This is a groundbreaking, technical analysis of yacht design, linked to the theory and testing of how a sailing yacht behaves underway. It is cutting edge - the author (a world expert in the field) has drawn his conclusions from years of research, analytical testing in wind tunnels and tanks, and his results represent the state of the art in performance prediction which underlies all modern yacht design. State of the art and with a revolutionary modern approach, Aero-hydrodynamics and the Performance of Sailing Yachts provides a systematic and completely up to date analysis, complete with colour photographs and diagrams throughout. An essential, and long awaited, work for all professional yacht designers, racing sailors and students of yacht design.
