🔍 Key Concepts

• Progressive flooding and how water enters the vessel • Effect of hull damage location: above vs. below the waterline • How free surface effect occurs inside tanks or compartments

💭 Think About

• Think about what can happen over time if there is a hole at or just above the waterline and the vessel is rolling or loaded down. • Which of these threats is directly related to water being able to move into new spaces as the situation continues? • Which option depends mainly on water inside the vessel being able to shift, versus just wind or stability alone?

✅ Before You Answer

• Identify which choices are directly linked to water entering the hull through openings. • Separate options caused by wind or internal liquid motion from those caused by hull breaches. • Ask: which threat continues to get worse as long as water can still enter through the damaged area?
