🔍 Key Concepts

• Plimsoll mark / load line marks on a vessel’s side • Order of the seasonal load lines from top to bottom • Difference between salt water and fresh water loading marks

💭 Think About

• Look at the vertical load-line grid: from the highest to the lowest horizontal lines, which seasons or water types are normally arranged in that order? • Think about whether ships can be loaded deeper in warmer / less dense water or colder / denser water, and how that affects which marks are higher or lower. • Compare where the mark labeled E sits relative to the other marks on the right-hand side — is it toward the top, middle, or bottom of the group, and which seasonal mark normally goes there?

✅ Before You Answer

• Verify the standard sequence of load line marks: TF, F, T, S, W, WNA (or equivalent) from uppermost to lowermost on the right-hand side grid. • Check carefully that letter E is not the highest or lowest mark, but see exactly how many marks are above and below it. • Confirm whether summer is used as the reference line from which other seasonal marks (tropical and winter) are spaced.
