Configuring the Chartplotter

auto guidance—set the automatic guidance parameters:

Safe depth—set the minimum depth (chart depth datum) to 

allow when calculating an automatic guidance path. A safe depth 

of less than one meter is not allowed when using automatic 

guidance.
Safe Height—set the minimum height (chart height datum) of a 

bridge that your boat can safely travel under.
Shoreline distance—set the safe distance for your boat from the 

shore: Nearest, Near, Normal, far, or farthest.

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 (Nearest, 

Near, Normal, far, or farthest) are relative, not absolute. To 

ensure that the auto-guidance line is placed an 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.
