🔍 Key Concepts

• Angle of loll and what it tells you about the vessel’s stability at that heel angle • Relationship between GZ (righting arm), GM (metacentric height), and whether the vessel is stable, neutral, or unstable • How GZ behaves when a vessel passes from upright through angles of heel into a condition of stable vs unstable equilibrium

💭 Think About

• At an angle of loll, is the vessel in stable, unstable, or neutral equilibrium at that specific heel angle? What does that imply about GZ at that angle? • If you plotted a GZ curve against heel angle, where would the angle of loll appear in relation to the point where the curve crosses the horizontal axis? • Think about what the sign (positive or negative) of GZ means physically: is the vessel being pushed back upright or further over at the angle of loll?

✅ Before You Answer

• Be clear whether angle of loll occurs with initial GM negative and how that affects GZ near small angles • Remember: positive GZ means a restoring moment, negative GZ means an overturning moment, and zero GZ means no net heeling or righting moment at that exact angle • Verify whether, in the absence of external forces, the vessel is experiencing any net righting or heeling moment at the angle of loll itself
