Sail Performance : Techniques to Maximise Sail Power
By C.A. Marchaj
Sail Performance is based on C A Marchaj's classic Sailing Theory & Practice.
From wind tunnel tests which he has conducted, 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.
