==History== |
|||
The most popular navigational text of the late 18th century was ''The Practical Navigator'' by [[John Hamilton Moore]] of the [[Royal Navy]], first published in 1772. To have exact tables to work from, Bowditch recomputed all of Moore's tables, and rearranged and expanded the work. He contacted the US publisher of the work, [[Edmund March Blunt]], who asked him to correct and revise the third edition on his fifth voyage. The task was so extensive that Bowditch decided to write his own book, and to "put down in the book nothing I can't teach the crew." On that trip, it is said that every man of the crew of 12, including the ship's cook, became competent to take and calculate lunar observations and to plot the correct position of the ship. ''The New Practical Navigator'' was published in 1799, followed by a second edition in 1800. |
|||
By 1802, when Blunt was ready to publish a third edition, Nathaniel Bowditch and others had corrected so many errors in Moore's work that Blunt decided to publish it as the first edition of a new work, ''The New American Practical Navigator''. The current edition of the ''American Practical Navigator'' traces its pedigree to that 1802 edition. Edmund M. Blunt continued to publish the book until 1833; upon his retirement, his sons, Edmund and George, assumed publication. The elder Blunt died in 1862; his son Edmund followed in 1866. The next year, 1867, George Blunt sold the copyright to the government for $25,000. The government has published ''Bowditch'' ever since. George Blunt died in 1878. |
|||
Nathaniel Bowditch continued to correct and revise the book until his death in 1838. Upon his death, the editorial responsibility for ''The New American Practical Navigator'' passed to his son, [[Ingersoll Bowditch|J. Ingersoll Bowditch]]. Very few significant changes were made under him. Editions from 1837 through 1880 are nearly identical in content. Ingersoll Bowditch continued editing the ''Navigator'' until George Blunt sold the copyright to the government. He outlived all of the principals involved in publishing and editing the ''Navigator'', dying in 1889. |
|||
The U.S. government has published some 52 editions since acquiring the copyright to the book that has come to be known simply by its original author's name, "Bowditch". Since the government began production, the book has been known by its year of publishing, instead of by the edition number. After the first major revision, a total overhaul of the book's content completed in 1880 under the direction of Commander [[Philip H. Cooper]], USN, the name was changed to ''American Practical Navigator''. Much of Bowditch's original content, including his methods for clearing [[Lunar distance (navigation)|lunar distance]] observations, were dropped in 1880 (though a new method for clearing lunars remained in an appendix until the early 20th century). After numerous incremental revisions and printings in the period from 1914 to 1944, ''Bowditch'' was extensively revised between 1946 and 1958. |

|||
The present volume, while retaining the basic format of the 1958 version, reorganizes the subjects, deletes obsolete text, and adds new material to keep pace with the extensive changes in navigation that have taken place in the electronic age. |
|||
The 1995 edition of the ''American Practical Navigator'' incorporates extensive changes in organization, content, and format. Recent advances in navigational electronics, communications, positioning, and other technologies have transformed the way navigation is practiced at sea, and it is clear that even more changes are forthcoming. The changes to this edition of ''Bowditch'' are intended to ensure that this publication remains the premier reference work for practical marine navigation. Concerted efforts were made to return to Nathaniel Bowditch's original intention "to put down in the book nothing I can't teach the crew." To this end, many complex formulas and equations have been eliminated, and emphasis placed on the capabilities and limitations of various navigation systems and how to use them, instead of explaining complex technical and theoretical details. This edition replaces but does not cancel former editions, which may be retained and consulted as to navigation methods not discussed therein. |
|||
The current edition (as of June 2017) is Edition 53, a two-volume, all-digital version released by NGA in 2017. |
|||
The Bicentennial Edition (2002) incorporated Volume 1 and Volume 2 into a single printed volume, with the goal of putting as much useful information before the navigator as possible in the most understandable and readable format, a single, hard-bound volume. While that edition saw widespread use in civilian, military and commercial fleets, it sacrificed some data on classical celestial navigation and on advances in satellite and electronic navigation to meet the compressed requirements of the physical form. Twenty years later, with a resurgence of interest in celestial navigation and the large-scale adoption of electronic navigation, NGA returned Pub. No. 9 to a two-volume format to encompass the expanded material. The NGA's latest printed edition is available in both two separate volumes but also offering a version where it incorporates both volumes into one book. The latest edition was issued in 2019 with freely downloadable PDFs available in the NGA's official website updated to June 2021. |

The American Practical Navigator (colloquially often referred to as Bowditch), originally written by Nathaniel Bowditch, is an encyclopedia of navigation. It serves as a valuable handbook on oceanography and meteorology, and contains useful tables and a maritime glossary. In 1867 the copyright and plates were bought by the Hydrographic Office of the United States Navy. As of 2019 it is still published by the U.S. Government and is available free online from the National Geospatial-Intelligence Agency (NGA), the modern successor agency to the 19th Century Hydrographic Office. The publication is considered one of America's nautical institutions.[citation needed]
