Download or read book How to Use Plastic Sextants with Applications to Metal Sextants and a Review of Sextant Piloting written by David Burch and published by . This book was released on 2010-09 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.
