This study aims to determine the effect of adding variations of fin stabilizers on the hydrodynamic characteristics of the ship design. It compares the hull without modification with the hull modified by a fin stabilizer on a prototype scale. The results of this study is assessed to obtain the best performance of ships with various models to be used in the design of ship realization. The research method is conducted by numerical approach, including simulation of resistance, stability, and seakeeping. The hull design references chosen are the Fast Police Boat and SMIT Patrol Boat with a Length Overall value of 1 m. The fin stabilizer uses hydrofoil type NACA-0015 with an aspect ratio of 0.7. Then the length variations are 3 cm, 4 cm, and 5 cm, with angle variations being 25°, 30°, and 35°. The results showed that adding a fin stabilizer could increase the ship's stability. The best fin stabilizers variations are fins with a length of 5 cm and an angle of 30° for the prototype design of the Fast Police Boat hull and fins with a length of 5 cm and an angle of 35° for the prototype design of the SMIT Patrol Boat hull.
