Master the Waves: 2025 OOW COLREGs Challenge – Navigate to Success!

WIG craft, or Wing-in-Ground effect craft, are specifically designed to take advantage of the ground effect, which occurs when they fly close to the surface of the water. This phenomenon allows them to achieve greater lift and efficiency due to the increased air pressure beneath the wings. By operating close to the water, WIG craft can achieve significant speeds while consuming less energy compared to traditional aircraft flying at higher altitudes.

The other statements do not accurately reflect the capabilities or design limitations of WIG craft. They are not confined to military use; they have potential applications in commercial transport, passenger ferries, and other areas. While conditions like high winds or rough seas can affect their operation, they are not restricted to only calm weather. Lastly, WIG craft do not require large runways for takeoff; they can often operate from relatively short strips or even from water surfaces, leveraging their unique ground effect flying capabilities.
