🔍 Key Concepts

• list vs. trim and what causes each motion • relationship between center of gravity (G), center of buoyancy (B), and the point about which a vessel rotates for small angles • how a floating body's rotation point differs from where weight and buoyant forces act

💭 Think About

• When a vessel or MODU heels or trims slightly, which point tends to stay nearly fixed in the water while the hull rotates around it? • Is list/trim primarily about where the weight acts (G), where the buoyant force acts (B), or about the geometric pivot of the waterplane? • Think about drydocking: when a ship first takes the blocks, what point is used to describe changes in trim as the draft changes?

✅ Before You Answer

• Be clear on the definitions of center of gravity, center of buoyancy, and center of flotation—they are not the same point • Ask which point lies in the waterplane area rather than in the full underwater volume • Recall that list and trim are rotational motions (heel and pitch), so focus on the point that acts as the pivot for these rotations
