What can sudden shifts in weight cause on board a vessel?

Sudden shifts in weight on board a vessel can introduce heeling moments, which significantly compromise stability. When weight is shifted rapidly from one side of the vessel to another, it creates an imbalance that can cause the vessel to heel, or tilt, more than intended. This heeling reduces the effective stabilizing forces of the vessel's design, such as the righting arm, which is crucial for maintaining an upright position.

As a vessel heels, the center of gravity shifts, which may lead to further instability. If the heeling moment exceeds the righting lever's ability to return the vessel to an upright position, risks such as capsizing can increase significantly. Understanding the implications of weight distribution is essential for maintaining a vessel's stability and ensuring the safety of both the crew and the vessel itself.
