Q

The important initial stability parameter, GM, is which of the following?

🔍 Key Concepts

• Initial stability and what "initial" means for small angles of heel • Definitions of G (center of gravity), M (metacenter), B (center of buoyancy), and K (keel) • How the distance between specific points (e.g., G and M) affects a vessel’s tendency to return upright

💭 Think About

• Ask yourself: GM is literally the distance between which two points on the ship? Think about what G and M stand for. • Which of the answer choices describes a distance directly involving both G and M, rather than only one point and the keel? • Which vertical distance is most directly linked to how “stiff” or “tender” a ship feels in a seaway (how quickly it rights itself from a small heel)?

✅ Before You Answer

• Be sure you know that G = center of gravity, M = metacenter, B = center of buoyancy, K = keel. • Verify which option refers specifically to the vertical distance from G to M, not from G or M to the keel. • Confirm from your notes that the initial metacentric height used in stability calculations is the distance labeled GM, not KG, KM, or KB.
