Question 11 AB01 - Able Seafarer

The Correct Answer is D **Why option D ("It will have an even number") is correct:** In the IALA Region B (Americas, Japan, Philippines, etc.) lateral system of buoyage, when proceeding in the conventional direction (entering from seaward), **nun buoys** mark the starboard (right) side of the channel. Buoys marking the starboard side are assigned consecutive **even numbers** (2, 4, 6, etc.). **Why the other options are incorrect:** * **A) It will be green in color:** In IALA Region B, buoys marking the starboard (right) side of the channel (nun buoys) are colored **red**, not green. Green buoys mark the port (left) side. * **B) It will be cylindrical in shape:** Nun buoys are characteristic of the starboard side and are **conical** (tapering to a point at the top) in shape. Cylindrical buoys (can buoys) mark the port side. * **C) It will be left to port when entering from seaward:** A nun buoy marks the **starboard** (right) side of the channel when entering from seaward. Therefore, it must be kept to your *starboard* (right) side, not your port (left) side.
