Hydrodynamics of High-Speed Marine Vehicles, first published in 2006, discusses the three main categories of high-speed marine vehicles - vessels supported by submerged hulls, air cushions or foils. The wave environment, resistance, propulsion, seakeeping, sea loads and manoeuvring are extensively covered based on rational and simplified methods. Links to automatic control and structural mechanics are emphasized. A detailed description of waterjet propulsion is given and the effect of water depth on wash, resistance, sinkage and trim is discussed. Chapter topics include resistance and wash; slamming; air cushion-supported vessels, including a detailed discussion of wave-excited resonant oscillations in air cushion; and hydrofoil vessels. The book contains numerous illustrations, examples and exercises.

This is a comprehensive two-volume set of books devoted to the hydrodynamics of high-performance marine vessels. These vessels may also be generally referred to as high-speed or advanced marine craft. Types of craft addressed include monohulls, catamarans, trimarans and other multihull vessels, air-cushion vehicles, surface-effect ships and planing craft. The hydrodynamic aspects dealt with are the steady-state resistance, wave generation, sinkage and trim, unsteady effects and motions in waves. Separate chapters are devoted to viscous resistance, transom sterns and the behavior of skirts for air-cushion vehicles and seals for surface-effect ships. Effects of the finite depth of the water and the possible lateral restriction on the width of the waterway feature prominently in the books. In each case, the presentation includes a full analytical development of the theory accompanied by a comparison of the theoretical predictions with extensive experimental data. In the two volumes there is a total of 939 full-color Letter-size pages. The text is accompanied by 473 photographs of ships and ship models, 1202 graphs, 1294 equations and 1435 references. The work represents the author's research, consulting and professional experience in both universities and research centers spanning a period of over fifty years. The books are targeted at university-level students and specialized industry engineers in the field of naval architecture and associated areas.

This book details the efforts to build a large naval vessel capable of traveling at one hundred knots. It is the first book to summarize this extensive work from historical and technical perspectives. It explores the unique principles and challenges in the design of high-speed marine craft. This volume explores different hull form concepts, requiring an understanding of the four forces affecting the lift and the drag of the craft. The four forces covered are hydrostatic (buoyancy), hydro-dynamic, aerostatic, and aerodynamic. This text will appeal to naval researchers, architects, graduate students and historians, as well as others generally interested in naval architecture and propulsion.

High Performance Marine Vessels (HPMVs) range from the Fast Ferries to the latest high speed Navy Craft, including competition power boats and hydroplanes, hydrofoils, hovercraft, catamarans and other multi-hull craft. High Performance Marine Vessels covers the main concepts of HPMVs and discusses historical background, design features, services that have been successful and not so successful, and some sample data of the range of HPMVs to date. Included is a comparison of all HPMVs craft and the differences between them and descriptions of performance (hydrodynamics and aerodynamics). Readers will find a comprehensive overview of the design, development and building of HPMVs.

This book presents a theoretical treatment, as well as a summary of practical methods of computation, of the forces and moments that act on marine craft. Its aim is to provide the tools necessary for the prediction or simulation of craft motions in calm water and in waves. In addition to developing the required equations, the author gives relations that permit at least approximate evaluation of the coefficients so that useful results can be obtained. The approach begins with the equations of motion for rigid bodies, relative to fixed- and moving-coordinate systems; then, the hydrodynamic forces are examined, starting with hydrostatics and progressing to the forces on a moving vehicle in calm water and (after a review of water-wave theory) in waves. Several detailed examples are presented, including calculations of hydrostatics, horizontal- and vertical-plane directional stability, and wave-induced motions. Also included are unique discussions on various effects, such as fin-hull interactions, numerical stability of integrators, heavy torpedoes, and the dynamics of high-speed craft. The book is intended to be an introductory-level graduate text and a reference for the practicing professional.

Although the primary audience for this book is undergraduate university students studying naval architecture and marine engineering, the content will certainly be of interest to most designers working with high-speed craft. Author Donald L Blount says, "My intent has been to share the technical information, decision criteria, rules of thumb, and the opinionated experiences which have helped me in making choices for developing marine craft intended to operate beyond displacement speeds." According to Blount, Chapter One is a reprise of his article "Original Speed," (Professional BoatBuilder magazine, June/July 2008) followed by nine chapters of "science, my skewed views of science, a few things I don't understand, definitions of things on which no two naval architects will agree, design criteria which have been my friend, and guidance on design procedures embracing technology." This book also includes numerous graphs, charts, tables, and formulas to clarify the material in the text. He encourages you to personalize your copy with your own notes to make it even more valuable as a reference source and has included ample space for adding comments. ABOUT THE AUTHOR: Donald L Blount is the founder of Donald L. Blount and Associates, Inc. (Chesapeake, Virginia). During his 50-plus year career, he has designed numerous noteworthy vessels including the 67.7 m (222 ft) Destriero, which holds the non-refueled Atlantic crossing record, set in 1992 with an average speed of 53.1 knots earning the coveted Blue Ribband shown here. Registered as a professional engineer in two states, Blount is a fellow of both SNAME and RINA. He has served as Head of the Department of the U.S. Navy's Combatant Craft Engineering Department and also was employed at the David Taylor Model Basin. He has co-authored more than 50 papers and articles.

In the last half-century, high-speed water transportation has developed rapidly. Novel high-performance marine vehicles, such as the air cushion vehicle (ACV), surface effect ship (SES), high-speed monohull craft (MHC), catamaran (CAT), hydrofoil craft (HYC), wave-piercing craft (WPC) and small water area twin hull craft (SWATH) have all developed as concepts, achieving varying degrees of commercial and military success. Prototype ACV and SES have achieved speeds of 100 knots in at calm con- tions; however, the normal cruising speed for commercial operations has remained around 35–50 knots. This is partly due to increased drag in an average coastal s- way where such craft operate services and partly due to limitations of the propulsion systems for such craft. Water jets and water propellers face limitations due to c- itation at high speed, for example. SWATH are designed for reduced motions in a seaway, but the hull form is not a low drag form suitable for high-speed operation. So that seems to lead to a problem – maintain water contact and either water propulsion systems run out of power or craft motions and speed loss are a problem in higher seastates. The only way to higher speed would appear to be to disconnect completely from the water surface. You, the reader, might respond with a question about racing hydroplanes, which manage speeds of above 200 kph. Yes, true, but the power-to-weight ratio is extremely high on such racing machines and not economic if translated into a useful commercial vessel.
