🔍 Key Concepts

• Slack tank behavior (partially filled tank) during damage • Most direct method of detecting flooding or leakage in a specific tank • Difference between indirect clues (list, strainers) vs. direct measurement

💭 Think About

• Ask yourself: which option gives you a clear, quantitative indication of a change in the tank’s contents after grounding? • Which methods could be misleading or delayed, giving you information only after the situation has already worsened? • In a slack tank, what simple test would show if oil is escaping or water is entering, even before visible external effects appear?

✅ Before You Answer

• Which choice lets you compare present tank condition to previous soundings or records? • Which method allows you to detect small changes early, rather than waiting for obvious signs like a list? • Eliminate any options that rely only on indirect symptoms instead of directly checking the tank’s contents.
