  • Rawson and Tupper's Basic Ship Theory, first published in 1968, is widely known as the standard introductory text for naval architecture students, as well as being a useful reference for the more experienced designer. The fifth edition continues to provide a balance between theory and practice. Volume 2 expands on the material in Volume 1, covering the dynamics behaviour of marine vehicles, hydrodynamics, manoeuvrability and seakeeping. It concludes with some case studies of particular ship types and a discussion of maritime design.

  • The recent fuel cell (FC) development worldwide has always been accompanied by a number of studies and projects investigating the applications of FCs onboard ships. Almost all possible FC types and different fuels such as hydrogen, natural gas (liquefied or pressurized), liquefied pressurized gas (LPG), methanol, and maritime diesel have been considered. These applications of FCs are still mainly focused on onboard power generation (OPU) and propulsion.

  • Submersibles are a large and nonhomogeneous group of vehicles that range from small unmanned autonomous vehicles such as Gavia and REMUS that can be carried by one or two men, to medium-large unmanned submersibles such as torpedoes, survey vehicles such as HUGIN and Bluefin, larger manned deep-diving vehicles such as the US Alvin and the Russian MIR up to naval diesel-electric submarines. With a few exceptions, all these use electrochemical power sources for propulsion.

  • Littoral warfare is the use of combined forces, designed for operations in the sea-land-air environment, to influence, deter, or contain and defeat a regional threat through the projection of maritime power. It is an extremely complex and dynamic part of naval warfare. To be waged successfully, it demands long-term commitment to research and development, acquisition, threat assessments, tactical and operational analysis, training, education, and realistic fleet exercises.

  • The three centuries that have gone by since this was written have afforded ample confirmation of the view here set forth, as to the importance of "Battailes by Sea" and the supreme value of the "Command of the Sea." Not only "we of Europe," but our kindred in America and our allies in Far Eastern Asia have now their proudly cherished memories of decisive naval victory. I propose to tell in non-technical and popular language the story of some of the most remarkable episodes in the history of sea power.
