Heading capture
When the vessel is turning in AUTO or NoDrift mode an instant press on the rotary knob
activates the heading capture feature. This will automatically cancel a turn, and the vessel will
continue on the heading read from the compass the very moment you pressed the knob.
Turn pattern steering
The autopilot includes automatic U-turn steering feature in AUTO and NoDrift modes, and
S-turn steering feature in AUTO mode.
U-turns
The U-Turn changes the current set course to be 180° in the opposite direction.
The turn rate is identical to default rate of turn (ROT) setting. This cannot be changed during
the turn.
After starting a U turn the dialog will be removed from the display.
Initiating a U-turn
1. Press the TURN key to display turn options
2. Select the U-Turn icon
3. Select the port or starboard turn direction in the turn dialog
Stopping the U-turn
You can at any time during a turn press the STBD key to return to standby mode and manual
steering.
S-turns
When activating the S-Turn pattern the boat will yaw around the main course.
You set the selected course change before the turn is started. During the turn you can alter
the course change and the turn radius.
The main course can be changed by turning the rotary knob.
¼ Note: The S-turns are only available in AUTO mode.
Activating the S-turn option
Before the S-turns mode can be applied it must be enabled in the turn settings thus making it
available in the turn settings dialog.
