Q

What does a buoy with a composite group-flashing light indicate?

🔍 Key Concepts

• IALA Maritime Buoyage System – especially lateral vs. cardinal marks • Meaning of a bifurcation (junction) buoy in channel systems • Light characteristics: what a composite group-flashing sequence usually looks like (e.g., Fl(2+1))

💭 Think About

• Think about which type of buoy needs to show that one main channel splits into another or has a preferred side at a junction. • Ask yourself: would an anchorage, fish net area, or dredging area normally need a special lateral-style light pattern, or would they use simple flashing/occulting lights? • Recall from your buoyage studies: which buoy type is specifically associated with showing the preferred channel at a fork or junction?

✅ Before You Answer

• Verify how a composite group-flashing light is written on charts (for example, Fl(2+1)R or Fl(2+1)G) and what that notation means. • Confirm which buoy category (lateral, cardinal, special, isolated danger, etc.) uses composite group-flashing to indicate a preferred channel at a junction. • Make sure you distinguish between buoys marking areas (like anchorage or fishing zones) and buoys marking channel structure (like splits or junctions).
