Each chart is up-to-date by NOAA with the most recent Notices to Mariners corrections. While you can use these online charts for reference or planning purposes, you should use NOAA's printed or digital charts to navigate with while underway.
CAUTION: Use official, full-scale NOAA nautical charts for real-world navigation whenever possible. These are available from authorized NOAA nautical chart sales agents. Screenshots of online charts such as these do not fulfill chart carriage requirements for regulated commercial vessels under Titles 33 and 46 of the Code of Federal Regulations.
