What is the flashing sequence of a west cardinal buoy?

• A. 1 short every sec
• B. 3 short every 10 sec
• C. 9 short every 15 sec
• D. 6 short, 1 long every 10 sec

Answer: (C)

The flashing sequence of a west cardinal buoy is characterized by a specific light pattern designed to convey navigational information to mariners. The correct answer reflects that the west cardinal buoy exhibits a sequence of 9 short flashes in a duration of 15 seconds. This flashing pattern is designed to notify vessels that they should keep the buoy on their starboard side when navigating the area.

The design of these light sequences is essential for safe navigation, indicating the buoy's position and indicating safe passage on the east side by keeping the buoy to the right when approaching from the north. Understanding this pattern helps boaters prevent potential hazards, especially in unfamiliar waters or areas with navigational challenges.

Other patterns do not correspond to the distinctive identification system used for cardinal buoys and would confuse the regulations of safe navigation, which rely on precise and universally recognized signals. This knowledge is fundamental for anyone operating pleasure crafts and aiming for safe boating practices.
