From a perspective of more than fifty years in the industry, the author wrote a wide-ranging work on all aspects of towing, in both inland and ocean waters. Part I, The Industry, gives an overview, followed by descriptions of types of tugs and modes of towing. Part II, Operations, covers getting the tug under way, under way with tow and at sea, and special types of towing. Towing as a Business, part III, deals with the shore establishment. More than fifty appendices consolidate data helpful to the tug-master. The text is illustrated with more than 300 drawings, photographs, diagrams, and other visual aids.
