6 Wind steering mode
The G-PILOT 3100 has three ways of steering the boat, compass, GPS and wind. To select an
appropriate mode, see section 2-4. In wind mode, the G-PILOT steers the boat to a set angle to
the wind, called SWA (set wind angle).
6-1 Wind steering data
Course error, 10° to starboard
CTS (intended autopilot course, to
achieve the SWA [set wind angle])
SWA (set wind angle), 45°
can be APP (apparent)
APP Apparent wind angle 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 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
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.
