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 chartplotter 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. 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. 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, page 21). 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 result, the chartplotter may not reposition the Auto Guidance line, unless the destination selected requires navigation through a narrow waterway. 8 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 > Farthest. • If the turns in the Auto Guidance line are too wide, select Settings > Preferences > Navigation > Auto Guidance > Shoreline Distance > Nearest. 9 If you selected Nearest or Farthest in step 8, 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 result, the chartplotter may not reposition the Auto Guidance line, unless the destination selected requires navigation through a narrow waterway. 10Repeat steps 3 through 9 at least once more, using a different destination each time, until you are familiar with the functionality of the Shoreline Distance setting.
