On the Increase of the Resistance of a Ship in Rough Seas
Journal of Zosen Kiokai, 1957 The resistance of a ship among waves is discussed by means of the energy analysis. The result proves that the increase of wave-making resistance is the origin of the additional resistance due to the seaway. The resistance in irregular waves can be defined only by the statistical sense. It is expressed in terms of the resistance in regular waves.
