The American shipping act requires that voyaging vessels have on board the appropriate and up-to-date chart of the area in which it is sailing. Other charts can be used for reference purposes, but only the NOAA charts (National Oceanic and Atmospheric Administration) are approved for navigation.
Official NOAA nautical charts of different scales including of Prince William Sound, the Gulf of Alaska, Kodiak Island and the Kenai Peninsula for marine navigation or map decoration!
