1.6.7 STEERING LINES AND TILLER STEERING
1.6.7.1 POSITIONING THE TILLER FITTING
• Tiller fitting 010 should be mounted about 65% of
the way along the tiller, measuring from the rear
(e.g. if your tiller is 100 cm/40 in long, the fitting
should be about 65 cm/26 in from the aft end).
• Moving the tiller fitting further forward increases
leverage but reduces the angle through which your
PACIFIC LIGHT can turn the rudder.
• Moving the tiller fitting aft increases this angle but
reduces leverage.
• NOTE: it is impossible to have more leverage AND
more movement at the same time!
• A servo-pendulum system with automatic yaw
damping like the PACIFIC LIGHT is designed
to operate with an average steering line travel
between the system and main rudder of 20-25
cm/8-10 in.
1.6.7.2 POSITIONING THE RING ON THE
PENDULUM ARM
• Moving the ring up the arm (away from the axle)
increases travel but reduces transmission force.
• Moving the ring down the arm (towards the axle)
increases transmission force but reduces travel.
• See 2.2.6.2 Determining the Ideal Settings.
1.6.7.3 STEERING LINE BLOCKS
• The first pair of blocks should be mounted on or
outside the pushpit as far aft as possible.
• The other pair should be mounted on the cockpit
coaming slightly aft of the tiller fitting.
• Tie the steering lines to the ring 315 on the
pendulum arm.
• Lead them forward to the tiller through the two sets
of blocks.
• Attach the chain section where the steering lines
approach the tiller fitting.
1.6.7.4 LINE TENSION
• The lines must be neither too slack nor too tight;
either will impair steering.
• The steering lines should be rigged such that
engaging the chain in the tiller fitting sets them to
their ideal working tension.
• IDEAL TENSION: no slack, no strain.
1.6.7.5 CENTRING THE TILLER AND THE CHAIN
• The system and tiller can be centred with respect to
each other (e.g. to compensate for weather helm as
wind and sea conditions change) by adjusting the
chain at the tiller fitting.
• Assembly sequence: line/shackle/chain/2 snap
shackles/line.
