High speed catamaran and multihull high speed marine vessel have become very popular in the last two decades. The catamaran has become the vessel of choice for the majority of high speed ferry operators worldwide. There have been significant advances in structural materials, and structural design has been combined with higher power density and fuel efficient engines to deliver ferries of increasing size. The multihull has proven itself to be a suitable configuration for active power projection across oceans as well as for coastal patrol and protection, operating at high speedd for insertion or retrieval with a low energy capability. At present there is no easily accessible material covering the combination of hydrodynamics, aerodynamics, and design issues including structures, powering and propulsion for these vehicles. Coverage in High Speed Catamarans and Multihulls includes an introduction to the history, evolution, and development of catamarans, followed by a theoretical calculation of wave resistance in shallow and deep water, as well as the drag components of the multihull. A discussion of vessel concept design describing design characteristics, empirical regression for determination of principal dimensions in preliminary design, general arrangement, and methods is also included. The book concludes with a discussion of experimental future vehicles currently in development including the small waterplane twin hull vessels, wave piercing catamarans, planing catamarans, tunnel planing catamarans and other multihull vessels.

The modern cruising catamaran has arrived The arguments are over and the verdict is in--cruising catamarans comprise a rapidly growing percentage of the cruising fleet worldwide. Their advantages of space, stability, speed, and handling under power are truly compelling, and modern cats are every bit as reliable as monohulls. This long overdue, in-depth guide will help you choose and cruise the right catamaran for your needs. “An authoritative guide for novices and experienced sailors; the best book written on the subjects since the early 1990s.”--“Trimaran” Jim Brown, renowned multihull designer “In Catamarans, Gregor Tarjan shares his enthusiasm for yachts with two hulls, based on years of sailing all types. An excellent introduction.”--Dick Newick, legendary catamaran and trimaran designer “If you are contemplating spending hundreds of thousands of dollars on a cruising catamaran, the small price of this book is probably the best investment you could possibly start with.”--from the Foreword by Charles K. Chiodi, publisher of Multihulls Magazine

Principles of Yacht Design has established itself as the standard book on the subject for practising designers, naval architecture students, discerning boat owners as well as the boatbuilding industry as a whole. The fifth edition is completely revised and expanded. It examines every aspect of the process of yacht and powerboat design. The new edition includes new findings from recent research in aero and hydrodynamics, as well as covering the most recent changes to building standards. The authors have used a newly built 41-foot performance cruiser to demonstrate the practical application of yacht design theory. This new edition includes photos of the building process and detailed explanations.

"The monograph presents the main results of the author's sixty-year activity in science and engineering fields regarding the application of various multi-hull ships. The shown data are based mainly on the wide experimental results of the author. For fullness of description, some problems are explained in brief by the experimental results of other authors whose names are shown in the text and references. The scope of topics includes a brief history of applications, a list of types, hydrostatics and stability, towing resistance and propulsion in calm water and high seas, seaworthiness, maneuverability, external loads, structural arrangements and strength, general arrangement, and proposed concept designs. The scope of architectural types encompasses the variety of multi-hull 'species' from catamarans to trimarans as well as the other triple-hull ships, and ships with a small water-plane area (SWA ships). The type and size of ship range from small fast crafts to large ferries, from passenger ships to transatlantic container-carriers, and from high-speed patrol boats to naval combat and auxiliary ships. This is a development of a kind of technical encyclopedia previously published as three books: Multi-hull Ships by V. Dubrovsky and A. Lyakhovitsky (2001), Ships with Outriggers, by V. Dubrovsky (2004), Ships with Small Water-Plane Area, by V. Dubrovsky, K. Matveev, S. Sutulo, with detailed explanations of the newest data. In this respect, the book is unique and the most universal one written in English today. A brief history of applications is given as the base for future developments. The introduction contains a list of ship types and full terminology. Chapter One describes the specificity of general arrangement. Chapter Two speaks of how stability and non-sinkability differ clearly from the same qualities of mono-hulls. Chapter Three delves into resistance in calm water (major specificity and its use, series test results of catamarans with low-lengthening hulls, and twin- and triple-hull SWA models). Chapter Four is about seakeeping and performance on high seas (specifics of motion and the universal method of comparative evaluation). Chapter Five teaches readers about controllability and maneuverability specificity. Chapter Six shows structural strength (external loads, hull girder stress analysis and design, and simplified methods). Chapter Seven deals with d esign (basic factors, specific design algorithms and limitations, some new concepts: super-fast wave-piercing trimaran; 'semi-gliding' ships with small water-plane area, S/P SWA ships, feeder and fast container-carriers, motor yachts, carriers of helicopters and unmanned aircraft; transatlantic container-carriers, cruise ships, passenger ships for unequipped coasts, ships for seismic researching, multi-purpose pleasure and inexpensive research vessels, some small-sized vessels, and combat ships from corvettes to aircraft-carriers). The book is addressed to all kinds of readers involved in the production and operation of ships, including owners, designers, naval architects, marine engineers, professors and students, as well as planning and ship-operating managers"--From publisher's website.

The aim and scope of this book primarily deals with conceptual design of sea-going marine vessels. While there are a few books on similar topics available to the reader, this book takes a different approach to address the developments of many different types of vessels. Of significant interest would be the estimation of principal parameters of such as vessels and the various coefficients required for design purposes. These parameters are obviously not readily available without carrying out an extensive search and background study. Hopefully, this textbook may be of relevance to designers and career naval architects who need a reference to initiate the design process.
