What occurs when surf riding happens to a vessel?

When surf riding occurs, a vessel experiences a specific interaction with the waves that allows it to ride on the forward face of the wave. This phenomenon typically happens when the speed of the vessel approaches the speed of the wave itself. As the vessel moves into the wave, it can gain momentum and accelerate due to the energy transferred from the wave.

In this situation, the vessel essentially gets propelled by the wave, which causes it to move faster, often matching or exceeding the speed of the wave. This dynamic relationship is what characterizes surf riding, distinguishing it from other forms of movement through water where the vessel might not experience such an increase in speed. The conditions necessary for surf riding typically occur with moderate to large waves and certain hull designs that are favorable for this type of maneuvering, allowing for the vessel to utilize wave energy effectively.
