Using AutoTack in Wind Vane mode
Note: If you intend using AutoTack in Wind Vane mode, ensure the wind
vane has been centered accurately.
When AutoTack is used in Wind Vane mode, the boat turns through the
AutoTack angle and the autopilot will then trim the heading to mirror the
locked wind angle from the previous tack.
• To AutoTack to port:pressthe
-1 and -10 buttons together.
• To AutoTack to starboard:pressthe
+1 and +10 buttons together.
Figure 2-19: Using AutoTack
Note: If you have set the vessel type to SAIL BOAT, you can adjust the de-
fault AutoTack angle in Pilot Basic or Advanced calibration (see
Section 8, Chapter 5).
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 pilot 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.
