A Review on the Fishing Boat Outrigger Design and Construction Development in Indonesia

Abstract

This study analyzes the designs, functions, and technological advancements of outrigger boats in Indonesia, emphasizing their critical role in enhancing the maritime stability and operational efficiency. Its objective is to examine how the innovations in the outrigger systems contribute to improving the vessel stability, safety, and sustainability, particularly in the fishing and transportation activities. The research methodology integrates observational data, dimensional measurements, material analysis, and an extensive literature review, focusing on the Indonesian fishing vessels. The key findings reveal that positioning the outrigger approximately 2 m from the vessel’s side significantly reduces ship motions, such as heaving, rolling, and yawing, thereby preventing the capsizing and enhancing safety. The innovations presented in this work include a portable and movable outrigger system that optimizes the stability and space utilization. Also, the hydrodynamic improvements reduce the drag, while the integration of a power generation system harnesses the water flow to supply electrical energy for onboard lighting, which is advantageous for night fishing. A shift from the simple changes in structure to more advanced designs is observed. The latter improve the way the water flows around the vessel, using energy from the water movement, which is part of a larger trend towards more sustainable and efficient operations at sea. These advancements enhance the vessel performance and contribute to the environmental protection by reducing the reliance on external energy sources. It is concluded that optimizing the outrigger designs is essential for promoting safer, more efficient, and environmentally sustainable fishing practices in Indonesia, offering valuable insights for future maritime engineering developments.
