Q

Which buoy may be odd numbered?

🔍 Key Concepts

• Lateral buoyage system (IALA B in the United States) and how numbers increase when returning from seaward • Difference between nun buoys (red, conical) and can buoys (green, cylindrical) • How mid-channel/SAFE WATER buoys are marked (colors, shapes, letters vs. numbers)

💭 Think About

• Think about which side of the channel uses odd numbers and what color/shape buoys are found on that side • Ask yourself: are mid-channel buoys treated like side marks with odd/even numbers, or are they marked in some other way? • Consider whether unlighted vs. lighted changes the numbering rule, or if the rule depends mainly on the buoy’s purpose and side of channel

✅ Before You Answer

• Confirm which color/shape buoys carry odd numbers when returning from sea in the U.S. system • Verify how mid-channel (safe water) buoys are labeled in the Light List or chart examples (numbers, letters, or both) • Make sure you separate the ideas of color/shape and lighting from the rule about odd/even numbering
