🔍 Key Concepts

• GM (metacentric height) and what "positive GM" tells you about stability • Difference between heel, list, and loll in stability terminology • Effect of a transverse center of gravity (TCG) off the centerline

💭 Think About

• Think about what causes a vessel to take up a steady angle of inclination to one side without external forces. Which term describes that? • How does a positive GM affect whether the vessel is stable or unstable at small angles of heel? • If the TCG is to starboard, which way will the vessel tend to lean, and is that lean temporary due to an external force or permanent due to weight distribution?

✅ Before You Answer

• Make sure you can define heel, list, and loll in one short sentence each. • Confirm which condition is associated with neutral or very small GM versus clearly positive GM. • Verify whether TCG off centerline relates to a permanent inclination or one caused by outside forces (like wind or turning).
