When you raise the jib and hook the hook to the ring you pull the jib back down slowly to hook it. To release it, you yank up and then down quickly. As you yank up the ring will go up slightly, then yank down quickly before the hook can attach back to the ring. You use one quick up and down motion, maybe like milking a cow? This is the same system as on my Prindle 19. I hope this makes sense to you.
