What does "wake" refer to in navigation?

Wake refers to the track of disturbed water that is left behind a vessel as it moves through the water. This phenomenon occurs because the hull of the ship displaces water as it moves, creating waves and turbulence. The wake is an important consideration in navigation, as it can indicate the presence of a vessel and its course. Additionally, the size and shape of the wake can vary based on the speed of the vessel, the design of the hull, and the water conditions.

Understanding what wake is can help navigators assess their surroundings, especially in congested waterways or when approaching other vessels. It provides crucial information about the speed and direction of a ship, and it can also be a safety consideration for smaller craft or shore facilities. This awareness of wake dynamics is vital for operating safely and preventing collisions or unintended wake effects on other vessels or the environment.
