Wind vane steering

Prior to entering WIND mode the autopilot system should be
operating in AUTO, with valid input from the selected wind
transducer. The WIND mode is an alternative function to the
NAV mode and it is only available if the system has been set up
for SAIL-boat in the Installation Menu, and NAV/WIND source
is set to WIND under the USER SETUP menu. (Ref. to page 33).
WIND function can only operate when reaching as it is necessary
to have a stable apparent wind. The sails should be trimmed so
that the autopilot can easily steer the boat in AUTO mode and the
wind transducer must give a stable signal.
Enter the WIND mode by pressing the NAV/SETUP button.
First press
The pilot will read the apparent wind angle at the moment the
WIND function is selected and enter it as the set apparent wind
angle. From that point the pilot will change the course to
maintain this apparent wind angle as the wind direction may
change.
If the cumulative shift of the apparent wind exceeds 15° from the
Note !
value at the time the WIND mode was selected, a WIND SHIFT
alarm will sound.
The display will show the set apparent wind angle. Adjustments
to this set angle can be done by using PORT or STBD button or
the rotary course knob.
When pressing the NAV/SETUP button a second time the
display presents current heading and rudder angle.
