Boat. "Progress 4." It is one of the most popular models among domestic aluminum vessels, combining simplicity of design, reliability and affordable price. How much does this boat weigh? The answer depends not only on the choice of vehicle for transportation, but also on water safety, as well as compliance with GIMS requirements.
In this article, we will discuss weight-report Comparisons with competitors (e.g., Kazanka-4M. or Ob-4.), and also give practical recommendations for optimization of load. The most important nuances that manufacturers often do not mention: how weight affects the stability of the wave and why overloading even 50 kg can lead to dangerous consequences..
Technical specifications of "Progress 4": official data
According to the data-sheet figures of the manufacturer (OJSC "Votkinsky plant"), the boat "Progress 4." In standard configuration has the following parameters:
- 📏 Length: 4.0 m
- 📐 Width: 1.55 m m
- ⚖️ Weight of the body (without motor and equipment): 120-130 kg
- 🚤 Maximum engine power: 25 hp.
- 👥 Passenger capacity: 4 people
- 📦 Load capacity: 400 kg
It is important to understand that specified weight 120-130 kg - is the mass of the "bare" body of aluminum-magnesium alloy AMG5 And without transom, without seats, without sealants, without any other things, in reality, even a new boat without an engine weighs. 140-150 kgwith an installed outboard motor (e.g., "Whirlwind 25") and the fuel tank easily exceeds the mass of 200 kg.
⚠️ Attention: The manufacturer often indicates weight without taking into accountsquirrel-wheel,anchorandfunWhen buying a used boat, add another +15-20 kg to the data-sheet figures for rust, paint and homemade improvements.
How weight affects transportation and operation
Boat mass "Progress 4." directly determines:
- Selection of vehicle. A passenger car with a farcop is sufficient for carriage on a trailer (for example, Lada Largus or Renault Duster) but if the weight exceeds 200 kg, a reinforced coupling and a check of the braking system will be required.
- Speed and maneuverability on the water. The heavier the boat, the worse it obeys the steering wheel at low speeds and the more fuel the engine consumes.
- Resilience in the wave. An overloaded boat risks “dive” nose into the wave or lose stability in a sharp turn.
Example: if you plan to fish in a lake with a wave of up to 0.5 m, then the weight of up to 200 kg will be optimal. Volga or kama) better to fit in 160–180 kgTo keep it manageable.
| Parameter | Progress 4 (120-150 kg) | Kazanka-4M (140-160 kg) | Ob-4 (130-155 kg) |
|---|---|---|---|
| Max, engine power. | 25 hp | 30 hp | 20 hp |
| Passenger capacity | 4 people. | 4 people. | 3 people. |
| Recommended weight for the river | 180 kg | 200 kg | 170 kg |
| Average fuel consumption (per 10 km) | 1.2–1.5 l | 1.5–1.8 l | 1.0–1.3 l |
How Much Does Progress 4 Weigh With Engine and Equipment?
To calculate. real In the rigging condition, use this formula:
Total weight = Body weight + Motor weight + Fuel weight (1 l ≈ 0.75 kg) + Battery weight + Equipment weight (anchor, pump, sonar, etc.) + Weight of passengers and cargo
Example of calculation for a typical fishing:
- 🛥️ Body: 145 kg
- 🔧 Motor. Mercury 15.: 36 kg
- ⛽ Fuel (20 litres): 15 kg
- 🔋 Battery: 12 kg
- ⚓ Equipment (anchor, paddles, pump): 20 kg
- 👨👨 Passengers (2 people in 80 kg) + cargo (30 kg): 190 kg
- Total: 418 kg (Exceeds the load capacity by 18 kg!)
⚠️ Attention: If the total weight exceeds 400 kg, the boat loses its buoyancy reserve. If water (for example, from a wave or rain) is hit, the risk of overturning grows exponentially. GIMS can be fined for overloading up to 2,000 rubles (Article 11.8.1 of the Administrative Code of the Russian Federation).
Make sure that the weight is evenly distributed (nose/feed)
Check the fastening of the motor and transcreant
Eliminate the transport of heavy loads on the nose
Use sealed containers for things
Check the water level in the drainage holes.
How to reduce the weight of a boat without losing functionality
If you "Progress 4." It was harder than expected, take advantage of these tips:
- 🔨 Replace the wooden seats Aluminum or plastic (savings up to 10 kg).
