force and the center of resistance.
1. Move the center of force backward by transferring his weight more to the back foot. For a bidirectional kiteboard, this action is mandatory and for a directional kiteboard, it is optional.
2. Move the center of resistance forward by pressing the windward edge to put the board from 15 to 45 degrees to the water.
3. So the current way to go upwind on a kitesurf board is to "ride" on its windward edge. However, in theory, if the center of resistance of the board is between the kitesurfer's feet, he can ride the board flat and transfer the weight to his front foot to go downwind or back foot to go upwind.
- try to look to the direction you want to ride to, and make sure you also move your upper body facing that direction as well. This will force your hip to turn further as well, then you will go upwind better. So basically, don't look to your kite, but instead look to a point you want to head to. If you can, take the front hand of the bar and let it glide on the water, this way you will turn your head, shoulders and hip as well, leading for more upwind.
