Based upon on Marchaj's "Sailing Theory and Practice" , this volume explains the many developments in sail performance that have taken place. The author explains the factors that affect sail power and why certain rigs have superior power and efficiency.

About the Author

Tony Marchaj's expertise in wind tunnel and test tank research, combined with his practical sailing experience, make him uniquely qualified to write this book. Previously a research fellow in the Department of Aeronautics and Astronautics at Southampton University, he is now an independent aerodynamics consultant whose experience and advice is sought all around the world.

Each of his previous books--Sailing Theory and Practice, Aero-hydrodynamics of Sailing and Seaworthiness: the Forgotten Factor--have become classic references, and his technical paper on "Design for Extreme Conditions" was awarded the coveted Silver Medal by the Royal Institute of Naval Architects, of which he is a member.

Tony Marchaj's love of sailing began in his native Poland, where he was national Finn champion. It has continued with involvement in many different research projects, ranging from 12-metre rig design to third world fishing fleets. He now lives at his rural retreat in France.
