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 ...
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 ...
This underlies the Kelvin wake pattern for the bow wave of all ships and swimming objects. Regardless of how fast they are moving, as long as their velocity is constant, on each side the wake forms an angle of 19.47° = arcsin(1/3) with the line of travel. [7
An ordinance passed Jan. 15 to prohibit wake-enhanced boating on two lakes in the Waupaca Chain O' Lakes is being challenged. The town will hold a meeting Monday on the matter.
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 ...
Wheat berries, a nutty-tasting whole grain with a pleasantly chewy texture, are the base of this hearty breakfast bowl recipe. The fiber-rich grain freezes very well, so cook up a batch to stash ...
