Go one step further and steer from the mast!
I used the following method on my Catalina 27. It's similar to Zephyrus's method but goes one step further. Run your line from the tiller, around the back of the starboard stanchion, then forward, outside the stanchions, around the front of your mast and back on the other side, around the port stanchion back to the tiller. The tiller connections are just tied loops that don't need to be too tight so you can slip them off quickly if necessary. Bungees aren't necessary due to the friction in the system and you can steer from the mast by pulling on the line in one direction or the other! You'll need to experiment a little to get the tension right so the friction has the right balance between ease of movement and holding the tiller in place. It takes a little practice at the mast to develop a feel as to which way to pull, but it works great once you do.
