wakes

A wake is a disturbance in a fluid produced by a moving object. In marine contexts, a wake refers to the pattern of waves and turbulence created behind a vessel as it travels through water. The lower-energy pattern forms a characteristic V-shaped region known as the Kelvin wake, with a broadest line of crests extending at about 19.5 degrees to the vessel’s path in deep water. The height, wavelength, and overall geometry of a wake depend on factors such as vessel speed, hull form and size, water depth, wind, and currents. Faster speeds generally generate larger, more energetic wakes. Wake behavior can be altered by shallow water, bathymetry, and coastal structures, which also influence shoreline erosion and sediment transport. In practice, wakes affect other vessels, anchored structures, and harbor operations, making wake mitigation and appropriate speed limits important in crowded waterways and channel passages. Ship design often aims to reduce wake energy through hull form, propulsion choices, and operational measures to minimize impact on surrounding traffic and infrastructure.

A wake also denotes a social gathering held after someone dies, traditionally to observe a vigil or viewing before a funeral or to recall the deceased afterward. Customs vary widely by culture and religion but commonly involve a time for attendees to pay respects, share memories, offer condolences, and sometimes participate in prayers or meals. The term originates from the idea of staying awake to honor the deceased, and in some regions it is synonymous with a viewing, visitation, or the early phase of funeral proceedings.
