The era of Soviet shipbuilding gave domestic water engines many legendary samples, but it is the aluminum-boat They have a special place in the hearts of outdoor enthusiasts. Progress 2The first boat, which was born in the early 1960s, was a direct successor and improved version of the famous Kazanka, an attempt by engineers to create a versatile vessel that could safely navigate reservoirs without giving way to river boats. cockpitThis has dramatically improved the safety of swimming in the oncoming wave.
Today, despite the abundance of modern PVC materials and composites, interest in this “iron” classic is not fading. Many owners are looking for detailed drawings and technical data to restore the rarity or competently tune the old hull. The reliability of the D16T aluminum alloy allows these boats to stay afloat for decades, outliving their owners. However, before you acquire such “Progress”, you need to clearly understand its real capabilities and limitations.
History of creation and features of the construction of the body
Development Progress 2 It was conducted at the Kazan Aviation Plant, where aircraft technology was successfully applied to products, the main difference from its predecessor was the shape of the contours. V-shaped contours It had a keeliness of up to 9 degrees in the nose, which allowed the boat to steer its course with confidence and to be more easily ascended, although it required an increase in the engine power to get on plane.
The body was assembled from sheets of aluminum-magnesium alloy by riveting, which provided high leakage and maintainability in the field. boulder They were special buoyancy boxes in the nose, which also served as rundooks, and they not only increased stability, but also protected the nose from being overwhelmed by water.
⚠️ Warning: When buying a used boat, be sure to check the condition of riveted seams under the boules. This is where corrosion most often occurs due to constant contact with water and dirt.
The trans manose design also changed, making it more powerful and designed to accommodate outboard motors up to 30 hp (although the passport often listed 20 hp), making it versatile, both for quiet fishing from Neptune 23 and for high-speed walks with more powerful vortices.
The main structural feature of Progress 2 is a V-shaped body with a false bort, which favorably distinguished it from its predecessors and ensured seaworthiness.
Main dimensions and weight parameters
For the correct selection of the trailer and calculation of the carrying capacity of the vehicle, you need to know the exact dimensions. Progress 2 The full length is 4100 mm, which is the optimal size for transport on a standard passenger trailer without the need for special permits.
The width of the hull on the midfield is 1510 mm. This is narrow enough to comfortably accommodate three people in a row, but it is enough for two anglers with gear. The height of the board, taking into account the false board, reaches 720 mm, which creates a sense of security and allows you to safely catch fish standing, leaning on the side.
Weight specifications play a key role in the operation of:
- 🛶 Weight of the body without equipment: about 140 kg (depending on the year of production and configuration).
- 👥 Passenger capacity: up to 4 people (according to GIMS standards).
- 🎒 Cargo capacity: 400 kg (including weight of people and equipment).
- ⚓ Allowable power of the motor: up to 30 hp
It's worth noting that the claimed 400kg load capacity is theoretical. In practice, for a confident planing with two passengers and a full tank, it's better to focus on smaller values. seaworthiness and speed.
Table of technical specifications
To organize the data and avoid confusion with modifications, below is a summary table of the main parameters. Progress 2 with other models or assess the need for modernization.
| Parameter | Meaning | Note |
|---|---|---|
| Longest length | 4.10m | Excluding the attachments |
| largest width | 1.51 m m m | Midel-spangout. |
| Height of board | 0.72 m | Including the bulwark |
| Hull mass | 140 kg | Average value |
| Passenger capacity | 4 people. | Passport. |
Note that the body weight may vary. Earlier versions may have been heavier due to the thickness of the metal, and later modifications such as: Progress 2MThere were minor changes in the design of the transom and the mounting of the cans. In any case, the weight of 140 kg requires a reliable trailer or winch to be launched into the water.
The size of the cockpit allows you to install windshield It's a small awning that turns the boat into a full-fledged weekend tourist boat, but you have to remember that the addition of additional equipment will increase the overall weight and reduce the payload.
