Body Position
Balance is the key in this sport, as well as in other sports. Balance is achieved when your body position on your ski is evenly distributed. Balance is comfortable when you can remain in the same position for an extended amount of time. A good position allows the body weight to be supported on the inside balls of your feet, which helps to keep the knees slightly bent and together. Your torso should be directly over the feet with the chest out, head up, and shoulders back. Once you can maintain this position, the ability to cross the wakes should be confident.
Water Ski Position
To start with, your ski and body must point towards the direction you want to go. Face the wake head on. Make sure you force your lower body and the ski through the wakes with both feet first. However, having your feet go first does not necessarily mean you are to lean back with your upper body. Keep your weight on the balls of your feet and not your heels.
Your ultimate goal is to have your ski go through the water on its edge, but that will come as you practice going through the wake at sharper angles and at faster speeds. Your ski goes through the water much faster on its edge than when it is flat on the water.
Remember to take it slow in the beginning, and as your confidence level increases, so will your ability to tackle the wakes.
