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

WIG (Wing In Ground) crafts must comply with the rules as a power-driven vessel when they are in flight near the surface due to their operational characteristics. When a WIG craft is in this mode, it is essentially traveling above the water while still benefiting from ground effect, which influences its speed and maneuverability. As a power-driven vessel, it is subject to the same navigational rules and responsibilities as other vessels operating in similar circumstances, ensuring safety on the water.

In contrast, the other scenarios do not require compliance with the rules specific to power-driven vessels. When anchored or stationary, a vessel’s responsibilities may differ, often involving different sets of requirements or rules pertinent to vessels at anchor or not under command. Similarly, while conducting maintenance, the focus is not on navigation but on operational safety, thus differing from the operational criteria that necessitate adherence to power-driven vessel rules.
