During what activities must WIG crafts comply with the Rules of this Part as a power-driven vessel?

WIG (Wing in Ground effect) crafts are considered power-driven vessels when they are operating in a specific mode, which is when they are in flight near the surface. In this operating mode, they maneuver similarly to conventional power-driven vessels and are subject to the same regulations outlined in the COLREGs. This includes adhering to navigation rules, ensuring safe passage, and avoiding collisions, just as a power-driven vessel would.

When a WIG craft is in flight near the surface, it generates lift and can travel efficiently while being close to the water. It's crucial for these vessels to comply with the COLREGs during such operations to promote safety and prevent accidents, as they may encounter other vessels and obstacles in the waterway during this phase.

In contrast, when a WIG craft is anchored, undergoing maintenance, or stationary in the water, its status does not classify it as a power-driven vessel in motion. Therefore, it doesn't need to follow the same navigation rules that govern vessels actively maneuvering in the water.
