BOTH INTERNATIONAL & INLAND You are on watch and sight a vessel showing a high intensity all-round flashing red light. What does this light indicate?

🔍 Key Concepts

• Special flashing red lights in the Navigation Rules • Where WIG (Wing-In-Ground) craft are mentioned in the Rules • Difference between work lights (like dredging/cable) and special all-round signals

💭 Think About

• Look in the Navigation Rules Annexes and Part C (Lights and Shapes) for any reference to a high intensity all-round flashing red light—what type of craft is linked to that exact phrase? • Ask yourself: do dredging, fishing, or cable-laying vessels normally show combinations of red, white, green in specific patterns instead of a single all-round flashing red? • Consider which of these vessel types would need a very conspicuous, unique signal only during a specific phase of operation (like taking off or landing).

✅ Before You Answer

• Verify which option (if any) is explicitly tied in the Rules to a high-intensity all-round flashing red light by name. • Confirm whether dredging, fishing, or cable-laying vessels instead show pairs or groups of steady (non‑flashing) lights rather than a single flashing red. • Check that the light is described as all-round, red, and flashing (not yellow, not white, not a group of lights) and match that exact description to one vessel type.
