Thoughts and Considerations
Added an autopilot to the tiller of an Islander 29'. Very satisfied with the results. Very easy to install. Bought a unit that "spec'ed" for a larger boat - hence, plenty of power in heavy seas. Also, if you're comparing them go for the smallest "peg to peg" time. I included the (wired) remote - great for walking around the deck to check sail trim, huddling under the dodger in rain and spray, and keeping control when visitors have filled the cockpit.
