This paper presents the numerical investigation of ship resistance of Indonesian traditional fishing vessel. The Open-source computational fluid dynamics (CFD) library, OpenFOAM, was used to predict three dimensional, incompressible, unsteady RANS equations for the ship resistance. The volume of fluid (VOF) method is used to predict the resistance. InterFoam solver is adopted to solve the computational problem. The KCS model was calculated and compared to the experimental result for validating the solver and relatively good agreement is achieved, then can be used to simulate the present model. The present model was using Indonesian traditional fishing vessel from the north and south coastal of Java island. The water condition in this study is in calm water condition and the same Froude number (Fn) for both models. As a result, the presented model for preliminary total resistance prediction in advance of the evaluation of the traditional fishing vessel performances.
