In addition to extending the investigation, what other step is recommended when assessing for hidden damage?

• A. Sound all tanks and voids
• B. Inspect exterior hull
• C. Check weather deck
• D. Notify commanding officer

Answer: (A)

When assessing hidden damage, you must quantify flooding in compartments that aren’t visible. Sounding all tanks and voids gives direct measurements of liquid levels in those spaces, revealing whether water has breached areas that look intact and whether flooding is progressing. This information is crucial for estimating remaining buoyancy, stability, and the need for pumps, countermeasures, or ballast adjustments. The process involves going to each tank and void, using a sounding instrument to determine the liquid depth, and recording the readings to detect any deviation from normal inventory. Exterior hull inspection and weather deck checks are important for surface integrity, and notifying the commanding officer is a key administrative step, but they don’t directly reveal hidden flooding.
