I had a random winter, boat out of water idea. I would like an auto pilot for the boat, but cant justify the cost. I mostly daysail, a lot of it singlehanded, I need an extra hand for keeping the boat on course for raising the mainsail and the asymmetrical, whisker pole, using the head, etc. My thought was to fabricate an emergency tiller to attach to the rudder post through the access port with an arm that faced towards stern. I could attach tiller pilot to pushpit and to rudder arm. My only concern is leverage on the tiller arm, havn,t measured yet but guessing 30 inches on the stock and the arm i can make adjustable. I will need a spare access port with a hole in it with a rubber sleeve to keep water out of bilge. Doesn't have to be water tight, but keep most of the heavy stuff out. I saw couple tiller pilots for sale for 150 bucks in good shape and could fabricate the tiller at a friends shop. Looking for reasons why this wont work? hat am I missing?
