At all angles of inclination, which is the true measure of a vessel's stability?

Question 1 of 27070

At all angles of inclination, which is the true measure of a vessel's stability?

🔍 Key Concepts

• Initial stability vs. overall stability (small angles vs. all angles of heel) • Relationship between metacentric height (GM), righting arm, and righting moment • How a vessel’s displacement interacts with its ability to return to upright

💭 Think About

• Ask yourself: which quantity actually tells you how strong the vessel’s tendency to return upright is at ANY given angle of heel? • Think about which option is valid only at small angles of inclination, and which one still describes stability at large angles (e.g., 30°, 40°, 60°). • Consider what must be combined with the righting arm (GZ) to express the vessel’s real ‘power’ to come back upright.

✅ Before You Answer

• Identify which term is defined as a measure of the vessel’s ability to return to the upright at a specific angle. • Separate the concept of initial stability at small angles from stability at large angles of heel. • Verify which option depends on both displacement and the lever arm (GZ) to represent stability.
