A numerical method is developed for calculating boundary-layer and wake flows around a strut-keel/bulb system of the International America's Cup Class (IACC) sailing yacht. The Reynolds-averaged Navier-Stoked and continuity equations are solved with the Baldwin-Lomax turbulence model, using a body conforming grid, finite-analytic discretization, and a PISO-type velocity-pressure coupling algorithm. In addition, circulating water channel experiments are performed for hydrodynamic force measurements and flow visualization on the body surface. An overview is given for the present numerical approach, and numerical results are presented and discussed for two-types of test strut-keel and bulb models, including detailed comparison with the experimental data.
