Like I said before in my previous post(page 1), you can try to build in a kite safety release.
You just simply buy a socalled leash line (tether) and dismount with a little DIY the actual release mechanism from the leash line itself.

After that, with the same DIY, you mount a shakle on the free end and connect the mechanism to whatever line or wire you want.

After a number of accidents in the early beginning of the kitesport, manufacturers were pressed with their nose on the fact that there were real dangers in kiting.
So they searched for and invented several quick-release mechanisms. And in learning kiting its the first thing you learn to handle.

Surprisingly this isn't done in catsailing. On this forum I have spoken a lot of the risks and the measures which you can take. I always had the feeling that this was a bit in vain.

Hope that the original question from Jay in this thread gets a serious follow-up.

P.S.
Here's the design of a controllable release mechanism which I added for showing the basic principle. (I'm not sure if this build-in adjustment of the necessary handforce works though):
