Soviet shipbuilding gave water-motorcraft many reliable boats, but few models cause as much nostalgia and respect as the model. Progress 2This boat has become a symbol of an era when quality and durability were put before marketing ploys. Today, in the age of composites and inflatable PVC membranes, the aluminum classics are undergoing a renaissance, and enthusiasts are eager to buy up preserved specimens for restoration.
The uniqueness of the project was a successful combination of simplicity of contours, high strength of the case and the availability of materials. duraluminiumThe rods and plating made it possible for the boat to maintain low weight while having tremendous impact strength, which is why many boats built in the 70s still ply the vastness of rivers and lakes, requiring only minimal maintenance.
Owners should immediately be aware that the operation Progress 2 Despite its strength, the D16T alloy is susceptible to electrochemical corrosion when it comes into contact with other metals in salt water, and requires high-quality paintwork. A competent approach to maintenance will allow your vessel to last for several decades.
History of creation and design features
Development Progress 2 The project was conducted at the Nikolaevsky shipyard "Ocean" in the early 1960s, and the designers were tasked with creating a mass boat, surpassing the seaworthiness of the popular "Kazanki" and "Obi". high-bondThis provided excellent germination on the wave and reduced shock overload during the course.
The body is designed with riveted-weld technology, meaning that the sheets of skin are welded together, and the set (spangouts, stringers) is riveted or welded depending on the year of manufacture, and this hybrid technology made it easier to produce and tighten the seams, which was critical for water safety.
Interesting fact about production
The early Progress 2 series used hand riveting, making each boat unique, and the seams were often smeared with a meerka smear, which hardened over time, providing additional tightness but making repairs more difficult.
One of the key design features was forepic The bow, which was completely sealed and served not only as a buoyancy but also as a storage rod, was designed to accommodate an outboard motor of up to 30 hp, which was a pretty impressive figure at the time.
Technical specifications and dimensions
To understand operational capabilities Progress 2 It's important to look at the data-sheet figures in detail, and these parameters have a direct impact on engine choice, load capacity and vessel behavior on the water.
| Parameter | Meaning |
|---|---|
| Full length | 4,000 mm |
| maximum width | 1500 mm |
| Height on midship | 500 mm |
| Mass of the hull with equipment | 140 kg |
| Load capacity | 400 kg |
The boat’s capacity is 4 people, but at full load (400 kg) the draft increases significantly, which requires caution in choppy conditions. Seaworthiness It is estimated at 0.75 meters of wave height, which allows you to feel confident in large reservoirs and in the coastal zone of the seas.
It is important to note that the weight of 140 kg makes the boat heavy enough to be transported on the roof of a passenger car without a special reinforced trunk. Progress 2 They are transported by trailer, which is the safest and most convenient way of delivery to water.
When measuring the dimensions for the trailer, always add 10-15 cm to the length and width to account for protruding elements (tiller, transom plate, keelson) to avoid problems when loading.
Body materials and corrosion protection
Main material for Progress 2 This is an alloy of aluminum with copper, magnesium and manganese, which, after heat treatment, acquires high strength, but this material has an Achilles heel, low corrosion resistance in aggressive environments without protection.
Unlike pure aluminum, dural does not form such a dense oxide film that protects against further oxidation. colouring It's not just a decorative element, it's a necessity, and if you buy a used boat, the first thing you do is assess the condition of the paintwork.
And you have to pay special attention to riveting places and welds, and that's where most of the time it starts. pittingIf you detect paint bloating or red spots, you need to clean the metal to shine and treat it with a rust converter, then apply the soil with zinc.
⚠️ Attention: It is strictly forbidden to use copper-containing antifouling paints or contact copper elements with the housing of D16T. This will lead to the instantaneous development of galvanic corrosion and through holes.
Modernization: installation of floating tanks and transmolants
One of the most popular improvements Progress 2 And the first thing you can do is you can put extra floating blocks in your nose, and you can fill your regular forepic with foam, but over time, it gets soaked in moisture, and you can replace it with sealed plastic tanks or stainless steel tanks, and you can make it a lot better. sluggishness boat.
The transom plate is also frequently upgraded, and the standard design is designed for old-style motors, and the modern high-power engines (20-30 hp) require a stronger transom, which is done by welding additional corners or installing stainless steel linings at least 4 mm thick.
