9. If you selected
Farthest
or
Nearest
in step 8, review the placement of the Auto Guidance line.
Determine whether the line safely avoids known obstacles, and whether 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 result, the chartplotter may not reposition the
Auto Guidance line, unless the destination selected in step 3 requires navigation through a narrow
waterway.

with the functionality of the Shoreline Distance setting.
