automatic sail instructor

I designed this automatic sail instructor, that beginners can learn the wind courses and how to set their sails correctly in a fun way. f you turn the boat, the sail adjusts itself automatically to right position. I know that the sail setting depends on the boat so the sail instructor is not really accurate. You dont need any additional parts to put it together. Its only important that the small gear and the big gear are on the top half und the two gears with the same diameter on the bottom (see pictures above). Note: I havent written any courses on the rotating disc so that you can add your own courses in your language.
