Purse Seine Vessel Design under 100 GT Based on the Characteristics of South Sulawesi Waters in Indonesia

The waters of the Makassar Strait of South Sulawesi, where various Purse Seine vessels operate, have characteristics of very high biodiversity, the strength of very strong ocean currents, and the temperature and cultural characteristics of Bugisness and Makassar fishermen. It is necessary to design a purse seine ship that perfectly matches the designs of traditional ships operating in South Sulawesi waters so far. This research aims to create a purse seine vessel design under 100GT with International Maritime Organization standards that match the characteristics of the Makassar Strait. The Design Implementation Method is carried out by considering the length, width, height, shape of the ship's body, the volume of loading space, and construction weight by analyzing the main dimension ratio, hydrostatic parameter analysis and purse seine ship stability analysis. The design results were carried out using a length of 24 meters, width of 4.4 meters, and height of 1.9 meters. The shape of the purse seine vessel body is V-bottom shape, and the middle part towards the stern is U-V flat bottom. The tamping capacity of the first, Second and Third loading room size Volume is 29.48, 26.87 and 15.98 tons, respectively, and The Stowage factor fish is 0.5 tons/m. Ship stability or KG value to three conditions, namely the state of the ship heading to the fishing ground has a KG/VCG fluid value of 1.25 m, this value meets the IMO recommended standards, the second condition is the ship conducting fishing operations, the KG/VCG fluid value in the second condition is 1.22, and the third condition is the condition of the ship heading back to the fishing base, the KG/VCG value of 1.25 meters. The VCG/KG value of the three conditions has met the minimum value issued by IMO. The shape of the ship's body at the bow forms a "V-bottom" model, and at midship to stern has two forms of the ship's body, namely, a Round bottom and U-V flat bottom following the characteristics of South Sulawesi Waters.
