🔍 Key Concepts

• Understand the difference between the deck line and the various load line marks (Plimsoll and seasonal marks). • Recall what the Plimsoll mark looks like (circle with a horizontal line) versus a single horizontal line on the ship’s side. • Know where the Winter North Atlantic and Fresh Water load lines are usually placed relative to the Summer load line on the standard load line grid.

💭 Think About

• Look closely at mark A: Is it part of the circular Plimsoll symbol or the grid of seasonal lines, or is it a separate, single line by itself? • Ask yourself which marking on a ship’s side is used to show the position of the freeboard deck, and which markings are used to show maximum allowable draft in different seasons and water types. • Consider: would a special condition like Winter North Atlantic normally be shown as a lone line far away from the main load line grid, or as one of several lines tied to the Plimsoll circle?

✅ Before You Answer

• Verify which option corresponds to the circle with a horizontal line – that one is not mark A in this illustration. • Identify which marking in the diagram shows a single, isolated horizontal line near the top – match that with the term that describes the freeboard deck reference line. • Make sure you can distinguish between seasonal load lines (a group of parallel lines connected to a vertical line) and any separate structural reference line on the hull.
