What is referred to as the 'wake' of a vessel?

The term 'wake' specifically refers to the trail of waves generated by a moving vessel. As a boat moves through the water, it displaces water, creating waves that flow outward from the hull. This phenomenon is crucial for various reasons, including navigation safety and the environmental impact of a vessel's movement. The wake can influence other boats, shoreline structures, and even affect marine life, therefore understanding this concept is vital for safe boating practices. The other options relate to different aspects of boating but do not define what a wake is.
