Diagram for question 430
AI Explanation
The correct answer is B. As per the International Regulations for Preventing Collisions at Sea (COLREGS), for an inconspicuous partially submerged vessel or object being towed more than 200 meters in length, a diamond shape must be displayed on the forward end. This diamond shape serves as an additional day shape to improve the visibility of the towed object. The other answer choices are incorrect. Option A (a cone) is not the required shape. Option C (no shape) is incorrect as the regulations require the diamond shape to be displayed. Option D is also incorrect, as a day shape must be shown as per the regulations.
