Legendary KazankaThe raft, which emerged in the late 1950s, became a true symbol of affordable water transport for millions of Soviet citizens, and it was this model that ushered in the era of mass-scale small fleets, allowing ordinary people to go out on reliable metal boats, but the first versions had a significant disadvantage - the lack of floating boules, which made them unsafe when they were very worried or rolled.
Modifications Kazanka M The welded boules were the designers' response to safety and water-powered demands, and this version was widely adopted thanks to improved stability and the ability to install more powerful engines. Technical specifications This boat still arouses a keen interest among collectors and fans of retro equipment, as well as those who are looking for a simple and maintainable option for fishing.
In this article, we will discuss in detail how the model with boules differs from the classic version, consider its real capabilities on the water and discuss the nuances of operating aluminum-magnesium alloys in modern conditions. You will learn why this hull has survived many modern analogues and how to properly approach the restoration or purchase of such a vessel today.
History of creation and design features
Development Kazan It was conducted at the Kazan Gorbunov Aviation Plant, where aircraft technology for light alloy production was adapted for shipbuilding. Kazanka The boat, which was built in 1955, was quickly criticized for its low stability, and experienced water-engineers remember that without the boules, the boat was prone to a sharp roll and even tipping when entering the planing or abruptly moving passengers.
Upgraded version Kazanka MThe buoy, which was made with welded boules, was introduced in 1961 and was produced until the 1970s, and was structurally an all-welded body made of AMG5M aluminum-magnesium alloy. Bouli This modification was designed to provide additional buoyancy on the sides, which dramatically changed the behavior of the vessel on the water, not only increased stability, but also allowed to increase the permissible power of the outboard motor.
The boat's hull has a flat bottom with a slight uplift to the nose, which is typical of the sleeving vessels of the time. Welds were made by argon-arc welding, which ensured high tightness and strength of joints. However, it is welds that often become the object of attention when buying a used copy, since over time in areas of thermal influence can corrosion.
⚠️ Note: When inspecting the old Kazan M. First of all, check the condition of the welding of the boules to the sides, and this is where cracks most often occur due to metal fatigue and shocks against the wave.
It's important to note that the manufacturing technology of those years was manually assembled, so the geometry of the case could vary slightly from one instance to another. hull strength remained at a high level, allowing boats to survive blows to the sinkers and coastal surf, which would be fatal for fiberglass counterparts.
Technical specifications and dimensions
To understand the real possibilities Kazan M. The size of the vessel allows you to classify it as a small rowing boat or motor boat to protect against the waves in coastal zones. Despite its weight by modern standards, the hull has excellent inertia, which helps smooth out the small chop wave.
Below is a table with the main technical data that will help you navigate the possibilities of this model:
| Parameter | Meaning |
|---|---|
| Maximum length | 4,000 mm |
| maximum width | 1500 mm |
| Height on midship | 550 mm |
| Load capacity | 400 kg |
| Weight of the body without equipment | 84 kg |
Notice the weight-to-load ratio, which is 84kg, and it can carry up to 400kg of payload, which means you can comfortably accommodate three adults with a minimum of gear, but it's a challenge to go out and plane.
The passport has a capacity of 4 people, but this is only true for quiet water and low speeds. Real exploitation It shows that for a safe and comfortable ride with the engine, the optimal number of passengers is two, in which case the boat behaves predictably and easily enters planing mode.
⚠️ Attention: Never exceed the rated carrying capacity of 400 kg. Aluminum alloy AMg5M, although durable, loses driving qualities when overloaded, and the risk of flooding with a wave through a low transom increases many times.
The truncheon of the boat is designed to install an outboard motor with a capacity of up to 8-10 hp (depending on the year of production and modification of the transom). More powerful engines can be installed, but this requires serious refinement of the aft part and understanding of the risks associated with the strength of the transom board and skin.
Driving and handling
Driving performance Kazan M. The flat bottom provides excellent wave germination at low speeds, but when it is fully glided, it starts to slap the wave, causing discomfort to the crew, which is the price of simplicity and technological production in the middle of the last century.
The presence of boules changes the behavior of the boat on the course. Kazanka It would be a very rolling stock, but with welded volumes, it becomes a stable platform. Resilience It allows fishermen to move around the cockpit, doing tackles, without the risk of overturning, but it is worth remembering that the sailing speed of the boat is high due to the vertical sides.
At speeds above 25-30 km/h, the boat is prone to yaw, especially in lateral winds. Steering requires constant attention and steering. Many owners note that as the engine increases, the boat becomes more docile, as the flow of water tightens the flat bottom.
To improve performance, many owners install longitudinal redans (zygomatic stringers) made of aluminum corner on the bottom, which helps stabilize the course and reduce yaw at high speeds.
Materials and durability of the body
The main material of the case is the alloy AMg5M, aluminum-magnesium alloy in a soft (burned) state, and this material was chosen not by chance: it has high corrosion resistance in sea and fresh water, as well as good weldability. Kazan They have survived to this day, keeping their tightness.
