Using the Autopilot | Zeus Touch Operator Manual
NoDrift mode
This mode combines the Autopilot and the positioning information
from the GPS.
When NoDrift is activated, the Autopilot will draw an invisible bearing
line based on current heading from the boat’s position.
Unlike in AUTO (compass) mode the Autopilot will now use
the position information to calculate the cross track error, and
automatically keep your track straight.
You can use the port and starboard indicators 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 press 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 don’t respond the dialog will disappear and
the Autopilot will go to NoDrift mode with current
heading as set bearing line.
If your dodging maneuver takes more than 60 seconds, the Autopilot will remain in Standby
mode.
Navigating with the Zeus Touch
You can use the Autopilot feature to automatically steer the boat to
a specific waypoint location, or through a route of waypoints. The
position information received from the GPS will be used to change
the course to steer to keep the boat on the track line and direct to the
destination waypoint.
To obtain satisfactory navigation steering, the Zeus Touch must have
valid position input. Autosteering must be tested and determined
satisfactory prior to entering the NAV mode:
You can start navigation from any panel by pressing the GO TO / PAGES key. The go to cursor
option will only be available when the cursor is active on a Chart, Radar or Echosounder
panel. For more information about navigating with the Zeus Touch refer to “Navigating with
the Zeus Touch” on page 26.
You can also start navigating from the Autopilot menu.
When the Navigation mode is initiated, the Autopilot will automatically keep the vessel on
the leg. When your vessel reaches the arrival circle for a waypoint, the Autopilot will give an
audible warning and display an alert screen with the new course information.
If the required course change to the next waypoint is less than the Navigation change limit,
the Autopilot will automatically change the course. If the required course change to next
waypoint in a route is more than the set limit, you are prompted to verify that the upcoming
course change is acceptable.
¼ Note: For more information about navigation parameters and how to navigate with the
Zeus Touch, refer to “Navigating with the Zeus Touch” on page 26.
Warning: Navigational steering should only be used in open waters.
When selecting NAV mode, the Autopilot maintains the current set
course and prompts the user to accept the course change towards the
destination waypoint.
