On-Line Chart Viewer

Up-to-date charts you can view on the Internet.

The nautical chart is a fundamental tool of marine navigation. It shows water depths, obstructions, aids to navigation, channels, shoreline, and more – hopefully all the information mariners need to navigate safely.

NOAA’s 1,000-plus U.S. coastal and Great Lakes nautical charts are viewable here on-line. Each chart is up-to-date with the most recent Notices to Mariners. Use these on-line charts as a ready reference or planning tool. Use one of NOAA’s printed or digital charts on your voyage.
