🔍 Key Concepts

• Navigation Rules Rule 26 – Fishing Vessels (both International & Inland) • Difference between day shapes for a vessel engaged in fishing and shapes for anchored or not under command vessels • Meaning of a single black ball vs two cones with apexes together

💭 Think About

• First, recall which single shape is used for a vessel at anchor, and which combination indicates a vessel not under command. Eliminate any options that match those instead of a fishing vessel. • Look closely at which choice shows the day shape that corresponds to the red-over-white or green-over-white fishing lights at night in Rule 26. • Ask yourself: when you hear the phrase "a vessel engaged in fishing" in the Rules, what specific day shape wording is used? Match that exact wording to the illustration.

✅ Before You Answer

• Verify in Rule 26 that a vessel engaged in fishing (daytime) shows a pair of shapes arranged vertically in a particular way. • Confirm that a single black ball is associated with anchored status, not fishing, so any option that is only one ball should be ruled out. • Make sure the option you pick shows two cones with their apexes together and not balls or a ball‑diamond‑ball combination.
