Wind tunnel testing to determine yacht performance has been carried out for at least the last 50 years. A common perception is that experimental methods do not improve significantly over time. This paper shows how modern wind tunnel testing is still the only realistic way of providing a complete picture of aerodynamic performance over a full range of conditions in a rapid and cost-effective manner. The use of a Real-Time VPP and a sail shape recognition system combine to enhance the accuracy and repeatability of testing. The influence of examining boat speed instead of driving force is investigated.
