A clean copy with a tight binding. N° de ref. de la librería
Fully updated, this authoritative and richly illustrated standard reference offers the latest information on rig design, sail construction and trim, wind-sail interaction, and the structure of the wind. From his 40 years of research and wind-tunnel tests, acknowledged expert Marchaj describes how these factors affect sail power and why certain rigs are superior in power and efficiency. Accessible and nonmathematical, this major work represents the cutting-edge wisdom on sailboat performance and makes a significant contribution to our understanding of this absorbing, complex subject.
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.
The performance of any sailing craft largely depends 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, sail shape, sail setting, the hull, angle of heel, wind gradient, and steadiness of the wind.
From wind tunnel tests which he has conducted, Tony Marchaj describes how these factors affect sail power and why certain rigs are superior in power and efficiency to others. The tests also indicate where improvements in efficiency may be made, particularly when freed from the constraints imposed by the arbitrary limitations of the racing rules.
Professor Marchaj compares a number of different types of rig--Bermudan, lateen, sprit, gunter, dipping lug and Polynesian crab claw--and concludes that the Bermudan rig, which dominates the contemporary sailing scene for racing and cruising, is by no means the best available.
This major work makes a significant contribution to our understanding of the factors which contribute to an efficient sailing rig, and is a landmark in modern thinking on the subject.
