• Hydrodynamic interaction between hull and foils is one of the important aspects for performance prediction of high speed craft lifted up partially by sumberged foils. In order to investigate such interaction, measurements were made of the lift of foils, trim and elevation of a craft model in the towing tank. It was found that the elevation of the model is smaller than that estimated from the measured lift of the foils. This suggests that there exists lift loss due to additional sinkage force acting on the hull as a result of hydrodynamic interaction. Then, numerical calculation was carried out to clarify such hydrodynamic interaction. As expected, it was found that negative pressure is induced by the foil on the bottom of the hull just above the foil, and results in the sinkage force as observed in experiments.
