correcting autopilot overshoot

[Chuck - Raymarine - Moderator]

Bob,

What is the length and manufacturer's specified displacement of the vessel?

Did you perform a Factory Reset, re-execute the Dockside Wizard, and then re-perform the deviation/vessel handling cruise following the R4 Evolution autopilot software update?

Within the system diagnostics of your autopilot, what is reported for the maximum deviation?

Did you confirm that the autopilot was fitted with a rudder reference transducer (examine the ACU's rudder terminals to determine whether something is connected to them)?

What model of drive unit has been installed?

What is the hard over to hard over time?

What is the arrival circle radius of your MFD configured to?

What is the cubic capacity of the vessel's steering ram?
