Q

Which of the listed initials is used to represent the indicator of initial stability?

🔍 Key Concepts

• Initial stability refers to the ship’s ability to resist small angles of heel, usually up to about 10–15 degrees • Know what each of these symbols means: GM, KG, KM, GZ • Understand the relationship between the ship’s center of gravity (G), metacenter (M), and the lever arm of stability (GZ)

💭 Think About

• Ask yourself: which of these terms is directly tied to how ‘stiff’ or ‘tender’ a vessel feels at small angles of heel? • Think about which quantity changes when cargo is loaded higher or lower in the ship and how that affects initial stability. • Consider which symbol represents a distance between two specific points involved in transverse stability, and which one is an angle-dependent righting lever.

✅ Before You Answer

• Be clear on the definition of GM (metacentric height) and how it relates to initial stability. • Distinguish between KG and KM: what do K–G and K–M distances each represent? • Remember that GZ is related to the righting lever at a given angle of heel, not necessarily just at the initial, very small angles.
