Q

While preparing to enter a Brazilian port, you see ahead a red and green horizontally-striped buoy. The upper band is red. What action should you take?

🔍 Key Concepts

• IALA buoyage system and which Region Brazil is in (Region A or Region B) • Meaning of a red and green horizontally-banded lateral buoy (preferred channel mark) • How the top color on a bifurcation/preferred-channel buoy tells you which side the main channel lies

💭 Think About

• First decide whether Brazil uses IALA Region A or Region B. How does that affect the meaning of red vs green when ENTERING a port? • Think about what a horizontally-striped red/green buoy indicates compared to a vertically-striped red/white safe water mark. • If the upper band is red in the applicable region, on which side should you keep red buoys when returning from sea into port?

✅ Before You Answer

• Verify that Brazil is in IALA Region B, where "red right returning" applies. • Confirm that a horizontally red/green buoy is a preferred channel (bifurcation) mark, not a safe water mark. • Use the top color rule: in the correct region, the top color tells you which side is the preferred channel when entering from seaward.
