In this report the authors have treated the theoretical considerations for the experimental results which were reported already. The values of M and D in course of the translatory oscillation of the hydrofoil are found on the basis of the studies by Theodorsen, Jone and Munk. These results are comparated with the measuring values and then it becomes clear that, (1) The virtual mass coefficient M for the translatory oscillation of the thin hydrofoil may be calculated by the same theory as the aerofoil. (2) The damping effect coefficient D is severely deviated from the theoretical valve for the aerofoil, except the vicinity of the attack angle 0°. As we concluded that the above deviation is caused by the unsteady cavitation due to the oscillation, the experimental formula of D has been given as the quadratic form of the attack angle.
