AutoTack angle
Note: The AUTOTACK ANGLE function is only active if the vessel type is set
as SAIL BOAT.
The AutoTack angle is the angle through which the boat will turn when
you select an automatic tack.
Relative (Mirror) tacks
You can also set the AUTOTACK
ANGLEfunctiontoperformrelative
tacks.
When a relative tack is executed,
the boat turns so that the angle to
the wind is mirrored.
If you wish to use relative tacking,
set the AUTOTACK ANGLE parame-
ter to RELATIVE.
Note: When using AutoTack in
wind vane mode, your system will
automatically trim to the mirrored
angle having turned through the
set angle first.
