How does a reduction of the center of gravity influence stability?

A reduction of the center of gravity enhances stability by generally increasing the metacentric height. When the center of gravity of a vessel is lowered, it allows the center of buoyancy to shift upward when the vessel leans to one side. This shift increases the distance between the center of gravity and the metacenter, which is the point about which the vessel pivots when tilted. A greater distance between these two points results in a larger metacentric height, improving the vessel's stabilities.

In practical terms, greater metacentric height means that the vessel will return to an upright position more quickly after being inclined by external forces, such as wind or waves. Thus, lowering the center of gravity effectively makes the vessel more stable and better able to resist capsizing in varying conditions, which is essential for safe navigation and operation.
