🔍 Key Concepts

• free surface effect and how it reduces GM (metacentric height) • How the moment of inertia of the liquid surface affects stability • Relationship between tank shape, breadth, and fill condition and free surface moments

💭 Think About

• Which factor actually causes the free surface to create a heeling/rolling moment – is it the weight of liquid or the way it can move? • Ask yourself: which option is related to the vessel as a whole rather than the tank and liquid itself? • Consider which of these variables would change the free surface moment inside a slack tank and which would leave that internal moment unchanged.

✅ Before You Answer

• Identify which choices directly affect the moment of inertia of the free surface inside the tank • Ask: does changing this factor change the free surface correction (FSC) in a stability calculation? • Distinguish between factors related to the tank/liquid system and those related to the ship’s overall displacement
