The legendary Kazanka-5M2 remains one of the most popular aluminum boats in the post-Soviet space, despite the age of the design. overallity This is a crucial factor in the choice of a boat, and understanding the exact dimensions is necessary not only to assess internal comfort, but also to find the right trailer, garage space and, of course, the right power calculation of the outboard motor.
Unlike earlier versions, this modification received an elongated nasal part, which radically changed it. seaworthinessThe standard length of the hull makes you feel confident in the wave, but the physical dimensions impose certain restrictions on transportation, and you will need to consider not only the length of the waterline, but also the total length, taking into account the transom and possible improvements if you plan long trips.
In this article we will analyze all linear parameters in detail, give exact figures from the manufacturer's technical documentation and compare them with real measurements of owners. Kazan 5M2 It is a balance between roominess and maneuverability, but for this balance to work, you need to know clearly what dimensions you will have to deal with.
The main dimensions of the body and their impact on driving performance
The fundamental parameter that determines the class of the boat is its length. For the 5M2 model, this figure is exactly the same. 5000 mm This is 40 cm more than the 5M predecessor, and this increase has significantly improved the running stability. The elongated nose is better at cutting the wave, reducing the shock load on the body and passengers when driving against the wind.
The mid-hull has also changed from previous models to 1600 mm, a value critical to parking stability. The wider body allows even two adults to safely navigate the deck, which is often necessary when catching large fish or installing additional equipment. However, the increased width creates greater water resistance, which requires a more powerful engine to go to the planing.
The height of the midship is 720 mm, which is quite high for a boat of this class, ensuring dryness in the cockpit even in strong lateral winds. However, the high side increases sailing, which must be considered when driving a boat in stormy weather. Shell parameters They are selected to maximize usable volume while maintaining acceptable speed specifications.
Detailed analysis of the size of the cockpit and useful area
The interior of the boat is the area where you spend all the time fishing or cruising. The size of the cockpit is directly dependent on the outer geometry of the hull and the thickness of the aluminum alloy used. The useful length of the cockpit from the transom to the forepeak is about 4200 mm. This space is usually divided into several compartments, including the runducts and the leg area of passengers.
The width of the cockpit in the widest part (on the midfield) reaches 1400-1450 mm, if you take into account the inner skin and cans, this distance allows you to comfortably place two fishing boxes on the sides or install a transom jar for three people, although sitting three times on a rigid bench will be cramped. optimalallowing you to freely operate spinning without the risk of hooking a neighbor.
⚠️ Note: When calculating usable area, remember that installing additional elements, such as a control console or windshield, can visually and physically reduce the available space in the bow of the cockpit.
The height from the bottom to the top of the side inside the boat allows you to fish standing up, which is important for many fishing techniques. However, it is worth remembering the weight distribution: if all passengers stand up at the same time, the center of gravity will shift, which can affect the trim. ergonomics The placement of equipment helps to compensate for these fluctuations.
To increase the usable area in the nose, you can dismantle the standard forepeak and install removable gearboxes there, which will serve as additional seats.
specifications of the transom and requirements for the outboard motor
The Kazanka-5M2 has a standard suspension height of 400 mm (15 inches) from the top edge of the lower unit to the bottom of the transom, a classic size for most medium-power outboard motors, with a transom width of about 400-420 mm on the top edge, allowing a wide lower unit leg motor to be mounted without the risk of overboard.
The most important parameter is the permissible power of the engine. The manufacturer initially recommended engines with a capacity of up to 25 hp, but the practice of operation and strengthening the transom by the owners allowed the use of engines up to 30-35 hp. transmutation Or even a motor pullaway at high speeds, which creates an emergency situation.
The transom angle also plays a role in the formation of the running trim, designed to work with engines that have a standard angle of reclining on the Kazanka, and when installing powerful motors, it is often necessary to adjust the slope with washers or hydraulic stops so that the boat does not burrow or, conversely, does not rust.
Maximum safe engine power for the standard transom Kazanka-5M2 without modifications is 25-30 hp Installation of more powerful units requires mandatory strengthening of the transom steel sheets or profile.
Weight specifications and load capacity
The weight of an empty boat is one of the key factors influencing the choice of vehicle for towing. the hull of Kazanka-5M2 with equipment (tiller, banks, windshield) is about 150 kg. It is quite heavy boat for carrying by hand, so the presence of a wheeled trailer or crane beam for launching is almost necessary.
