What does the term 'power-driven vessel' refer to?

The term 'power-driven vessel' refers specifically to a vessel that uses mechanical propulsion. This includes any vessel that is propelled by engines or other mechanical means, rather than relying solely on the natural forces such as wind or human effort. In maritime context, this classification is crucial as it determines the vessel's obligations and rights under the COLREGs (International Regulations for Preventing Collisions at Sea).

Understanding this terminology is essential for navigating situations concerning navigation rules, right-of-way, and appropriate signaling requirements. For example, power-driven vessels generally have specific rules governing their operation, especially when encountering other types of vessels, to ensure safety at sea.

In essence, a power-driven vessel is distinct from those that rely on sails or human power, as they have the advantage of greater control and maneuverability, which impacts how they interact with other vessels in various navigational scenarios.
