Under the IALA-B Buoyage System, which is TRUE of a buoy displaying a red light?

🔍 Key Concepts

• IALA-B lateral system (Region B used in the Americas, Japan, Korea, Philippines) • Meaning of red lateral marks when entering from seaward • Differences between shape/lettering vs. light color and characteristics

💭 Think About

• Think about what red buoys mark in IALA-B when a vessel is coming IN from the sea: which side are they kept on? • Which of the options describes something that is always true for any buoy showing a red light, not just sometimes true? • Ask yourself whether the light color (red) automatically means a specific light pattern like Morse code, or just defines the side of the channel.

✅ Before You Answer

• Verify the rule: in IALA-B, remember the phrase used to help mariners keep red buoys on a particular side when returning from seaward. • Check whether all red-light buoys must be lettered, or if numbering/lettering depends on buoy purpose and local system. • Confirm whether a red light tells you about which side to pass on, rather than requiring special equipment like a radar reflector or a specific Morse code pattern.
