(57) Abstract: The invention relates to watercraft, and in particular to ski for movement on the water. The invention consists in that the inflatable float-skis outer shell comprises an inner inflatable envelope has a top notch to build the float, and the bottom soft rib that can be used as a keel or removed inside the float in the inverted position of the shell, the inner inflatable envelope is hermetically closed through hole, between the outer and inner shells in the lower part of the float has a longitudinal element of rigidity, which can be made in the form of a set of Autonomous rigid bars, prisoners in soft capping, and in the cutout of the outer shell and the through hole of the inner inflatable shell inside the float to another in the longitudinal element stiffness installed the mount legs are placed in hard well, having a flat horizontal bottom and vertical walls. This well Rethimno connected to the edges of the cutout of the outer shell. The use of the invention allows to obtain relatively lightweight and rigid construction water ski with good operational tx2">The invention relates to crafts for fun and sport, in particular for water skiing. Known water-skiing with a pair of floats, each of which includes a rigid outer shell, an elastic inflatable inner shell, mount the legs and the element stiffness float. These jet skis are taken as the closest analogue of the invention. Known water-skiing complex in operation and is not producible in the manufacture. The technical problem which consists in simplifying the design and improving the manufacturability of the famous water ski, is solved in that in skiing, containing a pair of floats, each of which contains an inflatable elastic inner membrane, covered by an outer shell with a longitudinal rib, the mount legs and the element stiffness float, the outer casing is made of soft material with a notch at the top, the edges of which are Rethimno connected to a rigid shaft having a flat horizontal bottom and vertical walls connected to the bottom on the perimeter of the element stiffness float placed between the contacting bottom surfaces of the inner and outer shells, in the inside is oplatka, hosts mount for legs. In addition, the element stiffness float is made in the form of a set of separate rigid boards, enclosed in a soft aggregate. In Fig.1 shows the float skis, side view; Fig.2 cross-section of the float with the keel of Fig.3 cross-section of the float when it is used without keel; Fig.4 General view of the ski when swimming in them. Each ski is an inflatable float, with a soft outer shell 1 with a soft longitudinal plate 2, an elastic inflatable inner shell 3, the longitudinal element of rigidity, made in the form of Autonomous rigid longitudinal bars 4, are placed in the soft capping 5, attachment 6, placed in a hard well, having a flat horizontal bottom 7 and the vertical wall 8. Soft outer shell 1 has a protective function and gives the float to the desired streamlined shape. The top shell is made neckline 9 to be installed inside the shell of the other parts of the float. In the bottom of the shell folded edge of the bottom seam are connected in the form of a soft longitudinal plates 2, which can extend to the outside of the shell in the form of a keel (Fig.2), and when turning the shell to be placed inside the shell (Fig. is x on calm water with the use of a keel and rafting on mountain rivers, when advantageous to use the streamlined design of the ski without the keel. Elastic inflatable sheath 3 is set inside the outer shell, while the outer casing on all sides covered it. In the middle part of the inflatable shell is made through a tightly closed hole for installation of a sump with a bracket 6. Under a hermetically sealed hole refers to a hole formed disclose shell, which does not violate the integrity of this membrane. For example, the shell may have an O-shaped middle portion connected to the cylindrical bow and stern parts. To allow pressurization of the inflatable shell is provided with a tube pressurization 10, passing through the hole 11 made in the outer shell 1. Between the outer and inner shells in the lower part of the float is placed longitudinal element stiffness that increases the rigidity of the float. This item can be made in the form of a set of Autonomous rigid bars 4, is placed in a soft closure 5, and the bars and seals can be manufactured in one piece or in separate parts, for example, the closure may be made of soft material with longitudinal pockets for free placement of the plate 7 is connected around the perimeter of the vertical walls 8. It is preferable to produce the well in a single piece. The well is open from the top to the legs of the water-skier. The upper edges of the side walls of the pit Rethimno connected to the edges of the cutout of the outer shell. This can be used eyelets made in the upper parts of the walls of the well and along the edges of the neckline sheath, lace-up, as well as other available methods. To simplify illustration of the connection of the casing and the well shows the relative position 12. Attachment 6 for the legs may be made in the form of loops of the straps, adjustable in size shoes. Floats can be equipped with additional well-known means for improving the operating conditions, such as cuffs to protect the feet from water, means for emergency connect / release mounting in extreme conditions, means to hold the hands of floats if it falls out of water-skier and other means that do not affect the essence of the invention and to simplify the illustrations are not depicted on them. Before assembling the float outer casing is provided in a position corresponding to the conditions of navigation (walking), and it turned into a position in which the outside of the shell is formed of a soft to the set of the longitudinal element stiffness next, establish inside this shell inflatable membrane and then through hole inflatable shell well with bracket 6 to the stop in the longitudinal element stiffness, straighten the inner shell within the outer, dragged through the hole 11 of the tube pressurization 10, attach the upper part of the well to the edges of the cutout of the outer shell and naduvath of the inner shell. When the supercharged internal inflatable shell 3 is pressed from all sides to the outer casing 1, gives it a streamlined shape and clamped between the self and the outer casing longitudinal element stiffness and at the same time sticking the vertical wall of the well with bracket 6. This creates a relatively lightweight and rigid progoneata design of the float. The float is ready to use as skis. For walking and when the alloy is used paddles or specially trained ski poles. During disassembly, drain the air from the inflatable shell, release the fastening of the outer casing and the well and removed from the outer sheath placed in her the details. 1. SKIS FOR TRANSPORTATION ON WATER, containing a pair of floats, each of which contains an elastic inflatable inner shell, kvazichastitsy fact, that the outer casing is made of soft material with a notch at the top, the edges of which are Rethimno connected to a rigid shaft having a flat horizontal bottom and vertical walls connected to the bottom on the perimeter of the element stiffness float placed between the contacting bottom surfaces of the inner and outer shells, the inner inflatable shell has a through hole for the well is installed all the way into the element stiffness float that hosts mount for legs. 2. Skiing under item 1, characterized in that the element stiffness float is made in the form of a set of separate rigid boards, enclosed in a soft aggregate.
