Progress Aluminum boats have been a symbol of reliability and availability in domestic waters for many decades. The Progress 2 model, an improved version of its predecessor, has earned special popularity due to its increased dimensions and improved stability. specification This vessel allows you to use it not only for fishing in the coastal zone, but also for serious walks on large reservoirs.
Owners value this model for its simplicity of design and maintainability, which is critical for operation in remote areas. The body, made of aluminum-magnesium alloy, perfectly resists corrosion and mechanical damage. In this material, we will analyze all the parameters of the vessel in detail so that you can make an informed decision about the purchase or modernization.
It is worth noting that even years after the release, these boats remain in demand in the secondary market, their design is tested by time and the harsh conditions of Russian nature. Progress 2 will help to properly prepare the boat for the season and avoid common errors in operation.
History of creation and design features
Development of the boat Progress 2 The project was conducted between 1966 and 1969 at the Kuibyshev Aircraft Plant, where engineers were tasked with creating a more spacious and safe version of the popular Progress, while maintaining the technological efficiency of production, resulting in a vessel with higher sides and altered bow geometry, which had a positive effect on the performance of the vehicle.
The main difference from the previous model was the use of more advanced riveting technology and the use of high-strength alloys. hull It became stiffer, and the transomb was reinforced to allow more powerful engines to be installed, which allowed the boat to expand its functionality significantly, turning it from a simple rowing boat into a full-fledged motor boat.
The design includes a deck covering the bow, which significantly improves the safety of the crew in chop, formed a luggage compartment that can be used to store equipment or install an additional fuel tank, this layout has become the standard for many subsequent models of domestic shipbuilding.
⚠️ Warning: When buying a used boat, be sure to check the condition of rivet seams in the bow. This is where microcracks most often occur due to shocks against the wave at high speed.
A unique feature of this model is the ability to install two-engine With a combined power of up to 25 hp, which is an outstanding performance for boats of this class, this flexibility in the choice of powerplant makes Progress 2 a versatile tool for various tasks.
Overall dimensions and weight parameters
One of the key factors influencing the choice of a floating craft is its physical size. Dimensions Progress 2 allows four adult passengers to comfortably sit on board, making the boat ideal for family vacations, while remaining compact enough to be transported on a standard trailer.
The weight of the structure is an important parameter when planning a launch. the D16AT aluminum alloy used in the manufacture provides the optimal strength-to-weight ratio. However, it is worth considering that the total weight of the equipped boat will be significantly higher than the data-sheet figures.
For clarity, the main parameters are summarized in a table:
| Parameter | Meaning | |
|---|---|---|
| Longest length | 4,500 mm | |
| largest width | 1600 mm | 150 kg |
| Load capacity | 400 kg | |
| Capacity | 4 people |
As you can see from the data, loading capacity 400 kg allows you to carry not only passengers, but also a significant supply of equipment, fuel and water, which is critical for multi-day expeditions, where every kilogram of cargo matters.
Navigability and sustainability
Progress 2’s seaworthiness is highly appreciated by experienced water-engineers, with its high zygomatic bend and sharp bow allowing the vessel to confidently hold a wave up to 0.6 meters high, which allows it to venture into large bodies of water, such as Lake Ladoga or Lake Onega, in relatively calm weather.
The stability of the boat is ensured by the competent distribution of volumes and the width of the hull. Even with a sharp movement of passengers from side to side, the roll remains controlled. Kieliness The bottom helps to reduce the impact loads on the body during the course of the excitement, making the movement more smooth.
But remember the limitations of the flat stern, and when you move against a steep wave, you can have slap stern, which reduces comfort and speed, and proper loading and weight distribution help minimize this effect.
⚠️ Attention: Do not develop full engine power when sideways turbulent. A sharp roll can lead to splashing of the cockpit or, in the worst case, loss of stability.
To improve seaworthiness, install additional bushprits or a bow breaker that will take the first wave shock, preserving the integrity of the aluminum board.
In calm weather, the boat demonstrates excellent handling and stability, which is especially important when fishing by trolling or when driving in the dark, when maximum predictability of the vessel's behavior is required.
Power plant and speed specifications
The choice of engine for the Progress 2 is a balance between the desired speed and economy. The manufacturer recommended the installation of engines with a capacity of 12 to 25 hp. Whirlwind-20 and Whirlwind-25, which allowed to reach speeds up to 40 km / h with full load.
Modern imported engines are also great for this model, but require careful selection of the lower unit. Too short leg can lead to cavitation and loss of traction, especially when driving at full load, the optimal is a motor with a lower unit of 381 mm (15 inches) or the use of supercharges.
- 🚀 The maximum speed with a 20 hp engine is about 38-40 km / h.
- ⛵ Cruising speed for economical travel is 25-30 km / h.
- ⚓ The minimum power for confident planing is 8-10 hp.
- ⛽ Fuel consumption at cruising speed is about 6-8 liters per hour.
It is important to set up correctly differentiation Shifting the engine or installing transom plates can have a significant impact on the plane output and top speed, and experimentally you can find a position where the boat goes with minimal water resistance.
Secrets of engine tuning
To achieve maximum speed, try to raise the motor a little on the transom ( 1-2 cm above the standard), which will reduce the resistance of the lower unit, but requires caution not to disrupt the flow of water to the propeller.
With two engines up to 25 hp, the speed performance improves slightly, but reliability and safety improves significantly, and if one engine fails, the second one will make it possible to get to the shore on its own.
Internal arrangement and ergonomics
The ergonomics of the Progress 2 cockpit are designed to provide comfort on long hikes, and the presence of rundooks in the nose and under the paioles allows for rational use of space. Banks. (seats) are made in the form of slamming covers, which gives access to the internal compartments for storing things.
Deck coatings are often made of plywood or wood covered with linoleum or paint, which prevents slipping and protects the feet from the cold of metal. Many owners are upgrading by installing soft removable cushions on cans, which turns hard seats into comfortable places to relax.
The bow area provides a place for windscreen installation, which significantly improves the conditions of stay in the boat when moving, the space under the deck is ideal for housing sealed boxes of food or sleeping bags, protecting them from splashes.
☑️ Testing season readiness
There is no lighting for the interior as standard, but owners often install autonomous LED lamps on suction cups or magnets, which allows you to easily navigate in the dark and find the necessary things in the handuks.
Maintenance and durability
Progress 2 aluminum case requires no maintenance, but periodic monitoring is a must. The main enemy of the metal is electrochemical corrosion, which occurs when it comes into contact with other metals in salt or even fresh water, so it is important to monitor the condition of zinc protectors, if they are installed.
Regular washing of the boat with fresh water after entering the salt water bodies prolongs the life of the coating, special attention should be paid to the places where the motor and keelson attachments, where moisture and dirt most often accumulate. Colouring The bottom with special antifouling compounds prevents the fouling of algae in the summer.
When stored in winter, it is recommended to install the boat on special keel blocks or suspensions to avoid deformation of the hull under its own weight.
⚠️ Note: When welding or repairing the case, only use argon welding and wire of the same brand as the case. Using steel tools on aluminum can trigger the corrosion process.
Timely replacement of rotten wooden elements (cans, floorboards, quills) is also a must-have, and wood that comes into contact with wet aluminum is destroyed over time and can contribute to the oxidation of the metal.
The main resource of the "Progress 2" durability is regular visual inspection of the seams and proper storage in the off-season. Aluminum does not rust like steel, but requires protection from electrochemical processes.