Operational and seaworthiness
How he behaves. Progress 2 This is probably the most important question for the potential owner, because of the V-shaped contours, the boat is much softer than flat-bottomed counterparts, it does not prowl as much on the course and allows you to reach speeds of 35-40 km / h with a motor of 20-25 hp at full load.
Stability is high. The wide boulay boxes in your nose prevent difference. You can easily go from side to side to pick up gear or check your engine. But at high speeds, when you're in a steep wave, you can hit the bottom, so you need to drop the gas before the crest of the wave.
The secret of sustainability on course
To improve course stability, many owners install small zygomatic keels or fins on the transom, which reduces yaw at high speeds.
The important thing is splashiness, and the Falshbort is great at spattering when it's in calm water, but if you go against the wind and the waves, the nose can start to draw water. effluent (scoops) or pumps are a prerequisite for safe operation.
⚠️ Warning: Aluminum housing is very sensitive to impacts on rocks at speed. The bottom is 2 mm thick and easy to penetrate, so be careful in shallow water.
Engine compartment and power recommendations
Tranza Progress 2 The standard height of the transom allows for standard-length lower unit engines. The manufacturer recommended engines up to 20 hp, but the case has shown that the body can withstand 30-horsepower units.
When choosing a motor, the weight of the suspension should be considered. Heavy two-stroke engines of Soviet production ("Whirlwind", "Neptune") shift the center of gravity back, which may require transferring solder cans or cargo to the bow for balancing. Modern four-strokes are lighter and more compact.
- 🚤 Optimal power: 15-20 hp for fishing and cruising.
- 🏎️ Maximum power: up to 30 hp for high-speed planing.
- ⛽ Fuel consumption: depends on the engine, but the body is economical due to contours.
The motor is fastened through standard rods, and it's important to monitor the condition of the wooden transom (if it's preserved) or the metal pad, and rotten wood or rusty metal is a direct road to losing the motor.
☑️ Checking before getting on the water
Tuning, modernization and restoration
Progress owners are creative, and tuning these boats has become a separate business, and most often, modernization starts with replacing the pile decks, and the old wooden slats rot, and they're replaced with carpet-coated moisture-resistant plywood or grooved aluminum.
The second popular stage - installation steeringA regular roamer is not always convenient, especially when long-distance transitions, installation of a cable steering system (for example, from the "Seafarer" or imported analogues) significantly increases comfort, and often change the windshield to a higher one or install a frame under the awning.
Rebuilding the body requires thorough defects. If cracks are found in riveted seams, they must be re-opened or, in extreme cases, brewed with argon (although welding for the D16T is a complex process that requires skill).
When replacing wood elements, use larch or moisture-resistant PVF plywood soaked in olifu, which will extend the life of the decking several times.
Some enthusiasts go further and install a control console, sonars, GPS navigators and powerful LED backlight. Progress 2 It is transformed into a modern boat, preserving its unkillable soul.
Frequently Asked Questions (FAQ)
What is the real speed of the boat Progress 2 with a 20 hp engine?
At full load (2 people + equipment) the speed is about 30-32 km / h Alone with a full tank can accelerate to 35-38 km / h With a motor of 30 hp the speed can reach 40-42 km / h.
Is it possible to go to Lake Ladoga or Onega on Progress 2?
You can only go out in cool weather and off the coast, and despite the bulwark, it's still a small boat, and the big open water with the sudden wave is dangerous for boats 4 meters long.
Do I need to register Progress 2 in GIMS?
Since 2012, small vessels weighing up to 200 kg and up to 8 kW (about 10.8 hp) are not subject to registration. Progress 2 weighs about 140 kg. If you put the engine up to 10 hp inclusive, registration is not required. The engine is more powerful - registration is mandatory.
Where can I find the plans for restoration?
Original drawings can be found in the archives of KYA magazines (boats and yachts) from the 60s and 70s or in specialized powerboating forums. Often enthusiasts post scanned passports with dimensions.
