Your vessel is listing because of a negative GM. To lower G below M, which action should you take?

Question 1 of 27070

Your vessel is listing because of a negative GM. To lower G below M, which action should you take?

🔍 Key Concepts

• Metacentric height (GM) and what a negative GM means for stability and list • Effect of raising vs lowering the center of gravity (G) on vessel stability • How adding, removing, or shifting weight vertically and transversely affects G and list

💭 Think About

• First, recall what happens to GM when G moves up versus when G moves down. For a negative GM, where is G relative to M? • Look at each choice and decide: does this action move G up or down, and does it also shift G toward the high side or toward the low side? • Ask: which action both helps correct the list AND moves G in the direction that makes GM less negative (more stable)?

✅ Before You Answer

• For each option, sketch a simple cross-section and mark G and M before and after the action. • Verify whether the option changes G vertically (up or down), transversely (toward high or low side), or both. • Identify which option actually lowers G below M instead of raising G or only shifting G sideways.
