The numerical computation method to explore the wave-making resistance for a case of the small ship with skeg in calm water's surface condition is described. The problem is solved using the theory of Thin ship since it suitable for a case of slenderness of ship's hull. The distribution of source along the hull's centre plane is written in the Green function which is a form of Havelock source in ideal flow beneath free surfaces. In numerical computation, the approach of Tent function is proposed to discretize the form of the ship's hull developed from the data offset for solving the Michell integral problem. Employing the numerical methods developed, the wave resistance prediction for the case of the Wigley hull and the traditional fishing ship 'Madura' in Indonesia are conducted within several of Froude numbers. Numerical results show an effect of the hull's skeg on the ship's resistance due to wave after body significantly.
