🔍 Key Concepts

• IALA Buoyage System Region A vs Region B – know which colors mark port and starboard when entering from seaward • Lateral marks – shape (can vs conical) and topmarks for port and starboard sides • Phrase: "red to port, green to starboard" – but remember this is different between Region A and B

💭 Think About

• First, recall in Region A what color marks the starboard side when entering from seaward. Eliminate any options that use the wrong color. • Next, think about the standard shape for a starboard lateral mark in the IALA system. Is it can-shaped (cylindrical) or conical (pointed)? • Match both the correct color and correct shape for a starboard-hand buoy in Region A and choose the option that has both.

✅ Before You Answer

• Verify which color is used for starboard-hand lateral marks in Region A when proceeding in the conventional direction of buoyage (from seaward in). • Confirm the standard shape (can vs conical) used for starboard marks in the IALA lateral system. • Check that your final choice matches both the correct color and the correct shape; if either color or shape is wrong, discard that option.
