Q

You see a buoy with red and green bands. What does this buoy indicate?

🔍 Key Concepts

• Lateral buoyage system (IALA B in the U.S.) and what red vs green marks mean • Meaning of a buoy that has both red and green horizontal bands instead of just one color • How aids to navigation mark a preferred channel at a junction

💭 Think About

• Ask yourself: when two channels meet or split, how does the buoy tell you which side is the preferred (main) channel? • Think about what the topmost color band on a red/green buoy tells you in terms of which side to pass on when inbound from seaward. • Compare what marks an isolated danger or the exact centerline of a channel versus what marks a junction where one channel is favored.

✅ Before You Answer

• Verify which buoy type uses red and green horizontal bands in the U.S. lateral system (IALA B). • Confirm that an isolated danger mark and a safe water/center channel mark each have different colors and patterns than a banded red/green buoy. • Check how the top color band indicates whether the preferred channel is to port (left) or starboard (right) when returning from sea.
