🔍 Key Concepts

• These are standard naval architecture symbols used on hull lines and loading diagrams • Consider what part of the ship or measurement is located at the very middle in the fore‑and‑aft direction • Think about how symbols might use paired or mirrored shapes to suggest a central position

💭 Think About

• Which of the answer choices refers to a position along the length of the vessel rather than a line or a quantity? • Why might a symbol made of two overlapping circles be chosen to represent that particular position or concept? • Which options are clearly something else, like a reference line or a weight/volume quantity, and therefore do NOT fit this symbol?

✅ Before You Answer

• Eliminate choices that describe a measurement of weight or volume, not a location • Eliminate choices that are clearly a single reference line (used as a datum when drawing the ship) • Ask yourself: does this symbol’s shape suggest being in the center between bow and stern?
