ResumoA new computational method is presented for the design of optimal keels for racing yachts. The method was used in the design of the 1987 America's Cup winner Stars & Stripes. Lift and induced drag are computed with an extended version of the VSAERO panel method program, employing a far-field wake integration technique. Parametric studies of lift and induced drag performance for variations of keel and winglet geometry are presented. The optimal configuration for the expected racing conditions was chosen through a sailing performance code which accepted as input the parameterized lift and induced drag relationships.
