Abstract: Calculated and measured ship motions in longitudinal regular and irregular waves are compared and discussed. As examples of the superposition principle the probability of shipping green water and the occurence of slamming in irregular waves is determined. The influence of these phenomena on the sustained sea speed of a ship is discussed. The increased resistance and power of a ship in a given wave spectrum are analysed and the prediction for the ship in an irregular wave, agrees satisfactorily with full scale observations.
