The question of the exact weight of the hull is one of the most critical when choosing a swimming vehicle, especially when it comes to the legendary Kazanka series. boat This is a crucial factor in making a purchase decision, as it is a parameter that directly affects the possibility of transporting a passenger car on the roof and the ease of launching alone. If you are wondering how much a Kazanka boat weighs without boules, the answer requires specific modifications, since the Kazan Motors and Production Association plant produced different versions with significant differences in design.
In this article, we will discuss in detail the technical specifications of the most popular models, such as: Kazanka-M and Kazanka- 2MThe first is a design that was designed without external inflatable or metal boules, and understanding the actual mass of the body is not only necessary for logistics, but also for proper selection. outboardTo avoid transom overload and ensure safe and stable running speed on the water.
It is important to note that the figures stated in data-sheet figures often refer to the “dry” weight, which can differ significantly from the real weight of the ready-to-use product with attachments. The real weight of the Kazanka body without boules can vary from 135 to 155 kg depending on the year of production and the thickness of the duraluminium alloy. Below we will analyze in detail what this mass consists of and how it affects the performance of the vessel.
Features of the design and materials of the body
The main material for the production of boats series "Kazanka" became aviation duraluminium, which predetermined their weight specifications. polymeric-composite materials Dural is very strong, but has its own specific density. Boolean models, such as the classic Kazanka-M, were assembled by riveting, which added stiffness, but also influenced the final weight by using a large number of fasteners and reinforcing profiles.
The thickness of the skin sheets varies depending on the loading of the nodes: the bottom was usually made of a thicker sheet than the side, which ensured resistance to impacts on the water surface and obstacles. The absence of boules in early versions allowed to reduce the overall weight, but this imposed serious restrictions on the stability of the vessel. lightness It also provided safety, which eventually led to heavier versions with velocity boules that became the standard for later models.
It's worth noting that duraluminium is prone to corrosion when it comes into contact with copper and some other metals in salt water, so owners of these boats had to pay special attention to care. The weight of the design also depended on the quality of the metal rolling over the years, which can lead to small discrepancies in data-sheet figures and reality. However, engineering at the time allowed to create a fairly light and durable frame that can withstand significant loads.
⚠️ Warning: When buying a used boat, be sure to check the condition of rivets and welds, as metal fatigue can be imperceptible externally, but critical for safety.
Technical specifications of the Kazanka-M model
Model Kazanka-M It was designed as a lightweight and affordable alternative to heavier boats designed for use with engines up to 12 hp (in later versions up to 15 hp), and the lack of boulders is a key feature of this model, which significantly influenced its weight and behavior on the water.
Dry weight of the hull Kazanki-M This figure allows the boat to be transported in the upper trunk of a passenger car, although the loading and unloading process requires physical training or the participation of two people. The design of the hull of the "monodrome" type with keeliness in the bow ensured satisfactory seaworthiness in calm water, but the lack of lateral support made the vessel sensitive to displacement. centre passengers.
The boat's dimensions also played a role in shaping its mass. At 4 meters long and 1.6 meters wide, the hull had enough space to accommodate four people, but the buoyancy margin was limited. This meant that overloading the boat was unacceptable, as it could lead to a rapid descent and the entry of off-board water into the cockpit.
☑️ Checking the condition of the boat before buying
Weight comparison: Kazanka-M and Kazanka-2M
In order to better understand how much the Kazanka boat weighs without boules, you need to conduct a comparative analysis with the model. Kazanka- 2MThis modification was designed for more powerful engines and had a reinforced design, which inevitably affected its mass. If the standard Kazanka is focused on quiet fishing, the two was created for more dynamic use and plane with greater load.
Body weight Kazan-2M The difference is between 150 and 155 kg, about 15 kg more than its predecessor, due to the use of thicker metal in the power elements of the set and the increased dimensions. The increased length (4.5 meters) and width (1.6 meters) required a more serious frame to keep the stiffness in the excitement. Despite the lack of boules in the basic concept, some versions could be equipped with removable elements, but the classic weight is indicated for a clean body.
