Brand boats "Kazanka" - legendary domestic boats, known for their strength and versatility. transportationThe first question that concerns the owners: How much does the Kazanka weigh with boules? After all, it is the buli (onboard floats) that add additional mass, affecting the overall weight, stability and even the carrying capacity of the boat.

In this article, we will discuss weight-figure For all popular models of Kazanka (from the KM-2 before KM-5) with boules, compare them to float-free counterparts and give practical tips on transportation. myths about the effect of boules on speed We will tell you how to distribute the load correctly so as not to overload the boat.

If you are planning to buy or are already a happy owner of Kazanka, this information will help to avoid errors in transportation, registration with the GIMS and even when choosing a motor.

1. The weight of the Kazanka with boules: official data on models

Manufacturer-- OJSC Kazan Plant of Rubber Products - indicates the weight of the boats boulelessHowever, in the configuration with floats, the mass increases by 8-12 kg Below is the current table of weights with standard boules (polyurethane foam or foam).

Model boat Boolean weight (kg) Boolean weight (kg) Permissible load (kg) Length (m)
Kazan KM-2 28–30 35–37 275 2.6
Kazan KM-3 35–37 42–45 385 3.1
Kazanka KM-4 40–42 48–50 430 3.6
Kazanka KM-5 48–50 53–55 500 4.1

Important: Weight can vary by ±2 kg depending on the material of the boules (foam lighter than polyurethane foam) and the year of the boat's release. Kazan until 2010 Sometimes they are equipped with heavier boules due to a thickened layer of skin.

The most important thing is that boats with bulas weigh 20-25% more than without them. Passport load capacity is not reduced Floats are considered part of the construction. This means you can load the boat at the maximum permissible weight without fear of exceeding the limit.

2. Why Booleans Increase Weight and How It Affects the Boat

Booley is float-boardThey're attached to the perimeter of the boat, and their primary function is:

  • 🛟️ Enhancing sustainability prevents rollover during wave or sharp turns.
  • 🚤 Improvement of driving performance Reduce water spray and resistance at high speed.
  • 🔧 Additional buoyancy Helps keep the boat afloat even when it is flooded.

But these benefits are paid for by extra weight. one boulevard weighs 2-3 kgThe number depends on the model:

  • 🔹 KM-2 4 boules (2 on each side).
  • 🔹 KM-3/KM-4 - 6 boules (3 on board).
  • 🔹 KM-5 - 8 boules (4 each from the side).

In addition, the bulges affect the centre-upIf they are set asymmetrically (for example, one buel is heavier than another), this can lead to the rollTherefore, before the first release on the water, it is recommended to check the balance:

Make sure all the boobys are the same size and weight |

Check the symmetry of the mounts |

Distribute the cargo evenly along the length of the boat |

Conduct a test run at low speed--

Myth debunked: Many people think that the Booles are a big drag on the boat. not more than 2-3 km/h when using the engine up to 15 hp On more powerful engines (20+ hp) the difference is almost imperceptible.

3. How to properly transport the Kazanka with boules

The increased weight of the boat with the boules requires a special approach to transportation.

🚗 Car trailer:

  • 🔧 Use a trailer with a load capacity at least 200 kg (even for) KM-2).
  • 📏 Fix the boat in. 4-5 pointsThe nose, the stern and the sides (so that the sterns do not move).
  • 🛠️ Check the pressure in the wheels of the trailer – it should be on 0.2–0.3 atm above standard (Indicated in the trailer instructions).

🚶 Handheld:

  • 💪 For KM-3/KM-4 need 2-3 people (The weight of 45-50 kg is difficult to lift alone).
  • 🎒 Use it. strap For carrying boats, they distribute the load on the shoulders.
  • ⚠️ Don’t take the boat by the boules – they can break away from the fasteners!

✈️ Transportation on the roof of the car:

⚠️ Attention: Boats KM-4 and KM-5 bulgey more than 50 kg Most passenger cars are not designed to handle this load on the roof. 75 kgHowever, due to the aerodynamics, it is recommended not to exceed 50 kg.

