whether the line safely avoids known obstacles, and whether the turns enable efcient travel.
Auto Guidance maintains a wide clearance from obstacles in open water, even if you set the Shoreline
Distance setting to  or . 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.

functionality of the Shoreline Distance setting.
