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