What will happen if cargo is shifted from...

🔍 Key Concepts

• Center of gravity (G) vs center of buoyancy (B) – which one is affected when cargo is moved inside the ship? • Effect of moving weight upward on vessel stability and GM (metacentric height) • What changes when you shift cargo internally: the ship’s underwater volume or only the position of the ship’s weight?

💭 Think About

• When you move cargo from a low space to a higher deck, does this change the total underwater shape/volume of the hull, or only the vertical position of the ship’s weight? • Think about a simple example: if you lift a heavy box from the floor to a shelf on a small boat, what happens to where the boat’s weight acts (G), and what generally happens to stability (GM)? • Which point (G or B) is tied to the distribution of weight inside the ship, and which is tied to the underwater volume of the ship’s hull? That distinction is key.

✅ Before You Answer

• Identify which of the options refer to center of gravity (G) and which refer to center of buoyancy (B). • Ask: moving cargo inside the vessel, without loading or discharging, usually changes G, B, or both? Focus on which one actually moves in this situation. • Recall: When weight is moved upwards, GM usually gets larger or smaller? Be careful not to confuse GM with G itself.

What will happen if cargo is shifted from the lower hold to the main deck on the vessel?

The GM will increase

The center of gravity will move upwards

The center of buoyancy will move downward

The center of buoyancy will move up
