🔍 Key Concepts

• Trim vs. List vs. Inclination – understand what a port aft inclination tells you about weight shift on the vessel • Tank locations and numbering – how "1P, 9P, 10P, 10S" relate to fore/aft position (forward vs aft), side (port vs starboard), and height • Effect of dropped casing – how a local hull/tank breach near where the casing fell would affect which tank floods and the vessel’s list/trim

💭 Think About

• If the port aft inclination is slowly increasing, what does that say about where extra weight (water) is entering: forward or aft, port or starboard? • Compare which of the listed tanks are on the port side and which are aft. Which one best matches the place where casing was dropped (port side, aft)? • Think about why the inclination is slowly increasing rather than sudden. What kind of damage/flooding pattern would cause a gradual change rather than an immediate list?

✅ Before You Answer

• Verify which side is port (P) and which side is starboard (S) in the tank labels • Check the longitudinal numbering of tanks on Sample Form #4: do higher numbers correspond to more aft locations? • Confirm which of the answer choices is both on the port side and located aft, consistent with the observed port aft inclination.