- ⛽ Use a smaller fuel tank. (e.g. 12 l instead of 20 l)
- 🧲 Remove unnecessary metal parts: extra braces, hooks, homemade holders.
- 📦 Keep your equipment in light bags Instead of heavy boxes.
Experienced owners also recommend:
- Paint the boat. powder-paint instead of liquid - this reduces weight by 3-5 kg due to the absence of dashing.
- Replace the standard
chunk-boxIt's a lightweight fiberglass model.
Before each trip, weigh the boat on a scale (for example, at a scrap metal reception point) to avoid hidden overload due to wet clothes or forgotten cargo.
Comparison with analogues: which is easier than “Progress 4”?
If weight "Progress 4." If you think it’s excessive, consider the alternatives:
| Model | Body weight (kg) | Max power (hp) | Advantages | Deficiencies |
|---|---|---|---|---|
| Kazanka-4M. | 140–160 | 30 | More stable on the wave | Harder, more expensive. |
| Ob-4. | 130–155 | 20 | Easy, cheaper. | Lower load capacity |
| "Swallow." | 110–125 | 15 | The easiest. | Thin body (1.5 mm) |
For comparison: PVC boats (e.g., Flagship 380.) weigh only 30-40 kg, but lose to aluminum models in strength and durability. minimumPay attention to this composite-boat (weighing 60 kg), but be prepared to pay 2-3 times more.
Frequent errors in estimating the weight of a boat
Many owners "Progress 4." They allow for these miscalculations:
- Ignoring the weight of the engine. Even a light one. Windy 8. adds 25 kg, and "Yamaha 30" - all 50 kg.
- Forget about the fuel. 20 liters of gasoline is +15 kg, which is often not taken into account.
- It doesn't take into account the weight of the passengers. The average fisherman with equipment weighs not 70 kg, but 90-100 kg.
- Don't check the drainage holes. 10 liters of water in the case = +10 kg of excess weight.
The result: the boat, which according to the passport should weigh 150 kg, in practice goes beyond 250 kg, and the owner wonders why it does not obey the steering wheel or "sucks" on the stern.
What happens if you exceed the load capacity?
When overloaded by 20-30%, the boat loses stability: even a small wave can cause a roll of 15-20 °, which is dangerous when turning sharply. In addition, the load on the transom increases - this leads to its deformation (especially in models with thin aluminum of 1.5-2 mm).
Conclusion: optimal weight for safety and comfort
The ideal weight for "Progress 4." In the condition of the gun, 180–220 kgIt allows you to:
- 🚗 It is easy to transport a boat on a trailer by car.
- 🌊 Keep stability on the wave to 0.5 m.
- ⛽ Save fuel (consumption does not exceed 1.5 l / 10 km).
- 👍 Comply with the requirements of GIMS without the risk of fines.
If your boat weighs more, review the equipment: perhaps you should give up the extra equipment or replace the heavy elements with lighter ones. pound-by-poundEspecially if you are planning long-distance hikes or fishing in large water bodies.
Regularly check the weight of the boat before getting on the water – this is the key to your safety and durability of the vessel.
FAQ: Frequent Questions About Weight "Progress 4"
Can I carry a Progress 4 on the roof of my car?
Theoretically, yes, but only if the weight of the boat does not exceed 70-80 kg (for example, without a motor and equipment), this requires special mounts and crossbars, as well as a speed limit of 80 km / h. In practice, most owners use a trailer - it is safer and more convenient.
How much does Progress 4 weigh with a Virg-30 engine?
Motor weight "Whirlwind 30." - about 45 kg. Together with a body (145 kg), fuel (15 kg) and minimum equipment (20 kg) the total weight will be 225–230 kgThis is close to the load limit, so it's recommended to reduce the weight of passengers or cargo.
What kind of trailer is needed for Progress 4?
A trailer with a load capacity of 300 kg (for example, "MISA 8107" or "Baby 4."Requirements: braking system (if total weight > 750 kg), reinforced spars and anti-corrosion coating. The cost of a new trailer - from 40 000 rubles.
Does the weight of the boat affect registration in the GIMS?
No, weight is not a criterion for registration, but the main thing is the power of the engine (over 10.88 hp requires registration) and the boat's passport. visual overloadIf the boat is sitting in the water.
Can you reduce the weight of the boat by drilling holes in the hull?
Absolutely not! Any arbitrary changes in design (including drilling) violate the tightness and strength. buoyancy If you want to lighten the boat, remove the equipment, not modify the hull.
