You select FU mode from the autopilot pop-up

Note:

If the autopilot pop-up is closed or if an alarm dialog is activated on the unit

controlling the autopilot in FU mode, the autopilot automatically changes to STBY mode.

Warning:

While in FU mode you cannot take manual control of the wheel.

AUTO mode (auto compass)

In AUTO mode the autopilot issues rudder commands required to steer the vessel
automatically on a set heading.

•

You select AUTO mode from the autopilot pop-up. When the mode is activated, the
autopilot selects the current boat heading as the set heading.

Changing set heading in AUTO mode

You adjust the set heading by using the rotary knob, the Port/Starboard arrow buttons in the
autopilot pop-up, or by selecting the Heading tile in the autopilot pop-up and then entering
the desired heading value.
An immediate heading change takes place. The new heading is maintained until a new
heading is set.

Heading capture

When the vessel is turning in AUTO mode, an instant reset of the mode activates the heading
capture function. This automatically cancels the turn, and the vessel continues on the
heading read from the compass the very moment you re-activated the mode.

Tacking in AUTO mode

Note:

The tack function is only available when the system is set up for boat type SAIL in the

Autopilot Commissioning dialog.

Tacking should only be performed into the wind and must be tried out in calm sea
conditions with light wind to find out how it works on your boat. Due to a wide range of
boat characteristics (from cruising to racing boats) the performance of the tack function may
vary from boat to boat.
Tacking in AUTO mode is different from tacking in WIND mode. In AUTO mode the tack angle
is fixed and as defined by the user. For more details, see

"Tacking - WIND mode"

on page 57.

You initiate the tack function from AUTO mode.
When tacking direction is selected the autopilot changes the current set course according to
the set fixed tacking angle.
You can interrupt the tack operation as long as the tack dialog is open by selecting the
opposite tacking direction. When interrupted the boat returns to the previous set heading.

NoDrift mode

NoDrift mode combines the autopilot and the positioning information from the GPS.
In NoDrift mode the vessel is steered along a calculated track line in a direction set by the
user. If the vessel's heading is drifting away from the original heading due to current and/or
wind, the vessel follows the line with a crab angle.

Turn the vessel to the desired heading

Activate the NoDrift mode. The autopilot draws an invisible bearing line based on current
heading from the boat’s position

Unlike in AUTO (compass) mode, the autopilot now uses the position information to
calculate the cross track error, and automatically keeps your track straight.
You use the port/starboard arrow panel buttons in the autopilot pop-up or the rotary knob
to reset the bearing line while in NoDrift mode.

Dodging

If you need to avoid an obstacle when using NoDrift mode, you can set the autopilot to STBY
and power steer or use the helm until the obstacle is passed.
