Water bicycle has hollow body with seat, load bearing member in form of V-shaped hydrofoil connected with handle-rods which are mounted on body and propulsor made in form of two tail cetacean fins. Levers, synchronizer and propulsor fins are interconnected by means of elastomer joints. Body, wing and fins are made from composite materials.

Proposed dismountable assembled submersible vehicle includes dismountable assembled catamaran with side inflatable sectional floats, portable house mounted above them and manned submersible vehicle located in between them and suspended from catamaran by means of winch-and-rope system controlled from submersible vehicle. Proposed complex includes also ramp-frame mounted above floats and inclined by means of inflatable mat and provided with built-in rolls for lateral lowering on shore or for launching in detachable bottom-trough of said house which may be used as floating or ground house. Descent submersible vehicle has platform with detachable wheels mounted over edges on side of floats which form trailer together with platform for ground transportation of house. Platform consists of longitudinal extended members interconnected by means of transversal pipes and/or rods (at varying number) for obtaining required ballasting before submergence of vehicle. Seats with transparent hoods are located along lateral sides of platform; their lower edges are located in area of passenger waist.

Proposed boat-hydrocycle has hull, reversible steering gear and motion control unit connected with engine and with reversible steering gear; driver and passenger seats are located on either side from CL at level close to WL. Boat-hydrocycle control unit is located between seats and is made in form of joy stick kinematically connected with rudder and with control system kinematically coupling the engine and reversible gear control. Control system is made in such form that when joy stick is inclined to "forward" from neutral position, reversible gear is shifted to "ahead running" position and engine revolutions increase in proportion to shift of joy stick and when joy stick is inclined to "sternward" from neutral position, reversible gear is shifted to "astern running" position and revolutions of engine increase also in proportion to shift of joy stick; joy stick is so connected with rudder that when it is inclined to one side, boat-hydrocycle turns to the same side and vice versa.

Proposed ship has passenger seat 3 in fore section 2 which is made integral with ship's hull and is provided with hand-rests 5 and foot-rests 6, as well as water-and-air discharge passage 12 for drainage of outside water. Passage 12 is connected with ship's bottom forming transversal planing step 11. Seat is located in front of screw-rudder without reducing the viewing angle for driver. Seat ensures reclined position of passenger. Centering of ship is effected due to sternward shift of driver's seat and/or storage battery and/or fuel tank and/or luggage.

Hull of proposed floating vehicle is made in form of rigid envelope of surface of revolution where person may be embarked. Motion unit makes the floating vehicle move on water surface. Motion unit includes starter made separately from floating vehicle and used for sending pulse for initial motion; starter is located on surface of water basin or in immediate proximity. Starter is made in form of tube.

Proposed water bike has floating body and load-bearing members made in form of front hydrofoil connected with rudder secured on body and rear hydrofoil. Water bike is additionally provided with bladed propulsor made in form of monoflipper mounted behind rear hydrofoil and articulated with it by its leading edge for relative turn. Water bike is also provided with pedal drive including right-hand and left-hand levers mounted on common axle; these levers are articulated with rods connected in their turn with bladed propulsor; rear hydrofoil is immovably secured relative to body.

Invention relates to collapsible floating docks of adjoining water area and coastal structures. The proposed dock features a cellular design and consists of the hexagonal floating modules made from a composite material, consisting of polyurethane enclosure and compacted foamed plastic fitted there inside. Detachable fasteners represent horizontally located plates jointed by vertical rods. Aforesaid plates feature teeth bent towards the module and conic recesses made at the plate centre to receive the rod heads. A part of floating modules features recesses for mooring floating means. Note that the dock is equipped with detachable hand-rails with fasteners.

Proposed flowing house has above-water and underwater parts. Underwater part represents a cylindrical base accommodating the house draft stabilising and adjusting tanks, and fluid fuel storage tanks. Aforesaid cylindrical base changes over into a funnel part terminating into wedge-shaped part. There are channels intended for mooring and/or immobile storage of minor floating vessels arranged at the level of actual water-line oscillation.

Proposed device comprises housing with working medium circulation channel and working medium blower arranged therein. Suction and discharge holes of aforesaid channel are arranged opposite each other on housing convex surface to allow working medium to flow around it. Aforesaid channel consists of straightening parts arranged behind suction end ahead of discharge end that feature rectangular cross section and pass into those parts which are located ahead and behind of blower, respectively. Said straightening parts feature annular cross sections.

Invention relates to water transport and can be used in constructing motor sailers. Proposed motor sailer has 24-to-36 m-long hull with inner compartments, at least one screw propeller, at least one fuel tank, at least one drinking water tank, distilling plant, at least one mast with sails, appliance to facilitate unsinkability made from impermeable closed-porosity material that fills inner chambers of the hull, storage batteries and refrigerators to store foodstuffs. Volume of fuel tank or total volume of fuel tanks makes at least 8 m³. Drinking tank volume makes at least 6 m³. Volume of refrigerator chambers makes at least 4 m³. There are hold and compartments inside sailer hull for car, motor boat, fishing and diving equipment. Sailer is furnished with inflatable pontoons secured to the hull and storage batteries.

Proposed ski consists of float located on tube with solid skeleton having grates at front and rear to which valves in form of strips, gills and scales are secured for admitting water during forward motion of ski and closing water volume in tube during backward motion of ski; ski sticks have handle at one end and smaller ski at other end.

Proposed device includes float base, pedals and blades which are rigidly secured in pairs at angle of 90° and are articulated on longitudinal axle of float base for performance of reciprocation and rotary oscillations and for emergence at horizontal position. Blades have symmetrically streamlined profile and are provided with brackets on which pedals are articulated.
