Best inexpensive gadget I ever bought
I have the Davis tiller tamer on my Oday 23, and I love the thing. I put it in last year, and it makes single-handing a breeze. Its not an autopilot and if your boat has significant weather helm, it might not be right for you. but for 20-something bucks, its tough to go wrong. I mounted it on the underside of my curved tiller and put two cam cleats on the top edge of the transom to hold the control lines. the lines do not take up any appreciable space in the cockpit. Even if I'm with others, it frees my hand to eat, drink, etc. for short periods. On one nice day, I let it steer for about 15 minutes; held the course as well as I could have. there are lots of different models available if you don't like the Davis, including some I found on the internet made of brass and other fancy materials. Check the archives of this site for some ideas.
