In Region A of the IALA Buoyage System, when entering from seaward, the port side of a channel would be marked by which buoy?

🔍 Key Concepts

• IALA Region A vs Region B color conventions for lateral marks • Shape and color used for port-hand lateral buoys when entering from seaward in Region A • Difference between can (cylindrical) and conical (nun) buoy shapes

💭 Think About

• First, recall the general rule for which COLOR marks the port side and which COLOR marks the starboard side in Region A when coming from seaward. Which side is red, which is green? • Next, match the correct SHAPE used for a port-hand buoy: is it cylindrical (can) or pointed (conical/nun)? • Finally, combine both: what is the correct color + shape combination for a port-hand buoy in Region A when entering a channel from seaward?

✅ Before You Answer

• Be sure you’re thinking of Region A, not Region B (United States is Region B). • Confirm in your notes which side gets red and which side gets green in Region A when inbound. • Verify that you understand that can = cylindrical/flat-topped and conical = nun/pointed before matching with the answer choices.
