Soviet-made aluminum boats, and in particular the Progress 2 model, remain popular among water-engineers, due to their reliability, maintainability and affordable cost on the secondary market. geometrical products.
Knowing the exact dimensions is not only necessary for estimating capacity, but also for planning transportation, storage in the garage or under the canopy, and for selecting the appropriate outboard motor. Often in documentation or when sold from hand, data can be rounded, leading to unpleasant surprises when trying on a trailer or calculating a load.
In this article, we will analyze in detail all the nuances of the design, give the exact drawing dimensions and discuss how the dimensions affect the driving performance of this legendary Kazanka. You will learn how to measure your specimen and what to pay special attention to when assessing the condition of contours.
General specifications and history of the model
Boat. Progress 2 It was developed by Kazan Gorbunov Aviation Plant as an evolution of the first Progress model, the main difference being the modified shape of the bow and the reinforced hull set, which allowed to increase seaworthiness. The design is made of the AMg5M aviation alloy, which is perfectly welded and resistant to corrosion in fresh water.
The body has flat-wheeled contours with splash-blowers, which provides a good germination on the wave when properly loaded, and unlike earlier versions, it has increased the breakdown of the sides in the nose, which has a positive effect on stability. Overall dimensions They remained within the standards for boats of this class, which allowed them to be transported on the roof of a passenger car, although the weight already required the use of trailers.
⚠️ Note: When buying a used boat Progress 2 be sure to check the presence of the manufacturer's stamp and the correspondence of the actual dimensions to the data-sheet figures. Often cases when the boats were assembled artisanal or after serious accidents, which changes their geometry.
Designed as a versatile vessel for fishing and recreation on large bodies of water, the model allows the installation of outboard motors up to 25 hp, although modern owners often put more powerful units, which requires caution due to the height restrictions of the transom.
Detailed dimensions of the hull and deck
To correctly calculate the deck area and understand how many people will comfortably fit in the cockpit, you need to operate with accurate numbers. waterline The total length of the water varies, which is important to consider when calculating the speed and resistance of the water.
The mid-spangout width determines the stability of the boat. In Progress 2, this parameter is optimal for calm water and a little excitement, but when fully loaded, the width may not seem enough due to high sides. The height of the board on the midfield allows you to feel confident on the water, but increases sailing.
- 📏 The hull is 4,690 mm long, which is the standard size for 4-5 local aluminum boats.
- 📏 The width of the maximum size (without zygomatic linings) is 1720 mm, which allows you to stand steadily in full growth.
- 📏 The height of the side on the midfield reaches 720 mm, providing protection against splashes even when moving against the wave.
- 📏 The bottom angle of the transom is about 10 degrees, which is a trade-off between speed and stability.
It is important to note that the actual measurements on older boats can vary by 1-2 cm due to deformations during operation or impacts on the bottom. If you plan to make an awning or case, always base the actual measurements of your specimen, not reference data.
Effect of nose shape on dimensions
The forward part of Progress 2 has a pronounced cheekbones that visually and actually increase the width in the bow quarter of the body, which should be taken into account when making a transport lounge trailer, so that the sides do not rely only on the keel.
Parameters of transom and outboard motor
The trans is the maximum load zone, so its size and condition require special attention. It depends on the height of the transrans whether the boat will plane with the chosen engine. prairieBut its height is limited by the design of the feed can.
The standard height of the transom for an outboard motor is 380 mm (15 inches), which corresponds to the current standards at the time of release. However, when installing modern motors with a long leg (20 inches), often require the manufacture of a superstick or the use of a stretcher, as the regular stock may not be enough for the optimal angle of the trim.
| Parameter | Value (mm) | Admission/Note |
|---|---|---|
| Transnz height (standard) | 380 | For short leg motors |
| Transnz width (working) | 410 | Distance between sides |
| Thickness of the transmutation board | 25-30 | Along with the overlays |
| Max, engine power. | - | up to 25 hp (passport) |
When installing the engine, it is important to observe the alignment of the lower unit with the plane of the transom, distortions can lead to yawing of the boat on the course and increased fuel consumption. bracket motor attachments, which may weaken over time.
