A series of carefully controlled experiments on the resistance of a model of a compartmented surface-effect ship has been conducted in a towing tank. Configurations of the model included cases encompassing one subcushion and two subcushions, as well as differing values of the pressures in the subcushions. It was shown that a reduced total resistance in the appropriate range of Froude number could be achieved in this manner. Furthermore, the previously developed theory for the resistance of a surface-effect ship was verified for the model for a Froude number greater than 0.40.
