🔍 Key Concepts

• Effect of moving weight vertically on center of gravity (G) • Relationship between G, metacenter (M), and GM (metacentric height) • What actually changes when you shift cargo inside the hull: G vs B vs M

💭 Think About

• When you move weight downward inside the ship, does the ship float deeper, shallower, or the same overall? How does that affect the center of buoyancy (B)? • Which points are directly affected by moving weight: G, B, or M? Then think how that change influences GM. • Ask yourself: does simply shifting cargo inside the vessel change the underwater shape of the hull?

✅ Before You Answer

• Be clear on the definitions of G (center of gravity), B (center of buoyancy), and M (metacenter). • Verify which point (G, B, or M) moves when weight is shifted downward within the ship, assuming displacement stays the same. • Confirm how a lowering of G (while M is unchanged) affects GM.
