It is well-known that horizontal and torsional vibrations of a ship cause a coupled vibration because in general the center of gravity of a ship dose not coincide with the center of twist of a ship. We think that the papers published by K. Ohtaka and others explained this problem fairly well. Attempting to make more clearer the fundamental qualities of this problem, we analysed the problem regarding the horizontal vibration as the shear vibration, and the results obtained were compared with those obtained by the paper above mentioned. As a result of this work, the phenomenon of the torsion-horizontal vibration is represented by comparativly simple formulae and some interesting conclusions are obtained. We think that the results obtained in this paper are good guidance in analysing the torsion-horizontal vibration of a ship.
