Operating hints for Wind Vane mode
•
Always trim your sails carefully to minimize the amount of standing helm.
•
Reef the headsail and mainsail a little early rather than too late.
•
In Wind Vane mode the SmartPilot will react to long-term wind shifts, but will not
correct for short-term changes such as gusts.
•
In gusty and unsteady inshore conditions, it is best to sail a few degrees further off
the wind so that changes in wind direction can be tolerated.
•
Avoid using Auto Tack in conditions where the wind may shift suddenly.
CAUTION: Allow time for course changes
CAUTION: When making major course changes, the trim on the boat may
change substantially. Due to this, the SmartPilot may take some time to
settle accurately onto the new course.
Preventing accidental gybes
The gybe inhibit feature stops the boat from performing an AutoTack away from the
wind – this will prevent accidental gybes. This feature can be disabled if required.
Note:
For the gybe inhibit feature to work, the SmartPilot needs suitable wind information.
With gybe inhibit on:
•
you will be able to perform an AutoTack through the wind.
•
the autopilot will prevent the boat from performing an AutoTack away from the
wind, to prevent accidental gybes.
With gybe inhibit off:
•
you can perform an AutoTack through or away from the wind.
Note:
Gybe inhibit is switched on as a default but can be disabled in User Calibration. See Gybe
Inhibit on page 15.
