Reference Manual
Actual boat heading is 45°
CTS (course to steer, the intended autopilot course) 55°
Course error = 10°
Important:
• The autopilot cannot control the boat better than a helmsman. The autopilot is not intended for use in
extreme weather, in adverse conditions or near other boats, dangerous waters or land. In these conditions,
disengage the autopilot and steer manually.
• Never leave the helm unattended, keep a watch at all times and be ready to resume steering the
boat manually.
• Do not try to turn the rudder by hand when the autopilot is engaged.
• Local variations in magnetic field can affect the accuracy of the compass heading. Such variations are the
responsibility of the user.
7 Steering modes
The autopilot has three ways of steering the boat, compass, GPS and wind. To select an appropriate mode, see
section 3-7. In Compass mode, the autopilot steers the boat to a set course, called CTS (Course to steer).
