The choice of a swimming aid always begins with an assessment of its technical specifications, and for Soviet classics, such as: KazankaAnd weight is one of the determining factors, and it's a parameter that directly affects not only how you take the boat to the water, but also what kind of engine you can get it to the plane. Many beginners underestimate the impact of hull mass on performance, focusing only on length or width, which often leads to errors in the configuration of the boat complex.
The empty body mass is the base from which to calculate the buoyancy and stability margin. Depending on the year of release and the specific modification, the numbers can vary significantly, which is important to consider when buying a used version or planning an upgrade. Understanding the real weight allows you to correctly choose the transax motor and avoid overload problems that can be dangerous on the water.
In this article, we will analyze in detail the weight specifications of various modifications of the legendary aluminum-boatThe impact of mass on driving performance and how to legally reduce weight without losing strength, and you'll learn why some models are heavier than others and how this affects fuel consumption.
Factors affecting the mass of the body
The main material for the production of boats of the family Kazanka They were aviation aluminum and duraluminum, and these alloys are very durable, but their density and sheet thickness directly determine the final weight of the product. In Soviet times, they didn't skimp on metal, so older models are often heavier than their more modern counterparts or Chinese replicas, where the skin thickness can be reduced.
The hull design also makes adjustments. The deck, rundooks, cans and reinforced forespeak add kilograms to the total weight. For example, models with closed cockpits and full decks will always be heavier than open motorcycles of similar length. In addition, the weight can vary depending on the configuration: the presence of built-in fuel tanks, windshield mounts and fun switches also add up.
Corrosion and fouling Another factor that should not be ignored when evaluating the weight of a used boat, although aluminum does not rust in the same way that steel, oxidation and the accumulation of dirt, silt and algae in hard-to-reach places can add tangible kilograms. Regular washing and maintenance help keep the weight within factory values.
When buying a used boat, be sure to weigh it on the car scale along with the trailer to find out the real weight, since factory data may differ from the actual ones due to repairs and improvements.
Overview of the weight of popular modifications of Kazanka
Family Kazan There are many modifications, each designed for a specific purpose, and the mass range is quite large, from lightweight two-seater models to heavy five-seater catamarans, and understanding these differences is critical to choosing the right traction motor.
The first Kazanka The 460, which was built in 1955, had a body weight of about 130 kg, and it was a lightweight and fairly simple design that allowed the use of low-power engines of the time. Kazanka-M and Kazan 5They are heavier due to increased size and reinforcement of the structure for increased safety.
The mansion stands Kazankah-5M These are full-fledged motobots with increased payload capacity, and their weight in running order (without motor and equipment) can reach 200-230 kg, which requires more powerful equipment for transportation and towing.
specifications comparison table
For ease of analysis, we will summarize the data on the main models. The figures may vary slightly depending on the year of production and the specific manufacturer (Gorbunov Kapo, GAZ and others).
| Model boat | Body weight (kg) | Load capacity (kg) | Passenger capacity |
|---|---|---|---|
| Kazanka (D. 460) | 130 | 400 | 4 people. |
| Kazanka-M | 138 | 400 | 4 people. |
| Kazan 5 | 150 | 400 | 4 people. |
| Kazankah-5M | 190 | 500 | 5 people. |
| Kazanka- 2M | 250 | 800 | 6 people. |
As you can see from the table, the transition from the model Kazan 5 ce Kazankah-5M This led to an increase in weight by almost 40 kg, but at the same time increased the carrying capacity. Kazanka- 2MThe, being the largest and most comfortable, has an impressive weight of a quarter of a ton, which makes it unsuitable for use with weak engines up to 10 hp.
The influence of weight on driving performance and planing
Boat weight is the main enemy of planing when using low-power engines. The heavier the hull, the more energy it takes to pull it off the water and put it into sliding mode. Kazan 5M With a full crew, a 9.9 hp engine may be at its limit, especially if the screw is picked up incorrectly.
When the boat is overloaded, it starts to dig water, increasing its resistance and fuel consumption, and the engine runs at higher speeds, but the speed does not increase. manageability And it falls, and the boat becomes more susceptible to side wind and wave. Kazanka-MThey are much more willing to go plane and require less power to maintain cruising speed.
⚠️ Attention: Exceeding the permissible load capacity or installing an engine that is too powerful on a lightweight hull can lead to loss of stability and rollover. Always balance the weight of the boat, passengers and engine power.
Transportation and storage: weight nuances
The issue of transportation on a trailer is especially acute for owners of cars with limited capacity. Kazanku-M can be four relatively easy to re-canned and loaded on the roof or in the back of the pickup truck, then with the help of Kazankoy-5M or 2M Their weight requires the use of a trailer and, preferably, a winch for loading.
When stored on land, weight also plays a role. Heavy boats are harder to pull ashore for drying after each fishing trip. Often owners of heavy modifications leave them on the water or use stationary slips, because each time dragging 200+ kg of metal by hand is a laborious task.
☑️ Preparation for the transport of the boat
Weight loss and modernization
Some owners go to drastic measures to try to lighten their boats, cutting floorboards, removing hazelnuts or replacing heavy wooden cans with lightweight aluminum profiles is common practice, but it is important not to overdo it or violate it. strength-plate hull.
Replacing a standard anchor box or fuel tank with lighter plastic can save a few kilograms. It is also worth paying attention to the equipment: modern lithium batteries weigh several times less than lead, which significantly changes the weight and overall weight of the boat.
Can I cut the sides of Kazanka to reduce weight?
In theory, it is possible to remove some of the metal, but it is strictly forbidden by registration rules and is life-threatening. Aluminum alloy after welding or cutting at home loses strength in the seam zone, which can lead to the collapse of the body on the wave.
⚠️ Attention: Any changes to the design of the boat, affecting its stability and buoyancy, must be agreed with the authorities of the GIMS. Unauthorized alteration can lead to a ban on operation.
Frequent Questions About Weight of Kazanka
How much does Kazanka-5M weigh with an engine?
The weight of the boat Kazankah-5M The weight of the motor depends on the model: Yamaha 9.9 It weighs about 36 kg. Tohatsu 18 The total weight of the kit will be the sum of these values plus the weight of fuel, oil and equipment.
Why is Kazanka-M lighter than Kazanka-5?
Kazanka-M It has a simpler design without a developed forespeak and deck, as well as smaller dimensions. Kazan 5 It was created as a more seaworthy and comfortable model, which required strengthening the body and adding elements that increased the weight.
What kind of engine is needed for heavy Kazanka-2M?
For confident planing Kazan-2M (weighing 250 kg) with a crew it is recommended to use engines with a capacity of 25-30 hp and above. Motors up to 15 hp will be able to bring the boat to plane with only one person on board.
The weight of a boat is not just a number in the passport, but a fundamental parameter that determines the choice of engine, method of transportation and safety of navigation.
To summarize, we can say that the choice between light and heavy modifications. Kazan If you have a powerful car and a big trailer, and you like to fish with a big company in spacious reservoirs, it's a heavy job. 5mm or 2M For small lakes, frequent trunk transport and fishing, the two of you are better off with light. Kazanka-M or Kazan 5.
