Although our primary auto-pilot is a Robertson AP, as a back-up we have an inexpensive Ray-Marine ST2000 Tiller Pilot that attaches to the wheel. For this we have a bracket that attaches to the wheel hub and the rim. Approximately 2/3rds of the distance between the hub and the rim--roughly level with the top of the seats in the cockpit--is a pin that is free to rotate with a small transverse hole that will accept the pin from the tiller-pilot. The stock length of the push-rod on the Pilot is about 2' but you can purchase extensions, if necessary. This arrangement will give our wheel about a 1/4 turn in each direction which, for our boat, is more than enough to maintain a steady course under most conditions. The tiller pilot is entirely self contained and merely needs power and has more than enough thrust to handle our boat given the advantage of the wheel.
