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

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.
