What light must a WIG craft exhibit when taking off, landing, and flying near the surface?

A WIG (Wing-In-Ground) craft is required to exhibit a high-intensity all-round flashing red light when taking off, landing, and flying near the surface. This requirement is in place for safety and visibility, ensuring that other vessels and aircraft can easily identify the WIG craft in various conditions. The high-intensity aspect of the light serves to improve its visibility, especially during critical phases such as takeoff and landing.

The use of a red light is significant because it indicates a craft that may be operating in the vicinity of other watercraft, where caution is necessary. Red lights are commonly associated with warnings in various maritime contexts, which signals to others the potential for unusual operations or maneuvers.

In contrast, the other options do not fulfill the specific needs for visibility and safety associated with a WIG craft during its critical phases. For example, an all-round white light is often used for general visibility or for vessels that are at anchor, while a steady green light typically signifies a vessel that is sailing. An all-round flashing yellow light could indicate a different type of warning or operation but does not meet the requirements for a WIG craft in this scenario. Therefore, the high-intensity all-round flashing red light is the appropriate choice
