Peter Nielsen is editor of SAIL magazine.

The art, science, history, and mystery of sails and sailmaking. Written in concise, layperson's language and full of photographs and personal anecdotes, this book goes step-by-step through the process of creating and using sails. Provided is a definitive look at the latest developments in sails, sailcloth, engineering, hardware, and sail trim. Also offered are case studies that illustrate which fibers, fabrics, and sails are suitable for a variety of different sailing applications, from simple dinghies and day sailors to offshore racing and cruising yachts. Sailors of all levels of interest and ability will find information they can apply to their own boats and sail choices.

Sail Performance, based on C A Marchaj's classic Sailing Theory & Practice, has established itself as the standard work on the subject and is now acclaimed as a milestone in sailing literature. From wind tunnel tests which he has conducted, Tony Marchaj describes how the factors of wind speed, sail area, sail shape, sail setting, the hull, angle of heel, wind gradient and steadiness of the wind all affect sail power, and why certain rigs are superior in power and efficiency to others. Sail Performance is a major work which is acclaimed for its analysis of the factors that contribute to an efficient sailing rig.

Windship Technology, Part A contains the proceedings of the International Symposium on Windship Technology (WINDTECH '85), held at the University of Southampton, England, on April 24-25, 1985. The symposium provided a forum for discussing developments in windship technology, including the use of calculation methods to analyze wind propulsion on cargo ships and weather routing for wind-assisted ships. Measurements of the comparative performance of sailing rigs are also presented. Comprised of 17 chapters, this volume begins by tracing the revival of serious interest in the possible use of the wind in ship propulsion over the past decade, and giving examples of the wide range of rigs that have been developed and are now installed on ships. The reader is then introduced to Project INDOSAIL intended to develop cargo sailing vessels for the Indonesian inter-island trade. Subsequent chapters focus on sail-assist developments from 1979 to 1984; economic aspects of the application of additional sail power on small German fishing vessels; sail retrofit on inter-island vessels in Fiji; and the aerodynamics of a triangular jib-and-boom combination. The book concludes with an evaluation of two-dimensional sail shape determined by pressure and its tension. This book will appeal to government officials, academics, ship owners, and other parties with an interest in windship technology.

The Congressional Record is the official record of the proceedings and debates of the United States Congress. It is published daily when Congress is in session. The Congressional Record began publication in 1873. Debates for sessions prior to 1873 are recorded in The Debates and Proceedings in the Congress of the United States (1789-1824), the Register of Debates in Congress (1824-1837), and the Congressional Globe (1833-1873)
