WARNING: Jumping can be dangerous. Only jump when you have a clear safety zone 50m downwind and 30m upwind. Never jump in shallow water.
Once you learn your basic skills, you can try your first small jump. You may need to "unlearn" some of the reflexes you have developed while learning the basics. For example, you will be automatically sheeting the bar out to counter excess power in the kite. To jump, you need to sheet in to generate the power to get you airborne.
Your first jump - 1 to 3 meters
