🔍 Key Concepts

• Look at the exact shape shown: two cones with their apexes together (like an hourglass). • Review Navigation Rules Rule 26 – Fishing Vessels, especially the day shapes these vessels show. • Compare with other shapes: tow over 200 m (single diamond), vessel not under command (two balls), and restricted in ability to maneuver/underwater work (ball–diamond–ball).

💭 Think About

• Which vessel type, according to Rule 26, is required to display two cones apex-to-apex during the day? • Which of the answer choices would instead use balls or a diamond in its day shape, and can therefore be eliminated? • Ask yourself: if you saw this hourglass shape by day, what kind of fishing gear or operation is it meant to warn you about?

✅ Before You Answer

• Verify in the diagrams that a tow over 200 m uses a single diamond, not cones. • Confirm that not under command is shown by two black balls in a vertical line. • Check that restricted in ability to maneuver/underwater work uses the ball–diamond–ball pattern, which is different from the two cones in the illustration.
