3 feet, the charts only use depths of 3 feet for Auto Guidance
path calculations.
Vertical Clearance
: Sets the minimum height of a bridge or
obstacle, based on chart data, that your boat can safely
travel under.
Shoreline Distance
: Sets how close to the shore you want the
Auto Guidance path to be placed. The Auto Guidance path
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 path 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.
