What is required for a power-driven vessel's engines?

For a power-driven vessel, it is essential that the engines are ready for immediate maneuverability. This requirement ensures that the vessel can respond quickly to changing conditions, such as avoiding obstacles or adjusting course to maintain safety. Immediate maneuverability helps to prevent collisions, particularly in busy or crowded waterways where quick actions are often necessary.

While having engines running at maximum capacity might seem beneficial, it does not necessarily relate to the vessel's readiness to maneuver. The key focus is on the ability to react promptly, which is why having engines ready for immediate maneuver is critical for the safety and operational effectiveness of the vessel. Therefore, being prepared for any required maneuvers—including the ability to accelerate, slow down, or change direction—enhances both navigational control and overall safety on the water.
