BOTH INTERNATIONAL & INLAND Which display of lights shown in illustration D072RR below indicates a dredge underway and not dredging?
AI Explanation
The correct answer is B.
The display of lights shown in illustration D072RR that indicates a dredge underway and not dredging is B. This is because the International and Inland Navigation Rules (Rule 27) state that a vessel engaged in dredging or underwater operations shall display the lights and shapes prescribed for a vessel constrained by her draft, which is a different set of lights than those shown in option B.
The other options (A, C, and D) do not correctly depict the lighting configuration for a dredge underway and not dredging, as they either show the lights for a vessel constrained by her draft or a vessel engaged in dredging operations.
