Fishing boats are an important means of supporting fishing activities, so they require strong, lightweight, and efficient materials or manufacturing methods. This activity aims to analyze the application of fiberglass matt and roving materials in the fishing boat manufacturing process and the effectiveness of manual boat mold manufacturing. The method used in this activity involved making manual molds from wood and Duraroc plywood, a lamination process using resin, fiberglass matt, and roving, as well as boat body construction and finishing. The results of the study show that the fiberglass molds produced are precise, stable, and can be used repeatedly, enabling the mass production of fishing boats with uniform quality. The combination of fiberglass matt and roving produces a strong, lightweight boat structure with even lamination thickness. Trials in the water show that the boats have good buoyancy, stability, and watertightness.
