There are many ways that ship designers can do to get the minimum engine power with the desire ship speed. One of the ways is to design the bow shape with the aim of minimizing ship resistance. In this study, the ship resistance of hard-chine monohull with two different bow shapes that conventional and inverted bows are analyzed. CFD (Computational Fluid Dynamics) approach by using Shear Stress Transport (SST) as turbulence model is used. Different ship speed by Froude numbers Fr 0.2 to 0.7 is applied. The simulation results give convincing evidence that the inverted bow produces lower total resistance compared to the conventional one by about 5% reduction.
