The direct formulation of boundary element method (BEM) based on the thick wing theory, which is expected to be a more accurate method than lifting surface theory, to the analysis of three-dimensional flow around the marine propeller in uniform flow has been presented at the 1st report for the need of more accurate prediction of pressure distribution acting on the surface of the propeller blade. In the present paper, BEM formulation is extended to the marine propeller in steady ship's wake. The present method is applied to the analysis of flowfields around conventional propeller and highly skewed propeller. The result is compared with that of the lifting surface theory (LST), and the usefulness of the present method for the problem of marine propeller in steady ship's wake is verified.
