Waterfowl and boats moving across the surface of water produce a wake pattern, first explained mathematically by Lord Kelvin and known today as the Kelvin wake pattern. [ 1 ] This pattern consists of two wake lines that form the arms of a chevron, V, with the source of the wake at the vertex of the V.

The divergent waves are observed as the wake of a ship with a series of diagonal or oblique crests moving outwardly from the point of disturbance. These waves were first studied by William Thomson, 1st Baron Kelvin , who found that regardless of the speed of the ship, they were always contained within the 39° wedge shape (19.5° on each side ...
As the vessel exceeds a speed-length ratio of 1.34, the wavelength is now longer than the hull, and the stern is no longer supported by the wake, causing the stern to squat, and the bow to rise. The hull is now starting to climb its own bow wave, and resistance begins to increase at a very high rate.
A Kelvin wave is a wave in the ocean, a large lake or the atmosphere that balances the Earth's Coriolis force against a topographic boundary such as a coastline, or a waveguide such as the equator. A feature of a Kelvin wave is that it is non-dispersive , i.e., the phase speed of the wave crests is equal to the group speed of the wave energy ...
Another more restrictive proposal, authored by Sen. Andres Jacque (R-De Pere), would have prohibited wake surfing on a lake smaller than 1,500 acres, required wake-enhanced boats to operate at ...
Wake has not interpreted the new state law’s wording about supplementary material as applying to school library books. Third graders search for books during the WAKE Up and Read event in Garner ...
As the bow wave spreads out, it defines the outer limits of a ship's wake. A large bow wave slows the ship down, is a risk to smaller boats, and in a harbor can damage shore facilities and moored ships. Therefore, ship hulls are generally designed to produce as small a bow wave as possible.
