I found you don't want to keep the tiller in one place by using rope. Just as sailing with your hand on the tiller, you are always making small changes. The pressure on the tiller changes. That is why I use 2 bonjis on the windward side of the tiller and 1 on the lee and attached by rope on the tiller. If the bow starts to point up wind, the pressure on the tiller is less, so the double bonji will pull it and bring it down. Then the presure builds back on the tiller and counters the bonji. If set up correct, the tiller should be centered, adjust the bonjis to keep it centered. When I jump off the back of the boat, while holding on a rope, the bow would come up at little, pressure comes off the tiller, bonjis pull to straighten the boat. Even with me dragging, the boat just sailed on couse. Sent from my iPad
