Abstract

The designed hull form of the ship may influence the stability of the ship floating in the water. The existing equipment may affect the operational performance of the ship in which the height of the draft of the ship controls the floating ability and comfortable stability. The purpose of this research was to obtain the stability data from the traditional fishing boat models with various standard sizes according to the ratio of width/draft (D /B). An optimal design output was computed to meet the various criteria required for the design using computational software. The resulting comparison of trim (TF or TA) showed that the movement of the point of gravity is relatively small. This indicates that the influence of ship movement and external forces either from sea waves or wind has a high enough on changes in the center of gravity. Therefore the effect of using the (D/B) value ratio greatly determines the comfort and stability of the ship when operating to the fishing ground.
