The fishery sectors in Indonesia have enormous potential including capture fishery potential of US$ 15.1
billion/year, marine aquaculture potential of US$ 46.7 billion/year, and aquaculture potential of US$ 10
billion/year. With abundant marine natural resources, the development program of Indonesia should notice the
increasing number and quality of fishing vessels. A good fishing vessel design has to consider the aspects of
efficiency, feasibility standards, and fishermen's safety. To achieve feasibility and safety standards, the design
process has to concern the characteristics of the waters where the fishing vessel operates. The Southern Java
waters are waters that have high waves with Hs ranging between 1.5 to 2 m. Therefore, a hydrodynamic
comparison of the hull between the V-shaped and U-shaped was carried out, including the evaluation of
resistance prediction, stability, and seakeeping to obtain the best vessel design criteria. The investigation was
carried out using the numerical method with the Computational Fluid Dynamics (CFD) approach. The results
showed that the V-shaped is better than the U-shaped because it produces lower resistance while the stability
and seakeeping performance are better.
