The invention relates to inflatable boats.

Known inflatable boats, see ed. St-in the USSR №608695, in particular catamarans. But the special distribution catamarans not received due to the large time of Assembly and disassembly, the difficulty of obtaining sufficient inhabited places on the dais, high centers of gravity and high consumption of frame materials.

The objective of the invention is to remedy these disadvantages.

The essence of the invention that the catamaran has an open top container for legs with hinged Windows that back in the direction of the lid, the container has a front, back sides and lid openings or ears for the transverse tubes of the frame, and the tubes are attached to the inflatable cylinders (the optimal number of pipes or three).

This container (like a square bucket) is in the upper part of rectangular cross-section, and below the holes or Ushkov, especially below the waterline, may have rounded corners. The upper edge of the container may be flush with the cylinder or slightly higher. Centered container: part of the pipe, for example, two of the three, has a guard to the left of the container, and the part on the right. Collected from the cylinders into a single whole, they clamp the container in the center.

Such single boats are used, as a rule, fishermen and only to depart at 100-200 meters from the shore and anchor, so kotoroe deterioration speed catamaran from the presence in the water is bad, streamlined container does not matter. The catamaran will still be faster boats.

The container may be made of fiberglass, good thermoplastic, such as polypropylene, or from duralumin, including welded.

But in any case the upper zone, where there are holes or ears and the hinges should be reinforced.

When sufficient strength of the container are no special measures to stiffen the catamaran is not required, otherwise you should consider two diagonal cord connecting the cylinders or tubes.

The container is a multifunctional element: in addition to the basic functions, it is during transportation of the boat plays the role of the bags, which formed the cylinders, pump, etc. on the banks or in public transport it is possible to sit, it can serve as a bucket of live fish, in particular even while staying on the water in warm weather or when the boots). And the metal container can serve even the pot.

When a sufficient size of the container can be placed and other things of the fisherman, both during transportation and afloat. The minimum dimensions of the container: length 32 cm, width 40 cm

On the lid of the container must be the grip belt to the carriage as the bags, and on the long side of the container may be mounting for transportation as a backpack.

On the reverse side of the cover has a plate slightly smaller than the sizes of, articulated (for example piano loop) attached to the cover and forming an open position past the back of the seat, which plate is held by two cords on each side, forming a sort of armrests. Cords can have a shell of porous rubber. Cover and backrest can be made from buchanani and may have a soft, warm and nanimokamo coating of polyethylene. For oars can be used the same pipe, as and for the frame.

Thus, the man sits almost in the chair is very comfortable and safe.

For security and to fold things in the lateral gaps between the container and the cylinders may be tensioned wire mesh or fabric from the first to the last tube of the frame (dressed on their sleeve).

The cylinders may have tapered ends (on the sketch on the left) or simplified ends "clamping" (on the sketch on the right), as the speed does not matter.

It is also possible sports variant of the catamaran, mostly for children, both rowing and sailing. He has a more elongated cylinders of smaller diameter with a very elongated tapered ends. Cylinders should be around 40-45%, in this case they have quite good reservoir quality. In rowing embodiment, the catamaran has a longitudinal Board width of about 60 cm (container is missing and what not comes down to the waterline) with skiers Bank and foot rests for.

In the sailing version of the catamaran has a cockpit in the form of a box, for example from buchanani or fiberglass, on the lower side of which there are ears to the pipe frame. The size of the box is approximately: length 60 cm, width 120 cm, and the side walls should be bent outward, as at landing the man across the movement (typical for sailing) these walls serve as a backrest. The center of gravity sailing catamaran should be shifted back to consider the point on the force of the sails. Nasal cones should lift up and feed lower down.

In both cases the use of a life jacket is mandatory.

Such a simple (two cylinder, three pipes, boards) and relatively inexpensive catamarans can be used in children's sports schools, camps, boarding houses.

In figure 1, figure 2 shows the catamaran on a scale of 1:15, consisting of two cylinders 1, three duralumin tubes 2 and the container 3, attached to the pipe using Ushkov 4. Open the lid of the container serves as the seat 5 and the hinged plate 6 held in position by cords 7, serves as a backrest.

This catamaran can be provided not swinging oars and oars type "Lasta", "Dutch" or "ULAW", or rowing screw with manual transmission.
