🔍 Key Concepts

• KG (height of center of gravity) and how removing weight from high up affects it • GM (metacentric height) and its relationship to KG and KB • Difference between reserve buoyancy (volume above waterline) and underwater buoyancy (KB)

💭 Think About

• When you take heavy containers off the deck (high above the keel), what happens to the ship’s overall center of gravity (KG) — does it move up or down? • If KG moves, how does that change GM (metacentric height), given the basic stability relationship GM = KM − KG? • Does removing cargo from on deck change the underwater shape or volume of the hull at a given draft enough to alter KB, or does it mainly change the weight distribution?

✅ Before You Answer

• Be clear where on-deck containers are located relative to the ship’s center of gravity (high or low). • Recall that reserve buoyancy depends on the above-water volume of the hull, not on the weight distribution inside or on deck. • Remember that KB (center of buoyancy above keel) is linked to the underwater volume and shape, while KG depends on where the ship’s weight is placed.
