Bowditch's New American Practical Navigator, 1833

The New American Practical Navigator has been the navigator's bible for two hundred years, since its first publication in 1802. It was originally published by Edmund March Blunt and then by his sons. After the Civil War, the Blunts sold copyright to the U.S. Government, and it has since been a publication of the Hydrographic Office, now part of NOAA, as H.O. #9.