If you decide to take a boat on the roof, follow the instructions:

  1. Use it. tension-belt (minimum 4 grand).
  2. Secure the boat. bottom-up - it'll reduce air resistance.
  3. Check the mounts every time. 100–150 km Ways.
💡

If you're transporting a boat over long distances, take off the boules and carry them separately in the trunk, which will reduce weight by 10-15 kg and reduce the risk of damage.

4. The effect of weight on registration in GIMS

I agree. Order of the Ministry of Emergency Situations No. 496 (from 2020), boats weighing more than 200 kg motorized over 10.88 hp (8 kW) They are subject to mandatory registration with the GIMS, but there are nuances:

✅ "Kazanka" with boules is NOT subject to registration, if:

  • 🔹 Her weight with motor and equipment less than 200 kg.
  • 🔹 Engine power until 10.88 hp. (Even if the boat weighs 190 kg).

❌ Registration is mandatory, if:

  • 🔹 Engine installed over 10.88 hp (for example, Yamaha 15 or Mercury 20).
  • 🔹 Total weight of the boat + engine + equipment exceeds 200 kg (relevantly) KM-5 with a heavy motor and a battery.

⚠️ Attention: When registering with GIMS, the weight of the boat is indicated bulgeyIf you take off the bullets before weighing, it could be considered an attempt to cheat - the inspector has the right to refuse registration.

Example of calculation Kazan KM-4:

  • Weight of the boat with the boules: 50 kg.
  • Motor. Tohatsu 9.8: 26 kg.
  • Battery, fuel, gear: 30 kg.
  • Total: 106 kg → No registration required.

If you put the motor on Mercury 15 weight 36 kg) the total weight shall be 116 kgBut because of the power >10.88 hp registration will become mandatory.

5 How to reduce the weight of Kazanka without losing functionality

If it's difficult to transport a boat with bulae, you can optimize its weight without compromising safety.

🔧 Replacement of boules with lightweight:

  • 🔹 Standard polyurethane foam bules weigh 2.5–3 kg Every analogue from polystyrene (for example, Penoplexlighter 30–40%.
  • 🔹 Replacement cost: 1.5-2,000 rubles. The boat (depending on the model of the boat).

🧳 Optimization of equipment:

  • 🔹 Use it. compact-battery (Lithium-ion instead of lead-acid).
  • 🔹 Replace the heavy box with a waterproof.
  • 🔹 Take it. anchor instead of cast (savings up to 5 kg).

🛠️ Upgrade of anchorages:

  • 🔹 Install. quick-removal for bulae (e.g. from Harken or RonstanThis will allow you to remove floats for 2-3 minutes before transport.
  • 🔹 Use it. aluminum-stack instead of steel (savings of ~1 kg per set).

⚠️ Attention: Don't remove the bulges completely for weight loss! data-sheet specifications of the boat It can lead to a rollover. 30% of accidents with Kazankah They occur due to the absence of boules at a wave of more than 0.5 m.
What happens if you drive without boules?

Without boules, the boat becomes less stable, especially when bends or waves are sharp, the risk of tipping increases 3-4 times, and spray from the bow of the boat will flood the cabin, and at high speed, the stern can “fly” (the “water planning” effect), which can lead to loss of control.

6. Comparison of Kazanka with and without boules: what to choose

To determine whether you need a boat, compare the key parameters:

Parameter With boules. No boules.
Weight (by example) KM-3) 42-45 kg 35-37 kg
Resilience on the wave ⭐⭐⭐⭐⭐ ⭐⭐
Maximum speed (with engine 9.9 hp) 38-40 km/h 40-42 km/h
Difficulty of transportation Demands 2-3 people. You can carry it alone.
Splash protection High. Low.

