The boat, trailer, floating boat "Don" was produced on Gorky aircraft factory(now OAO NAZ Sokol) since 1978. "Don" is a multifunctional device, the main purpose of which is the organization of recreation by the water and on the water. The boat-transformer can be used both as a cargo trailer, and as a house for temporary living in nature and as a motor vessel. At the same time, both the entire hull and its bow can be used as a boat.

Frame

Structurally, the "Don" consists of two sections, having a hinged mount in the upper part. The body is made of duralumin. The transverse set is made with frames, there is no longitudinal set, and the rigidity is provided by the redans and stiffeners molded in the sides. Connections of body elements are made with rivets.

Boat 5 meters long

You can use the Don as a full-size boat by rigidly connecting both sections. The catamaran bow contours are smoothed out by a hydraulic shield for a smooth transition to a flat-bottomed aft section. In this version of the boat, you can install remote steering, which somewhat hides the usable area when operating the Don as a tent.


The transom of the boat allows you to install an outboard motor with a power of up to 30 hp on it. The speed of the boat in this case can reach 37 km / h. Despite the significant stability of the boat on the stand, its seaworthiness is far from ideal. The navigation area is limited by the manufacturer to inland water bodies with a wave height of up to 0.3 meters and a distance of up to 1 km from the coast.

Boat 3 meters long

The front section of the Don boat can be used separately. In this variant, the dimensions of the boat are also not optimal, and to reduce the effect of dolphinization of an almost square vessel, trim plates with buoyancy cavities are used. In this form, the boat is capable of gliding at speeds up to 42 km / h and even pulling a skier with the same maximum 30-horsepower engine.

floating dacha

Both sections of the Don are about 2.5 meters long, which makes it quite convenient to stay in it for the night. For this, instrumental seats are provided. Included in the Don offered a two-section awning, separate for the front and rear. The awning is installed on the aluminum ribs of the skeleton, which rises almost a meter and a half above the side. If the resting company is small, you can take as a tent aft and leave it dry. Use the bow section on the water.


The total area of ​​the assembled sections of the floating house is 8.5 square meters and can accommodate up to 6 people for the night. The hydraulic shield fixed on the bottom can be used as a table.

Trailer

The aft section of the Don serves as the body of the trailer. Wheels with suspension with spring-hydraulic shock absorbers are fixed on it. The drawbar is removable and is attached directly to the hull of the trailer boat. Many owners upgrade their trailer suspension to increase its reliability. When transporting the boat, bow stacked on top of the stern. The space between the bow trim and the bulkhead of the aft area is closed by the same hydraulic shield. The nose section weighs over 70 kg. A minimum of two people are required to dismantle the boat.

Conclusion

The trailer boat-floating boat "Don" was sold at a price of 2300 rubles and was produced in relatively small quantities. Currently, the popularity of this model does not subside and the cost of such a transformer in the secondary market, depending on the condition, reaches 150 thousand rubles *

To have a small cabin boat - a self-propelled floating cottage - is the dream of many. The parking place of such a summer residence can be changed; We have many rivers and lakes, and the banks of most of them are very beautiful. The appeal of life on the water is undeniable.

What requirements should a self-propelled dacha of minimum size meet?

It should have sleeping places, a place for cooking, a table with seats around it, an open area - to bask in the sun or dry off after bathing; it is desirable to have a latrine. Finally, the boat-dacha should be inexpensive and be accessible to everyone. The minimum boat-dacha is calculated for two people, but for the most part it is necessary to provide two more places for children.

In the stern of such a vessel there is a sleeping cabin, in which two folding beds made of aluminum tubes are placed along the sides. A narrow table is installed under the aft window in the cabin, which at the same time stiffens the aft bulkhead. The table in the middle part can be made sliding. On the opposite wall of the cabin there is a sliding door and a clothes hanger. Curtains can be hung on the windows, and shelves for books can be installed between the windows.

In the bow there is a salon (it is also a wheelhouse, a dining room, a living room, etc.). In the middle of the cabin there is a table, on the left - a helmsman's place with a steering wheel and engine control levers. The table, as in the sleeping cabin, can be sliding. The salon can also accommodate two beds for children - (or for guests).

A galley is located between the sleeping cabin and the saloon on the port side. The galley has shelves for dishes and food. If you remove part of the kitchen table, then a tourist gas stove or a kerosene stove can be installed in the opening. On the right is a small sink; it serves for washing dishes, and on cold days when you can’t swim, for washing.

On the starboard side, between the sleeping cabin and the saloon, there is a toilet bowl with an open hole, without flushing. When swimming through the canal, it is replaced by a bucket.

For the convenience of mooring to the shore, a wide open area is located in the bow; it is convenient to go ashore or swim from it.

Outboard motors are offered as engines on the boat-cottage.

The desire to make boats as fast as possible led to the use of gliding contours. Tall superstructures require the use of a wide, stable hull. The way out was found in the use of a two-hull design, in which each of the hulls can be arbitrarily narrow. The use of two engines with a two-hull design is logical and convenient.

Description of the structure. The structural basis of a double-hull boat-dacha is a platform to which two floats are attached from below, and a cabin from above. The transverse rigidity of the platform, which has a thickness of 100 mm in the middle part and 200 in the bow, is provided by light beams placed every 300 mm, two internal bulkheads, as well as the front and rear walls of the cabin. Longitudinal rigidity of the platform is given by the sides of the floats and the longitudinal walls of the cabin.

Each of the two floats has two bulkheads or consists of three separate parts - bow, middle and stern. The parts of the floats are molded from hydrophobic fiberglass on polyester resins. The small width of the floats allows them to be made without frames; the strength of the floats is ensured by the end bulkheads and keelsons glued into the floats in finished form. The floats have a simple shape (except for the bottom of the bow) and small dimensions, which simplifies their manufacture.

