The field of marine hydrodynamics has broadened greatly over the past 40 years, with applications to a wide variety of vessels and structures. These include systems for converting energy from the wind, waves, and currents; yachts, high-speed vessels, aquaculture facilities, and various types of submerged vessels; and traditional applications to ships and offshore platforms. The support for education and research has grown accordingly; it is gratifying that the term "marine hydrodynamics" has become ubiquitous for university departments, research laboratories, conferences, and publications.
The basic topics of the field are unchanged, corresponding broadly to the chapters of this text. Numerical methods that extend the applications of the theory have been developed. Practicing engineers and naval architects are now making routine use of well-established programs to optimize their designs and predict performance. These programs include Navier-Stokes solvers, which analyze viscous effects including turbulence, and "panel" programs based on boundary-integral equations to solve potential flow problems including lifting and wave effects. This evolution has been accelerated by the universal access to computers of increasing capacity and convenience. Nevertheless, it is essential to understand the underlying principles covered in this text, and to compare the results of computations with simpler approximations to be confident of their validity. I am grateful to the MIT Press for suggesting this special edition and for making it available economically, both as a paperback and as an open access e-book. I am especially grateful to Professor John Grue for the foreword, which reflects his long experience using this text.
