In addition to other lights, a fishing vessel must display a light in the direction of its gear extending outward more than 150 meters. What color is this light?

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

Answer: (C)

The key idea is that fishing vessels with gear extending out more than 150 meters must show a dedicated light in the direction of that gear to warn other vessels. The color of this gear light is white. White is used for signaling important visibility hazards or gear location, making it easy to spot at sea and not confusing with the red and green navigation lights that indicate a vessel’s port and starboard sides. This white gear light specifically marks the location of the gear itself, so other vessels can steer clear and avoid entanglement. Blue is not used for this purpose, and red or green lights serve different signaling roles tied to the vessel’s direction.
