This pre-history of the sextant, as we might call it, will emphasize the problems that were to be overcome in leading up to the invention, or rather evolution, of an instrument that has for long been the very symbol of the navigator's art.

Loran and GPS notwithstanding, there will always be a place for the sextant aboard any blue-water boat, if for no other reason than the thrill and mystery of finding one's position on earth by gazing at the heavens. Here is the indispensable reference that should accompany the instrument aboard. Cmdr. Bruce Bauer, a professional navigator and master mariner with the U.S. Merchant Marine, has distilled years of hands-on experience into an eminently readable guide to buying, adjusting, using, and repairing sextants. The Sextant Handbook is dedicated to the premise that electronic navigation devices, while too convenient to disregard, are too vulnerable to rely on exclusively. The book is designed to make beginner and expert alike conversant with this most beautiful and functional of the navigator's tools. Topics include: Assembly and Disassembly Vital Adjustments Avoiding Problems Rough Weather Sightings Oiling and Cleaning Immersion Baths Emergency Silvering Finding and Buying Used Sextants And Much More You'll also find a list of distributors, manufacturers, and dealers worldwide, a discussion of future trends, and numerous helpful hints, including sighting with eyeglasses and using a Rude starfinder. All in a thoroughly revised edition of a book acclaimed by navigation professionals.

In the tradition of Dava Sobel's Longitude comes sailing expert David Barrie's compelling and dramatic tale of invention and discovery—an eloquent elegy to one of the most important navigational instruments ever created, and the daring mariners who used it to explore, conquer, and map the world. Since its invention in 1759, a mariner's most prized possession has been the sextant. A navigation tool that measures the angle between a celestial object and the horizon, the sextant allowed sailors to pinpoint their exact location at sea. David Barrie chronicles the sextant's development and shows how it not only saved the lives of navigators in wild and dangerous seas, but played a pivotal role in their ability to map the globe. He synthesizes centuries of seafaring history and the daring sailors who have become legend, including James Cook, Matthew Flinders, Robert Fitz-Roy, Frank Worsley of the Endurance, and Joshua Slocum, the redoubtable old "lunarian" and first single-handed-round-the-world yachtsman. He also recounts his own maiden voyage, and insights gleaned from his experiences as a practiced seaman and navigator. Full of heroism, danger, and excitement, told with an infectious sense of wonder, Sextant offers a new look at a masterful achievement that changed the course of history.

Sextants at Greenwich consists of two main sections: The introductory chapters and the catalogue of navigating instruments of the National Maritime Museum. The first section gives a general overview of the history of celestial navigation with an emphasis on the instruments that were developed and used for that purpose, between about 1450 and the 1970s. The instruments in the catalogue form the main thread in these chapters. The catalogue consists of 347 entries of instruments for celestial navigation, the octants, sextants and related instruments preserved in the National Maritime Museum. Each entry includes the place of the object's origin, its maker, the object's date, inscriptions (by the maker and/or relating to an owner), the graduated scale, the instrument's dimensions and a general description that includes details such as used materials and detached parts. Finally the object's provenance (previous owners and/or users) and references to literature on its history and handling are given.

Not illustrated. 1914 edition. Excerpt: ...be seen and an observation taken, using the star telescope of the sextant; if the moon is shining, its light will be a material aid; but results obtained from such sights should be regarded as questionable and used with caution. Altitudes measured, however, just before sunrise and just after sunset are open to no such criticism; a fairly well-practiced observer who takes a series of sights at such a time, setting the sextant for equal intervals of altitude, will find the regularity of the corresponding time intervals such as to assure him of accuracy. 392. Identification Of Unknown Bodies.--On account of the very great value to be derived from the use of stars and planets in navigation, it is strongly recommended that all navigators familiarize themselves with the names and positions of those fixed stars whose magnitude renders possible their employment for observations, and also with the general characteristics--magnitude and color--of the three planets (Venus, Jupiter, and Mars) which are most frequently used. A study of the different portions of the heavens, with the aid of any of the numerous charts and books which bear upon the subject, will enable the navigator to recognize the more important constellations and single stars by their situation with relation to each other and to the pole and the equator. It may occur, however, that occasion will arise for observing a body whose name is not known, either because it has not been learned, or because the surrounding stars by which it is usually identified are obscured by clouds or rendered invisible by moonlight or daylight. In such a case the observer may estimate the hour angle and declination (the hour angle applied to local sidereal time giving the right ascension), and the star or...