The boat's full load capacity is limited to 400 kg, which includes the weight of passengers, engine, fuel, equipment and hull, and if you subtract the weight of the boat (150 kg) and the approximate weight of the engine with the tank (about 50-60 kg), the payload remains about 190-200 kg, which corresponds to the weight of two adults and a small number of tackles.
Below is a table of weight distribution for a typical use case:
| Component | Approximate weight (kg) | Influence on the centre of gravity |
|---|---|---|
| Boat hull | 150 | Uniform |
| Outboard motor (30 hp) | 48 | Feed (negative different) |
| Full tank (25 l) | 19 | Aft/Borth |
| Two passengers. | 160 | Central/Nose |
It is important to understand that uneven distribution of cargo can lead to dangerous rollThe aluminum body has a certain flexibility, and the constant overload of one side can cause residual deformation of the frames.
Transportation: dimensions on the trailer and road restrictions
In preparation for transportation, you need to consider not only the length of the boat itself, but also the length of the trailer, as well as the possible overhang of the engine. The total length of the boat + trailer bundle usually does not exceed 6 meters, which allows it to be towed by a B-class passenger car without special permits. However, the width of the trailer is often equal to or slightly more than the width of the boat - about 1650 mm.
The height of the boat on the trailer depends on the type of lodging or roller supports. Standard height of the side of the 720 mm plus the height of the side of the trailer gives approximately 900-1000 mm from the ground to the top section of the side. If the windshield is installed, the height should be increased by another 400-500 mm. This is important when driving under low arches, barriers or entering low garages.
⚠️ Attention: When transporting over long distances, be sure to use a running belt through the keel to exclude the longitudinal displacement of the boat on inertia during braking, even if it is fixed with a nose stop.
Weight of the equipped trailer with a boat, engine and fuel will be about 250-280 kg. This fits into the standard limits for passenger cars, but requires a serviceable braking system of the trailer, especially when driving on mountain roads or protracted descents.

Comparison of dimensions of Kazanka 5M and 5M2
Many aftermarket buyers face a choice between the classic five and its elongated version, with the main difference being that the 5M is 40 cm shorter (4,600 mm vs. 5000 mm) that seems small on paper, but on water it feels like a seaworthiness class. The 5M2's elongated nose provides better germination per wave.
The width of both models is almost identical, but the 5M2 has a sharper nose shape, which reduces water resistance. The 5M2 has a larger internal volume, which allows more equipment to be placed for multi-day hikes. However, the 5M2 version has a weight of about 10-15 kg higher due to the use of more metal.
If you plan to walk on large reservoirs with high waves, the choice in favor of 5M2 is obvious. For small rivers and lakes, where compact storage and easy running at low power are important, the classic 5M may be more practical. Boat sizes It must always be in accordance with the operating conditions.
The Secret of Modernization
Some 5M owners independently build up the nose, welding additional dural sheets to get the specifications of 5M2, but this method requires high qualification of the welder and careful sealing of the seams.
Frequently Asked Questions (FAQ)
Can I install a 40 hp engine on Kazanka 5M2?
Formally, the factory instruction limits the power of 25-30 hp Installation of a 40-horsepower engine is possible only if the transax is seriously strengthened (cooking additional sheets of aluminum or profiles) and the availability of appropriate driving skills. Without strengthening, the risk of tearing off the transompan or destroying the stern part of the body at speed is high.
What is the real speed of a boat with a 30 hp engine?
At full load (two people, equipment, tank) Kazan 5M2 with a 30 hp engine develops a speed of about 35-40 km / h With one driver and a full tank, the speed can reach 45-48 km / h. The speed depends heavily on the state of the bottom (the presence of fouling), the type of screw and load.
Do I need to register Kazanka 5M2 in GIMS?
The weight of the equipped boat (150 kg) plus the engine weight (more than 50 kg) exceeds 200 kg. According to the current legislation of the Russian Federation, boats with a mass of more than 200 kg or with an engine capacity of more than 8 kW (about 10.8 hp) are subject to mandatory registration.
How many people can hold a boat on a passport?
The passenger capacity of Kazanka 5M2 is usually indicated as 4 people, however, this is only true for calm water and with a minimum amount of equipment. For comfortable and safe fishing with a full set of gear, a crew of 2 people is considered optimal.
