The inventive floating craft, consisting of two pontoons 1 and 2 segment profile, the rocker arm 3, the rods 6, holding the keel, and the pump 8, the articulated hinge. Kiel 7 consists of two beams immersed to a depth of 1/3 and 2/3 the length of the maximum wavelength for a given area. 1 C.p. f-crystals, 1 Il. The invention relates to energy as one of the options for the use of energy derived from wave generation in the water.Known design snap Cockerell raft , which consists of three pivotally connected pontoon, profiling the surface of the waves.The disadvantages of the device must be attributed to the rough contour of the waves and the rigidity of the structure, leading to its weighting, i.e., more inertia and therefore less effective.It is known device  to convert wave energy into an electrical pulse that contains a raft of two floats, connected rigidly interconnected by a link in the middle of which hinged rod ballast is entrusted anchored ballast cargo and this reduces the amplitude of the swing arm.The purpose of the invention is the elimination of these disadvantages, reaching to the fact that the oscillation of the water surface (wave) is captured using two pontoons segment shape, height 1/2 R and rounded nose underwater part. The pontoon has a horizontal axis that is located on the lower plane and pivotally connected with the rocker.The pontoons are spaced from each other at a distance of half the length of the optimal wavelength for a given area.In order to withstand the shock of a steep wave pontoon has a 200% reserve buoyancy, and therefore a small frontal resistance, which accomodates rotation of the pontoon on its axis, providing a full profile of the contour of the different waves of the spectrum, thereby increasing the efficiency of the device.The drawing shows a side view of the device.The wave Converter is a floating tool composed of two pontoons 1 and 2, has a relatively shallow draft, in the range of 0.2 R (where R is the radius of the generatrix of the upper surface of the pontoon) and attached to the arm 3 by means of hinges 4 and 5. The arm 3 is articulated with 6 bar holding the keel 7, consisting of due 6 on mobile connections attached piston pumps 8.Wave Converter operates as follows.When the surging waves of the pontoon 1 turns on the axis 4, profiling the ascending surface, picks up the edge of the rocker 3, unfolding against the rod 6, which remains horizontally stationary immobile keel 7, t-beams on which the thrust area of each comparable to the mid-section of the pontoon and are at a depth greater than half the length of the maximum wave, where disturbance of the water surface does not exert its influence. Rotation of the rocker arm 3 moves the piston pumps 8, which pumps water into a common header, uniting battery such converters, until the cumulative capacity.Accumulated water from the tank is spent on domestic needs or converted into another form of energy without environmental consequences. 1. Wave Converter comprising two pontoons connecting their rocker, rod with a keel and piston pumps, hinged to the node device, wherein the pontoons are made in the form of segments with a height equal to half the radius of the generatrix, have a 200% reserve buoyancy and have the axle centre, located on sharedinstance for this area.2. The Converter according to p. 1, characterized in that the device has a keel, composed of two parallel Tauri beams, respectively installed at depths of 1/3 and 2/3 of the maximum wavelength, and each beam has a hard surface is not less than the area of the midsection of the pontoon.
