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.
There has been tremendous growth in the development of advanced marine vehicles over the last few decades and many of these developments have been presented at the International High Performance Marine Vehicles Conference held annually since 1997 in Shanghai, China. This comprehensive first volume covers high speed monohulls, multihulls, hydrofoil craft, air cavity craft and wing-in-ground effect craft. The papers cover a wide variety of hullforms, including deep-V hulls, stepped hulls, axe-bow hullforms, trimarans and pentamarans, foil assisted catamarans and air-lubrication craft. All aspects of design, including resistance, powering, seakeeping and maneuvering performance of these vessels, are covered through theoretical, experimental and numerical investigations.
The amphibious versatility, marine speed and low footprint pressure have given the hovercraft a role in specialized applications. Among them are search and rescue, emergency medical services, military and arctic operations, icebreaking, patrol, law enforcement, ferries, and recreational activities such as racing. To meet these demands, the hovercraft has undergone considerable development since its inception. A comprehensive and timely review of the analysis, design, operation, economics and applications of hovercraft is presented in this volume by a team of highly qualified experts. The topics covered range from first principles to the state-of-the-art, with extensive references to current literature. The overall presentation is intended not to exceed the final year level of undergraduate engineering. The introduction and summary sections of all chapters are intended to give a qualitative grasp of the material covered without having to read all the technical portions. In varying degrees, the volume will appeal to managers, decision-support staff, operators, technologists, undergraduate students, and anyone entering the hovercraft field or seeking an introduction to it. It will also be of interest to design engineers, researchers and graduate students. Thus, this volume can serve as an up-to-date reference on several important aspects of hovercraft for a wide range of readers.
Tourism has become a major international industry, with many countries all over the world relying on the income it produces. Its economic advantages as a major source of finance and employment leads to its active promotion by governments and other institutions, independent of the consequences on the environment, ecology and social structure of affected regions.Conference topics include the following; Tourism strategies; Tourism as a tool of development; Emergent strategies for tourism development; Environmental issues; Climate change and effects of natural hazards in tourism; Tourism and protected areas; Art, architecture and culture; Rural tourism; Modelling; Community involvement; Tourism and the built environment; Renovation of mature destinations; heritage tourism; medical tourism.Sustainable Tourism 2012 will adopt a multi-disciplinary approach and will aim specifically to foster greater understanding and collaboration between scientists and social science experts, practitioners and policy makers. It will take a broad view of this sophisticated and complex industry, and will examine the practice of sustainable tourism from global travel trends through to destination and site management. Innovative solutions, including those involving ecological tourism are particularly welcome, as well as cultural initiatives that will lead to better approaches to tourism with the objective of preserving the diversity of our planet.
This definitive text describes the theory and design both of Air Cushion Vehicles (ACV) and Surface Effect Ships (SES). It begins by introducing hovercraft types and their development and application throughout the world in the last three decades, before going on to discuss the theoretical aspects of ACV and SES craft covering their hovering performance, dynamic trim over calm water, resistance, stability, manoeuvrability, skirt configuration and analysis of forces acting on the skirts, ACV and SES seakeeping, and the methodology of scaling aerodynamic and hydrodynamic forces acting on the ACV/SES from model test data. The latter chapters describe a design methodology, including design criteria and standard methods for estimating craft performance, lift system design, skirt design, hull structure, propulsion systems and power unit selection. Much technical information, data, and references to further work on hovercraft and SES design is provided. The book will be a useful reference to engineers, technicians, teachers, students (both undergraduate and postgraduate), operators etc. who are involved in ACV/SES research, design, construction and operation. Guides the reader on how to perform machinery and systems selection within ACV and SES overall design For teachers, students (both at under- and post-graduate level), engineers and technicians involved in ACV/SES
'Jane's High-Speed Marine Transportation 2011-2012' provides comprehensive and detailed specifications, complete with images, on all types of high-speed marine craft including component and propulsion systems.
This is the 11th in the series of directories whose overall aim is to make sense of the myriad files in the marketplace by listing databases completely, and grouping them logically. The title, Company Information, implies a somewhat narrower focus than the directory offers, as the five sections ac
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.
