{"product_id":"celestial-navigation-for-yachtsmen-book-mary-blewitt-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.\u003c\/p\u003e","brand":"WoB","offers":[{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":49596820586769,"sku":"GOR005034075","price":21.3,"currency_code":"GBP","in_stock":true},{"title":"GB \/ WELL_READ \/ INTERNAL","offer_id":49656423350545,"sku":"GOR013473791","price":5.4,"currency_code":"GBP","in_stock":false},{"title":"US \/ GOOD \/ SBYB","offer_id":50097818272017,"sku":"CIN0070059284G","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ VERY_GOOD \/ SBYB","offer_id":50300005581073,"sku":"CIN0070059284VG","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ WELL_READ \/ SBYB","offer_id":50461313171729,"sku":"CIN0070059284A","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ NEW \/ INGRAM","offer_id":50999303995665,"sku":"NIN9780070059283","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"GB \/ GOOD \/ INTERNAL","offer_id":51392322830609,"sku":"GOR010099319","price":6.2,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0070059284.jpg?v=1751004911","url":"https:\/\/www.worldofbooks.com\/en-gb\/products\/celestial-navigation-for-yachtsmen-book-mary-blewitt-9780070059283","provider":"World of Books ","version":"1.0","type":"link"}
