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.
