With a model of a combined passenger and cargo ship extensive resistance and propulsion tests were carried out in still water, as well as in regular and irregular longitudinal waves.

    The results of these experiments indicate that the mean increases of resistance, thrust, torque, r.p.m. and power, for constant speed and wavelength, vary with fair approximation as the square of the waveheight.

    The experiments confirm that the mean increase of power due to irregular head seas can be determined when the wave spectrum and the mean increase of power in the regular wave components is known.

    The increase of ship power in seawaves, as predicted from model test results is in good agreement with service performance data.
