The American Practical Navigator, first published in 1802, was billed as the "epitome of navigation" by its original author, Nathaniel Bowditch. The text has evolved with the advances in navigation practices since that first issue and continues to serve as a valuable reference for marine navigation in the modern day. The publication describes in detail the principles and factors of navigation, including piloting, electronic navigation, celestial navigation, mathematics, safety, oceanography and meterology. It also contains various tables used in typical navigational calculations and solutions, including the formulas used to derive the tabular data. - NGA

This 2019 edition of The American Practical Navigator (Bowditch), Pub No. 9, exists to codify the latest body of marine navigation knowledge and practical application. Its publication success is a result of the dedicated efforts of many hands and voices from academia, science and seafaring experts. This edition has advanced from the judiciously shaped recommendations-some comprehensive, some minute, all indispensable-of a multitude of maritime and science professionals. At the same time, it was equally essential that those recommendations be compared, vetted, and applied in a consistent manner and with a clear vision, a challenging task performed in exemplary fashion by this edition's principal editor, Dr. Gerard J. Clifford, Jr.

We now have two Sumner linee, A'and B', under Case I, whose common latitude is 25 19MS., and whose longitudes on the common parallel are 114 61K.7 and 115 31'.5. Hence, the difference of longitude on the common parallel is 115 31'.5 W. 114 59'.7 W. CHAPTER XVI. THE PEAOTIOE 01 NAVIGATION AT SEA. 381. Having set forth in previous chapters the methods of working dead reckoning and of solving problems to find the latitude, longitude, chronometer correction, and azimuth from astronomical observations, it will be the aim of the present chapter to describe the conditions which govern the choice and employment of the various problems, together with certain considerations by which the navigator may be guided in his practical work at sea. 382. Departure And Dead Reckoning.--On beginning a voyage, a good departure must, be taken while landmarks are still in view and favorably located for the purpose; this becomes the origin of the dead reckoning, which, with frequent new departures from positions by observation, is kept up to the completion of the voyage, thus enabling the mariner to know, with a fair degree of accuracy, the position of his vessel at any instant. At the moment of taking the departure, the reading of the patent log (which should have been put over at least long enough previously to be regularly running) must be recorded, and thereafter at the time of taking each sight and at every other time when a position is required for any purpose, the log reading must also be noted. It is likewise well to read the log each hour; for general information as to the speed of the vessel as well as to observe that it is in proper running order and that the rotator has not been fouled ...

In this engagingly written biography, Tamara Plakins Thornton delves into the life and work of Nathaniel Bowditch (1773-1838), a man Thomas Jefferson once called a "meteor in the hemisphere." Bowditch was a mathematician, astronomer, navigator, seafarer, and business executive whose Enlightenment-inspired perspectives shaped nineteenth-century capitalism while transforming American life more broadly. Enthralled with the precision and certainty of numbers and the unerring regularity of the physical universe, Bowditch operated and represented some of New England's most powerful institutions—from financial corporations to Harvard College—as clockwork mechanisms. By examining Bowditch's pathbreaking approaches to institutions, as well as the political and social controversies they provoked, Thornton's biography sheds new light on the rise of capitalism, American science, and social elites in the early republic. Fleshing out the multiple careers of Nathaniel Bowditch, this book is at once a lively biography, a window into the birth of bureaucracy, and a portrait of patrician life, giving us a broader, more-nuanced understanding of how powerful capitalists operated during this era and how the emerging quantitative sciences shaped the modern experience.

Perfect for fans of Scott Turow and John Lescroart, The Practical Navigator is a smart, fast-moving legal thriller where everyone's motives-and desires-are in question. Membership in the Great Arcadia, an exclusive East Coast yacht club, is pretty much limited to the rich and powerful in 1980s business, finance, and politics. But the sexually charged murder of Greek billionaire George Minot during their annual regatta off the coast of Maine opens a door into a secret world of addictive sexuality and excess beneath the starched sheets of the East Coast establishment. Tim Bigelow is looking forward to spending a week at sea with the magical Cassie Sears, who has suddenly appeared in his life. He's also there to celebrate his older brother, Harry-the retiring commodore of the Great Arcadia who's on course for a major role in the White House. That prospect slips away when Minot is murdered and details start to come out, including the alarming fact that Minot saw himself as a latter-day embodiment of the Minotaur-the half-man, half-bull creature who lurked in the Labyrinth beneath the ancient city of Knossos in one of the oldest myths in the Western canon. From the decks of the world's finest yachts to the beds and boardrooms of some of the most powerful people in America to an electrifying courtroom trial in a dying coastal town, The Practical Navigator steers a course through its own labyrinth . . . a whirlpool of obsessive sexuality, murder, and despair.

This book has been used for 30 years, updated periodically as needed. More than 20,000 students have successfully learned ocean navigation from these materials and gone on to cross oceans or circumnavigate the globe. This book covers how to find position at sea from timed sextant sights of the sun, moon, stars, and planets plus other routine and special procedures of safe, efficient offshore navigation. No previous navigation experience is required. The only math involved is arithmetic (adding and subtracting angles and times). This is a practical, how-to-do-it book, which also includes clear explanations of how it works and how to do it well. Plus this book includes other crucial factors of ocean navigation besides just finding out where you are from the stars, such as logbook procedures, dead reckoning, error analysis, route planning, and more. At the end of this book, you will be ready for ocean navigation. The book includes: text, practice problems, tables selections, detailed glossary, and full solutions. Printable work forms, plotting sheets, and other resources are available at no charge from www.starpath.com/celnavbook. Preface to the Second Edition: We are pleased to say that after ten more years of using this text we do not find reason to change the basic approach and methods of the teaching. We still use most of the same examples, which are now quite old, but that is the beauty of celestial navigation. It has not changed, so we do not benefit in any way from making all new examples, which would bring with them more chance of error in a book of many numbers. We have, however, notably improved and expanded the book. Each section has been updated and reformatted for a clearer presentation, often in response to student questions over the years. New graphics have been added and older ones all updated. There is much new content in the text, especially in the In-Depth chapter, including more detailed discussion of the sailings and more background on the principles. New sections were added on general ocean navigation and optimizing the fixes. We have also updated the electronic navigation section, as most ocean navigators will also be using other tools besides celestial.
