The first serial production of Soviet Amur boats, the characteristics of which we will consider below, was launched in 1970 in a small batch of 400 copies. The manufacture of swimming equipment was established in Komsomolsk-on-Amur. The main purpose of the vessel is operation in freshwater bodies of water and rivers. The working permitted wave height is not more than 1.2 meters, stormy waves - up to four points. In the future, the modification was finalized, several versions appeared, including the option for the sea.
Design features
According to the general characteristics of the Amur boat, its hull consists of duralumin in the initial versions and AMg alloy in the later versions.
Design Features:
- Most joints are made using riveting, some seams are welded.
- Several bulkheads are responsible for the unsinkability and tightness of the compartments.
- An open cockpit is provided, which can be closed with a folding awning if necessary. It is stretched using a tube frame inserted into special connectors on the deck. The Amur-2 modification is equipped with a shelter-shelter.
- The passenger capacity is five people.
- Parameters in length - 5500 mm.
The forepeak of the vessel is hermetically sealed; access to this element will require the use of a hatch provided on the deck with tight locks. The cockpit is equipped with two rows of seats with a reinforced structure and soft upholstery.
Equipment
Given the characteristics of the Amur boat, the driver’s seat is equipped according to the standard scheme. There is a steering wheel and special devices for remote control of the power unit. There is also a shield with different devices that serve to control the operation of the main nodes. Under the cover of the engine compartment there is a space with a pallet for storing tools and small items of equipment.
In the aft part there is a motor chamber, under the passenger seats there is a gearbox transmitting rotations of an angular configuration. The following elements are located in the same compartment:
- Battery that powers the starter and the side lights.
- Cooling tanks for oil and working fluid.
- Capacity with water.
- Power unit cooling system block.
The compartment is closed by two covers that swing back to the sides. The boat as standard is controlled by an aluminum propeller with a diameter of 275 millimeters and a pitch of 312 mm. The vessel can be operated for oars. Fixing of elements is carried out by means of special fasteners on the sides.
disadvantages
Judging by customer reviews and the characteristics of the Amur boat, it has a number of significant drawbacks. Among them:
- Exposure when gliding tangible impacts, including with small waves of water. Such behavior contributes to the appearance of discomfort and some anxiety among passengers. Often waves lead to weakening rivets. Parts must be secured in a timely manner, otherwise a leak may appear.
- It is recommended to change the contours and increase the pitching of the boat, especially in the bow. Doing this procedure with your own hands is quite problematic. The best option to reduce the impact of the shock wave is to strengthen the bottom or purchase a modernized analogue.
- The exit of motor conversion beyond the established standards.
- The cooling unit has one circuit that does not adequately cope with maintaining the normal operating temperature of the vessel. Such a problem is fraught with the formation of corrosion processes on the metal parts of the motor. In this regard, owners often carry out tuning of the Amur boat in terms of the cooling system.
- The design of the ship does not provide for a reverse stroke.
- To isolate the transmission torque of the shaft and the “engine”, an automobile clutch is used, not designed for a long stay in an inactive state. The presence of such a node contributes to additional complexity in the management and discomfort of the driver.
Benefits
Judging by the reviews, the characteristics of the Amur boat have a number of positive qualities, namely:
- Pretty modern and thoughtful exterior.
- Well-planned “architecture” and design of the boat with smooth contours.
- Good roominess in terms of luggage.
- Reliable operation of the remote control drive.
- Competent development of a protective tent.
- High speed (40 km / h).
Amur boat: technical specifications
The fuel consumption of the water jet of the vessel in question depends on the loading of the craft. It is worth noting that the engine from the Moskcichich-412 car acts as a power plant. Other boat parameters:
- Length / width / height - 5500/1870/820 mm.
- The overall rainfall is 270 mm.
- The weight of the vessel with full equipment without passengers is 630 kg.
- Capacity - five people.
- The payload parameter is 500 kg.
- Engine Features - uses AI-92 fuel.
- Power working - 60 l. with.
- Type of connection - rivets and welding.
- Speed threshold with a load of 40 km / h.
Electric arc spot welding is used to equip deck and bottom stringers. The thickness of the casing in the bottom area is up to 2.5 millimeters, in areas of reduced load - 1.5 mm. The basis of the transverse set consists of ten frames. For an overnight stay, a folding sofa and front seats are provided. Luggage racks for storing a trench tool are provided along both sides. Fuel is refueled in two identical tanks, the volume of each of which is 50 liters.
Cooling
The engine of the Amur boat has a single or dual circuit cooling system. In the second case, a retractor pump is used, the water after the intake is directed along two vectors. One stream goes to the reversing reducer (for temperature control), then to the exhaust pipe. The second direction enters the manifold jacket, the radiator, providing a thermal reduction in oil parameters. After that, the liquid is delivered to the refrigerator, where heat is exchanged with the refrigerant from the internal circuit. At the finish, mining is dumped overboard.
