The Soviet legacy of water transport still arouses keen interest among fishermen and hunters. Progress 2M The duraluminum boat, which has become a symbol of reliability and accessibility, despite the model’s venerable age, continues to ply the expanses of Russian rivers and lakes, successfully competing with modern counterparts made of PVC and composite materials.
You should know that this model represents a deep modernization of previous versions of Progress, and engineers at the time tried to eliminate most of the design flaws by making the boat more stable and comfortable to accommodate passengers, and it was the balance between load capacity and seaworthiness that made this project so popular in the 70s of the last century.
Today we will examine all the nuances of operation, technical features and tuning capabilities of this boat, you will learn why many still prefer heavy metal to light inflatable counterparts, and whether to buy such a boat these days.
History of creation and design features
Development Progress 2M The design was based on earlier models that had some critical flaws, and the main requirement for the new modification was to improve safety and driving performance, and the designers changed the contours of the hull to make them smoother, which allowed for reduced water resistance and improved handling on turbulence.
The main difference was the shape of the bottom and zygomatic lines. Resilience The vessel was significantly upgraded, allowing passengers to be safely accommodated not only on banks but also on boards (although the latter is not recommended), the body was made of D16 duraluminium alloy, which is highly durable, but is susceptible to corrosion when in contact with salt water or galvanic processes.
⚠️ Note: During the operation of the boat from duralumin, contact with copper-containing antifouling paints is strictly prohibited, as this causes instant electrochemical corrosion of the metal.
The design provided for the existence of timberIt was a mounting mount that protected the sides from impact and served as a stop when mooring. Unlike earlier versions, the 2M had improved the mounting positions for the outboard motor, and the Tran became more reliable and its height was consistent with the requirements of most common engines of the time.
The strength gain system deserves special attention. spangout And stringers that form a rigid frame, which allows the boat to withstand severe impact loads, such as when you go to unequipped shore or when you encounter a drowner, which often happens during fishing.
Technical specifications and dimensions
To understand the capabilities of the vessel, you need to consider its parameters in detail. Progress 2M The size of the vessel allows it to be carried on the top trunk of a passenger car, although the weight of the hull will require physical training or the help of partners.
Below is a table of the main specifications that will help you assess the suitability of the boat to your requirements:
| Parameter | Meaning |
|---|---|
| Longest length | 4550 mm |
| largest width | 1600 mm |
| Height on midship | 650 mm |
| Load capacity | 400 kg |
| Weight of the hull without equipment | 135 kg |
The vessel has a capacity of up to 4 people, but the most comfortable on board feel two adult fishermen with a full set of equipment. Passport capacity The engine is limited to 12 hp, but experienced water-engineers often put engines up to 15-18 hp, which allows you to reach speeds up to 30-35 km / h.
It is important to note that the weight of 135 kg is a significant disadvantage during transportation. Descent of the boat on the water and ashore require a good car trailer or slip. It is almost impossible to cope with this task alone, especially on slippery ground.
Navigability and manageability
On the water. Progress 2M The high side provides excellent spray protection, which is critical for catching in open water in windy weather, and the vessel keeps the wave well without burrowing its nose, thanks to a special shaped forehead.
The handling depends on the location of the cargo. differentiation The boat is smooth, without yaw, but there's a caveat: when you're running full gas with one person on board, you can dolphinize, or rhythmic surges in the nose, and to avoid that, you need to move the load closer to the stern or use transom plates.
To improve the performance of the plane, install a hydraulic lift or adjustable transom plates on the transom. This will help to optimally set the angle of the trim.
On oars, the boat is heavy due to its heavy weight and wide stern, but it is quite manageable. The paddle paddles allow for standard oars. For long-distance crossings under oars, it is better to use light wooden or composite oars, since regular aluminum oars can be too heavy.
⚠️ Attention: When driving for an outboard motor, monitor the water level in the cockpit. The presence of water at the bottom dramatically reduces stability and can lead to a tipping over when passengers move sharply.
Internal arrangements and configuration
The interior of the boat was designed to be as functional as possible, with two removable seats (banks) fitted in three positions: forward, middle and stern, allowing for flexible adjustments to the vessel's centre depending on the number of passengers.
The boat floor is flat, which is convenient for placing boxes with gear, but requires the use of mats for comfort and protection from slipping. forepic - a sealed compartment that serves to store things and ensures the unsinkability of the boat in the event of a rollover.
For fixing equipment along the sides are passed flat-barLater versions have built-in gas tank drawers under the front seats, which have improved safety and ergonomics.
☑️ Check before buying a used boat
Many owners immediately after purchase think about upgrading the interior space, installing soft linings on the banks, installing hazelnuts and mounting the sonar greatly improve the comfort of operation.
Typical problems and their solution
Despite its reliability, age takes its toll. corrosionIf the boat is not stored properly or has been damaged, fistulas may appear on the bottom, repairs may be possible with argon welding or patching on epoxy compounds, but it is better to prevent problems.
Another common problem is loosening rivet joints, and the vibration from the motor over time unwinds the rivet, which leads to leakage, which requires bulkheading or additional sealing pads, and often the paintwork inside the body suffers.
To restore the protective layer, it is recommended to use special epoxy soils for aluminum. Colouring Not only improves the appearance, but also protects the metal from the aggressive effects of water and ultraviolet light.
How to check the boat for hidden leaks?
Pour water into the boat through a hose, spreading it evenly over the bottom. Leave it for 30-60 minutes. If the water starts to go away faster than it evaporates, inspect the seams. An alternative method is to flip the boat over and spill the seams with water outside, watching the drops appear inside.
Tuning and modernization Progress 2M
Progress owners are known for their creative approach to improving boats, and the most popular type of tuning is the installation of the boat. consoleThis allows the dashboard, steering and navigation devices to be placed in a protected location, freeing up space in the cockpit.
Windshields and awnings are also popular, and the transformer transforms an open boat into a full-fledged microboat that allows you to spend the night on the water or hide from the rain, and some craftsmen even install small, fiberglass cabins.
Modernization often involves the chassis. hydrofoil The engine's lower unit helps to get out faster and save fuel, and increasing the length of the tuber or installing remote control makes operation more convenient.
Competent tuning can extend the life of an old boat for a decade, turning it into a comfortable vessel, not inferior to modern models.
FAQ: Frequently asked questions
What is the maximum weight of the engine to be put on the Progress 2M?
Officially, the passport power is limited to 12 hp (about 40 kg), but the reinforced transom allows you to install engines up to 15-18 hp (about 45-50 kg), exceeding this weight can lead to deformation of the transom and reduced safety.
Do I need to paint the bottom of Progress 2M?
Yes, paint is desirable. Factory paint wears off over time. Regularly refurbishing the enamel layer or using kuzbasslak (as a temporary solution) protects the metal from corrosion and algae fouling.
Can I walk on Progress 2M in the sea surf?
The boat is certified B (inland waters) and partly C (coastal waters) and can only go out in quiet weather and near the shore, the high side sails in the wind, and the flat bottom is not designed for serious sea waves.
Where to find the plans for the repair of Progress 2M?
Original drawings can be found in the archives of Boats and Yachts magazines from the 70s or in specialized powerboating forums, but for repairs, more often than not, visual inspection and understanding of the design of similar dural boats are enough.
