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.

The Nautical Sextant reveals in pictures, prose, and perspective the experience and knowledge gained by the author from years of acquiring, studying, and restoring sextants from earlier times and from around the world. This fascinating book owes much of its attraction to the expert description and photos of the mechanics of the sextants and their subassemblies. It is also the story of how different manufacturers, in different times and places, solved the same mechanical problems in different ways in order to perfect one of the most accurate mechanical devices ever produced by man. All of this is complemented by an historical overview to the current day, an overview which has never been published until now. The Nautical Sextant will be of particular value not only to navigators, but also to restorers, collectors, students of technology, curators, and sextant dealers. With its bibliography and extensive use of footnotes, this book will certainly become a classic in its field.

Many books on celestial navigation take shortcuts in explaining concepts; incorrect diagrams and discussion are often used for the sake of moving the student along quickly. This book tells the true story-and the whole story. It conveys celestial navigation concepts clearly and in the shortest possible time.It's tailored for navigation in the GPS age-a time of computers, calculators, and web resources. Although it covers all of the traditional methods of 'working a sight, ' the primary thrust is using the (under $10) scientific calculator. By using equations that you key into your calculator, this book guides you toward a better understanding of the concepts of celestial navigation.You will learn novel ways to plot lines of position, ways to check your sextant accurately by star sights, and how to tell what time it is from a moon sight. The many appendices are a treasure of references and explanations of abstract ideas. Celestial Navigation is a crucial skill for the offshore navigator to know, this book provides the shortest path to that knowledge.

Sextants are used to measure angular heights of celestial bodies above the horizon to find the latitude and longitude of the observer. They can also be used on land with artificial horizons. Sextants can also be used to find the correct Universal Time by measuring the angular distance between the moon and another body along its path across the zodiac. In coastal waters or on land, sextants can be used for very accurate piloting by measuring the horizontal angles between charted landmarks. The vertical angle of a peak above its baseline determines the distance to it, which, combined with a compass bearing, yields a position fix from just one landmark. The angular dip of an object (island or vessel) below the visible horizon can also be used to determine the distance to it. This booklet explains how to get the best results from plastic sextants, and presents numerical comparisons with similar data from metal sextants. Sextant piloting techniques are also reviewed as they are an ideal use of a plastic sextant.

In the spirit of early Bowditch editions, we offer navigation details of a full ocean passage as an excellent way to learn the ropes of practical celestial navigation. With your own tables and plotting sheets, you can analyze 224 timed sextant sights of sun, moon, stars, and planets to obtain 26 position fi xes to fi nd your way along a 2,800-nmi voyage lasting 17 days. Solutions are provided by computation, workforms, and detailed plots using universal plotting sheets. After completing this passage you will be prepared to navigate by celestial navigation on your own, whether you need to or choose to. Also includes notes on optimizing sight analysis, hurricane tracking, DR error analysis, ocean currents, and use of visible light ranges for nighttime arrivals.
