As the title implies, these instruments display the wind speed and direction. The display may be on a meter face or it may be a digital readout.        

The wind speed and direction are relative to the ship. The ship’s speed and course must be taken into account to obtain the true wind speed and direction.

Many ships, including foreign flag ships, cooperate with the U.S. Weather Bureau by sending weather data to the bureau in intervals while at sea. This data consists of barometric pressure, wind speed, and direction, temperature, clouds, and of course own position.