But aluminum has enemies that we must not forget, chief among them being electrochemical corrosion, which occurs when it comes into contact with other metals in water. galvanic pair can quickly destroy the skin, for example, if you use steel bolts instead of aluminum or dural during repair.
Also worth mentioning is a phenomenon known as "hydrogen disease" or intercrystalline corrosion, although it is less common for an AMG5M alloy than for duraluminium. The main destruction is due to mechanical damage to the protective oxide film and the wandering currents if the boat is stored on water with electrical input.
How to extend the life of an aluminum case?
An aluminum hull requires annual washing and inspection. It's important not to use abrasive brushes that scratch the oxide film. The best protection is clean and dry when stored. If the boat is standing on the water, you must install zinc treads.
Features of operation and storage
Operation Kazan M. It requires certain rules, which are dictated by the design, and it's primarily about storage, and aluminum doesn't rot like wood, and it doesn't stratify like fiberglass, but it's softer than steel, and it's best to keep it under a canopy or in a garage, to prevent the constant exposure of ultraviolet light to rubber elements and the accumulation of moisture inside the hull.
When transporting on a trailer, the weight of the boat must be taken into account. 84 kg is quite a lot for one person, so descent and ascent often require help or the use of a winch. kylson The frames are distributed along the length of the hull, which allows you to put the boat on a slip or keel blocks without the risk of deformation, but the points of support must be correctly chosen.
Winter storage requires no special conditions other than dryness. Aluminum is not afraid of frost, but rubber seals and wooden elements (if they are included, such as paiola) can suffer. It is recommended to remove all removable equipment and leave the hatches open for ventilation.
☑️ Preparation for winter storage
Repair and modernization: experience of owners
Repairs Kazan This is a separate topic of conversation, because the design of the boat is creative, most often owners are faced with the need to weld cracks in the area of welding boules or replacing rotten wooden floorboards, welding uses argon, which requires the appropriate equipment and skills.
A popular trend of tuning is the installation of windscreen and awning, and the boat was not equipped with a full cockpit, so owners make their own frames from dural pipes and stretch PVC awnings, which greatly improves comfort when driving in the rain and wind.
Another common upgrade is the expansion of the harunduks and the installation of soft seats. Staff hard cans are inconvenient for long transitions, many are replacing them with soft modules with built-in gearboxes, which simultaneously solves the problem of comfort and storage.
⚠️ Warning: When welding on the case, be sure to use argon welding. The use of electrodes or gas welding for fine aluminum AMg5M is unacceptable and will lead to burnout and loss of strength of the seam.
Some enthusiasts go further and install hydrowings on the legs of the engine, which allows earlier plane and reduces the load on the transom, and there is also the installation of additional fuel tanks in the nose for balancing, since a regular tank is often not enough for long fishing.
Comparison with modern analogues
Comparison Kazanka M With modern PVC or fiberglass boats, you can go on forever, but each era has its own requirements. Modern inflatable boats are gaining in weight and transportability, but they are losing in durability and the ability to install powerful equipment. Kazanka It remains a “workhorse”, which is not afraid of either snags or rocky bottom.
Fiberglass models offer better comfort and design, but they're virtually impossible to repair in the field, and the price is often many times higher. Aluminum housing can be brewed or patched in almost any environment with a minimum set of tools. Kazanka The ideal choice for remote regions and harsh exploitation.
If you are looking for a boat for a quiet fishing on the lake, where peace and stability are important, and you are ready to put up with excess weight for the sake of reliability - Kazanka M It's still relevant today, and it doesn't require special storage conditions like some composite materials, and it lasts for decades with minimal maintenance.
Which motor is best for Kazanka M?
The optimal choice is the engines with a capacity of 5-8 hp (Yamaha, Tohatsu, Mercury) or the Soviet "Veterok-8". They allow you to reach a speed of about 25-30 km / h with one or two passengers. Motors more powerful than 10 hp can be installed, but this requires strengthening the transom and experience of management, since the boat can begin to "goat".
Can I use the Kazanka at sea?
It's only possible to use it in the coastal zone at calm, flat bottom and low sides, not for sea waves. Kazanka prohibited by the rules of GIMS and life-threatening because of the risk of overturning.
How to deal with leakage in welds?
Small leaks can be eliminated with special sealants for aluminum or epoxy compounds with aluminum powder. However, major repairs require stripping the seam to the metal and digesting with argon. It is important to find the cause of corrosion, otherwise the leak will appear again.
Should I paint an aluminum boat?
It is not recommended to paint an aluminum case with ordinary paint, as it will quickly peel off due to oxidation. If the appearance is critical, special soils for non-ferrous metals and polyurethane enamel are used. However, many owners leave the boat in its natural form, since the oxide film itself is protective.
