Assessment of Fishing Vessel Vulnerability to Pure Loss of Stability Using a Self-Developed Program

“…The increase in displacement and the influence of the height of the center of gravity follow the law of change in calm water, but the change in the restoring arm caused by the change in displacement is more drastic, because by analyzing the Froude-Krylov hypopaper, the displacement change is more important in the restoring arm, whereas the displacement change in calm water only acts directly on the radius of the transverse center of gravity. Zhang et al [36] deduced that as the ratio of wave height to wavelength increases, the change in stability is due to the increase or decrease in the moment of inertia of the waterline surface at the front and rear of the hull. At the same time, the change in KG due to the change in height of the center of gravity ultimately affects the gradual decrease in the metacentric height.…”
