What is the significance of a ship's center of gravity?

• A. It affects speed and maneuverability
• B. It determines the ship's color and aesthetics
• C. It affects stability and can lead to capsizing
• D. It indicates the amount of cargo that can be carried

Answer: (C)

The center of gravity of a ship is a crucial factor in its stability and overall safety at sea. When the center of gravity is located above the center of buoyancy, the ship is more prone to tilting or heeling. If the center of gravity shifts due to loading, unloading, or changes in cargo arrangements, it can result in a situation where the ship may capsize if the balance is disrupted significantly.

A stable vessel must have an appropriate balance between its center of gravity and center of buoyancy to ensure that it remains upright and can recover from heeling forces, such as those created by waves. When these elements are correctly aligned, the ship will return to an upright position; however, if the center of gravity is too high or shifts unexpectedly, the risk of capsizing increases significantly, making this a vital aspect of ship design and operation.
