BOTH INTERNATIONAL & INLAND At night, the lights shown in illustration D076RR would indicate a vessel engaged in which of the operations?

Correct Answer: Option B — trawling

Rule 26(b) specifies that a vessel engaged in trawling must display two all-round lights in a vertical line, green over white, or a shape consisting of two cones with their apexes together in a vertical line. These signals identify the vessel as actively engaged in fishing with gear.
