2-6 How the unit measures wind
speed and angle
The masthead unit has a rotor with three wind cups
which spins as the wind moves past the boat. The
masthead unit measures how fast the wind cups are
spinning to calculate the wind speed.
The masthead unit has a vane which points in
the angle that the wind is coming from. The
masthead unit electronically senses the direction
the vane is pointing.
