Question 704 Rules of the Road

The correct answer is A) being towed. The shape shown in illustration D013RR depicts the combination of two shapes - a diamond shape over a ball shape. This combination of shapes is the appropriate signal to display when a vessel is being towed, as per the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules. The other answer choices are incorrect because a vessel displaying this signal is not anchored (B), fishing (C), or towing another vessel (D). The diamond over ball shape is specifically used to indicate that the vessel is being towed by another vessel.
