Hi guys, I've reading this thread and it sounds interesting. I hope I can help a little so I thought of another setup for the T foils. So check out the attachment. This designs allows you to tune the exact force that you want to rotate the wing by means of a metal spring. Another advantage is that you can add this setup to almost any existing rudder by making a cassette that screws on to the bottom of the rudder tip, cassette containing the spring mechanism and the wing... When the boat floats level the wing will realign and the spring will push the small rod into the notch of the wing pivot and secure it. You think this design has a chance of working properly ?
