quoted from Mary "The version I like best is using one piece of bungie, the center of which is tied at the center of the aft beam. And each end of that bungie has a hook on it. (Just a regular, open hook.) When not in use, the hooks are hooked onto the aft lacing of my tramp, one at each side. Since I have one hook on each side of the boat, if I need to park on starboard, for instance, I just grab the hook on the starboard side and put the bungee around the starboard tiller arm at the joint with the crossbar, and hook it to itself."
I tried this out a couple of days ago and it worked perfectly, allowing me to eat my sandwiches on the water! Thank you Mary! It cost me nothing more than a couple of plastic hooks. I had the bungee lying around, precisely the right length. I do need to backwind the jib though and have the traveller out at 60% or more, or the boat will still tack (no waves). Just goes to show how much more powerful a mainsail is, compared to those puny rudders (esp. at low speed).
