What pattern colors is a vessel engaged in fishing?

• A. Green-White
• B. Red-Green
• C. White-Red
• D. Red-White

Answer: (D)

Pattern colors signal a vessel’s activity at night, and a fishing vessel uses two lights in a vertical line with red above white. This red-over-white arrangement identifies that the vessel is engaged in fishing operations, helping nearby ships assess potential maneuvering restrictions and take appropriate action to avoid gear or nets. The other color patterns do not indicate fishing: they either reflect standard navigation lights for other vessel types or different statuses, whereas red over white specifically denotes a fishing operation.
