bridge that your boat can safely travel under.

Shoreline Distance Auto Guidance Setting
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.
To set the distance from shore:
1. Dock your boat or drop anchor.
2. From the Home screen, select
Configure > Preferences >
Navigation > Auto Guidanc e > Shoreline Dist. > Normal .
3. From Home screen, select Where To? > Waypoints .
4. Select a waypoint for a destination that you have navigated to
previously.
5. Select Navigate To > Guide To .
