The word vane comes from the Old English word fana, meaning "flag". A cockerel is a traditional figure used as a vane placed on top of the cardinal directions.
Mechanical or "wind vane" self-steering started out as a way to keep model sail boats on course.Before the advent of radio control, model yacht racing (started before WW1) was typically contested on long narrow ponds, and the number of stops along the banks was counted as a penalty in the final result.

[1] The tail fin (or wind vane) is commonly used for small wind turbines since it offers a low cost and reliable solution. It is however unable to cope with the high moments required to yaw the nacelle ...
An anemoscope is a device designed to show the direction of the wind, or to indicate a change of wind direction . The name is usually applied to an apparatus consisting of a wind vane above, connecting to a building below by some kind of coupling, and with a dial or index with pointers to show the direction and changes of the wind.
Furthermore, since the wind varies in direction and the axis has to follow its changes, a wind vane or some other contrivance to fulfill the same purpose must be employed. A vane anemometer thus combines a propeller and a tail on the same axis to obtain accurate and precise wind speed and direction measurements from the same instrument. [3]

Wind sock for measuring general wind speed and wind direction; Wind vane, also called a weather vane or a weathercock: it shows which way the wind is blowing. Evaporation pan for measuring ...
