A cylindrical buoy that tapers to a blunt point at the top is called which buoy?

• A. Nun buoy
• B. Can buoy
• C. Spar buoy
• D. Floating buoy

Answer: (A)

Understanding buoy shapes helps you recognize marks at a glance. A nun buoy is a cylindrical buoy that tapers upward to a blunt point at the top. This distinct profile sets it apart from other common shapes: a can buoy has a cylindrical body with a flat top, a spar buoy is a tall, slender pole-like buoy, and a floating buoy is a more generic type without a distinctive tapered form. Since the described buoy matches the cylindrical body with a taper to a blunt top, it corresponds to a nun buoy.
