{"product_id":"celestial-navigation-for-yachtsmen-9780070059283","title":"Celestial Navigation for Yachtsmen","description":"\u003cp\u003eThere is deep mystery and profound satisfaction in finding your position on earth by reference to the sun, moon, and stars--not to mention profound relief when the GPS receiver stops working in mid-passage. That is why knowledge of celestial navigation is still a rite of initiation, and its practice still a favorite pastime among serious cruisers.\u003c\/p\u003e\u003cp\u003eThat this edition of \u003ci\u003eCelestial Navigation for Yachtsmen\u003c\/i\u003e should appear 44 years after the first British edition and 27 years after its first publication in the U.S. is eloquent testimony to the author's clear, concise explanation of a difficult skill. Through those years, \u003ci\u003eCelestial Navigation for Yachtsmen\u003c\/i\u003e has been the best-known, best-loved primer on the subject throughout the English-speaking world. It successfully teaches sailors who have been demoralized by bigger books. It remains \"the famous little book\" on celestial navigation.\u003c\/p\u003e\u003cp\u003eAmong other changes, this edition substitutes the Nautical Almanac for the Air Almanac, discusses the \"short\" tables based on H.O. 211, expands the discussion in a few areas, fine-tunes it in others, and shows how to advance a line of position for a running fix from sun sights. The only mathematics involved are straightforward addition and subtraction.\u003c\/p\u003e\u003cp\u003e\u003ci\u003eCelestial Navigation for Yachtsmen\u003c\/i\u003e has spawned many imitators over the years, but it's still the best--with this new edition more than ever.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAbout the Author\u003c\/b\u003e\u003cbr\u003e\u003cb\u003eMary Blewitt\u003c\/b\u003e was involved with sailing for most of her life.
