Question 1 of 27070

If the cause of a sudden severe list is due to negative initial stability, counter-flooding into empty ballast tanks may __________.

🔍 Key Concepts

• Initial stability (GM) and what it means when GM is negative • Effect of counter-flooding on the center of gravity (G) and center of buoyancy (B) • Relationship between G, B, and the metacenter (M) for righting vs capsizing moments

💭 Think About

• Think about what happens to a vessel that already has negative GM when you deliberately add water on the opposite side. • Does counter-flooding in this condition create a restoring (righting) moment or can it create another capsizing (overturning) moment? • Which option best matches the behavior of a vessel where the center of gravity is already above the metacenter when more weight is added off-center?

✅ Before You Answer

• Verify what negative initial stability (GM < 0) implies about the direction of the heeling moment for small angles of heel. • Consider whether counter-flooding in empty ballast tanks raises or lowers the overall center of gravity (G). • Check which choice describes an outcome that is more dangerous rather than correcting the list, given the vessel already has negative stability.
