2.8 Automatic Steering
When AUTO mode is selected, the AP25 automatically picks the
current boat heading as the set course and maintains the
simultaneous rudder angle. This gives a bumpless transfer at the
mode change.

The AP25 will keep the boat on the set course until a new mode
is selected or a new course is set with the course knob or the
PORT or STBD buttons. One revolution of the course knob
equals a 45° course change.

Note ! On power boats it is possible in the User Setup menu to set the
buttons to change the course by 10° per press (see page
255).
Once the course is changed to a new set course, the boat will
automatically turn to the new heading and continue to steer
straight.
Heading capture
When in AUTO or NoDrift modes this feature allows you to
automatically cancel the turn you are in by an instant press on
the AUTO or NAV button (NoDrift). The autopilot will
counteract the turn and the boat will continue straight ahead on
the heading read from the compass the very moment you pressed
the AUTO or NAV (NoDrift) button.
