Sail Performance : Techniques to Maximise Sail Power (Rev. ed)

Based on C.A. Marchaj's "Sailing Theory and Practice", this is a reference for sailors.

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 wind all affect sail power, and why certain rigs are superior in power and efficiency to others.

This revised edition explains developments and thinking since the last edition was published.
