Gary,
I should mention that Rick disagrees with me and my theory.

He says to heave to in a cat, you DO put the tiller all the way over to leeward. The jib is backed as in the other theories, and set the main according to how high you want the boat to ride in relation to the wind and waves.

I still think that having the tiller hard over is going to keep you from progressing forward and will result in too much leeway.

We don't have a boat to experiment with right now, so I guess it's up to you to do the testing and puckering.