When you set the motor to Progress 2, use a dynamometer key to tighten the rods. Aluminum is softer than steel, and the pulling can damage the transom plate, and the slack will cause vibrations and noise.
Capacity and load capacity
One of the key specifications for anglers is the payload and payload capacity of the Progress 2, which is 400 kg, which formally allows for 4-5 people on board, but real-world operation makes its own adjustments to these figures.
For safe planing with a minimum power engine (about 10-12 hp), the crew should not exceed 2-3 people with a minimum supply of equipment. At full load (4 people + equipment), the boat confidently keeps on the water, but goes to planing only with a powerful engine (20+ hp) and the correct weighting.
- ⚓ Passenger capacity on passport: 4 persons.
- ⚓ Full capacity: 400 kg (including weight of people, motor and equipment).
- ⚓ Useful deck area: about 5.5 m2, allowing free movement.
The distribution of the cargo should be such that the bow of the boat does not burrow into the wave. The main weight (battery, anchor, heavy bags) is better placed in the midfield or closer to the stern, but not overloading the transom, so as not to change the differentiator on the stern.
⚠️ Warning: Exceeding the rated carrying capacity on aluminum boats with a flat bottom in the bow can lead to a dangerous phenomenon of “cobra” (a sharp throw of the nose up) or, conversely, to burrowing the nose into the oncoming wave.
Boat weight and transportation issues
The weight of the body is a critical parameter for choosing a trailer and a tractor car. The design weight of Progress 2 without the motor and equipment is approximately 140-150 kg. This is enough for manual loading on the roof of the car, so the presence of a trader is almost mandatory.
When calculating the total mass for category B, the weight of the trailer itself (about 100-120 kg), the weight of the engine (30-50 kg), the fuel (about 20 kg) and the crew must be taken into account. The total mass can easily exceed 750 kg, which requires careful attention to the rules of the road and the technical condition of the trailer braking system.
☑️ Pre-shipment checks
Boat dimensions in the transport position (on the trailer) meet the standard standards: width does not exceed 2.2 meters (including the wheels of the trailer), height is usually up to 2 meters.
Drawings and size modifications
There are many modifications and factory changes made to the design of Progress in different years of release, for example, later versions may have reinforced hinge bars or a modified shape of the forehead, so relying only on general data from the Internet can be wrong.
If you are planning a serious tuningFor example, if you install a fiberglass deck or redesign a cockpit for specific fishing tasks, you will need accurate drawings, which can be found in specialized magazines (boats and yachts, motors for the relevant years) or remove yourself using laser level and roulette.
Pay special attention to the curvature of the sides when you take the size, aluminum is plastic, and over decades of use, the shape of the cross section can change, use a flexible line or a long ruler to check the planeness of the sides in the area of installation of consoles and cans.
Accurate knowledge of the dimensions of Progress 2 is necessary not only for purchase, but also for safe operation, stability calculation and selection of compatible equipment.
FAQ: Frequently asked questions
Can I install a 30 hp engine on Progress 2?
Technically, it is possible to establish, because the transom is able to withstand, but this exceeds passport restrictions. This requires registration of changes in the GIMS and can be dangerous because of the risk of loss of stability at high speeds. It is recommended not to exceed 25 hp.
What is the real weight of the Progress 2 boat with attachments?
Weight empty hull about 145 kg With installed banks, anchor box, safety elements and standard equipment weight ready to descent boat (without engine and fuel) is about 160-165 kg.
Will Progress 2 fit into a standard garage?
The 4.69 meter length requires a garage with a minimum of 5.5-6 meters in length for comfortable accommodation with the possibility of bypassing. 1.72 meter width allows you to put a boat along the wall, leaving a passageway. The height of the board is 0.72 m allows you to use the space inside the boat to store things if it is upside down.
Do I need to register Progress 2 in GIMS?
Yes, the weight of the curb boat (145 kg) plus the weight of the engine (even the lightest, 10 kg) exceeds 200 kg. Therefore, registration is mandatory.
