This study examines the impact of bilge keels on the performance of a tourist boat prototype within the context of the National Unmanned Fast Boat Contest. Computational methods were used to simulate and analyze the resistance, stability, and wake flow patterns of the boat with variations in the shape, width, and position of the bilge keels. The method used in this research is Computational Fluid Dynamics (CFD). The results show that the addition of bilge keels can significantly affect the boat's resistance and stability. Simulations were conducted using Ansys Fluent and Maxsurf Stability. Bilge keels greatly influence the reduction of the rolling motion of the boat caused by sea waves. By reducing this rolling motion, bilge keels help to decrease the additional resistance forces acting on the boat. The trapezoidal bilge keel positioned at 0.5r with a width of 2 cm has the lowest resistance value, which is 5.297 N. This is because placing the bilge keel at the 0.5r position helps to better dampen the rolling motion of the boat. Better reduction of the rolling motion helps to improve the overall stability of the boat. The bilge keel at the 0.75r position provides better stability for each model, especially with a width of 4 cm. This has the potential to reduce the total resistance as the boat can move more stably in the water. The triangular bilge keel shows the best results in reducing the wake resistance of the boat when placed at the 0.5r position from the boat's centerline. Simulations show that the width of the triangular bilge keel, particularly 4 cm, provides optimal results by producing a smaller and more tapered wake flow pattern.
