Which craft is considered a "power-driven vessel" under the Rules of the Road?

A "power-driven vessel" is defined as any vessel that is propelled by machinery. This includes vessels powered by engines that enable them to move independently of the natural forces, such as wind or current.

While sailing vessels rely on wind for propulsion and kayaks are typically human-powered, a vessel powered by an engine falls squarely within the category of power-driven vessels. The rules distinguish these vessels because their method of navigation and operation differs significantly from those that rely on non-mechanical power. Understanding this classification is crucial for safe navigation on the water, as the rules of the road apply differently to various types of vessels based on their power source.

Consequently, recognizing that only a vessel powered by an engine qualifies as a power-driven vessel clarifies the distinction of vessel types when learning maritime navigation rules. Thus, the answer encompasses only the relevant option, while the others represent different forms of vessels that do not fit the definition of power-driven.
