What are the stability criteria established by the USCG?

The stability criteria established by the USCG are essential for ensuring that vessels remain upright and safe during various conditions at sea. These criteria define minimum stability regulations that vessels must meet to ensure they can withstand forces such as wind and waves without capsizing. The standards are based on various factors, including the center of gravity, metacentric height, and the righting arm, which collectively contribute to a vessel’s ability to return to an upright position after being tilted.

In contrast, maximum speed limits, recommendations for loading and unloading procedures, and criteria for engine performance, while important for safe vessel operation, do not specifically address the stability of the vessel itself. Stability regulations focus exclusively on how well a vessel can maintain its balance in different conditions, thus prioritizing the safety of the crew, cargo, and the integrity of the vessel.
