🔍 Key Concepts

• Look at the vertical color combination of the two all-round lights (red over white) shown in the illustration. • Review the Navigation Rules – Annex II and Rule 26 (Fishing Vessels) for special lights of vessels engaged in fishing. • Compare this light combination with other special operations, such as vessels not under command, restricted in ability to maneuver, or transferring dangerous cargo.

💭 Think About

• What type of vessel displays a red light over a white light, all-round and in a vertical line, at night? • If that vessel is directly ahead, what is the safest general action you should take regarding its movements and your own vessel’s route? • Which of the answer choices correctly matches both the type of vessel and the appropriate precautionary action?

✅ Before You Answer

• Verify in Rule 26 that red over white, all-round, in a vertical line is associated with a specific type of vessel and activity. • Confirm that distress signals are usually flashing or signal patterns, not just a steady red over white combination. • Check that hazardous cargo transfer and vessels not under command/restricted in ability to maneuver use different red light arrangements (e.g., red over red, or red‑white‑red), not simply red over white.
