The decision to purchase the classic Soviet Kazanka is often a turning point for many novice water-engineers, and these boats, despite their venerable age, still ply the vast expanses of rivers and lakes, proving their indestructibility and practicality.Buy a boat Kazanka with boulesThis immediately changes things, highlighting a specific and safer modification among a host of other options.
Booles are not just a decorative element, but a serious engineering solution designed to improve the stability of the vessel. Unlike smooth-bore versions, where the boarding could end in a bath, models with welded or glued booles make you feel more confident even with sharp movements of fishermen inside the cockpit, which is why demand for such specimens in the secondary market is consistently high, and the search for a worthy option turns into a kind of treasure hunt.
In this article, we will discuss in detail what to pay attention to if you want to Buy a boat Kazanka with boulesWe'll talk about corrosion, tightness and what engine is optimal for this heavy but reliable aluminum.
Advantages of Boolean design for fishing and recreation
The main reason why you should look for a Boolean version is a radically changed version. stabilityThe classic Kazanka-M or Kazanka-2, without additional buoyancy elements, has a rather narrow bottom and high sides, which creates a high center of gravity. Booles, which are sealed compartments welded to the top of the board, work as outriggers, significantly expanding the effective width of the vessel.
For a fisherman, this means being able to stand up to full height to throw spinning or work with a sonar without fear of flipping over. Kazanka with boules If the smooth-bore version could be fatal to move the trophy pike on one side, the Boolean modification will only slightly tilt, maintaining balance.
⚠️ Warning: Even the presence of boules does not make the boat unsinkable in the event of a breakdown of the main hull. Bulls only increase stability and prevent rapid rolling, but do not replace life jackets and proper loading of the vessel.
In addition, the boules often serve as an additional platform for attaching equipment, conveniently placing anchor lines, attaching safety ends or even installing additional kondukus. For those who plan to use the boat for family walks, the presence of boules is a matter of elementary safety for children who may unconsciously lean on board.
In terms of performance, the bules add sailing, which can be seen in strong side winds, but in glides, this effect is minimal. They have a major effect on the behavior of the boat quietly and when parked. Water in the bules, if the tightness is broken, can be a problem, so checking their condition is a paramount task in the inspection.
The main models of Kazan with factory boules
When you're looking, Buy a boat Kazanka with boulesIt's important to understand that not all models had them in their standard design. The Gorbunov Plant (KAPO) produced various modifications, and the availability of boules often depended on the year of production and the specific series. The most famous model with integrated buoyancy elements is the Kazanka-5 and its modifications, such as Kazanka-5M.
The Kazanka 5 received bouli as a standard safety solution, which allowed it to compete with more modern boats at the time. It is also worth mentioning the Kazanka-2M, which was originally designed as a more seaworthy version, although often owners welded the bulls themselves.
There are also many boats where boules were installed by artisanal method in Soviet times or already today, such options require special careful inspection of welds. Aluminum alloys (AMG5M, AMG5N) are well welded, but a violation of the technology can lead to electrochemical corrosion at the junction of dissimilar metals or using the wrong solder.
The table below compares the main specifications of popular models that are most often encountered with buls:
| Model | Length, m | Breadth with boules, m | Load capacity, kg | Features |
|---|---|---|---|---|
| Kazan 5 | 4.00 | 1.60 | 400 | Factory buls, 12 hp transom. |
| Kazankah-5M | 4.00 | 1.60 | 400 | Reinforced transan, removable cans |
| Kazanka- 2M | 4.50 | 1.60 (with boules) | 500 | More seaworthy, often homemade bules |
| Kazanka-M (tuning) | 3.90 | 1.45 (with boules) | 350 | Basic version with welded elements |
Understanding the differences between the models will help you to formulate a more accurate query when searching for an ad, for example, if you need a trolling boat on a large reservoir, the Kazanka-2M with its elongated hull will be preferable to the short five.
Critical points of corrosion when inspecting used boat
Aluminum is a very capricious material, especially when it comes to the alloys used in shipbuilding in the middle of the last century. Buy a boat Kazanka with boules In the past, 90 percent of your attention should be on corrosion, and the most insidious form of corrosion is intercrystalline corrosion, which may look like a light plaque, but inside turns metal into dust.
First of all, look at the rivets. Rivets are the weak spot of any Kazanka, and they often form oxides and leaks around them. Pay special attention to the zygomatic guides (the angles of the bottom and the side) and the transom. This is where moisture and dirt most often accumulate, which accelerates the destruction of metal. If you see paint bloating or white fluffy plaque, it's a bad sign.
Use a regular school eraser to clean a suspicious area. Rub the metal: if the oxide is left deep shells or the metal crumbles, you can't take the boat.
Bullies also require careful inspection. Because they are closed volumes, condensate can accumulate inside them. If the previous owner did not make drainage holes or seal them properly, the boules can rot for years inside. Knock on them: a ringing sound — good, deaf — maybe there is already peeled metal or cracks.
⚠️ Warning: Never buy a boat if the transom has signs of rotting or deformation. This is the zone of maximum load from the engine, and its destruction on the go will lead to engine loss and possible accident.
Notice the bottom. The dents themselves are not scary if there are no cracks. Aluminum is plastic. But if the dent is on the edge of the stiffness or in the riveting place, the integrity of the structure can be disrupted. The curvature of the seam lines is a sign that the boat once "twisted" when hitting the brow or when transported improperly.
