ST70 Pilot Controller Reference Guide
The default setting is apparent wind. If required, you can change this to true wind in
User Calibration. See
Wind Selection
on
page 16
.
WindTrim
In Wind Vane mode the SmartPilot uses WindTrim to eliminate the effects of
turbulence and short term wind variations. This provides smooth and precise
performance with minimal power consumption. You can adjust the wind response
(WindTrim) level in User Calibration to control how quickly the SmartPilot responds
to changes in the wind direction. Higher wind trim settings will result in a pilot that is
more responsive to wind changes. See
Wind Trim
on
page 16
.
Dodging an obstacle in Wind Vane mode
In Wind Vane mode you still have full control from the keypad. You can make a
dodge maneuver by using the course change buttons (
-1
,
+1
,
-10
or
+10
) to select
the desired course change.
After you have avoided the hazard, you can cancel the dodge course change by
making an equal course change in the opposite direction.
Wind Shift warning
If the autopilot detects a wind shift of more than 15° it will sound the wind shift
warning and display the
WIND SHIFT
message:
•
To cancel the warning, and retain the existing wind angle and new heading, press
CANCEL
.
•
Alternatively, to cancel the warning and return to the previous heading:
•
adjust the locked wind angle using the
-1
,
+1
,
-10
and
+10
buttons.
•
press
STANDBY
to return to hand steering, steer onto the required heading,
and press
CANCEL
to return to Wind Vane mode with the new wind angle.
Using AutoTack in Wind Vane mode
Note:
If you use the AutoTack function in Wind Vane mode, make sure the wind vane has been
centered accurately.
The SmartPilot has a built in automatic tack facility (AutoTack) that turns the boat
through a specified angle (default is 100°) in the required direction.
•
To AutoTack to port: press the
-1
and
-10
buttons together.
•
To AutoTack to starboard: press the
+1
and
+10
buttons together.
You can adjust the default AutoTack angle in User Calibration. See
Auto Tack Angle
on
page 15
.
You can also use the menu button to select and execute the autotack option.
When you Auto Tack in Wind Vane mode, the boat turns through the Auto Tack
angle. The SmartPilot will then trim the heading to mirror the locked wind angle
from the previous tack.
