"CMS" stands for "Center of Mass" in vessel stability, which refers to the point where the total mass of the vessel can be considered to be concentrated. Understanding the position of the center of mass is vital for assessing a vessel's stability, as it influences how the vessel reacts to forces like wind and waves. For a vessel to be stable, its center of mass must be located appropriately in relation to its buoyancy center. If the center of mass is too high or improperly positioned, it can lead to instability and increase the risk of capsizing.

In the context of vessel stability, knowing the center of mass helps in determining the right weight distribution and the placement of cargo, which ultimately affects the overall performance and safety of the vessel. Properly managing the center of mass is crucial for maintaining balance and heavy seas, as well as for ensuring safe operations while maneuvering or during adverse conditions.