☑️ Check-up before upgrade
When the transom is strengthened, it is important not to overload the stern. Shifting the center of gravity back can cause the boat to start to "buried" with its nose on the move, which is dangerous in choppy conditions. The optimal solution is to place a battery tank or anchor box in the nose for balancing.
The main principle of modernization is "do no harm"; any interference with the power set must be justified by calculations, otherwise you can violate the strength specifications of the body.
Repair of holes and restoration of geometry
Repairing a duraluminium case requires specific skills and equipment. Unlike steel, aluminum cannot be cooked by conventional electric arc welding in the air, it is instantly oxidized. ferro-argonoder (TIG) and a filler rod of the appropriate brand (usually AD or AD31).
If the hole is small (up to 5-10 mm), it can be closed by cold welding using glass-reinforced epoxy compounds. However, this is a temporary measure. Full repair involves cutting out the damaged area and welding the patch overlaid or joined with a lining bar.
The procedure for welding a patch:1. Clean the edges of the hole to pure metal.
Cut the patch with a tolerance of 15-20 mm.
3. drill the snatch holes.
4. Cook with short seams (1-2 cm) with breaks for cooling.
A common problem with older boats is the breakdown of bottom geometry ("bubble" or dents), which is done by cold-fixing using a sledgehammer and wooden or rubber hammers, heating the metal with a gas burner for editing. forbiddenAs the dural loses its tempering when heated and becomes soft (“released”).
⚠️ Warning: When you edit dents, never hit one place repeatedly. Move from the edges of the dent to the center, gradually leveling the profile to avoid thinning the metal.
Operation and maintenance of the boat Progress 2
Long life. Progress 2 It depends on how you treat it outside the water, and after every landing, especially in salt water, the body needs to be thoroughly rinsed with fresh water, and salt is the main catalyst for corrosion and destroys the protective layer of oxides.
Store the boat upside down or on special keel blocks that provide ventilation of the ceiling (bottom). If the boat is on the ground, you need to put soft gaskets under it to avoid point loads on the skin, which can lead to deformation of the frames.
Once a season, it is recommended to perform a review of fasteners. Bolts and nuts on aluminum boats are prone to "fitting"; They should be periodically twisted, cleaned threads and lubricated with graphite lubricant or compounds like Anti-Seize.
The Secret of Longevity
Many experienced water-engineers recommend that every 3-5 years completely remove the old coating, degrease the hull and apply a new layer of epoxy soil.
Comparison with analogues and final conclusions
Against the background of modern analogues of PVC or composite Progress 2 It looks like a heavyweight archaism. But in the metal boat niche, it has few competitors in terms of price and reliability. Kazanka-M is less seaworthy, and Ob often suffers from thin metal. Progress It is still a tank on the water.
The main advantage of the model is its maintainability: the punched side can be brewed in the field (with a generator), which you can not do with fiberglass or PVC. In addition, the aluminum body is not afraid of sparks, which is important for fishermen using open flames.
If you are looking for a boat for serious fishing, hunting or long hikes in large bodies of water, and you are not afraid of weight of 140 kg, then you can find a boat that is not dangerous. Progress 2 It's an investment in safety and confidence, proven by generations of water-powered motorists.
Which motor is best for Progress 2?
The optimal choice is the engines with a capacity of 15-25 hp (Yamaha, Tohatsu, Mercury). Motors up to 10 hp will be weak for full load, and over 30 hp may require serious transom gain and change of alignment.
Can I paint Progress 2 with a regular paint?
Conventional oil paints (PF) are poorly maintained and quickly peel off, and special non-ferrous metal soils (e.g., VL-023) and epoxy or polyurethane enamels intended for boats should be used.
How many people can accommodate Progress 2 by current standards?
Formally, the carrying capacity of 400 kg allows you to take on board 4 people (75 kg) plus equipment. However, for a comfortable and safe fishing with a large number of tackles, it is recommended to take 2-3 people.
Do I need to register Progress 2 in GIMS?
Yes, the weight of the curbed body (140 kg) exceeds the optional threshold of 200 kg only in combination with the engine. However, since the body mass is less than 200 kg, registration is required only when installing a motor with a capacity of more than 8 hp (or 10 hp, depending on the current interpretation of the law, it is better to check with the local office).
