Which additional day-shape must you show on the forward end of an inconspicuous partially submerged vessel or object being towed more than 200 meters in length?

• A. Two black spheres arranged vertically
• B. Two black balls arranged vertically
• C. One black ball
• D. Three black balls arranged vertically

Answer: (B)

In tow situations, day shapes warn other vessels about what you’re carrying and how it extends in the water. When a vessel or object being towed is inconspicuous and partially submerged, and the length of the tow exceeds 200 meters, you must display a specific sign at the forward end of the towed item to indicate the long tow. The required sign is two black balls arranged vertically. This two-ball vertical arrangement is the standard signal that a vessel or object is being towed. The length threshold of more than 200 meters triggers the need to show this shape at the forward end so approaching vessels can anticipate the long tow and exercise caution. Other shapes do not match this exact signaling purpose for a long tow, which is why the two-ball vertical symbol is the correct choice.
