4.7 Sea Trial
Caution ! The Sea Trial must always be performed in open waters at a
safe distance from other traffic.
The Sea-trial menu can only be accessed if the Dockside Settings
are completed and confirmed.
The seatrial settings are:
• Rudder zero adjust (To tell the autopilot the precise midships
position of the rudder)
• Minimum rudder
• Compass calibration (To automatically compensate for
onboard magnetic interference)
• Compass Offset (To compensate for a fixed offset (A-error) in
the final compass heading readout)
• Wind Offset (To compensate for a fixed mechanical offset of
the Wind vane)
• Wind Damping (To avoid flickering on the wind display)
• Depth offset (To compensate for the distance between the
depth transducer and the surface if required)
• Automatic tuning (A method of determining the steering
parameters)
• Transition speed (the speed at which you want a power boat to
change steering parameters)
• Init NAV (to set the response you prefer when steering onto a
track in NAV mode)
• Drive output adjust (See Dockside Rudder Test page 90.)
