Sensitivity & Rudder Adjustments
The AP4 autopilot has adjustments for setting heading sensitivity and rudder
response to customise the boat for optimum steering performance.
The control in the centre of the AP4 front panel adjusts both sensitivity and
rudder ratio. The centre position is usually suitable for most vessels, but
should the vessel's steering be sensitive or slow, adjustment maybe required.
In general, a vessel with fast turning rate will require a small rudder response
setting. A large, slow vessel may require a higher value for the rudder response.
This may also be adjusted according to speed - low speeds may require more
rudder angle for steering than high speeds.
