Sail Performance : Techniques to Maximize Sail Power Hardcover – December 10, 2002

by C.A. Marchaj

This volume replaces Marchaj's classic Sailing Theory and Pactice, published 25 years ago, and offers new information on, rig design, sail construction and trim, wind-sail interaction, and the structure of the wind. The performance of any sailing craft depends largely on the power of the available sail--how the rig uses the wind and turns it into a useful driving force. But sail forces are determined by a multitude of factors, including wind speed, sail area and shape, and steadiness of the wind, among others. From wind-tunnel tests that he has conducted, Marchaj describes how these factors affect sail power and why certain rigs are superior in power and efficiency--concluding that the Bermuda, or marconi, rig is by no means the best available. This major work is an accessible, nonmathematical treatment of the subject and marks a turning point in modern thinking in the arena.

There was a lot of information in here but not much that was applicable or particularly interesting. Perhaps its just the writing style. At any rate, other technical sailing books have provided much more enlightenment per pound.

The definitive work on high performance sailing rigs. Marchaj's work is comprehensive and wide-ranging, including an in-depth windtunnel study of different rigs.
