Expressions for unsteady lift and moment acting on oscillating hydrofoil are derived by extension of classical unsteady thin airfoil theory; method of images is employed to account for free surface, but additional contribution from surface waves is neglected; results of flutter computations, using station analysis, for ratios of depth of submergence to semichord of 2 and infinity; it is found that lower flutter speed corresponds to infinite depth of submergence.
