water depth or an unknown obstacle height, the Auto Guidance path is not
calculated in that area. If an area at the beginning or the end of an Auto
Guidance path is shallower than the Preferred Depth or lower than the
Vertical Clearance settings, the Auto Guidance path may not be calculated in
that area, depending on the map data. On the chart, the course through those
areas appears as a gray line or a magenta and gray striped line. When your
boat enters one of those areas, a warning message appears.
NOTE: Auto Guidance is available with premium charts, in some areas.
NOTE: Not all settings apply to all maps.
You can set the parameters the AQUAMAP uses when calculating an Auto
Guidance path.
Preferred Depth: Sets the minimum water depth, based on chart depth data,
that your boat can safely travel over.
Select Settings > Preferences > Navigation > Auto Guidance >
Preferred Depth and select a depth.
NOTE: The minimum water depth for the premium charts (made before
2016) is 3 feet. If you enter a value of less than 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.
Select Settings > Preferences > Navigation > Auto Guidance >
Vertical Clearance and enter a height.
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.
1 Dock your vessel or drop the anchor.
2 Select Settings > Preferences > Navigation > Auto Guidance >
Shoreline Distance > Normal.
3 Select a destination that you have navigated to previously.
4 Select Navigate To > Auto Guidance.
5 Review the placement of the Auto Guidance line, and determine whether
the line safely avoids known obstacles and the turns enable efficient
travel.
6 Select an option:
• If the placement of the Auto Guidance line is satisfactory, select MENU
> Navigation Options > Stop Navigation, and proceed to step 10.
• If the Auto Guidance line is too close to known obstacles, select
Settings > Preferences > Navigation > Auto Guidance > Shoreline
Distance > Far.
• If the turns in the Auto Guidance line are too wide, select Settings >
Preferences > Navigation > Auto Guidance > Shoreline Distance >
Near.
7 If you selected Near or Far in step 6, review the placement of the Auto
Guidance line, and determine whether the line safely avoids known
obstacles and the turns enable efficient travel.
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
