🔍 Key Concepts

• Navigation Rules Rule 25 – Sailing vessels underway (optional all-round lights) • Navigation Rules Rule 26 – Fishing vessels (red over white or green over white combinations) • Navigation Rules Rule 27 – Vessels engaged in mine clearance (three all-round green lights in a cross)

💭 Think About

• Look carefully at how many all-round lights are in a vertical line and what their colors and order are. Which vessel type has a well-known rhyme to remember that specific red/green order? • Notice that there is also a separate green light off to the side. What normal navigation light could that represent on a vessel underway? • Compare the pattern in the picture with the required light combinations for fishing, mine clearance, pilotage, and sailing. Which one uses an optional pair of all‑round lights in addition to regular sidelights and sternlight?

✅ Before You Answer

• Count the vertical lights and confirm the color order from top to bottom. • Decide whether the lights in a vertical line are all‑round lights or normal sidelights/masthead lights. • Verify in Rule 25, 26, and 27 which vessel type may show red over green in a vertical line when underway, along with normal sidelights.
