Q

At an angle of loll, the righting moment is __________.

🔍 Key Concepts

• Angle of loll occurs in a ship with very low or negative initial stability (GM ≈ 0 or GM < 0) • Relationship between GZ (righting lever), righting moment, and stability • Difference between positive stability, neutral stability, and negative stability on the GZ curve

💭 Think About

• Think about what the vessel is doing physically at the exact angle of loll — is it trying to come back upright, stay where it is, or roll further? • On a GZ curve for a vessel with negative GM, what is the value of GZ at the angle of loll? How does that value affect the righting moment? • Consider whether the ship at the angle of loll has any restoring or capsizing tendency at that precise angle.

✅ Before You Answer

• Remember that righting moment ∝ displacement × GZ — check what happens when GZ = 0 versus when GZ is positive or negative • Verify that an angle of loll is not the same as the angle of maximum righting arm on a normal GZ curve • Confirm whether the ship at the angle of loll is in stable equilibrium, unstable equilibrium, or neutral equilibrium and how that relates to the righting moment value
