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, refer to
"Tacking in WIND mode"
on page 87.
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.
1.
Turn the vessel to the desired heading
2.
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 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.
If you return to NoDrift mode within 60 seconds you can select to
continue on previous set bearing line.
If you do not respond, the dialog disappears and the autopilot goes
to NoDrift mode with current heading as set bearing line.
