Get Funky, i've found the following method works for me every time.
1. Hook your chicken loop back onto your harness.
2. Depower your kite by pulling on the strap. This will reduce the tension on the back lines and allow the kite to roll onto its back easier.
3. Swim towards the kite until it rolls over. Stop as soon as it rolls
over because if you let the lines go slack the kite can turn inside out.
4. You will normally find that at this stage the kite will automatically start to go either left or right but often wont go around to the edge of the window. Whichever way the kite is facing, grab the corresponding, middle(front), line. ie. kite facing left therefore grab left front line. Pull the line towards you about a foot and simply keep tension on it until the kite comes around to the edge of the window.
In light conditions you may find that it takes a short amount of time for the kite to start moving around but if you keep the tension on it and maybe even pull slightly more line towards you it will work.
Hope this helps.
