With worked examples that don't require anything more than simple addition and subtraction, this longstanding bestseller makes a tricky subject simple to understand.\u003cbr\u003e\u003cbr\u003eGroundbreaking in its approach when it was first published 65 years ago, it is equally relevant today. There have been huge advances in technology, but batteries can fail, aerials can go overboard and the risk of electronics getting wet means this traditional skill is as vital as ever.\u003cbr\u003e\u003cbr\u003eNow in its 13th edition, Mary Blewitt's classic guide has been thoroughly updated by former Reeds Almanac editor Andy Du Port to ensure that it remains entirely relevant to offshore sailors today. Andy has kept Mary's concise and clear style, which has helped make this the best known celestial navigation book ever published.","brand":"Adlard Coles Nautical","offers":[{"title":"Bargain","offer_id":42994347901008,"sku":"9781472942876B","price":9.99,"currency_code":"CAD","in_stock":false}],"url":"https:\/\/bookoutlet.com\/en-ca\/products\/celestial-navigation-for-yachtsmen-13th-edition","provider":"Book Outlet","version":"1.0","type":"link"}
