The successful 1976 challenge was an excellent test of the modern wing sail concept of the Australian boat vs. the equally modern and sophisticated "soft" sail rig of the U.S. challenger. The very complete data taken on site by the designer of Miss Nylex during the races has been compared with computer predictions of the comparative performance of the two boats based on aerodynamic and weight differences. The predicted outcome is in good agreement with the observed result. The analysis illustrates the points of comparative superiority and weakness of the two configurations quite clearly, prompting a prediction of the future course of developments for both rigs.