Conclusion: bulges are necessaryIf you:

  • 🌊 Walk on large bodies of water with a wave (rivers, lakes, sea).
  • 🎣 Fish in windy weather.
  • 🚤 Use a motor with a capacity of more than 5 hp

You can do without the boules only if:

  • 🏞️ Swim in calm ponds or small rivers.
  • 🚣 Use the boat for quiet hunting or short journeys.
  • 💪 They are willing to sacrifice stability for ease of transportation.
💡

Bulls add weight, but their benefits outweigh the inconveniences. For 90% of Kazanok owners, they are mandatory - especially if the boat is used with a motor or in open water.

7. Frequent errors in the operation of the Kazanka with boules

Even experienced water-engineers sometimes make mistakes that lead to breakdowns or accidents.

🔴 Incorrect attachment of boules:

  • 🔹 Use of the plastic-hitch They're not metal fasteners, and when they're loaded, they burst, and the boules fall off as they go.
  • 🔹 Bolt-twisting washerless This leads to the hull of the boat being broken.

🔴 Overloading of the boat:

  • 🔹 Excess of passport load capacity by 20–30% (e.g. 500 kg instead of 430 kg for KM-4It leads to bottom-deformation and the risk of flooding.
  • 🔹 Placement of the goods in side-boat It's a balance-breaker, and it can lead to rolling.

🔴 Ignoring the technical condition:

  • 🔹 Operation of a boat from bula-crackThe foam gets wet and loses its buoyancy over time.
  • 🔹 Absence fixation Rusty bolts or loose nuts are a common cause of accidents.

🛑 What to do if the bull breaks off on the move?

  1. Immediately. slow down to the minimum.
  2. Check if the broken-off boulder has been damaged. boat hull.
  3. If the boulder is lost, back on shore Further navigation is not safe.

💡 Expert advice:

💡

Once a season, check the buoyancy: put them in the water for 10-15 minutes. If they start to sink or get very wet, you need to replace them.

FAQ: Answers to frequent questions

❓ Can I install the boules on the Kazanka independently if they were not included in the kit?

Yeah, but it'll take:

  • 🔹 Set of boules (cost from 3 to 6 thousand RUB. depending on the model).
  • 🔹 The stainless steel and the stainless steel are better.
  • 🔹 Sealer for handling holes (for example, Sikaflex-291).

The diagram is in the boat's manual, so the key is not to drill the holes closer than the boat. 5cm from the seamSo as not to weaken the structure.

❓ How much weight do the boules weigh apart from the boat?

The weight of one boulder depends on the material and size:

  • 🔹 For KM-2/KM-3: 2.5 kg (foam) or 2.5–3 kg (Peam polyurethane)
  • 🔹 For KM-4/KM-5: 3.5 kg (because of the larger volume).

A set of 6 boules for KM-3 weigh 15–18 kgfor KM-5 (8 boules) 20-24 kg.

❓ Does the weight of the boules affect fuel consumption?

Yes, but not much, according to the owner's test:

  • 🔹 On the motor. 5-9.9 hp expense 0.3–0.5 l/hour.
  • 🔹 On the motor. 15-20 hp. difference 0.1-0.2 l/hour (Because of the better scalability with the scalp).

For comparison, wind or current affect fuel consumption much more than buls.

❓ Is it possible to register the Kazanka with boules as a small-sized vessel if the weight is less than 200 kg, but the engine is 15 hp?

Yes, in this case, registration mandatorybecause the criterion is motor-power (over 10.88 hp) rather than the weight of the boat. Even if the total weight of the boat with the equipment is 150 kg, the presence of the engine > 10.88 hp requires registration in GIMS.

❓ Which trailer is suitable for transporting Kazanka KM-5 with boules?

Recommended trailer parameters:

  • 🔹 Load capacity: 300kg (with a reserve for motor and equipment).
  • 🔹 Lodge length: at least 4.5 m (to keep the boat from hanging).
  • 🔹 Material: Galvanized steel or aluminum (for protection against corrosion).
  • 🔹 Presence roller-rotor for easy loading.
