Description

The sextant, little changed since it appeared 250 years ago, was the first mass-produced instrument of real precision. In the rough hands of a navigator, from the unstable footing of a small vessel, it has long been the tool to pinpoint his position. Bill Morris, in his masterly dissection of the many varieties of sextants, relishes precision and clarity, in his words and his many detailed illustrations. Those leave the reader with an itch to dismantle and overhaul his own sextant, with complete confidence to reassemble and readjust it afterwards, guided by the wise words of a man with vast experience of the many makes and types that exist.
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.
