 note = {The activities of fishermen in archipelago regions (Eastern Indonesia and Pacific) mostly relate to the efforts in catching fishes and other marine resources. One of the most valuable fish is Tuna which is caught by simple up to modern big vessels and fishing gears. Most Moluccas fishermen are using small “tuna longboats” for this purpose. Those small boats operate in open seas where most of the time the sea conditions are rough. In many cases, those small boats could not resist in such conditions which will end-up with flooding, capsizing or sinking. Some records showed the fishermen and boats are lost at sea. A study was executed to solve this problem. Three new tuna long boats, with the size of 1.5 GT each, were designed. Those boats were provided with solid boxes inside to provide reserve buoyancy. The boats were constructed with the material of composite (Fibre Glass Reinforced Plastic). Then, the boats were tested at sea. The results of test showed that for a maximum flooding of boats, they still float (unsinkable) with a minimum trim level. In addition, for a capsize condition, they were still afloat and easily were returned to upright position. The results of boat design and evaluating were recommended to be applied to the users. A training program was conducted for the local boat builders during the study. Nowadays, the local boat builders have developed this unsinkable concept to their new boats into the market.},
