Seaworthiness of Pinisi Tourism Vessels Produced by Traditional Shipyards in Indonesia

The high demand for Pinisi tour boats as an icon of Indonesia’s maritime culture has led to an urgent need to ensure the safety and seaworthiness of these vessels. The transformation of Pinisi vessels from cargo ships to tourist vessels often neglects technical aspects such as stability and construction, thus increasing the risk of accidents, including sinking and fire incidents. The objective of this research is to assess the technical aspects of the seaworthiness and safety of Pinisi tour boats made in traditional shipyards in Bulukumba, South Sulawesi. The stability of the ship, its building system, and the impact of changes on its seaworthiness are all evaluated in the analysis. The findings demonstrated the superior seaworthiness of Pinisi ships built by conventional shipyards, according to the International Maritime Organization’s (IMO) guidelines. However, because the ship was altered for tourism purposes, the angle of vanishing stability decreased by 22.73% and the Metacentric Indication (MG) value decreased by approximately 5.25%. To improve shipping safety, it is recommended that the construction be strengthened, materials used under the requirements of the timber shipping regulations be used, and navigation technology be carefully loaded and integrated without losing its Pinisi characteristics. This research contributes to improving maritime safety, sustainable tourism development, and preservation of cultural heritage in Indonesia’s traditional shipping industry.
