What is the purpose of a vessel's stability tests?

The purpose of a vessel's stability tests is to ensure balance and control under various conditions. This involves evaluating how a vessel behaves in response to environmental factors such as wind, waves, and the distribution of weight on board. Stability tests help assess the vessel's center of gravity and center of buoyancy, which are crucial for maintaining upright posture and preventing capsizing. By conducting these tests, operators can determine whether a vessel has the necessary stability to operate safely in different scenarios, including rough seas and in the presence of shifting loads. The results from these tests inform decisions about loading practices, ballast use, and the overall safety of the vessel during operation.
