Q

When outbound from a U.S. port, what does a buoy displaying a flashing red light indicate?

🔍 Key Concepts

• IALA Region B buoyage system used in the U.S. • Meaning of red flashing lights on lateral buoys when inbound vs outbound • The memory aid "red right returning" and what changes when you are leaving a U.S. port

💭 Think About

• Think about which side of the channel red buoys mark when you are RETURNING from sea. Now mentally reverse that situation when you are DEPARTING a port. • Ask yourself: If a red buoy should be kept on your starboard side when inbound, which side of the channel does that same buoy represent when you are outbound? • Consider whether flashing red on a lateral buoy by itself indicates a wreck, a turn, or a preferred channel, or if those require additional shapes/colors or light characteristics.

✅ Before You Answer

• Confirm that in the U.S. (IALA B) red buoys are kept to starboard when returning from sea. • Verify whether preferred channel marks (junction buoys) use a simple red light alone, or if they have banded colors and specific light rhythms. • Check if an isolated danger (like a wreck) or a sharp turn is normally marked by a plain lateral red buoy or by a different type of mark/light pattern.
