NAV mode options
While in NAV mode the following buttons are available in the autopilot controller:
Restart
Restarts the navigation from the vessel's current position.
Skip
Skips the active waypoint and steers towards the next waypoint. This option is only available
when navigating a route with more than one waypoint between the vessel position and the
end of the route.
Cancel
Cancels active navigation and deselects the current route or waypoint navigation. The
autopilot is switched to heading hold mode, steering the vessel on the heading that was
active when the cancel button was selected.
Ú Note:
This is different from selecting standby which does not stop current navigation.
Turning in NAV mode
When the vessel reaches a waypoint, the autopilot will give an audible warning and display a
dialog with the new course information.
There is a limit for the allowed automatic course change to next waypoint in a route:
• If the required course change to the next waypoint is less than the course change limit,
the autopilot will automatically change the course
• If the required course change to next waypoint is more than the set limit, you are
prompted to verify that the upcoming course change is acceptable. If the turn is not
accepted, the vessel will continue with the current set heading.
The course change limit setting depends on the autopilot computer. Refer to the autopilot
computer documentation.
Wind mode
Ú Note:
Wind mode is only available when the boat type is set to Sail. It is not possible to
activate wind mode if wind information is missing.
In wind mode the autopilot captures the current wind angle as steering reference, and
adjusts the heading of the boat to maintain this wind angle.
The autopilot will keep the boat on the set wind angle until a new wind angle is set.
Warning:
In wind mode the autopilot steers to the apparent or true wind
angle and not to a compass heading. Any wind shift could result in the
vessel steering on an undesired course.
To change the set wind reference angle
• Select a port or starboard button
• With the autopilot controller active, turn the rotary knob
An immediate change of wind reference angle takes place.
Tacking and gybing in wind mode
The tack/gybe option in wind mode mirrors the set wind angle on the opposite tack.
Tacking and gybing in wind mode can be performed when sailing with apparent or true
wind as the reference. In either case the true wind angle must be less than 90° (tacking) and
more than 120° (gybing).
The rate of turn during the tack/gybe is set by the tack time in the autopilot settings dialog.
Refer to "Autopilot settings" on page 103.
To initiate a tack or gybe:
