Soviet motorboat Progress 2 It is widely regarded as one of the most popular and reliable models in the history of domestic shipbuilding for water lovers. This aluminum boat, created in the back 60s, still plows the expanses of rivers and lakes, proving its exceptional survivability and practicality. Many owners still search for accurate data on its dimensions to plan transportation on the roof of a car or calculate the carrying capacity for fishing.
The question of what kind of Boat Progress 2 sizesIt's not just dry passport numbers, it's parameters that directly affect the stability of the vessel, its handling and comfort when on board a crew of three or four, and knowing the exact length, width and height of the board is essential for the proper selection of the engine and planning of the equipment.
In this article, we will discuss all the geometric parameters of the body, weigh the strengths and weaknesses of the design, and give practical advice on the operation of this legendary boat.
General specifications and history of the model
Motorboat Progress 2 The design was developed by the Kuibyshev Aviation Plant Korolev and began to be produced in the early 1960s as an improved version of the previous models of the series. The main goal of the engineers was to create an affordable, light and sufficiently spacious vessel for the mass tourist and angler, the design is made of aviation aluminum brand D16T, which provides high strength at relatively low weight, although it requires careful attention to corrosion.
Unlike later modifications, the second version of the Progress retained the classic contours with a blunt nose, which is typical of planing boats of that era. hull It's a flat-kiled shape that provides good stability in parking and low-speed driving, but it's the geometry of the bottom and the length-to-width ratio that determines how the boat will behave in the excitement and how efficiently it will get on plane.
⚠️ Attention: D16T aluminum, which is used to make the hull, is subject to electrochemical corrosion, and it is strongly recommended not to use a boat in salt water without special corrosion treatment, and to leave it on the water for a long time without hooding on shore.
The model's popularity is largely due to its maintainability and simplicity of design, and the lack of sophisticated electronics and hydraulics makes maintenance easy to understand, even for a beginner. It's important to note that over the years, the design has been minimally modified, so it's a very simple process. dimensions The main specifications remain the same for all copies produced in different years.
Detailed analysis of the dimensions of the body
For many owners, it is critical to know the exact linear dimensions, as the possibility of transporting a vessel on a standard car trailer or even on the roof of a passenger car using special fasteners depends on them. Progress 2 It belongs to the class of small craft, but its dimensions require careful planning of logistics.
The basic parameter is the length of the body, which is exactly 4,600 mm, which is the optimal size for accommodating three or four adults with a minimum set of equipment. thong-engine The total length of the vessel increases, which must be taken into account when parking or storing in a standard-sized garage.
The mid-spangout hull is 1,720 mm wide enough for a boat of this length to have a positive effect on initial stability. Passengers can navigate the sides with minimal risk of rolling, and anglers are comfortable catching fish or mounting tackle. However, the greater width increases sailing and water resistance, which should be considered when choosing engine power.
The bow height reaches 720 mm and the aft height is about 550 mm. This geometry provides good protection against splashes and wave swamps when moving against the wind. The bottom has a keeliness that smoothly decreases from nose to stern, ensuring course stability. The exact length of the waterline at full load is about 4200 mm.This affects the maximum speed and wave formation.
☑️ Checking the dimensions before buying a trailer
Table of the main technical specifications
For ease of comparison and planning of modernization, the following summary table with the main parameters is given: these data are data-sheet figures and may vary slightly for specific instances depending on the year of manufacture and condition of the case.
| Parameter | Meaning | Unit of measurement |
|---|---|---|
| Longest length | 4600 | mm |
| largest width | 1720 | mm |
| Height on midship | 650 | mm |
| Mass of the hull with equipment | 150 | kilogram |
| Load capacity | 400 | kilogram |
The weight of an empty hull of 150 kg is essential for manual carrying, so operating a boat usually involves having a slip, trailer or flat shore for descent. Load capacity 400 kg allows you to accommodate three people of medium build and about 50-70 kg of cargo, which is enough for a weekend trip or fishing.
And it's important to consider that the actual weight can vary, and over time, the boat becomes overgrown with algae, the holds accumulate water and dirt, and additional elements can be installed: anchor boxes, rundooks, reinforced cans. displacement It reduces the maximum speed.
Effect of weight on speed
With a 10 percent increase in the boat's total weight, the speed of planing drops by about 5 to 7 percent, and fuel consumption increases by 3 to 5 percent, so regular defouling of the bottom is critical to efficiency.
Capacity and passenger capacity
Constructively Progress 2 The boat is officially classified as having space for three people, but in practice owners often accommodate a fourth passenger, subject to safety and good weather regulations.
