How does a wind vane self-steering work?
Self-steering gear achieves this by presenting a vane directly into the wind. When the wind acts on either side of this vane, it tips, transferring this action through the mechanism below to either a rudder or a servo pendulum which acts on the main rudder, altering the boat’s course.

How does a sailboat wind vane work?
The wind vane senses the wind and the movement of the vane turns the little rudder in the water, little rudder wants to straighten back out due to the water pressure on it and this straightening force, via some rope and pulleys, is transmitted to the wheel or rudder on the boat, and the boat is steered back on course.
