The theory and numerical methods used to determine the lift and drag of a yacht model from wind-tunnel wake measurements are discussed. The results from wake surveys taken downstream of a l/40th scale IACC model yacht are presented. The lift and drag distributions are given as well as plots of the total pressure loss, vorticity, and stream-function, which are helpful in understanding the flow structure.
