Most common mistake people make is over sheeting the kite when coming down a wave as the apparent drags around. As you come to the bottom and the boat slows down, the apparent will move aft. We all know what over sheeting does to a cat (drive the bows under)
Easing the kite as you get to the base of the wave and the boat begins to slow, will allow the shoulders (top of the kite) to lift in the kite creating more lift from the kite (lifting the bows). You can then head up as you are climbing the wave and power over the top....... Then repeat. A lot of sheet work required by the crew. Also smooth steering from the skipper and getting both skipper and crew in sync with each other. Practice, practice, practice.

Same goes when you encounter a smallish rouge wave in fairly flat water...... Or when you get hit by a big gust. A good ease not only opens up the kite, but the kite changes shape developing larger shoulders. Look at the shoulders on a skiff kite. They develop bucket loads of lift.

See below how the kite takes on such a different shape when eased.