Technical characteristics of the Amur-2 boat
Below are the main parameters of the specified modification of the vessel:
- Overall dimensions - 5620/1830/930 mm.
- Structural settlement - 232 mm.
- Kilovost - 18 degrees.
- Capacity - 5 people.
- The carrying capacity is 500 kg.
- Speed at full speed - 47 km / h.
- The power plant is a gasoline engine from Moskvich-412.
- Power - 60 "horses".
- Type of connection - rivets.
Comfort
The interior of the cabin is equipped with a pair of soft seats, which, when laid out, form three berths. Access to lockers is also freed, a transformable table is provided in the middle. Cutting length - 1800 mm, height - 1150 mm.
The stability of the vessel is ensured by a set of foam blocks mounted on a hull made of an alloy of aluminum and magnesium. Due to its increased resistance to corrosive processes, the swimming means can be operated in salt water. removable awning protects the cargo from the weather, and it is mounted according to the standard principle that is characteristic for this line of swimming devices.
Amur-M
The main purpose of the specified water vehicle is recreational and tourist trips along fresh water bodies and rivers. The maximum distance from the coastal zone is up to five thousand meters, with a wave height of up to 75 centimeters. Compared with the first modification, the boat received different contours, a moderate keeled index in the transom and near the cheek bones of the stem.
Characteristics of the Amur-M boat:
- Dimensions along the length / width / height - 5500/1870/820 mm.
- Draft - 270 mm.
- The weight of the vessel without passengers in the equipped state is 630 kg.
- The carrying capacity is 500 kg.
- Capacity - five passengers.
- Engine type - automobile engine "Moskvich-412", with a capacity of 60 horsepower.
- Speed - 40 km / h.
- Connection - riveted-welding type.
Amur 3 Version
This option is an analogue of the 2nd series. The only difference is the increase in the size of the cockpit due to the dismantling of the cabin. This point also affected the decline in ship value. Other characteristics of the Amur-3 boat are identical to their predecessor. The exit on such a ship is allowed at a distance of up to three thousand meters from the coast, with a wave height of not more than 1200 mm.
To improve seaworthy parameters, the Amur-2M and Amur-3 modifications are equipped with sharper contours and have an increased rate of deadlift of frames. The cheekbone is slightly elevated in the stem part. Such a solution made it possible to reduce the impact of shock waves and level the excessive sprayability of the cockpit. Reduced pitching in the stern area allowed to improve hydrodynamic performance with ease of transition to planing mode.
Modification "Amur-D"
The specified tourist variation differs from the “M” version by the presence of a propulsion and steering device in the form of a Z-shaped drive with a reclining column. The body part is made of duralumin by riveting and welding.
Other characteristics of the Amur-D boat:
- The thickness of the bottom sheathing is 2.5 mm.
- The same indicator for deck and side decking is 1.5 mm.
- Hull elements - forepeak, engine compartment, cockpit.
- Cross set - ten frames.
- Seats - two, with the possibility of folding into berths.
- Fuel tanks - a pair of tanks with a total capacity of 100 liters.
- Speed - 40 km / h.
- Dimensions - 5500/1870/820 mm.
- Mass - 0.63 t.
The vessel’s cockpit is closed by a folding awning, which, when disassembled, is placed in the rear of the compartment.
Power point
The engine of the Amur boat of the D series is a convertible version of the 412DE motor and a tilt-and-turn column (POC). The unit is mounted on three soft supports, connected to the POK using a driveshaft.
Power plant parameters:
- The engine type is a four-stroke four-cylinder carburetor engine.
- Power - 60 liters. with.
- Average fuel consumption - 225 g / l s. h
- The fuel used is AI-93.
- Speed - 4500 rotations per minute.
- Additional equipment - liquid and oil coolers, improved exhaust manifold, updated lubrication system.
During the cooling process, the seawater enters the external circuit using a self-priming pump. At the output, the flow is divided: one direction is a reverse gear, the second stream is the space behind the exhaust manifold jacket. The heat exchange process of the liquid of the internal circuit and the incoming water is carried out in the refrigerator (it is made integral with the expansion tank). Next, the mixture through the stop valve goes overboard.
What do the owners say?
Reviews about the boat Amur are contradictory. This is especially true for the first versions. The disadvantages of consumers include poor resistance to the wave, the lack of reverse motion, unreliable operation of the clutch and the cooling system. Users note that subsequent modifications are devoid of these shortcomings, have an optimal combination of cost and quality. Most owners point to a good capacity of the vessel, comfortable seats, a well-thought-out cockpit design with the possibility of fencing with an awning, as well as a beautiful exterior design of the boat.