The interior space is designed to accommodate two transom seats (banks) and one longitudinal john or box in the bow, with a distance of about 1,600 mm between the sides in the midfield area, creating a spacious cockpit, and for fishing, this is an important advantage, allowing you to conveniently place gear and lifts.
- 🎣 For fishing: Ideal for 1-2 fishermen with a complete set of equipment, including a tent and outboard motor.
- ⛺ For tourism: Possible accommodation of two people with an overnight stay, but will require careful planning of the cargo and the use of inflatable mattresses.
- 👨👩👧👦 For the family: It is comfortable for parents and one child or three adults at short distances (up to 10-15 km).
Do not overload the boat, as this reduces the buoyancy reserve and freeboard height. When fully loaded, the board rises above the water by only 15-20 cm, which makes the boat vulnerable to side waves. Resilience In quiet water it is high, but in excitement the overloaded boat becomes dangerous.
⚠️ Warning: Passport load capacity (400 kg) leads to a sharp decrease in the height of the freeboard. If a wave hits an overloaded boat, the water may not be able to be drawn out, which creates a risk of overturning.
Recommended motors and speed specifications
The choice of powertrain depends on the desired speed and operating conditions. the manufacturer recommended the use of outboard motors with a capacity of 12 to 20 hp Modern four-stroke motors are often heavier than their two-stroke predecessors, so their choice must take into account the displacement. centre.
With a 10-12 hp engine, the boat confidently enters planing mode with one or two passengers. The speed is about 25-30 km / h. Installation of the engine with a capacity of 15-20 hp allows you to reach speeds up to 35-40 km / h, but requires careful management, since the body becomes more sensitive to yaw.
Standard motor installation is used turretWhen installing heavier engines (for example, powerful 4-strokes weighing more than 45 kg), it is recommended to strengthen the transom plate or use unloading transom wheels to avoid deformation of the aft part.
When installing a new motor, be sure to check the angle of the trim. For Progress 2, the optimal position is when the bottom when entering the plane is an angle of 3-5 degrees to the water surface.
Fuel consumption when driving on sleeving with full load is about 6-8 liters per hour for the engine 15 hp On economical mode (semiplane) consumption is reduced to 3-4 liters, which allows you to overcome long distances with one tank.
Transport and storage
Dimensions Progress 2 They make it possible to transport it on the roof of a passenger car, but it's challenging because of its length of 4.6 meters and weight. Most often, specialty trailers are used for transportation. When transporting it on the roof, you need to use elongated takeaways and reliable mounts, because the sailing of the cargo will be huge.
Keeping a boat indoors (a garage or a shed) is best by turning it upside down, which will prevent rainfall from entering and reduce the risk of corrosion. If storage outdoors is inevitable, use breathable awnings that let vapor through but retain water to avoid condensation under the tent.
- 🚗 On the roof: It takes at least 3-4 crosses and the help of a second person to lift.
- 🚜 On the trailer: The most convenient option, allowing you to quickly lower the boat into the water without unnecessary physical effort.
- 🏠 In the garage: It requires a space of at least 4.8 meters in length, taking into account the passageways, and it is recommended to hang on brackets to the wall to save space.
Winter storage should be in a dry place. Aluminum is not afraid of frost, but rubber seals and wooden elements (if any) can suffer from changes in temperature and humidity. It is recommended to lubricate the moving parts and close holes in the case from rodents.
The best way to transport Progress 2 is to use a lightweight single-axle trailer, which preserves the body of the car and makes it easier to launch.
Frequently Asked Questions (FAQ)
Can I install a 25 hp engine on Progress 2?
Technically, it can be installed because the transom will withstand, but it is not recommended by the manufacturer. Power over 20 hp can lead to excessive burrowing of the nose in the wave, reduced handling and increased risk of damage to the hull at high speed.
What is the real weight of a Progress 2 boat without an engine?
Passport weight is 150 kg, but in reality, taking into account the accumulated soil, paint, installed boxes and equipment, the weight often reaches 160-170 kg.
Do I need to paint the Aluminum case of Progress?
Aluminum itself forms an oxide film that protects against corrosion, and does not need to be painted. However, painting with epoxy or polyurethane paints improves the appearance, reduces algae fouling and facilitates washing. The main thing is to properly prepare the surface (clean and degrease) before applying the soil.
Will Progress 2 fit in a standard garage?
A standard garage is about 6 meters long and 3-3.5 meters wide. A boat is 4.6 meters long and allows it to be placed inside, leaving room for passage. However, a width of 1.72 meters can be critical if the garage has shelves or tools on the sides. In such cases, the boat is often placed at an angle or removed one side (if the design allows, which is not typical for Progress) or used ceiling storage.
