Q

INTERNATIONAL ONLY You have sighted three red lights in a vertical line on another vessel dead ahead at night. Which vessel would display these lights?

🔍 Key Concepts

• International Rules only – some light configurations exist only under the International Rules • Compare light patterns for a vessel constrained by her draft (Rule 28) vs. a vessel aground (Rule 30) • Difference between lights for a vessel moored/at anchor and those for other special conditions

💭 Think About

• Look up how many all-round red lights a vessel aground shows at night, and compare that to the number given in the question • Check which vessel type is specifically defined as International only and uses three all-round red lights in a vertical line • For each option, mentally sketch the light pattern that vessel should show and see which exactly matches “three red lights in a vertical line”

✅ Before You Answer

• Verify under the International Rules which vessel shows three all‑round red lights in a vertical line (note: not two) • Confirm whether a vessel aground uses the same number of red all‑round lights as in the question • Make sure you distinguish between shapes by day (balls, cylinders, diamonds) and lights by night so you don’t mix them up
