Manfred Curry

An understanding of air and water flow

Ppl

In 1925, Curry (1899-1953), an American scientist living in Munich, published a book titled _The Aerodynamics of Sails and Racing Tactics _, a book that took sail trim and design from the theoretical to the real by measuring how wind flowed over sails and accurately describing the patterns. A breakthrough discovery made by Curry was that "the suction effect in the lee of the sail amounts to three to four times the positive pressure on its windward surface."

Curry was also a champion in dinghies, his results reflecting his understanding of air and water flow over sails and centerboards as well as his command of tactics and strategy.

To this day his book provides any sailor with an easy to understand explanation of why sails work as well as the tools to come out on top using tactics and strategy.
