How to jump? Is all about timing to do a jump. You need the optimum condition and the right size kite depending on the wind strength.
Step 1: Get some speed by bear downwind
Step 2: Once you get enough speed, send your kite to 12 O'clock hard (or 11 O'clock) by pulling the bar with your back hand.
Step 3: Once you feel the kite pulling you up, quickly edge hard your board upwind.
Step 4: Moment you about to pull off from the water, kick your board towards back so that your board doesn't stick to the water upon lift off.
Step 5: Start to pull hard your bar with your front hand to send your kite forward. Keep pulling until you land. Otherwise, you will swing under the kite.
Step 6: Moment you start coming down, spot your landing. Keep your board flat and use your knees to absorb the impact. Don't try to lean.
Tips:
1. Do not look at the kite, use your motor senses and feel the kite.
2. The more aggressive you send your kite up (or back), the more you need to pull back with your front hand.
