It explains basic principles, table use and how to take sights with a sextant, without advanced mathematics &#8211; just simple addition and subtraction. The modern edition has been revised with example problems related to today&#8217;s nautical almanacs and tables, and serves as an indispensable reference book for long-distance sailors and navigators who want skills beyond electronic systems.   <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Classic and practical guide to astronomical navigation for sailors, focusing on sun, moon and star sighting without electronics.<\/p>\n","protected":false},"featured_media":39095,"comment_status":"open","ping_status":"closed","template":"","meta":{"_uag_custom_page_level_css":""},"product_brand":[1369],"product_cat":[1082],"product_tag":[],"class_list":["post-53451","product","type-product","status-publish","has-post-thumbnail","product_brand-adlard-coles","product_cat-navigation-and-seamanship","product_shipping_class-boxship","pa_produsent-adlard-coles","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"composite_virtual":false,"composite_layout":"","composite_add_to_cart_form_location":"","composite_editable_in_cart":false,"composite_sold_individually_context":"","composite_shop_price_calc":"","composite_components":[],"composite_scenarios":[],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.7 (Yoast SEO v27.7) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>Celestial Navigation for Yachtsmen - classic astronavigation for sailors | Kart.no<\/title>\n<meta name=\"description\" content=\"Learn astronomical navigation with this classic book.
