On the surface, choosing the correct propeller for a particular boat seems simple. But one factor affects another, which then affects another factor, leading many boaters to believe that propeller selection depends more on black magic than logic. All the questions are answered in this complete reference, the first of its kind. This clear, easy-to-use handbook for all small boats is written not for Ph. D. s seeking the latest wrinkle in high-tech propeller design, but as a practical aid for the average mechanic, engineer, boatbuilder, fleet operator, serious yachtsman, or naval architect. | The Propeller Handbook: The Complete Reference for Choosing Installing and Understanding Boat Propellers by Dave Gerr, Paperback | Indigo Chapters
