Excerpt from Seagoing and Other: Concrete Ships The aim of the author has been to present a true record of the principal seagoing concrete ships actually built up to the present, and to analyse the merits of these ships in comparison with ships built of steel and wood. The main part of this book is based on personal experience gained in the construction of about thirty vessels of concrete during the past five years. The information referring to ships built by others has been obtained partly through correspondence with the designers, builders, or owners, and partly from statements published by them in the engineering press. As far as possible, facts have been ascertained from official documents, and reference to the source of information is made in each case The calculations are condensed in the Appendix and have, been avoided in the general text in order to facilitate the reading for shipping people and others, who will play an important part in the further development of the new type of ships without being concerned in the technical side of the question. The usual methods of calculating displacement, speed, etc., found in standard works on naval architecture, have been omitted, as they are practically identical for concrete ships. Numerous technical papers and articles on concrete ships have appeared in the press, but unfortunately the hopes or opinions expressed have frequently been based on anticipation rather than on actual experience. The result has been a mass of conflicting reports which have caused much confusion on the subject. If the present book should aid in clearly establishing the true status of the best type of seagoing concrete ship to-day, and thus form a basis for further development, the author's chief object will be accomplished.