The weight difference is particularly noticeable in operation, and while 138 kg can still be rolled by hand if you have skill, 155 kg is already a serious load, requiring the use of a winch or the help of a partner. engineFor many anglers, this is a crucial argument in favor of a heavier model.
| Parameter | Kazanka-M | Kazanka- 2M | Kazanka-5 (with boules) |
|---|---|---|---|
| Body weight (kg) | 138 | 155 | 190 |
| Length (m) | 4.0 | 4.5 | 4.58 |
| Width (m) | 1.6 | 1.6 | 1.6 |
| Load capacity (kg) | 400 | 400 | 400 |
Effect of weight on speed
A heavier body requires more engine power to get on plane. A difference of 20 kg may require a power increase of 5-10 hp to achieve similar speed specifications.>
Impact of the absence of boules on operation
The absence of side boules is not just a matter of aesthetics or material economy, it is a fundamental characteristic that affects the quality of the body. stability Boole-free Kazanka boats have narrow waterlines and high sides, which, when rolled, poses a risk of a sharp overturn, which is why the weight of the empty hull is a secondary factor in this case compared to the weight distribution of the crew and cargo.
When operating a boat without boulders, it is critical to follow the rules of boarding: passengers must be symmetrically positioned relative to the diametrical plane, and any sudden movements can lead to a dangerous roll. Unlike models with boulders, which forgive errors in management and allow you to stand up fully even in a parking lot, Kazanka-M requires the driver and passengers to discipline and understand the physics of swimming.
However, the lack of boules has its advantages: the boat becomes already in size, which makes it easier to tow and store it in the garage. In addition, the lack of additional air tanks on the sides reduces sailing and water resistance, which theoretically can positively affect speed with low-power engines. However, on excitement, the lack of boules makes the course harder and roller.
⚠️ Note: Operation of boats without boules is prohibited in wind and excitement above 2 points, as the risk of overturning becomes critical.
Transport and storage of the boat
The weight of the boat Kazanka without boules, which is about 140-150 kg, dictates its terms of transportation. For transportation on the roof of the car (Volga, Moskvich or modern crossovers), one person will not be enough for a safe load. It is recommended to use special guides or the help of a second person, so as not to damage the paint coating of the car and not to tear off the back.
The duraluminum hull requires certain conditions when stored. Although it doesn't rust like steel, it's susceptible to electrochemical corrosion and oxidation. It's best to keep the boat upside down on soft supports to avoid deforming the bottom under its own weight, especially in hot weather when the metal becomes more plastic. Regular washing and drying of the cockpit are also mandatory.
To facilitate the process of launching, many owners make special trailer trolleys. Given the weight of the hull, the trolley must be reliable and have a good margin of safety. Using a winch on a trailer allows one person to easily cope with the boat, making the process of leaving the reservoir comfortable and safe, regardless of how much the Kazanka boat weighs without boules in a particular instance.
Comparison with modern analogues
Comparing the weight of Soviet duraluminium boats to modern fiberglass or aluminum-magnesium alloys, one can see a significant difference: modern technology allows you to create hulls of the same size weighing 80-100 kg, which greatly facilitates operation. However, Kazanka wins in maintainability: dural can be ruled with a hammer and patched, while the composite requires complex repair technology.
Many owners are thinking about upgrading their lighter hulls, and the Kazanku-M is a popular tuning that increases overall weight and changes the center of gravity, and after this upgrade, the boat may require a more powerful motor to maintain driving performance, which brings us back to the issue of weight and power balance.
So the choice between a classic Kazanka without boules and a modern anal depends on the owner's priorities. If you care about historical accuracy, the possibility of self-repairing and the availability of spare parts, a 140 kg weight is an acceptable price for these benefits. If the priority is maximum lightness and safety, it is worth considering more modern options.
The classic Kazanka without boules is a compromise between minimal weight and simplicity of design, requiring the owner to be highly disciplined on the water.
Frequently Asked Questions (FAQ)
Can I install a 25 hp engine on Kazanka-M?
Technically, it's possible, but it's extremely dangerous. A boat without boules has low stability, and a powerful engine can cause a sharp roll or even roll over when maneuvering, the recommended power for this model is up to 12-15 hp.
How to reduce the weight of a boat for transportation?
You can't reduce the weight of the body without breaking the integrity of the structure, you can remove all the removable equipment: seats, handucts, paioles, and you also need to clean the case of accumulated dirt, algae and excess cargo in the holds.
How safe is Kazanka without boules on a large pond?
Safety depends on weather conditions. On calm water (lake, river without flow), the boat is safe if landing rules are followed. On large bodies of water with the possibility of a sudden wave (Ladoga, Onega, large reservoirs), operation without boules is not recommended due to the high risk of overturning.
Does the weight of the boat affect fuel consumption?
Yes, it does. A heavier body requires more power to accelerate and plane, but the difference between 138 kg and 155 kg is not critical for fuel consumption, it's more important here aerodynamics, propeller condition and boat loading.
