As chief engineer you should understand the concept of loll and its cause. An angle of loll is commonly caused by which of the following conditions?

🔍 Key Concepts

• Angle of loll and how it differs from normal heel or list • Relationship between GM (metacentric height) and initial stability • Effect of free surface and movement of G (center of gravity) on stability

💭 Think About

• First, recall what happens to a vessel’s stability curve when GM becomes very small or negative. How does the ship behave when upright? • Think about whether an angle of loll appears suddenly due to an outside push (like wind) or whether the ship "seeks" a new equilibrium angle by itself. • Consider whether an angle of loll is primarily about an external force holding the ship over, or an internal stability problem making the upright position unstable.

✅ Before You Answer

• Verify whether angle of loll is an equilibrium position with no external heeling moment acting. • Check which option directly describes a condition of initial instability at small angles of heel. • Confirm whether free surface alone, with G still below M, creates an angle of loll, or just reduces but does not reverse stability.
