I found 2 other interesting thing you can do with a tiller.

Downwind in light air, you can keep your weight forward and over rotate your mast with your foot. (Is it legal to put a foot rest on the mast? I have an old over rotation plate from a A Class, that would be just perfect to rest my foot on.)

When tacking you can move aft to tack, then slide forward and use your foot to help your mast rotate over to the new side. Seems to help you get up to speed a little better.
