This paper discusses the use of foil-shaped center bulb in catamaran fishing vessels, where the length, width, and height of the center bulb were configured into six variations. This study aims to get the best configuration that can most reduce the total resistance of catamaran fishing vessels. Ship resistance was tested at Fr 0.15 to Fr 0.35 using the CFD method. The results showed that the best model was found in Model 6, where the length of the center bulb was 15% greater while the width and height were smaller by 10% from the original one. Model 6 can reduce resistance by 10.68%.
