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":"None","offers":[{"title":"Paperback","offer_id":46226333434066,"sku":"9780070059283","price":23.5,"currency_code":"CAD","in_stock":true},{"title":"Kobo eBook","offer_id":46226333466834,"sku":"deb64379-4da7-3fe2-89f3-b4b9943f73f0","price":18.49,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0655\/8980\/5233\/files\/1_f01a9a77-5902-4420-ac9a-44a85e2e0210.jpg?v=1763142968","url":"https:\/\/www.indigo.ca\/products\/celestial-navigation-for-yachtsmen","provider":"Indigo","version":"1.0","type":"link"}
