3.7 Using the SmartPilot with sail boats
Using Wind Vane mode
You can only select Wind Vane mode if the SmartPilot is receiving suitable SeaTalk
or NMEA wind direction information.
What is Wind Vane mode?
When the SmartPilot is in Wind Vane mode it uses the wind angle as the primary
heading reference. 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 an-
gles, 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.
True and apparent wind
SmartPilots can maintain a course relative to either an apparent or true wind angle
in Wind Vane mode
Press ENTER to select.
