When choosing the first or next aluminum boat for fishing and resting on the water, one of the decisive factors is the knowledge of the exact dimensions of the vessel. boatThe silk-powered version, produced at the Progress plant in Kuibyshev (now Samara), has been the benchmark of reliability and availability among small vessels for several decades, but despite the recognizable name, the modifications of this series differ significantly in their physical parameters, which directly affects the possibility of transporting them on the roof of a car or storing them in a standard garage.
In this detailed review, we will discuss boat-size For all current models, from compact versions to full-fledged troll boats, understanding the difference between the length of the hull, the overall length with the tanning board and the internal usable area of the cockpit will help you avoid mistakes when buying, and we will also touch on weight issues, which are critical when choosing a motor, and look at how the plant standards have changed over the years of production.
Knowing the exact numbers is not only necessary for logistics, but also for calculating the stability and maximum power of the engine. The wrong motor can overload the transom, and too heavy anchor can shift the center of gravity. Next, we will analyze the technical specifications in detail, based on factory data and practical experience of water engines.
Evolution of sizes: from Progress 2 to Progress M
The Progress line was a journey from simple rowing boats to high-speed planing boats, each new model incorporates the experience of the previous ones, which reflected the change in the geometry of the hull. While the earlier versions were designed with a focus on maximum capacity at a minimum length, more modern models received contours that contribute to better wave ascent and planing.
Special attention should be paid to the differences between the modifications "2" and "4", as they are most often found in the secondary market. Boat Progress-2 The Quartet was positioned as a more compact solution for calm water bodies, while the Quartet became a full-fledged working tool for large rivers and reservoirs, and the increase in length and width in new models has significantly improved seaworthiness.
It is important to note that the manufacturer may have made minor changes in the process at different times, sometimes resulting in minimal discrepancies in actual measurements. dimensions Understanding these nuances will help you to more accurately assess the condition of a particular boat when buying.
- 🚤 Progress 2: The basic model, focused on efficiency and ease of operation at low speeds.
- 🚤 Progress 4: An enlarged version with a sharper nose, designed to install engines up to 30 hp.
- 🚤 Progress-M: Upgraded model with modified transom geometry and reinforced body set.
Table of model comparative specifications
To make a visual comparison of the different modifications, the best way to use a composite table is to show the basic linear dimensions that determine the vessel's operational capabilities. Notice the difference between the length of the hull and the full length, which takes into account the protrusions of the transom board.
Weight in running order is also a critical parameter: the aluminum-magnesium alloy that is made of. boatIt offers excellent corrosion resistance, but it adds mass compared to PVC analogs, but it also adds strength and durability to the structure.
| Parameter | Progress-2 | Progress-4 | Progress-M |
|---|---|---|---|
| Full length, m | 4.00 | 4.65 | 4.55 |
| Maximum width, m | 1.38 | 1.55 | 1.60 |
| Mid-level height, m | 0.43 | 0.50 | 0.52 |
| Weight of shell with equipment, kg | 140 | 190 | 165 |
Analyzing the data from the table, it can be seen that Progress-MThe squirrel, although shorter than the four, is wider, making the boat more stable in parking and throwing, which is highly valued by fishermen, while the four are better off in wave performance by making the rounds more elongated.
The choice between length and width is a trade-off between driving performance (length) and stability (width).
Detailed analysis of the Progress-2 model
Model Progress-2 It has long been the most massive boat in the USSR and the former Soviet Union, and its size allows you to transport the boat in the upper trunk of a passenger car without any problems, which was and remains an important advantage for many owners, a length of 4 meters is considered the “golden mean” for small bodies of water.
The interior of the cockpit is organized reasonably for this size, and there are hand-helds for storing things that also serve as seats. transom board It has a standard neckline for lower unit, which allows you to install most low-power outboard motors.
⚠️ Attention: When installing the engine on Progress-2, strictly monitor the height of the transom. Exceeding the engine power above 12-15 hp can lead to nose burrowing and loss of controllability, since the flat contours of the bottom are not designed for high speeds.
The load capacity of the model allows you to comfortably accommodate two or three people with a full set of equipment. passport capacity And the real safe load is different, especially when you're out in open water in windy weather, and you have to keep the coast in sight.
Features of welded seams Progress-2
Early models could have been less tidy than modern models, and when buying a used boat, carefully examine the angles and joints of the sheets for microcracks that can become hotbeds of corrosion.
specifications and dimensions Progress-4
Progress-4 The boat, which is a much more serious vessel that can be classified as a boat, with its length of 4.65 meters and width of 1.55 meters, has significantly improved seaworthiness, and is more confident in its wave and less prone to rolling, making it a preferred boat for larger reservoirs.
The hull design provides a more powerful set, which increased the total weight to 190 kg, a significant increase compared to the previous model, which must be considered when planning transportation. aluminum-boat Often a trailer is required, as it will be difficult to put it on the roof alone.
- 📏 The length of the CWL: It is about 4.2 meters, which provides good planing.
- 📏 Transcent height: 380 mm, which allows you to install motors with a long leg.
