ANALYSIS OF RESISTANCE AND STABILITY IN THE MODIFICATION OF OUTRIGGED FISHING BOAT DESIGN IN THE PUGER WATER, JEMBER

Fishing boats are one of the essential means of transportation for fishers. In Puger, fishing boats are crafted by traditional boat builders who have passed down their skills through generations. However, the effectiveness of the bow stem design of these fishing boats remains unknown. This research aims to analyze the impact of the bow stem shape on the resistance and stability values of the boat. This research utilized an outrigger fishing boat design with the following dimensions: a length overall (LOA) of 11 m, a beam (B) of 1.5 m, a height (H) of 1.5 m, and a draft (T) of 0.5 m. We compared the boat's original design and its modified bow design. The results of this study indicate that the modified design has a 16.327% lower resistance. Regarding stability, the modified design shows a 12.7% greater GZ (upholding arm value) and a 2.1% smaller heel compared to the initial design. Additionally, the modified design has a rolling period that is 5.8% faster than the original design. The modified design has better resistance and stability than the initial design.
