When choosing a reliable boat for fishing or hunting, many drivers pay attention to the time-tested Soviet classics. Progress-2However, when buying a used copy or preparing for transportation on a trailer, a critical question arises: what is the real width of the boat Progress 2 and how does it correspond to the values stated in the passport.
Many owners are faced with the fact that actual measurements may differ from tabular data due to the design and age of the vessel. Overall width Not only does it affect water stability, but it also affects the ability to pass through locks, ease of loading on the roof of the car and compliance with GIMS requirements. In this article, we will discuss all aspects of the body size in detail.
Understanding the exact dimensions is necessary to correctly calculate the load capacity and select the appropriate one. boat-engineA misestimation of width can lead to stability problems or even high wind emergencies. Let's find out which numbers are reference numbers and which can vary depending on the modification.
data-sheet figures and real measurements of the body
According to the factory documentation, which was developed in the era of rigid GOST, the width of the body on the mid-spangout (the widest part) was strictly regulated. Progress-2 This parameter is 1360 mm. However, this value refers to the widest point of the contours of the shell, excluding the hinges and other protruding elements.
In practice, if you measure a particular instance, you can get values that vary by a few centimeters in the larger or smaller side. aluminum-alloy The D16T, which is the body, may deform slightly over time when hitting the ground or when wintering is incorrect, and the measurement method, whether on the outer edges of the side or on the interior, also plays a role.
⚠️ Note: When measuring the width for transportation on the roof of the car, be sure to take into account the protrusion of rubber bands and pendants, which can add to the passport width another 30-40 mm on each side.
It's important to distinguish between cheekbone width and flatburrow width. overall width For transportation, you need to focus on the upper edge of the side, and the inner width, useful for seating passengers, will be much smaller, depending on the thickness of the metal used and the presence of internal cans.
Design features affecting the dimensions
Boat design Progress-2 This involves the use of riveted junctions of sheets of skin, where the junctions of sheets, especially in the zygomatic gyres, form thickenings. These structural elements, although insignificant, affect the overall geometry and the overall geometry of the sheets. stability The riveting was done in two rows, which added strength, but also millimeters to the outer perimeter.
The special attention should be paid to the transom part, the width of the transom in this model is less than the width of the midwives, which is typical for sliding shells with a pointed nose, which provides better sensibility per wave, but reduces the area of useful space in the stern. electric motors or light gasoline units, this creates certain restrictions on the placement of gear.
Many owners are upgrading, installing additional setup Installing additional stringers or reinforcing the bottom with sheets of metal can also visually and physically change the perception of the width of the interior space, although the outer dimensions will remain unchanged.
Comparison with modern analogues and modifications
To understand whether it is a lot or a little – 1360 mm, it is worth comparing. Progress-2 The Soviet School of Engineering relied on versatility, so the dimensions were often compromised between capacity and transportability.
Below is a table showing the difference in size between Progress 2 and its closest relatives and competitors:
| Model boat | Body width (mm) | Years of issue | Materials |
|---|---|---|---|
| Progress-2 | 1360 | 1964–1972 | Aluminum D16T |
| Progress 2M | 1360 | 1972–1977 | Aluminum D16T |
| Crimea-2 | 1550 | 1968–1975 | Aluminum D16T |
| Ob-2. | 1480 | 1967–1974 | Aluminum D16T |
As you can see from the comparison, Progress-2 It's one of the narrowest boats in its class, and it was dictated by the need to provide high speed with low-power engines like the Winds or Neptune. CrimeaThey had better stability, but required more powerful engines to get on plane.
Modern aluminum boats are often 1,500 mm or more wide, as production technology and available engine power have changed the approach to design. Progress It is still valued for excellent driving performance on a small wave and the ability to be towed by powerful cars without exceeding the dimensions.
The impact of width on seaworthiness and sustainability
The width of the hull directly determines the initial stability of the vessel. Progress-2 It makes it roller in the parking lot or when driving slowly, and passengers should move carefully along the cockpit to avoid dangerous traffic. rollwhich may cause water to be scooped up by splashes.
On the other hand, when going planing, the narrow shape contributes to better stability, the boat is less prowling on the wave, it is easier to control one person, and for single fishing or cruising together, this width is optimal, providing a balance between speed and safety.
Any interference with the design, such as the installation of wide inflatable tubes-likbez, can radically change the behavior of the vessel on the water, making it unpredictable during sharp maneuvers.
Transportation and storage: practical aspects
The size issue is particularly acute for car owners, with a width of 1360 mm allowing the boat to be placed on the roof of most passenger cars, including classic Zhiguli or modern sedans, but the mounting must take into account the protrusions and properly distribute the load.
When stored in a garage or barn, a narrow boat takes up minimal space, can be placed vertically on the stern or hung from the ceiling, saving usable space, a significant advantage over wider models that require dedicated floor space or a dedicated trailer.
☑️ Pre-shipment checks
If you plan to transport a boat assembled over long distances, it is recommended to measure the width of the trailer body or the distance between the wheel arches of the car in advance. Gap. shall be sufficient to avoid friction and damage to the paintwork or metal on the suspension elements.
Tuning and changing the useful width of the cockpit
Many enthusiasts don't tolerate the crampedness of a standard cockpit and resort to tuning, installing removable or stationary cans of a different design, transferring the runduks to the sides allows you to win several centimeters of useful space. strength The body should not suffer when drilling new holes.
A popular solution is to install soft pads on the piers, which not only protects the side from damage, but also visually and tactilely expands the space, making the landing more comfortable. Some craftsmen install additional planshares, increasing the width of the upper part of the board for ease of attachment of the gear.
It is important not to overweight the expansion, excessive weighting of the sides or shifting the center of gravity upwards can make a narrow boat dangerous to operation, all improvements must be balanced and comply with the safety rules on water bodies.
Legal aspects and registration in GIMS
When registering a small vessel in the GIMS, the width is indicated in the boat's ticket. Progress-2 If the boat has undergone a major alteration that has changed its dimensions (e.g., bot build-up), this may require changes in documents or even recategorization of the vessel.
Under current regulations, small boats weighing up to 200 kg and up to 8 kW (inclusive) do not require registration, but narrow boats are often equipped with more powerful engines, which automatically requires the owner to carry documents. Dimensions The vessels also affect the complexity category of the waterway over which traffic is allowed.
⚠️ Warning: When buying a boat from hand, be sure to check the number on the transom with the data on the boat's ticket. Lack of documents or discrepancies in numbers make registration impossible, and operation illegal.
In the event of loss of documents, data on width and other specifications can be recovered through archives or specialized forums where scans of factory passports are stored, and accurate knowledge of size will help avoid problems when communicating with inspectors on the water.
Frequently Asked Questions (FAQ)
Can I increase the width of Progress 2 by myself?
In theory, you can weld or rivet additional sheets, but this will violate the design stability and strength of the hull, which makes the boat unsuitable for safe operation and registration.
Will Progress 2 fit into the trunk of the station wagon?
At a width of 1360 mm, the boat will not fit into the standard trunk across. Longitudinally it can only be placed in a very long wagon or hatchback with folded seats, but the overhang will be too large and dangerous.
What is the inner width of the cockpit?
The inner width varies from 1100 to 1200 mm in the widest part, depending on the presence of internal hazelnuts and the thickness of the skin.
Does the width affect the speed of the boat?
Yes, the narrow body has less water resistance, which allows you to develop a higher speed at the same engine power compared to the wide counterparts.
