NORVANE SELF STEERING WIND VANE
Stainless steel, servo-pendulum
Powerful, sturdy and reliable
The NORVANE works on a servo-pendulum system, which is generally accepted as being the most efficient means of self steering. It is completely mechanical, powered only by wind & water and uses the vessels’ existing steering system to steer the boat. It does not need any electricity therefore will not flatten your batteries. The NORVANE is strong and powerful and can steer the vessel, for extended periods, better than most helmsmen in all weather conditions; in fact, the harder it blows the better it works.
HOW IT WORKS
The NORVANE is easy to operate. It connects to the vessels steering system by means of lines running from the NORVANE unit to the vessels’ tiller or wheel. Once the sails are trimmed and the boat is balanced and set on the desired course, the NORVANE is engaged; when the boat wonders off course (or the apparent wind shifts) the slightest change in the apparent wind, plus the action on the servo-rudder by the water flowing past the hull, activates the NORVANE to return the boat back on track.
The wind blade follows the direction of the wind and will register even the slightest change. When there is a change in the wind direction, the foil is pushed to one side, forcing it to activate the gears to turn the servo-rudder. At the same time, the water flow over the servo-rudder will swing it up to one side or the other; this action pulls the lines connected to the steering, bringing the vessel back onto the set heading.

- Quick removal of unit from boat for storage.
- Overload protection in case of impact.

SPECIAL FEATURES
- SERVO-RUDDER - When not in use the servo-rudder can be tied up in a vertical position so that it is out of the way; or the entire unit can be removed for storage by simply undoing the holding bolt from each bracket leaving only the bracket.
- NO CONCEALED LINES. All moving parts are visible and easily accessible, even underway.
- OVERLOAD PROTECTION. Overload protection, in case of impact, is provided through a shear tube [break-a-way tube] on the servo-rudder shaft, and can easily be replaced even underway. A 3-links safety chain will prevent the loss of the rudder.
- EMERGENCY STEERING. The NORVANE has a built-in square socket drive to hold a tiller arm.
ADJUSTABLE COUNTER-WEIGHT The counter-weight which ensures proper balance, can easily and quickly be adjusted so as to fine tune to suit wind and water conditions. It can be adjusted by removing only one pin and one circular cotter.
COURSE SETTING 360º. All models have worm gear with half degree graduations on the dial. A line can be attached so that the course can be controlled with ease from the cockpit or any other positions on the deck.
To set the NORVANE, the course setting knob should be turned until the counterweight faces into the apparent wind, the lines are then fastened and as soon as the NORVANE is engaged it takes over the steering of the vessel
