I use a kite quick release in my (elastic) safety leash which connects me during sailing to the cat. ( to a bar at the transom).
The hook is connected to my trapeze in front of my chest.

If I capsize, the leash can swing to the end of this bar, giving enough extra length if necessary. So I I'm not hung-up.

In any situation where it's necessary to free myself from the lease, I can do that quickly by shifting the yellow hose away from my chest.
The leash will then fall free from the hook.

Ofcourse I have thought of building this mechanism in my trapeze wire.
It can be done easily, but you have to shorten your wires accordingly.
