Loading cargo above the vessel's center of gravity will increase the vessel's vertical center of gravity. How will this affect the vessel?

🔍 Key Concepts

• Metacentric height (GM) and what it says about initial stability • Relationship between stability and a vessel’s rolling period (how fast or slow she rolls) • Effect of raising the vertical center of gravity (KG) on overall stability

💭 Think About

• When you load weight high and raise KG, are you making the vessel more or less stiff (stable)? • Does a very stable, ‘stiff’ vessel roll quickly or slowly compared to a tender, less stable vessel? • Think about extreme cases: a barge with very strong stability vs. a top‑heavy yacht in a seaway—whose roll is snappier and whose is slow and lazy?

✅ Before You Answer

• Decide first: does raising the vertical center of gravity increase or decrease stability? • Then decide: does increasing stability make the roll period longer or shorter? • Match the choice that correctly pairs the direction of stability change with the direction of roll‑period change.

Question 1 of 27070

Loading cargo above the vessel's center of gravity will increase the vessel's vertical center of gravity. How will this affect the vessel?

If your vessel's stability is increasing, the rolling period will increase

If your vessel's stability is increasing, the rolling period will remain the same

If your vessel's stability is decreasing, the roll period will increase

If your vessel's stability is decreasing, the rolling period will decrease
