I prefer a tiller. My I-28 has a wheel. It also has (had and still has) its original tiller. Mr. Perry designed a very well balanced boat. I replaced the wooden tiller with a short section of aluminum pipe and now have a tiller, too! It stands vertical over the rudder post and spins out of the way when not in use. After I have cleared the lobster pot danger zone I can relax and steer with one finger. It will allow me to add a Raymarine ST2000. I want to play with John Letcher's Self-Steering for Sailing Craft ideas, too.
Free! It was a piece of scrap I scrounged.