Evaluation of welded seams and tightness
The sealing is what separates the boat from the bucket. When inspecting a boat with boules, it is important to check not only the factory seams, but also the repair seams. Often previous owners boiled the boat with argon, but not always qualitatively. If the seam has an uneven scaly, pores or color transitions (rainbow), this may indicate that the metal is overheated and disturbed its structure.
Dry seal testing is difficult, but it's possible. Put water in the bow and cockpit, leave the boat for a few hours, and see if the drops come from below. Pay special attention to the junction of the boules with the main body, which is where microcracks occur most often due to the different rigidities of the structures in choppy conditions.
If you're not sure about your abilities, you might want to hire an experienced welder or use penetrants to look for microcracks. Buying a boat is an investment, and the cost of diagnostics can translate into costly repairs in the high season. Remember, you can make a hole in the bottom, but you can't restore lost metal and its properties.
☑️ Checking the boat before buying
It's also important to check if the repairs were lead or tin instead of aluminum, which is when paired with aluminum in seawater or even river water, creates a galvanic pair where aluminum breaks down very quickly, and if the seam looks like a solid gray metal, different from silver aluminum, that's a good thing to be wary of.
Selection of motor for Kazanka with boules
Choosing an engine for Kazanka is always a compromise between the weight of the boat and the power of the engine. Kazanka is a heavy boat with a flat bottom, so it requires sufficient traction to go into plane with two passengers and cargo. The standard solution for models with bulas (for example, Kazanka-5) are engines with a capacity of 8 to 12 hp.
However, if you plan to use a boat for trolling or quiet fishing with one person, 5-6 hp is enough. Kazanka with boules It has a lot of sailing and resistance, so a weak motor will dig water, but not accelerate the boat, which increases fuel consumption and engine wear.
When installing the motor on the Kazanka transom, be sure to use a sub-motor board if the standard transom looks questionable or does not have sufficient height. Modern four-stroke engines are heavier than two-stroke analogues, which can shift the center of gravity and drown out the transom. Booles help compensate for roll, but do not always save from the stern different.
Can I put a motor more powerful than 12 hp?
Formally, for Kazanka-5, the restriction is 12 hp Installation of a more powerful engine (for example, 15 hp) is possible, but requires registration in the GIMS as a conversion and carries the risk of destroying the transom. In addition, such a heavy boat with a powerful engine can go out with a dangerous angle of the trim (on the nose), which is fraught with the overlap of the wave across the board.
For those who appreciate silence and economy, modern 4-strokes are a great choice, but prepare for the fact that the boat will sit deeper in the water. If dynamics and the ability to quickly get to the point are important, a two-stroke engine of 9.9 hp (often programmed to 15-18 hp by craftsmen, although this is risky) will become a “golden mean”.
Legal aspects and registration in GIMS
Buying a used metal boat is not only technical, but also legal: the main rule is that the boat must be deregistered by the previous owner, or you must formalize the contract of sale correctly for subsequent registration for yourself.
When registering a boat with boules, questions may arise if the boules are installed independently and are not inscribed in the design. The GIMS inspector may require a certificate for materials or an inspection certificate confirming the safety of modifications. Factory boules are usually not problematic, since they are indicated in the product passport.
It is important to check the boat number on the transom, it should read clearly and match the number in the documents, if the number is corroded or interrupted, this is a path to denial of registration and possible seizure of the boat, and also make sure that the boat is not listed as stolen, although for old Kazanok this is rare.
Without a valid boat's ticket and a sales contract, you only buy metal, not the right to sail. Always demand a full package of documents.
Keep in mind that since 2012 boats under 3 meters long and weighing up to 200 kg (including the engine) do not require registration, but the Booles and motor Kazanka almost always exceeds this weight limit, so registration is mandatory. Annual inspection is another procedure to be prepared for.
Frequently Asked Questions (FAQ)
How much can a used Kazanka with boules in good condition cost?
Prices vary greatly by region, year of manufacture and configuration, with average prices ranging from 15,000 to 40,000 rubles, boats with a new tent, fresh transom and complete with an engine can cost more, and it is important to evaluate the condition of the metal, not the presence of a beautiful awning.
Can I make a crack in Kazanka on my own?
You can, if you have argon welding skills and a suitable additive (usually AMG5 or AMG6). However, for the places in charge (bone, transom), it is better to contact professionals. Incorrect welding can lead to the release of metal and the appearance of new cracks near the seam.
What is the maximum wave size for Kazanka with boules?
Kazanka is a B-class vessel (inland waters) and can handle up to 0.6 meters. The presence of boules improves wave behavior, but does not change the category of the vessel.
Do I need to paint the garment after buying?
If the factory coating is intact, it's free of bubbles and chips to metal, you don't have to paint it. You just need to polish it. If there are corrosion hot spots, cleaning and painting with epoxy soils and aluminum paints will extend the life of the boat for years.
Which is better: Kazanka with boules or PVC boat?
It's a matter of preference. PVC is lighter, doesn't require registration (small models) and isn't afraid of bumps. Kazanka is stronger, allows you to stand up full-length, is not afraid of sparks from fires and hooks, but it is heavier in transport and prone to corrosion. For large ponds and trolling Kazanka often wins.
