Soviet-made metal boats known as KazanThe duraluminium vessels have been a legend for more than half a century, but for a modern boating, the actual weight of a used or refurbished vehicle is a critical parameter when choosing a used or refurbished one.
The question of how much a boat Kazanka with boules weighs, has no single answer without specifying the specific modification and configuration: the difference in weight between the "dry" hull and a fully manned vessel can reach hundreds of kilograms. Accurate data They are necessary not only for transportation on a trailer, but also for calculating the load capacity and choosing the optimal power of the outboard motor.
In this article, we will discuss in detail the weight specifications of various modifications, the effect of boules on the total weight and design features that distinguish the Soviet dural from later versions.
⚠️ Note: The weight listed in the documents is often "dry" and does not take into account the weight of floorboards, cans, knives and attachments, which can be an unpleasant surprise when loading on a light trailer.
Design features and the effect of boules on the mass
Booles are sealed compartments that significantly increase the stability of the vessel, a response to numerous cases of early models tipping over when riding a wave or abruptly moving passengers, but the installation of booleans inevitably leads to an increase in the total weight of the hull.
The duraluminium from which these boats were made is of high strength, but requires a certain sheet thickness to ensure durability. Boolean design Not only does it add weight to the metal itself, it also increases sailing, which is important to consider when mooring, and the inner space of the boules was often used by anglers to store gear, which also affected displacement.
In physics, adding booleans shifts the center of gravity and increases the moment of inertia, making the boat more roller in quiet water, but much safer in the wind, and the mass of metallic linings and reinforced transoms that characterize the boolean models also contribute to the overall weight balance.
When buying used boats with boules, be sure to check the tightness of the compartments - water trapped inside the boules can add tens of kilograms of hidden weight and cause corrosion.
Comparative analysis of the weight of modifications Kazanka-M and Kazanka-5
The most common models with bulges are Kazanka-M and Kazan 5Despite their similarity, their weight specifications vary significantly due to the different dimensions and thickness of the rolled product used. Kazanka-M, being more compact, has a lower mass, which makes it popular for use with low-power engines.
Kazanka-5, in turn, is a larger vessel with increased capacity, with increased length and width requiring a more powerful set and, accordingly, more metal. Weight difference Between these models can be from 40 to 60 kg depending on the year of production and configuration.
The table below shows the weight of the hull for the major modifications, and these figures will help you navigate when choosing a transport for transportation.
| Model boat | Length, m | Width, m. | Boil weight (boules), kg | Load capacity, kg |
|---|---|---|---|---|
| Kazanka-M | 4.50 | 1.60 | ~145 | 400 |
| Kazan 5 | 4.60 | 1.65 | ~190 | 440 |
| Kazankah-5M | 4.60 | 1.65 | ~195 | 440 |
| Kazankah-5M2 | 4.60 | 1.65 | ~200 | 440 |
It is worth noting that the weight in the table is for the base case, and the presence of built-in trunks, reinforced transes or additional bulkheads can increase these values. Soviet engineers Often made changes in the technology of welding and cutting sheet, which also affected the final weight.
Detailed equipment: floorboards, banks and equipment
When we talk about how much a boat weighs, we should not forget about removable equipment. Deck decking (floorboards) is a separate item of expenditure by weight. In Soviet boats paiola was often made of plywood covered with glass fiber or from a thin duraluminum sheet.
Wooden floorboards, although lighter than metal in the dry state, have the property of absorbing moisture. Wet plywood. It can add to the weight of the boat up to 15-20 kg. Metal grooved sheets are heavier, but more durable and do not change the mass depending on the humidity.
- 🪑 Removable cans (seats) usually weigh between 3 and 5 kg each, depending on the material of the manufacture (wood or metal).
- ⚓ The anchor box and the harundukes, if installed stationary, add another 10-15 kg to the total mass.
- 🛡️ Protective linings on cheekbones and keels, popular among owners, can increase weight by 5-8 kg.
When preparing for transportation, it is recommended to weigh the boat in full combat readiness, that is, with floorboards and cans installed, this will give a real idea of the load on the trailer device of the car.
☑️ Pre-weighing check
Effects of Corrosion and Repairs on the Weight of the Body
The age of the boat is not only years of operation, but also the history of its repairs. Duraluminum is susceptible to electrochemical corrosion, especially in contact with water and in the presence of wandering currents. Owners often make cracks or patches using metal thicker than the original board.
Unprofessional repairs can lead to a significant weighting of the structure. Rough patches Welded over rotten areas, they break the balance and increase the weight, and sometimes the weight of the boat after such interventions increases by 10-15% of the original value.
⚠️ Note: The use of steel elements for the repair of duraluminum housing is strictly prohibited, as it causes accelerated galvanic corrosion and destruction of the skin.
Also worth considering is the layer of paint and anti-corrosion coatings. Perennial layers of soil-enamel, especially if the boat was painted "for themselves" without removing the old layers, can add a few pounds. Heavy epoxy compoundsThe stains used to seal the seams also contribute.
How to determine the quality of metal without devices?
Knock on the side with your knuckle. A ringing, clean sound indicates good metal condition and no heavy patches. A deaf sound may indicate a thick layer of putty, rust, or a poor-quality patch.
Transportation and trailer requirements
Knowing the exact weight of the boat Kazanka with boules, you need to choose the right trailer. The total weight of the equipped boat, engine, fuel and the trailer itself should not exceed the maximum permissible mass specified in the PTS of the car.
For Kazanki-M A lightweight single-axle trailer will do well with a 15-20 hp engine, but heavier versions, such as the Kazanka-5M2 with a 30 hp engine, may require a trailer with a braking system. Brake inertia mechanism It is mandatory if the total mass of the trailer with a load exceeds 750 kg.
Remember to distribute the load on the trailer axles evenly. A heavy motor on the transom and a boat with a shifted center of gravity can create a dangerous situation on the road, causing the trailer to wag. Correctly centering the cargo is the key to safe delivery to the reservoir.
The total weight of the boat with boules, motor and equipment often exceeds 300 kg, which requires careful attention to the choice of traction vehicle and the condition of the coupling device.
Practical tips for the operation of heavy modifications
The heavy metal boat has its own specifications, especially when it comes to launching and ashore, and the weight of the bouldered Kazanka makes it quite inert, making it easier to ride the wave, but makes it difficult to maneuver in narrowness in the absence of a motor.
When using powerful motors, it is important to monitor the condition of the transom, the increased mass of the aft part requires regular checks of riveted and welded joints. Vibrations.The suffocation from the heavy motor can weaken the fasteners.
- 🚗 To pull the boat ashore, use a winch with a traction force of at least 1000 kg.
- 🌊 Be aware that a full boat (with water in the hold and boules) may become unmanageable.
- 🔧 Regularly lubricate the hinges and axles, as the load on them is higher than that of light PVC boats.
In conclusion, weight is the price of reliability and survivability of Soviet duraluminium, and proper load calculation and body care will allow you to enjoy fishing for decades.
Can I increase the load capacity of Kazanka with boules?
Theoretically, you can install additional sealed buoyancy blocks, but it will violate the stability and balance laid down by the designers. Any changes to the design must be coordinated with GIMS.
Why is the weight of my boat different from the table?
The difference can be caused by years of repairs, the accumulation of dirt in hard-to-reach places, the replacement of wooden elements with heavier ones, or, conversely, their removal by the owner.
Do I need to remove the boules to reduce weight?
Absolutely not. Booles are a load-bearing element of stability, and their removal will make the boat dangerous to operate, especially when fully loaded or on the turbulence.
