SPECIAL
FEATURES
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
360° course setting. 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.
NO CONCEALED LINES
The lines connecting the servo-arm to the wheel or tiller are not
concealed in any way and are therefore easily replaced. The rope
eye-lets, with multi-positions to suit your vessel are fixed
only once you are happy with the positions [not pre-welded at
the factory.] Two sheave blocks are provided with the NORVANE.
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 in position.
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 link safety chain will prevent
the loss of the rudder.
EMERGENCY STEERING
The NORVANE has a built-in square socket drive to hold the tiller
arm. (Optional extra)
All that is required to use the NORVANE to steer your boat in an
emergency is to:
1. Remove the wind blade
2. Free the pushrod and lash the servo-arm in a vertical position
3 Insert the tiller arm into the square socket drive and secure
in position with a pin & circular cotter.
WIND BLADES
The NORVANE comes with two wind blades, a large one for light winds
and a smaller one for strong winds.
These extra strong blades are made from an ultra-light, UV resistant
Polycarbonate material and have two struts for added strength.
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 wind blade 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 or other side; this
action pulls the lines connected to the steering, bringing the
vessel back on the set heading.
