Calibrating the autopilot

Fernando,

Please click here to view a Forum thread in which I had addressed this subject, including how to perform rudder damping. As indicated within the referenced thread, rudder damping is used to limit the degree of S-ing. The Evolution autopilots are designed to learn the vessel's handling characteristics and will automatically determine a value for rudder damping, and as such, adjustment of this setting need not typically be performed by the user as well. If the rudder overshoots and has to drive back or starts to hunt back and forth, then rudder damping level may be increased to reduce this behavior

The Hard Over time is used to indicate the handling characteristics of the vessel's rudder and should only be adjusted to specify the hard over to hard over time.

Irrespective of the difficulty with installation some installations may require a rudder referenced to address handling characteristics of the vessel.
