Question 769 Rules of the Road

The correct answer is C) a WIG craft. A WIG (Wing-In-Ground) craft is a vessel that operates in close proximity to the surface of the water, using the ground effect to generate lift. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a WIG craft is required to display a high-intensity all-round flashing red light when underway. This is to make the vessel's presence and maneuverability known to other vessels in the area. The other options are incorrect because: A) a vessel engaged in dredging is not required to display a high-intensity all-round flashing red light, B) a vessel in distress would display different signals, and D) a vessel restricted in its ability to maneuver would display different lights, not a high-intensity all-round flashing red light.
