To indicate large offshore obstructions, which buoy arrangement is used?

• A. A ring of buoys
• B. A single buoy
• C. A pair of spheres
• D. A triangular pattern of markers

Answer: (A)

When you’re marking a large offshore obstruction, you want a clear, all-around warning that there is danger in every direction. Placing buoys in a circle around the hazard creates a visible perimeter, signaling mariners to stay outside the ring. It communicates that the obstruction extends beyond a single point and that there isn’t a safe corridor through the middle; you should navigate well outside the outer ring. A single buoy wouldn’t convey the extent of the danger, and other patterns don’t provide this circular perimeter warning.
