What primarily defines a power-driven vessel?

A power-driven vessel is primarily defined as a vessel that is propelled by machinery. This category includes boats and ships that utilize engines for propulsion, allowing them to move through the water independent of natural forces like wind or current. By contrast, a sailing vessel relies on wind for propulsion, making it distinctly different from a power-driven vessel. Similarly, vessels designed solely for towing and human-powered vessels like kayaks or canoes do not fall under the definition of a power-driven vessel since they use different means for movement. Understanding this classification is crucial for recognizing the various types of vessels and their operational characteristics on the water.
