The aim of the research is to compare the performance of catamaran and monohull technology for the hull form design of the livestock carrier as a vessel that transport the commodities such as cows, goats, and sheep. The investigation of resistance, intact stability and seakeeping performance of the both hull forms type will be discussed. Based on this study, it might be concluded that the catamaran design has better resistance performance in the high service speed than the monohull. On stability review, the initial stability of catamaran has enabled the larger transversal weight shifts than the monohull, which means the Catamaran has better safety level for livestock carrier. On motion review, the catamaran has better performances notably at roll motion. However, it is indicated that the operability should be limited to the significant wave height below 3 meters to avoid deck-wetness. Keywords: Catamaran, Livestock carrier, Monohull.
