Auto Guidance Line Configurations
CAUTION
The Safe Depth and Safe Height settings influence how the
chartplotter calculates an Auto Guidance line. If an area has an
unknown water depth or an unknown obstacle height, the Auto
Guidance line is not calculated in that area. If an area at the
beginning or the end of an Auto Guidance line is shallower than
the safe water depth or lower than the safe obstacle height, the
Auto Guidance line is not calculated in that area. On the chart,
the course through those areas appears as a gray line. When
your boat enters one of those areas, a warning message
appears.
NOTE:
Auto Guidance is available with premium charts, in some
areas.
You can set the parameters the chartplotter uses when
calculating an Auto Guidance line.
Safe Depth
: Sets the minimum depth (chart depth datum) the
chartplotter uses when calculating an Auto Guidance line.
NOTE:
The minimum safe depth for the premium charts is 3
feet. If you enter a Safe Depth value of less than 3 feet, the
charts only use depths of 3 feet for Auto Guidance route
calculations.
Safe Height
: Sets the minimum height (chart height datum) of a
bridge that your boat can safely travel under.
Shoreline Distance
: Sets how close to the shore you want the
Auto Guidance line to be placed. The Auto Guidance line
may move if you change this setting while navigating. The
available values for this setting are relative, not absolute. To
ensure that the Auto Guidance line is placed the appropriate
distance from shore, you can assess the placement of the
Auto Guidance line using one or more familiar destinations
that require navigation through a narrow waterway (
Adjusting the Distance from Shore
The Shoreline Distance setting indicates how close to the shore
you want the Auto Guidance line to be placed. The Auto
Guidance line may move if you change this setting while
navigating. The available values for the Shoreline Distance
setting are relative, not absolute. To ensure the Auto Guidance
line is placed the appropriate distance from shore, you can
assess the placement of the Auto Guidance line using one or
more familiar destinations that require navigation through a
narrow waterway.

Auto Guidance maintains a wide clearance from obstacles in
open water, even if you set the Shoreline Distance setting to
Near or Nearest. As a result, the chartplotter may not
reposition the Auto Guidance line, unless the destination
selected requires navigation through a narrow waterway.

Tracks
