8-2-20 Section 8: Autopilots
ST290 Instrument System Owner’s Handbook
Figure 2-17: Selecting Wind Vane mode
In Wind Vane mode:
• The display shows the locked heading, wind type and the wind angle.
• The autopilot adjusts the boat’s heading to maintain the locked wind
angle.
If the autopilot will not enter Wind Vane mode, it is not receiving wind
data. If this occurs, check the instrument and connections
Exiting Wind Vane mode
To exit Wind Vane mode, press either:
AUTO to return to Auto mode, or
STANDBY to steer manually in Standby mode.
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 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.
