New winglets and a new rudder were designed by us for the International 8 Meter Class yacht “YQUEM” early in 2002.
The yacht participated in the World championships in Helsinki in July 2002 and the crew secured a 2nd place behind the new French boat “Fleur de Lys”. The Swiss owners were happy with this result and they then ordered a study of further possible improvements and a new keel.
We performed a large series of VPP calculations to determine the optimum value for various design parameters such as winglet chord and span, bulb dimensions, stability, trim tab dimensions, etc. The resulting keel was built in The Netherlands and was fitted to the boat in February 2003.
