The Aries Vane Gear works on the servo
pendulum system in which the vane operates a servo rudder which
can swing sideways. This sideways motion is transmitted to the
tiller or wheel by ropes and blocks. The Gear only has to develop
enough power to move the tiller or wheel to steer, which easily
obtained from the servo rudder through its length and leverage
in pulling the steering lines.
The Gear is suitable for virtually every
type of yacht up to 55ft L.O.A. The minimum sized vessel is usually
around 28ft. L.O.A due to the Gears mainframe weight of 50lb
being unacceptable on smaller boats unless they have broad stern
Fin keel/skeg rudder design yachts which
have inherent quick helm response do not cause any oversteer
problems with the Gear. The two mounting tubes coming from the
Gear can be bolted to the aft deck or transom using the standard
clamps, bolts and timber packing blocks.
