dynamic stability

Dynamic stability in nautical science refers to a ship's ability to resist capsizing, particularly in response to external forces like wind gusts or the lifting of heavy nets. Unlike static stability, which considers equilibrium, dynamic stability measures the energy required to rotate a vessel to a point where it loses stability. This is crucial for smaller vessels that are more susceptible to capsizing under normal operating conditions. The resisting energy is indicated by the area under the statical stability curve, and international standards, often set by the International Maritime Organization, are based on this principle to ensure ship safety.1