- 📏 Passenger capacity: Up to 4 people, but more comfortable two or three.
The engine compartment and cockpit are separated by a bulkhead, which increases safety and unsinkability, and the bow often organizes boxes for anchor and equipment. Load capacity 400 kg allows you to take on board a solid supply of fuel and equipment for multi-day exits.
When buying Progress-4, be sure to check the condition of the floorboards (floors), in older models they could rot or deform, creating a danger when cruising on the cockpit.
Features of the design Progress-M
Modifications Progress-M The main change was the recycling of the bow and transom, and the hull was optimized: the length was reduced to 4.55 m, but the width increased to 1.6 m, which had a positive impact on stability.
In construction (widely used) aluminum-magnesium alloyIt's lighter and stronger than traditional duraluminium, and it's reduced the weight of the hull to 165 kg, while maintaining its strength, and it's lighter on the go and more fuel efficient with the same engines.
The Model M's trawler is reinforced and has a special shape to prevent water from being sucked for an outboard motor, which is especially true when driving against a wave or at high speeds, and the ergonomics of the seats and the knobs have also been improved.
⚠️ Attention: Despite the improved corrosion resistance of the alloy, electrochemical corrosion is still possible when in contact with other metals (such as steel bolts).
For Progress-M It's very powerful, up to 30-40 hp, which makes the boat a speedboat, but even then it's important to follow the loading rules and not exceed the recommended angles of the differential.

Transportation and storage: practical advice
Dimensions of boats of the series Progress They dictate certain conditions of transportation. Progress-2 You can still carry on the roof of the "classic" or station wagon (in the presence of a strong trunk), then for the "four" and "M" modifications you will need either a very long car, or, more reasonably, a boat trailer.
When stored in winter, it is important to ensure that the internal volume is ventilated. Aluminum does not rust like steel, but condensate accumulated in an enclosed space can lead to oxidation and "white fluffy" corrosion. The boat is better stored upside down or under a canopy.
If you plan to keep a boat in your garage, measure the interior dimensions of the space beforehand. 1.55-1.60 meters wide requires a garage of standard size or larger if there are shelves or racks inside. 4.5 meters long also requires free space to pass.
- 🚗 Roof: It is only acceptable for Progress-2, requires reinforced arcs and reliable fastenings.
- 🚛 Trailer: The best option for all models, provides safety during transportation.
- 🏠 Garage: Requires consideration of the width of the gate and the interior space for maintenance.
How to Prepare for Winter
Pour all the water left over, remove the seats and dried knobs, lubricate the hinges and locks with silicone lubrication. Cover the boat with a breathable awning to avoid condensation under cover.
The influence of sizes on motor choice
The size and weight of the boat directly affect the choice of the boat. outboardFor Progress-2 with its 140 kg of weight and flat bottom will be the ideal engine in the range of 9.9-15 hp Attempting to put a 20-strong can lead to the fact that the boat will “goat” (jump nose), which is unsafe.
Progress-4 and Progress-M With their increased length and altered geometry, the bottoms require more powerful thrust to go into planing under full load, where the optimal range would be 15 to 30 hp engines. It is also important to consider the length of the lower unit: these models usually require a long leg (L) to avoid cavitation.
When choosing a motor, also look at the weight of the engine itself. A heavy four-stroke motor on the transom of a small boat can shift the center of gravity too far back, which requires constant finning or carrying the load to the nose.
⚠️ Attention: Never exceed the maximum recommended engine power specified in the boat’s passport. This is not only dangerous, but can also lead to the destruction of the translatum and the loss of warranty (if it is still relevant).
A properly selected boat-motor bundle will ensure not only safety, but also fuel economy, as well as comfortable handling of the vessel in various weather conditions.
For planing Progress-4 with two passengers and cargo, the minimum required engine power is about 15-18 hp Less power will allow only the displacement mode.
Frequently Asked Questions (FAQ)
What is the maximum load capacity of the Progress-4 boat?
The passenger capacity of the Progress-4 is 400 kg, which includes the weight of passengers, motor, fuel, equipment and anchor equipment, and exceeding this limit is dangerous for the stability of the vessel.
Can I weld a crack on the Progress aluminum boat on my own?
Theoretically, it can, but it requires special equipment (argono-arc welding) and aluminium welding skills. Normal electric welding is not suitable. For quality repairs, you should contact a specialized workshop.
What is the minimum garage size required for Progress-M?
Given the length of 4.55 m and width of 1.6 m, the minimum garage size should be about 5x3 meters for comfortable placement of the boat on the trailer and the possibility of around it for maintenance.
Do the sizes of the progress vary from year to year?
The base dimensions (length, width) remained unchanged throughout the production model, but the thickness of the metal, welding quality and equipment could vary depending on the year and the batch.
Do I need to register the boat Progress in GIMS?
Yes, all Progress boats are subject to mandatory registration with GIMS, as their weight exceeds 200 kg (complete with an engine) or length is more than 3 meters, and they are also intended for use with an engine.
