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.
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.
