What is the purpose of the stability criteria established by the US Coast Guard?

The stability criteria established by the US Coast Guard are focused on maintaining safe operations of vessels under various loading and weather conditions. This involves evaluating how a vessel responds to different external forces, such as wind and waves, as well as internal factors like cargo or fuel load. By ensuring that a vessel meets specific stability requirements, the Coast Guard aims to prevent capsizing, ensure safe maneuvering, and protect the vessel's integrity.

Proper stability is crucial for vessels, especially when they are subjected to dynamic environmental conditions. For example, a vessel with inadequate stability might tilt excessively in rough seas, which could lead to loss of control or even capsizing. The criteria help operators understand the limits of their vessels and encourage adherence to best practices for loading and ballast management, promoting overall safety in maritime operations.
