Malay fishing boat improvement: hull design and stability analysis / Raziq Syahmi Mohd. Rohailan

The purse seiner Malay fishing boat is a vessel that plays a vital role in the coastal fishing communities of Southeast Asia. The project's primary objective is to create a suitable hull design for new Malay fishing boats, and concurrently, to analyze the hull stability. The problem with the current purse seiner boat is because of outdated material and the Deck house placement problem. The scope of work for this project will cover 3D hull design work, lines plan creation, hydrostatic data, and general arrangement. Then, for the stability work it will cover for both lightship and full load conditions in work area of initial stability, GZ curve (large angle stability) and Trim Analysis. This project contribute to the long-term sustainability and success of the fishing industry while ensuring the boats can withstand the challenges of the marine environment. The methodology is by creating the new hull design and analyze the hull hydrostatic data. For stability assessment finding the total weight, Longitudinal Center of Gravity (LCG), and Vertical Center of Gravity (VCG) by doing the weight estimation works. Initial stability analysis will help in finding the Metacentric height (GM) value. Then, GZ Curve graph to find the maximum angle of heel for both lightship and full load conditions.
