    Cugle's Practical Navigation
    From: Dave Walden
    Date: 2006 Mar 29, 15:14 -0800

    Cugle's Practical Navigation, Charles H. Cugle, E.P.
    Dutton&Co., Inc., NY, 1938.
    
    I found mine on the web for $3 plus shipping!
    
    I've found it helpful and interesting.
    
    Seems to have been reasonably popular.  First printing
    1924, second 1926, third 1926, fourth 1927, fifth
    1929, sixth new and enlarged edition 1930, seventh
    1932, new revised edition 1936, new revised edition
    1938. I've seen of other later editions.  Dutton, a
    major publisher in the US.
    
    Extract from the Preface to the New and Revised
    Edition:
    
    
    "...All of the various problems are worked out in
    full, with no attempt to save figures or cut down the
    working in any way.  It is recommended to the beginner
    that he name everything as he goes along in his
    problems, since it will help to memorize.
    ...The author feels that all of the necessary problems
    in navigation have been taken care of in this volume,
    and that it is the most easily understood one ever
    published.
            There are many excellent books on the theory of
    navigation, but very few that the ordinary man can
    understand, and this book has been published with
    theory eliminated entirely."
    
    The first third of the book deals with Rules of the
    Road, Ship Stability, some Naval Architecture,
    piloting and costal navigation.  Starting with Chapter
    9, (his IX), he gets into topics more relevant to this
    list.  In a typical chapter, he first gives the method
    in a page or two of "Rules", he then gives about a
    dozen fully worked examples.
