Ok, I know I am going to get a hard time about this, but its the only pic I have of this. Yes, I have a pink T2. It was cheap and I needed a 14M (Heckle away)
Anyway, once we have the kite in the water, we often D ring the chicken loop to the ski rope point. This works well for waiting on better winds and just taking a break. One warning about doing this is that you want to make sure you have the anchor, boat, then kite all lined up downwind. We have had some issues doing this both when the boat comes un-anchored, or the boat drifts crosswind due to currents. It is all manageable as long as you keep an eye on things.
It is fairly easy to launch and fly just sitting on the back of the boat if the wind isn't too gusty, and for lessons, it is easier to swap the kite from one person to another out of the water (I don't teach, but we often switch the kite one person to another while it is aloft). I have even launched and flown the kite with the chicken loop attached to the boat with no problems (just to see if I could)
I imagine we will all get a good look at how a kite school does this once Nico posts his video. He has given me some good advice in previous posts and I look forward to seeing his system. What I took from his advice was that simpler is better (no need for gadgets) and that has proved to be true using various methods to get the kite and lines in the water.
