When the SmartPilot is in Wind Vane mode it uses the wind angle as the primary heading ref-
erence. As changes in the true or apparent wind angle occur, it adjusts the locked heading to
maintain the original wind angle.
Selecting Wind Vane mode
You can select Wind Vane mode from either Standby or
Auto mode:
1. Steady the boat onto the required wind angle.
2. Press
MENU
, then use < and > to select Wind Vane
mode and lock the current wind angle. The display
shows the locked heading (e.g. 128°) and the wind
angle (e.g.
WIND 145P
indicates an wind angle of 145°
to port).
3. The SmartPilot will then adjust the boat’s heading to
maintain the locked wind angle.
Adjusting the locked wind angle
You can adjust the locked wind angle by using the
1
,
+1
,
10
and
+10
buttons to change
course. For example, to bear away by 10° when the boat is on a starboard tack:
•press
10
to turn the boat 10° to port – the locked wind angle and locked heading will both
change by 10°.
• the autopilot will then adjust the locked heading as required to maintain the new wind
angle.
Note: Because turning the boat affects the relationship between the true and apparent wind angles, you should only use this
method to make minor adjustments to the wind angle. For major changes, return to Standby mode, steer onto the new heading,
then reselect Wind Vane mode. Refer to the ST70 Autopilot Controller User Reference Guide for the procedure for changing
the wind reference between True and Apparent.
Leaving Wind Vane mode
You can leave Wind Vane mode by:
• pressing
AUTO
to return to Auto mode.
• pressing
STANDBY
to return to manual control.
Press ENTER to select.
