An unstable upright equilibrium position on a vessel means that the metacenter is in which location?

🔍 Key Concepts

• Metacenter (M) vs center of gravity (G) and how their relative vertical positions affect stability • Meaning of stable, neutral, and unstable equilibrium in terms of GM (metacentric height) • What happens to a vessel after a small heel when it is unstable upright

💭 Think About

• Think about what sign (positive, zero, or negative) GM has when a vessel is in unstable upright equilibrium. • Ask yourself: for the vessel to be unstable, does the metacenter need to be above, below, or at the same height as the center of gravity? • Relate each choice to whether it tells you anything about the vertical relationship between M and G that would make GM negative.

✅ Before You Answer

• For each option, check if it clearly describes M being above, below, or at the same height as G. • Verify which situation gives a negative GM, meaning the vessel will continue to heel after being disturbed rather than returning upright. • Eliminate any options that talk about position relative to something other than G when the question is about upright equilibrium stability.
