2017 American Practical Navigator Bowditch Volume 1 2

The 2017 edition of the American Practical Navigator returns to a two-volume format. This package includes both volumes, 1 and 2 bound separately. 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 meteorology. It also contains various tables used in typical navigational calculations and solutions, including the formulas used to derive the tabular data. Many of these solutions can also be found using the on-line calculators located in the Nautical Calculators section of this Web site.

This is the completely NEW EDITION of The American Practical Navigator Vol 2. "I am honored to welcome you to the 2017 edition of Publication No. 9, The American Practical Navigator, or as most mariners refer to it, "Bowditch." As a young Surface Warfare Officer serving in my first ship, I quickly learned Bowditch should be my first resource for all things related to navigation, oceanography and meteorology. I never imagined that 25 years later, I would be privileged to lead the team entrusted with updating this incredible document. One can hardly imagine the time, effort, and pressure involved in undertaking such a task--this is Bowditch, after all. None of us alone can equal the talent, experience and skill of Nathaniel Bowditch, as expressed in his first edition of 1802. As a result, this edition is the outcome of countless hours of hard work by many dedicated, passionate, and skilled colleagues from a variety of disciplines. And it was this team of scientific and operational navigation experts, led by Dr. Jerry Clifford, which has created this contemporary edition that stands ready to address the challenges faced by today's navigators and mariners. Please take the time to read the long list of contributors to this edition, I know you will be impressed by the depth and quality of our team. Since the last edition, there have been huge advancements in positioning methodologies and navigation systems. In some cases, what was old is new again, so we focused considerable effort into improving the celestial navigation and piloting chapters. Hand-plotting latent fixes on paper charts has been overtaken by Electronic Chart Display and Information Systems that continuously tell you where you are, provide warnings when standing into danger, and display radar and Automatic Identification System information to heighten situational awareness. Older graphics have been replaced by newer, higher resolution images to better illustrate the purpose of the text. Needless to say, we are justifiably proud of this 2017 edition and equally honored to continue such a noteworthy legacy of the navigational expertise first introduced by Nathaniel Bowditch 215 years ago. Wherever you may sail, I trust this fine resource will assure your safe passage. I wish you all fair winds and following seas. CAPT Brian D.

A fictionalized biography of the mathematician and astronomer who realized his childhood desire to become a ship's captain and authored The American Practical Navigator.

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.

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.
