The Ships from Field’s Point by C. Roger Wallin, Commander, US Navy Reserve, retired The Ships from Field’s Point commemorates an episode of local and regional history that occurred during World War II. At that time, an emergency shipyard was established at a waterfront neighborhood of Providence, Rhode Island. The yard at Field’s Point employed as many as 21,000 workers, and it built three types of ocean-going ships to support the war effort. Since the end of the war, there have been occasional articles in local newspapers that recalled the past existence of the shipyard, but there never has been an adequate description of the sixty-four ships that were produced there. Author C. Roger Wallin has focused his attention on those ships. This book describes the three types of ships and explains how they were armed and equipped to perform their assigned missions. It also addresses the wartime operational history of the ships, and continues with their use during the post war years. Finally, an appendix is included that indicates the significant milestone dates and the ultimate disposition of each of the 64 vessels.

Decreasing the magnetic field signature of a naval vessel will reduce its susceptibility to detonating naval influence mines and the probability of a submarine being detected by underwater barriers and maritime patrol aircraft. Both passive and active techniques for reducing the magnetic signatures produced by a vessel's ferromagnetism, roll-induced eddy currents, corrosion-related sources, and stray fields are presented. Mathematical models of simple hull shapes are used to predict the levels of signature reduction that might be achieved through the use of alternate construction materials. Also, the process of demagnetizing a steel-hulled ship is presented, along with the operation of shaft-grounding systems, paints, and alternate configurations for power distribution cables. In addition, active signature reduction technologies are described, such as degaussing and deamping, which attempt to cancel the fields surrounding a surface ship or submarine rather than eliminate its source.

Fundamentals of Ship Hydrodynamics: Fluid Mechanics, Ship Resistance and Propulsion Lothar Birk, University of New Orleans, USA Bridging the information gap between fluid mechanics and ship hydrodynamics Fundamentals of Ship Hydrodynamics is designed as a textbook for undergraduate education in ship resistance and propulsion. The book provides connections between basic training in calculus and fluid mechanics and the application of hydrodynamics in daily ship design practice. Based on a foundation in fluid mechanics, the origin, use, and limitations of experimental and computational procedures for resistance and propulsion estimates are explained. The book is subdivided into sixty chapters, providing background material for individual lectures. The unabridged treatment of equations and the extensive use of figures and examples enable students to study details at their own pace. Key features: • Covers the range from basic fluid mechanics to applied ship hydrodynamics. • Subdivided into 60 succinct chapters. • In-depth coverage of material enables self-study. • Around 250 figures and tables. Fundamentals of Ship Hydrodynamics is essential reading for students and staff of naval architecture, ocean engineering, and applied physics. The book is also useful for practicing naval architects and engineers who wish to brush up on the basics, prepare for a licensing exam, or expand their knowledge.

The Setaukets, Old Field, and Poquott is a rich collection of photographs, documents, and oral histories from the archives of the Three Village Historical Society and from generous residents. It reveals the bucolic old Setauket village center, with its farmers, craftsmen, and seamen who were the backbone of the community. This book portrays buildings that no longer exist and follows other structures, through the migration of the town center south and east, to their present location. It also shows aspects of village life in Old Field and Poquott, both established as residential communities in the early 20th century.
