A survey of the wake of a keel/bulb/wing configuration is presented and analysed in detail. It is shown that - Wake measurements can be useful for validation of flow field predictions using RANS - RANS simulations can in turn be used to explain the measured wake fow patterns - Wake measurements can be used to highlight important differences between design alternatives. In the current test case the wake measurements helped to point out the effect of winglets. This effect could also be related to pressure differences on the bulb computed with RANS
