A flexible and robust overlapping structured grid method is introduced and applied to the computation of the flow around two ship hulls with appendages. The ships are a frigate with sonar dome, bilge keels, propeller shafts, brackets, nozzles and rudder and a hopper-dredger with head-box, shafts, brackets and nozzle. Results are presented both for model and full scale and compared to experimental data.
