Astro-navigation from Square One to Ocean-master begins at the very beginning of this relatively complex subject and progresses logically through all the required "astro skills". Each new concept builds on UNDERSTANDING with no "learning by rote". A 130-word glossary, 160 diagrams and 40 worked examples, all using 2011 Sun, Moon, planet and star data, are contained in 308 pages.
