The invention relates to the field of water transport, in particular for the transportation of cars, other vehicles and passengers between the banks of lowland rivers and lakes.

Famous ferry high promotomobile for rail wagons and other wheeled vehicles containing mover with propellers located on both sides of the Central longitudinal axis of the ferry (see the description of the invention to the author's certificate of the USSR No. 439439, CL. WV 35/54, publication 15.08.1974, bull. No. 30).

Known steam cannot be used for lowland rivers, non-navigable due to shallow water in the dry season, and for lakes coastal shallow waters and water vegetation.

Known vapor containing "pontoon ramps placed on it troublefree device and the rollers for engagement with the rope stretched across the river, made with add-ons for the crew and passengers, are placed respectively on the sides of the pontoon with the formation between them along the median plane of the pontoon cargo area..." (see the formula of the invention according to patent RU NO. 2051511, 6 WV 35/54 declared 25.03.1994).

The disadvantage of this ferry is the following.

Known steam cannot be used on navigable rivers, which run, in addition to boats and motor boats, ships with towering on the water deck. On many rivers convenient for mooring along the coast is not located on the opposite sides in a straight line (across the river), and steam with a rope across the river does not solve the problem of crossing.

Objective of the claimed invention is the reduction of the material of the ferry, providing a relatively high provatopoulos with a small draught, allowing to overcome areas of the water body (river, lake) is a small, relatively, depth. This propulsion ferry must provide high reliability with the passage of parts of the water with aquatic vegetation and to ensure the maneuverability of the ferry when running across and along the twisting river, skirting the shoals and other obstacles on the course of movement.

The invention consists in the following.

Ferry river, containing a pair of spaced across the width of the cylindrical pontoons mounted between the pontoons cargo deck for vehicles, crew and passengers, while the upper surface of the deck is located approximately in the median plane of the cylindrical pontoons, and in the operation of its lower part immersed in water, while providing a positive buoyancy of the deck, and mounted on the ferry propulsion installation.

Unlike these counterparts, to reduce material consumption, Gruzovaya made in the form of upper Board flooring connected to the lower, submerged part, which is designed as a sealed semi-cylindrical shells, placed parallel to the longitudinal axis of the ferry.

Thus the cavity between the membrane and the bottom Board bottom deck filled with light vodonepronimaemye material, and the semi-cylindrical shell and the side cylindrical pontoons made of synthetic material, similar in composition and strength parameters with firm wood-fiber plate. (This ensures a sufficiently high positive buoyancy of the cargo deck together with pontoons and small sediment ferry at the highest load.)

The ferry is equipped with a propulsion device, made in the form mounted on the sides of the cargo deck two nodes, each of which is made in the form of a pipe, and engine propeller propeller placed inside a pipeline and coupled to a pipeline of the steering nozzle, which is mounted to rotate in an approximately horizontal plane with respect to the pipeline without affecting the throughput. To ensure synchronous rotation of both of the pipes they are pivotally connected by a rod between them, and on one of the pipelines is mounted a lever articulated truss node with a drive mechanism to rotate the tail pipes.
