Book Description
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.

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1920 Excerpt: ...is the same as the latitude of the point on the line A', R/J 25 19'.4 S. B115 31.5 W. 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 ...

Book Description
I am honored to welcome you to the 2017 edition of The American Practical Navigator, or as most mariners refer to it, "Bowditch." 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.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. CAPT Brian D. Connon, United States Navy Director.PART 1, FUNDAMENTALS, includes an overview of the topic of marine navigation and the organizations which develop, support and regulate it. These fundamentals include chapters relating to geodesy and chart datums; modern hydrography; the types, structure, use and limitations of nautical charts; electronic chart display and information systems.PART 2, PILOTING, mainly emphasizes the practical aspects of navigating a vessel in restricted waters, using both traditional and electronic methods.PART 3, CELESTIAL NAVIGATION, reflects the renewed interest in the age old art and science of navigation by the stars, planets, moon and sun. PART 4, INERTIAL NAVIGATION, is often referred to as a sophisticated dead reckoning method. The topic is re-introduced in the 2017 edition.PART 5, RF NAVIGATION TECHNIQUES, explains the nature of radio waves and electronic navigation systems. Chapters deal with several electronic methods of navigation--satellite, Loran, and Radar, with special emphasis on satellite navigation systems.PART 6, ALTERNATIVE NAVIGATION TECHNIQUES, addresses the topic of bathymetric navigation. Doppler sonar navigation is also reintroduced.PART 7, NAVIGATIONAL SAFETY, discusses recent developments in management of navigational resources, the changing role of the navigator, distress and safety communications, procedures for emergency navigation, and the increasingly complex web of navigation regulations.PART 8, ICE & POLAR NAVIGATION, a chapter on polar navigation is reintroduced in the 2017 edition.PART 9, OCEANOGRAPHY, has been updated to reflect the latest science and terminology.PART 10, MARINE METEOROLOGY, incorporates updated weather information and many new graphics.

Nathaniel Bowditch and the Power of Numbers
Author: Tamara Plakins ThorntonPublisher: UNC Press Books
ISBN: 1469626942
Category : Biography & Autobiography
Languages : en
Pages : 417
Book Description
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.
