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.)

Select Seatrial by pressing the STBD button and confirm by rotating the course knob clock-wise.
