First of all, we should not keep the kite at 12 o’clock. 12 o’clock or zenith should be only a passage point to go from one side of the wind window to the other or its used for jumping. The kite should mainly stay between 10 and 11 or 1 and 2 depending on the side you want to go to, It’s what I call the riding area.
So while keeping the kite steady with one hand on the riding area the student or rider should grab the closest foot-strap with is front hand and use his elbow to press down on the heel side tip of the board where the fin is, placing the board perpendicular to the lines and parallel to the kite. This way the kite is pulling you slowly and the board is pushed against your arm keeping it all secure, controlled and in place. After this, you should first lean away from the board and place the foot on the most distant foot strap. After you can press with your hand on the foot-strap, you are holding and put the remaining foot on the closest foot strap. During all of this, the kite should remain stable in the flying area between 10 and 11 or 1and 2.
This way you can have a controlled kite and board when learning to kitesurf, making it easy to get the board on your feet. This step comes after you already have learned to body drag with one hand and also with the board. So your kite control skills should be enough to allow you to not move the kite unintentionally.
That way keeping the kite stable with one had should be something that is already possible for you to do.
Learning to kitesurf is a sequence of steps, and this one is one of the ones I notice that more people struggle and get frustrated. Learn how to put the board on your feet correctly will make a significant impact on your learning progress. This method is not dependent on your physical ability, it instead relies on your kite control skills and helps you improve on them.
