Wind Vane Design Details
The Hebridean is a servo-pendulum wind vane. The vane detects a change in wind
direction when the boat is off course. The flow of water provides the power to
steer the boat.
With the boat off course the vane deflects, rotating the pendulum in
the water. Because of the flow, the pendulum swings to the side pulling lines to
the tiller (or wheel) correcting course.
As the boat approaches its correct heading the wind vane pulls the tiller back to where it was preventing it from over-steering. The vane is therefore "damped".
Changing course is done manually at the wind vane, or remotely (as provided in the optional extra kit) by pulling a rope from the comfort of the cockpit.
