Question 1 of 27070

When cargo is shifted from the lower hold to the main deck the __________.

🔍 Key Concepts

• center of gravity (G) and how it moves when weight is raised on a vessel • relationship between G, B (center of buoyancy), and GM (metacentric height) • effect of shifting cargo vertically within the same vessel on stability

💭 Think About

• When you move weight from a lower point in the ship to a higher point, what happens to the overall center of gravity of the ship? Up or down? • Does the waterplane shape or underwater volume of the ship change just because cargo moved inside the hull (without loading or discharging)? How would that affect the center of buoyancy? • How does raising G affect GM: does GM get larger (better stability) or smaller (reduced stability)?

✅ Before You Answer

• Be clear about the difference between center of gravity (G) and center of buoyancy (B) and which one is affected by moving internal cargo only. • Ask whether any draft or displacement change occurs when you just move cargo inside the ship—this is critical for determining what happens to B. • Review the definition of GM (metacentric height): GM = KM − KG, and think about what happens to KG when weight is shifted upward.
