These electronic charts are used with electronic charting software provided by commercial companies. They are not available in a standard graphics format.

These charts are page-size panels in booklet format that you can print at home.

For information on other charting products, such as traditional paper charts, print on demand charts, and U.S. Coast Pilots, see How to Obtain Charts.

Screen captures of the on-line viewable charts available here do NOT fulfill chart carriage requirements for regulated commercial vessels under Titles 33 and 46 of the Code of Federal Regulations.  Use official, full scale nautical charts for real-world navigation. 

Please submit comments to suggest improvements to the service, notify us if a chart image fails to display properly, or report a chart discrepancy.

Helpful Hint: Open the Catalog and Chart List in separate windows as it is convenient to go back and forth between the catalog and charts.
