Noted author, Leonard Gray treats us again with this potpourri of celestial navigation exercises, each designed around a specific journey; New York to Lisbon, Anchorage to Hilo, and Hungnam to Akita to name just a few. Each voyage (19 in all) presents not only realistic celestial observation data from which to work, but also presents other considerations germane to the type of voyage, which leaves the reader understanding the thought processes which separate the experienced navigator from the novice. The data is not all cookbook. All the solutions are not pretty, but are realistic, causing encounters which impart experience as well as practice; all the while having Mr. Gray standing just behind you with a tip or two when the going gets rough.
