1.3.2 BAD AIR AND THE WINDVANE
 • Thewindvaneshouldnotsubjecttodisturbed
airflows in its working position.
NO PROBLEM
 • Badairfromasprayhood:thesprayhoodis
normally far enough from the stern not to be a
problem.
 • Badairarounddavits
 • Badairfromthesuperstructure
 • Badairoffthemainsail(sloop/cutter)
 • Badaircausedbypeopleinthecockpit
PROBLEM
 • Badairoffthemizzensail
 • Badaircausedbyanoutboardmotoronthe
pushpit
 • Badaircausedbyfenders/liferaftonthepushpit
1.3.3 PENDULUM RUDDER AND MAIN RUDDER
 • Thependulumrudderisusedsimplytogenerate
hydrodynamic force; since it does not steer the boat
directly, is ok for it to be close behind the trailing
edge of the main rudder.
 • Thependulumruddermoveslaterallyinoperation.
 • Turbulencecausedbythemainrudderdoesnot
interfere with the operation of the pendulum rudder.
1.3.4 ON LAND OR IN THE WATER?
 • YoucanfityourWINDPILOTwiththeboatashore
or afloat: it doesn’t really matter, as all the holes are
above the waterline.
 • Buttheheightabovethewaterlineforinstallationis
easier to find with the boat in the water.
1.4 INSTALLATION: QUICK GUIDE
1.4.1 THE FIVE CRITERIA
1 Installation height: mounting bolt 430 for the
pendulum rudder blade 440 should be 5-10 cm/2-4
in above the water (static waterline).
2 Overhanging/traditional sterns: does ring 315 on
the pendulum arm 300 swing clear of the top of
the transom/pushpit when the pendulum rudder is
raised?
3 Forward-raked/sugar-scoop sterns: does pendulum
rudder shaft 400 swing clear of the bottom/
aftermost edge of the transom?
4 Start by fastening the mounting bracket in place
with just one bolt. Then align the bracket, mark
where the remaining holes should be and predrill
them with the 9 mm bit. Now drill out the holes with
the 10.5 mm bit and complete installation of the
mounting bracket.
5 Align the system. Windvane shaft 140 must be
vertical!
