Preface

This book, like its predecessors, is based on Schneekluth's lectures at the Aachen University of Technology. The book is intended to support lectures on ship design, but also to serve as a reference book for ship designers throughout their careers. The book assumes basic knowledge of line drawing and conventional design, hydrostatics and hydrodynamics. The previous edition has been modernized, reorganizing the material on weight estimation and adding a chapter on power prognosis. Some outdated material or material of secondary relevance to ship design has been omitted.

The bibliography is still predominantly German for two reasons:

German literature is not well-known internationally and we would like to introduce some of the good work of our compatriots.

Due to their limited availability, many German works may provide information which is new to the international community.

Many colleagues have supported this work either by supplying data, references, and programs, or by proofreading and discussing. We are in this respect grateful to Walter Abicht, Werner Blendermann, Jurgen¨ Isensee, Frank Josten, Hans-Jorg¨ Petershagen, Heinrich Soding,¨ Mark Wobig (all TU Hamburg-Harburg), Norbert von der Stein (Schneekluth Hydrodynamik), Thorsten Grenz (Hapag-Lloyd, Hamburg), Uwe Hollenbach (Ship Design & Consult, Hamburg), and Gerhard Jensen (HSVA, Hamburg).

Despite all our efforts to avoid mistakes in formulas and statements, readers may still come across points that they would like to see corrected in the next edition, sometimes simply because of new developments in technology and changes to regulations. In such cases, we would appreciate readers contacting us with their suggestions.

This book is dedicated to Professor Dr.-Ing. Kurt Wendel in great admiration of his innumerable contributions to the field of ship design in Germany.
