Printed on acid-free paper Springer is part of Springer Science+Business Media (www.springer.com) Preface Speed is not simply about velocity in air or water but should be considered in context with its purpose and the tools available. Until recently in historical terms, the motive power available for travel over the water was manpower itself or wind. Over many centuries sailing vessels have been refi ned so that they could harness more of its power effi ciently, and reach higher into an oncoming wind so as to perform a more direct route to the objective. The wind is not available to order nevertheless, and so “speed” achieved is not constant. The invention of reciprocating engines, initially steam driven, made a step change for maritime transport, just as it did on land a little over two centuries ago. It changed the meaning of speed over water, since not only could a vessel be designed to travel directly to its destination, but also could transport much greater payloads than pos- sible previously, and could deliver independent of the weather environment. In the fi rst century of powered marine craft, speeds increased from around 20 knots to about double that. At such speed, there are challenges even for large craft due to rapid increase of drag on the hull if a boat continues to try to push its way through. The propeller driving such a vessel also loses effi ciency due to a phe- nomenon known as cavitation unless specially designed to harness it. In the early part of the twentieth century, pioneering engineers conquered both problems and developed planing craft that could travel much faster by skimming over the water surface. The racing fraternity that grew in this period took things to the limit and produced craft that were in danger of fl ying if a stray gust of wind should hit. Commercial and military craft have not tested these boundaries quite so close, even though in the last half century service speeds for passenger ferry trans- port have doubled. The search for more speed—humanity has a tendency always to seek more—has been enabled through increasingly effi cient and lightweight power plants such as high-speed diesels and gas turbine engines, and lighter and stronger structural mate- rials (aluminium alloy, GRP, titanium alloy), that have enabled designers of fast boats, hydrofoils, and air-cushion craft to develop performance close to physical limits of speed in a seaway. v vi Preface In the last 30 years or so, a revolution in electronics has given us the possibility for automated stabilization of motions that was simply not possible before, together with big strides in power plant effi ciency, not to mention satellite navigation. These have been important enablers to comfort at higher speed and high-speed vessel development. A series of new variations of high-speed craft or high-performance marine vessels (HPMV) have been developed in the last half century, including improved planing monohull craft from the 1940s, hydrofoils from the 1950s air-cushion vehi- cles and surface effect ships from the 1960s, small water plane area twin hull craft from the 1970s, high-speed catamarans from the 1980s, wave piercing craft from the 1990s, high-speed trimarans in the fi rst decade of twenty-fi rst century, and wing in ground effect craft from 1970s to the present. These various concepts and the hybrids that we will describe form an interacting group of vehicle concepts. Designers, scientists, and various organizations both commercial, military and governmental have dedicated resources over the last century, and particularly heav- ily in the last 50 years to fi nd ways that combinations of the hull geometries, hydro- foils, and static or dynamic air cushions can be used to deliver speedy vessels that can perform very challenging missions. This work continues, still strongly driven by military objectives, and increasingly now by energy effi ciency and environmen- tal impact rather than simply the mission envelope defi ned by speed/payload/ environment/range. A product such as a high-speed marine vessel can only be successful if it is able to fulfi l a market requirement in an appropriate way. To deliver people or cargo effi ciently, there must be a timing fi t, often with other transportation linking in at each end of the mission. This applies in the military environment just as much as for Ferries or utility missions. As the other transport elements develop, this also changes the demand for the marine transport and can affect their continued success in ser- vice. Until recently it has been the cost of fuel that has played a large part in HPMV economy. While this continues, the cost inclusive of environmental impact is becom- ing a strong driver to further develop powering effi ciency. Both technology and human society are continually developing. To the present largely fuelled by hydrocarbon-derived energy, this societal development has accel- erated greatly over the past half century as the population has also grown worldwide mainly concentrated around large cities. Fast marine craft have matured, while still having a much wider variety of concepts in use than that available for passenger aircraft that have converged to a narrow variation around a geometrical confi gura- tion and mass production. Maybe this is because the range of applications is much wider for HPMV. It does at least continue to offer opportunities for Aero-Marine Engineers to be involved in a wide range of concepts and challenging operations! In this book, we refer to the craft family as HPMV, as the vessels are not only built for high speed, but may also have other attributes such as amphibious capability (air-cushion vehicles) or extreme seaworthiness (SWATH). Specialists from some countries refer to such craft simply as high-speed craft (HSC); however, the use of HPMV is more common now, and we will use that description and acro- nym in this book. Preface vii The authors have been concerned with HPMV for a long time. Liang Yun has more than 40 years of experience at the Marine Design and Research Institute of China, Shanghai (MARIC), and 20 years plus as the Chairman of HPMV Design subcommittee of the China Society of Naval Architecture and Marine engineering, CSNAME, as well as organizing the annual International HPMV Conference, Shanghai, China for a dozen years. He has been involved in ACV development in China since the very fi rst prototypes were constructed in Harbin in the late 1950s and has been involved to some extent in design of many other vessel types treated here. Alan Bliault has also worked in the ACV industry in its early days as a Naval Architect, but became involved in the offshore oil industry in the early 1980s and so has led a double life since that time, in order to maintain his connections with the world of fast marine craft. Some while ago, we decided to write a series of books on the analysis and design of different HPMV and have completed two on individual craft: “Theory and Design of Air Cushion Craft” (2000); “WIG and Ekranoplan, Ground Effect Technology” (2009) presenting the hydrodynamic and aerodynamic theory behind these two types. This will be followed by volumes on Catamarans/Trimarans and Monohulls/ Hydrofoils in due course. We do feel that many people have a strong interest in this technology, however while many HPMV are in operation in different parts of the world, until now there has not been a single volume giving an overview, discussing the differences and special features between them, as well as the approach to selection taken in various cases for both civil and military applications. So, we present this book entitled “High-Performance Marine Vessels” for reader’s interest. We cover as many HPMV concepts as practical within a single volume, with technical summary descriptions and discussion of the design drivers as an introduc- tion for a wide readership. We include many pictures and fi gures describing the shapes and confi gurations as well as features of various HPMV, together with some tables to introduce the leading particulars of the craft types. Our idea with this book has been to survey HPMV development, the market drivers, and the responses over time of the marine construction industry. The book introduces the HPMV family of craft concepts in Chap. 1 . Chapters 2 – 6 introduce successively the ACV, SES, WIG, Hydrofoils, Monohulls, Catamarans, Wave piercers, and Trimarans. In Chap. 7 hybrid and novel HPMV confi gurations are surveyed.