It is also possible to manufacture floats from waterproof plywood. The contours of the bow in this case can be obtained by sticking a layer of foam on the plywood bottom, which is then processed according to the templates taken from the theoretical drawing and pasted over with a cloth. The bottom of the bow can also be glued out of veneer.

The aft part of each of the floats has a cut-out for the installation of an outboard engine shifted to the boat's midplane and a shielded box to protect the rest of the float cavity from being flooded with water. The transom of the aft part of the float is reinforced and adapted for mounting the engine on it.

The outer perimeter of the platform serves as a fender and is edged with a strip of durable material. To protect against water, the plywood sheathing of the platform is pasted over with a fabric on polyester resin.

Cabin walls up to the windows consist of plywood edged boards, middle part- from frames into which glass or plexiglass is inserted on rubber profiles. The roof is glued from fiberglass on a square lattice of foam profiles, edged at the bottom with strips of plywood. In case of difficulties with pasting, the roof can also be made of bent plywood sheets.

Sliding door cabins (two external, one in the latrine and one in the sleeping cabin) are installed on plastic skids.

The aft part of the cabin hangs over the transoms of the floats, in connection with which the upper parts of the outboard motors are inside the cabin and are not accessible from it. To reduce the penetration of smell into the cabin, the upper parts of the engines are enclosed in box casings protruding above the cabin floor.

The results of the speed calculations, based on the values ​​of the stop measured during tests of the "Moscow" engine, are presented in the form of a graph. As can be seen from this graph, when running under one engine "Moskva", with any displacement of a dacha boat, its speed will vary from 12 to 14 km / h. With two engines, the speed of the boat, depending on the displacement, increases to 27-35 km / h. In order for the total weight of the summer cottage to not exceed 720 kg (in this case, a speed of 35 km / h can be obtained), it must be built easily and without any frills. The approximate weight distribution (in kg) between the individual parts of the vessel is as follows.

Two floats .................................................. ...............144
Platform................................................. .................132
Cabin................................................. ......................136
Half Fuel Engines.......................................84
Camping equipment and personal belongings...................................74
Two passengers .................................................. ..............150
Total 720

If two more passengers are taken on board and the total weight rises to 870 kg, the speed will drop to 27 km / h, which is also, ultimately, not so bad.

The stability of a double-hull vessel, in which the maximum displacement of each float is more than three times the normal load falling on it, is certainly sufficient. On the move, due to the influence of dynamic forces, stability increases. The rolling of double-hulled ships occurs along with the waves, like a raft, since the own period of oscillation is very small.

If you wish, you can build an even smaller vessel with approximately the same characteristics, but for one Moskva outboard engine. Such a boat-cottage is built without a cabin, with one platform on which you can put up a tent. All sizes of floats according to the given theoretical drawing should be reduced by 1.26 times. The total length at the waterline will be 4000 mm instead of 5040, the full width of the floats will be 2330 instead of 2940 and so on.

The lower part of the graph shows the resistance of a vessel of such reduced dimensions for a displacement of 436 and 360 kg.

The project of this floating cottage based on a 9.5-meter jet boat with simplified contours, developed by Ya. Kobachevsky. He also built a solid hull with double diagonal planking of pine boards, lined on the outside with 3 mm sheets of AMg-3 alloy. finish building floating house happened to me. This task was complicated by the fact that after the death of the designer, all the sketches and diagrams he had made were lost.

To some extent, the ship is similar to the Beryozka, the project of which was published in the third issue of Boats and Yachts (1964), but, as it turned out, the hull was designed long before the release of the collection, but during the completion and equipment of the Yanta information from "KiYa" and all available materials were widely used.

An anchor chain 20 m long and two are stored in the forepeak. In the bow there is a "veranda" with two sofa-lockers on the sides, covered with a light duralumin awning of two halves connected on a piano hinge.

The superstructure has dimensions in terms of 5.0X3.0 m. Its walls and roof are made of bakelized plywood 10 mm thick; the roof is covered with epoxy resin. Wall height 1100 mm. Since the horizontal flooring (floor) is lowered below the deck (300 mm from the OL), the height of the rooms turned out to be 1800 mm. For thermal insulation, a layer of foam is laid along the walls and ceiling. The inner lining is made of mahogany decorative plywood and plastic with layouts along the beams. The side windows of the salon are made according to the type of trolleybus windows with sliding windows, the front viewing windows are made of plexiglass.

The aft cabin, separated from the salon by a sliding metal door, is equipped with built-in wardrobes for various purposes, hangers and shelves. There is also a kitchen table with shelves, a gas stove and a sink-sink, into which hot and cold water is supplied. Nearby is a combined bathroom - shower and latrine.

In the stern - in the engine compartment - a 45-horsepower Skoda 1201 automobile engine is installed with an additional casing on the exhaust manifold for heating water. Two gas tanks with a capacity of 80 liters are suspended below deck; canisters and an inflatable boat - a tuzik are also placed here. The deck of the Yanta is covered with corrugated rubber mats on glyptal varnish.

The driver's post is located on the port side in the bow saloon, near the front glass. Above the driver's head is a Plexiglas skylight.

For two years, in winter and summer, the whole family worked with great enthusiasm on the completion and equipment of the floating dacha. And then came the long-awaited moment of the first entry of "Yanta" into the voyage. What can be said in general about our vessel? This is a reliable and comfortable houseboat. Due to the high cabin, Yanta has a large windage, so the speed is directly dependent on the strength and direction of the wind and ranges from 15 to 20 km / h. Large weight causes significant inertia. It was also necessary to get used to the peculiarities of controlling the vessel due to the reaction of the jet of the water cannon.
