Hi George

We do downwind launches today in F3B, but not with captured hooks (but we slightly bend the hook upwards).
You built up line tension, turn the plane on knife edge after release and go downwind. In this part you only tack the winch to not use up to much line. Some stop completely pulling line for a short time. When you are beyond the pulley, the helper starts the winch again and you very gently start the climb upwind using rudder.

You can also circle tow with a non captured hook, you just need to make sure that you don't run out of line tension.

Todays winches have a ratchet/reverse stop (you can stop pulling in line and the drum is blocked). But what you have spooled on the drum you don't get back. The turnaround pulleys need another rotational degree of freedom to do crosswind/downwind launches.
