AutoTack Automatic function that determines how a boat tacks. When applied:
•
Outside of Wind Vane mode (standard AutoTack), the boat tacks by
a fixed angle between a port tack and a starboard tack. Default
AutoTack angle is100°.
• In Wind Vane mode, the tack angle relative to the wind on one tack
is mirrored on the other side of the wind on the next tack.
AutoTrim The AutoTrim setting determines the rate at which the autopilot applies
‘standing helm’ to correct for trim changes caused by varying wind load
on the boat.
AutoTurn Automatic function that determines how a boat turns to either port or
starboard. When applied, the boat turns through the AutoTurn angle.
Default 90°.

prevent the boat from yawing off course. Higher counter rudder
settings result in more rudder being applied.
dc Direct current.
EMC Electromagnetic Compatibility. When powered up, all electrical
equipment produces electromagnetic fields, which can cause adjacent
pieces of electrical equipment to interact with one another, and cause a
degradation in performance. Use the EMC guidelines in this book, to
ensure optimum EMC between equipment and minimize any
unwanted interactions.
