ROYAL NAVAL SUBMARINES

In the closing years of the nineteenth century only France could claim near-parity in the sea power with Great Britain. The "Entente Cordiale" was a decade away and France was regarded as a potential naval threat. This hazard increased by successful French attempts to build "sousmarins". Four such vessels were in use in the French navy by 1897, electrically powered and with compressed air reservoir; the largest was 160 ft long and displaced 266 tons...

THE COMPLETE YACHTMASTER

There are two groups of specialist sailing texts. One deals with matters such as navigation, boat handling and meteorology, with which every skipper must have more than a nodding acquaintance. The other caters for the ever-enlarging number of subjects relating less directly to the essence of moving a yacht safely from one location to another. The volume you are about to read is designed specifically for skippers and potential skippers. Its purpose is to gather together all those vital areas of expertise to be found in the first group of books, place them in a systematic order between two covers, and discuss them in a practical way. The book should therefore not only prove useful as a companion to a sailing course, either hands-on or theoretical, but will also provide a long-term work of reference for the boat's bookshelf. I make no claim that The Complete Yachtmaster is the only work you will require in order to take charge of a yacht on a round-the-world voyage. Certain items, such as the use of radio communications, require a specialist volume in their own right, and it is not insignificant that teaching the VHF syllabus is a separate subject in most mainstream training systems.

UNDERWATER WELDING OF OFFSHORE PLATFORMS AND PIPELINES

Anyone who has ever participated in the performance of a deep water hyperbaric weld will certainly agree that the successful welded connection, repair, and attachment of two pieces of steel in a dry environment is still one of the most ambitious and challenging projects with which the diving industry is confronted today. This book is aimed to provide the guidance on various aspects of underwater welding.

SHIP DESIGN FOR EFFICIENCY AND ECONOMY

Ship design for efficiency and economy
The main dimensions decide many of the ship's characteristics, e.g. stability, hold capacity, power requirements, and even economic efficiency. Therefore determining the main dimensions and ratios forms a particularly important phase in the overall design. The length, width, draught, depth, freeboard, and block coefficient should be determined first. The dimensions of a ship should be co-ordinated such that the ship satisfies the design conditions. However, the ship should not be larger than necessary. The characteristics desired by the shipping company can usually be achieved with various combinations of dimensions. This choice allows an economic optimum to be obtained whilst meeting company requirements...

SHIP DESIGN AND CONSTRUCTION

The aim of the book is essentially the same as that of the prior editions; namely, a textbook "to assist students and others entering the field of shipbuilding towards a knowledge of how merchant ships are designed and constructed and to provide them with a good background for further study." Nevertheless, a number of considerations led the Committee to modify extensively the scope and organization of the book. At the outset, the Committee recognized that within a few years the Society's book Principles of Naval Architecture would also be revised and that it contained material which more properly pertained to design and construction rather than theoretical naval architecture. Therefore it recommended, and the Publications Committee as well as the Executive Committee approved, the inclusion in Ship Design and Construction of new chapters on Load Lines, Tonnage, and Launching which would then be deleted from future editions of Principles of Naval Architecture. As a partial trade-off toward page reduction, the Committee eliminated the 1969 edition chapter on Submersibles because of its relatively narrow field of interest and the lack of major new developments for commercial operations.

U-BOATS VS DESTROYER ESCORTS: THE BATTLE OF THE ATLANTIC

The battle of the Atlantic pitted Germany's U-boats against Allied convoys sailing from North America and the South Atlantic. The name itself is a bit of a misnomer as it was not one single battle but the longest continuous military campaign of World War II, lasting for six years, stretching over hundreds of miles and involving almost countless combat engagements. By the end of hostilities, the Kriegsmarines U-boats had sunk in excess of 2,900 ships, representing over 12 million tons of Allied shipping. Despite some post-war claims that the U-boat campaign had no real chance of being successful in the long run, it is clear that the Allied leaders at the time had a different view. By January 1943. such were the worries over the U-boat's successes that at the Casablanca conference, it was agreed that the defeat of the U-boats was to be a number one priority. Indeed, when summarizing his thoughts on the Battle or the Atlantic, Prime Minister Winston Churchill famously said, 'The only thing that ever really frightened me during the war was the U-boat peril'. The Battle of the Atlantic was not only a fight for the survival of Great Britain, but for the survival of real opposition to Hitler. If the U-boat campaign had succeeded and Britain had been starved into subjugation, the British Isles wouldn't have served as a base for the eventual bombing offensive and as a launching point for the invasion of Kurope. It is difficult to envisage how the stakes could have been higher...
