A small “arrow” symbol, in the correct direction, appears in the “Gybe ?” prompt, as a
reminder of which button to push.
• The autopilot will not do the Gybe if you press the wrong “direction” button, but
instead just restore the normal WIND or WIND-Points display.
5) The autopilot will slowly steer the boat to the Gybe Hold Point on the opposite tack.
Once the Gybe manoeuvre is completed, the Commanded Wind Angle can be adjusted
as desired, and you can let out & trim the sails as required.
 Caution! Be alert – avoid the swinging boom!
• During the Gybe, the autopilot automatically adjusts its steering parameters (Rudder

• The autopilot will only gybe the boat if the actual wind angle, at the time the
