The autopilot has three ways of steering the boat, compass, GPS and wind. To select an
appropriate mode, see section 3-7. In wind mode, the autopilot steers the boat to a set angle to
the wind, called SWA (set wind angle).

7-3-1 Wind steering data

can be APP (apparent)
APP Apparent wind The apparent wind angle at the boat. P in front of the angle means the wind is from port, S means that the wind is
angle from starboard.
CTS Course to steer The course to steer to maintain the SWA (set wind angle).
Course error The difference between APP (wind angle) and SWA (set wind angle).
SWA Set wind angle The desired wind angle.
TRUE True wind angle The true wind angle at the boat. P in front of the angle means the wind is from port, S means that the wind is
from starboard.
Course error, 10° to starboard
CTS (intended autopilot course, to achieve
the SWA [set wind angle])
