Adjusting response Control
The Tillerpilot will apply adjustments to the tiller, in order to
compensate for heading variations, the amount of movement
being proportional to the heading error detected by the compass
unit. The amount of movement is set by the Response Control
(sometimes referred to as the rudder ratio).
The Response Control setting can be likened to driving a motor
vehicle – at high speeds, very little wheel movement is necessary
to steer the vehicle (LOW Response). When driving at slow speeds,
more wheel movement is necessary (HIGH Response).
The figure shows;
D
- A:
Response Control too low – the vessel takes a long time to
return to the correct heading.
- B:
The ideal setting, where errors are quickly corrected
- C:
Illustrates the effects of setting the Response Control too high,
which causes the vessel to oscillate around the correct heading
-
Excessive Response (d) creates a tendency to instability of course,
leading to increasing error.
When Response Control is selected, the
repeated sequence of beeps will be heard. The number of flashes
and beeps in the sequence indicates the level of the Response
Control setting.

Adjusting Seastate
In heavy seas, more variations in heading will be detected. If
the Tillerpilot tried to respond to all of these errors, it would be
overworked, causing unnecessary strain to the unit and excessive
drain on the batteries. Instead, it continuously monitors the
corrections applied over the course of a voyage and allows a
"dead band" within which the boat can go off course without
constant corrections being made. The size of the dead band is
normally automatically adjusted by the Tillerpilot to give the best
compromise between course holding and battery consumption,
but it can be turned off if required, giving a fixed deadband:
