Which option correctly identifies the night light configuration of a fishing vessel (not trawling)?

• A. A Diving operations
• B. A red over white light
• C. A Towing vessel
• D. A Sailing vessel

Answer: (B)

A fishing vessel that is not trawling signals with two all-round lights arranged vertically, red above white. This red-over-white pattern identifies the vessel as engaged in fishing but not trawling, and it is visible in all directions to other mariners. If the vessel were trawling, the pattern would add a third light (red over white over red). Other vessel types use different configurations—towing vessels show a towing light, sailing vessels carry standard sidelights and a stern light, etc.—so the red-over-white arrangement is the specific signal for a non-trawling fishing vessel.
