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 Thomas & Thomas Sextant Series Saltwater Fly Rods are constructed with a unique reinforcement strategy that increases strength and recovery properties of high-performance unidirectional fibers. This improves the coefficient of energy of the completed rod sections, resulting in rods that load quickly and generate wind-cutting line speed and casting distance with less effort. Although the Sextant series is designed to perform on the most demanding saltwater flats, the versatile rod actions are also a great choice casting with sinking or intermediate lines across a wide range of fishing conditions.

Bowditch explains how to select use and maintain The Marine Sextant with a special selection on identifying celestial bodys

Black and white drawings and photographs, appendixes.

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.

Artificial Horizon Answers the need of every sextant user who cannot depend on a natural sea horizon. Use for backyard practice, finding exact positon when inland, and making exact sextant shot on foggy mornings. To use, fill with water and read the angle of the reflected sun with your sextant. Half your sextant reading is the sun's angle above the true horizon. Windproof and corrosion resistant, the reflecting surface is completely enclosed. Comes with two sun shades, a lid and full directions. Compact 6" x 4" x 1-1/2" (15 x 10 x 4 cm).

Cape Horn Birthday documents the extraordinary non-stop round-the-world journey of a lone sailor and his thirty-two-foot sloop. GPS did not exist when Peter Freeman set sail from Victoria, British Columbia, in 1984. Peter navigated the old-fashioned way, with a compass, a sextant, books of tables, and his wits. Along the way, he had to rebuild the self-steering rudder, repair torn sails, and fix broken gear. Peter encountered a severe lightning storm, snow, and hailstorms as he sailed as close to the Antarctic ice as he dared. Near île Kerguélen in the South Indian Ocean, Laiviņa almost rolled over in a violent storm. While the little sloop was inverted, Peter was under water, helplessly tied to the pushpit rails holding his breath as he waited for the sturdy little craft to right herself. Along the New Zealand coastline, Peter joined in a race and took line honours for the Overseas Entry Class before crossing the Pacific back to Victoria, British Columbia. Upon arrival, Peter was greeted with the news that he had broken the existing world record.
