Naval architecture

Since the publication of the first edition of this book, the subjects resistance and power of ships and screw propulsion have been placed on a much more satisfactory basis by the experimental work of Naval Constructor Taylor and R.E. Froude, Esq., so that the corresponding chapters can be presented more simply and with much greater certainty. The tables of properties of propellers are based on Mr. Taylor's experiments, but the concordance between his work and that of Mr. Froude virtually bases them on the experiments of both. The design and construction of propellers are based on projected area ratio, which is believed to increase the certainty and convenience of such work. Opportunity is taken to make some changes in other parts of the book.
