🔍 Key Concepts

• Subdivision and damage stability – how many compartments can flood while the vessel still remains afloat and stable • Difference between simply "having" compartments and being designed to withstand flooding of compartments • What "two-compartment" implies about survivability if flooding occurs in more than one space

💭 Think About

• Ask yourself: does the term describe the number of physical compartments, or the level of safety against flooding? • Think about what it would mean, in practice, for a vessel that is safe even if multiple compartments are flooded – how would designers describe that? • Compare each choice: which one clearly ties the phrase "two-compartment vessel" to damage tolerance rather than just layout or count of rooms?

✅ Before You Answer

• Confirm which choices talk about flooding survivability, not just how the vessel is arranged internally • Check whether the option describes the vessel remaining afloat versus sinking under certain flooding conditions • Eliminate any answer that merely counts compartments without mentioning flooding or staying afloat
