Optimization of the Internal Structure and Shape of a 470 Dinghy Centerboard
Paper in proceedings, 2020

The purpose of this paper is to design an improved centerboard for the Olympic 470
sailing dinghy sailing upwind. The design is improved by introducing a composite design that
makes the centerboard twist to windward when sailing upwind, thereby reducing the angle of
attack of the hull. The results show that a beneficial twist up to 1.5° is possible to achieve without
compromising the centerboard strength. According to our estimates, by utilizing the improved
design it is possible to obtain a gain of up to 9 s per race in a world cup race.
