When a space is flooded, which action helps maintain the ship's stability?

• A. Open the sea chest to release water
• B. Pump water from the space to ballast tanks
• C. Increase propulsion to control movement
• D. Counterflooding to balance trim.

Answer: (D)

When a space floods, the ship tends to heel toward the flooded side because that side now has extra weight. To restore stability, you counteract this list by flooding ballast tanks on the opposite side. This shifts weight away from the flooded area and back toward level trim, helping to maintain stability and control. Opening the sea chest would just bring in more water and worsen stability. Pumping water from the flooded space into ballast tanks can relocate water, but without purposely placing ballast on the opposite side, it may not correct the heel. Increasing propulsion doesn’t address the weight distribution and stability issue.
