NoDrift mode
In NoDrift mode the vessel is steered along a calculated track line,
from present position and in a direction set by the user.
When the mode is activated, the autopilot will draw an invisible
track line based on current heading from the vessel's position. The
autopilot will now use the position information to calculate the
cross track distance, and automatically steer along the calculated
track.
Ú Note:
If the vessel is drifting away from the track line due to
current and/or wind (W), the vessel will follow the line with a
crab angle.
To change the set track line
• Select a port or starboard button
NAV mode
Warning:
NAV mode should only be used in open
waters. Navigation mode must not be used while
sailing, as course changes may result in unexpected
tacks or gybes.
Prior to entering NAV mode you must be navigating a route or
towards a waypoint.
In NAV mode the autopilot automatically steers the vessel to a
specific waypoint location, or along a pre-defined route. Position
information is used to change the course to steer to keep the vessel
on the track line to the destination waypoint.
Ú Note:
For information about navigation, refer to "Navigating" on
page 63.
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.
