The legendary boat Progress-4 has been one of the most recognizable symbols of domestic shipbuilding for lovers of water tourism and fishing for many decades. aluminum-motor The hull was designed to withstand long treks in Ladoga, Onega and even coastal seas, and combines ease of maintenance and seaworthiness, making it a popular choice among outboard motors up to 50 hp.
Unlike earlier models, the fourth version has improved bottom geometry and reinforced transoms, which has a positive effect on the stability of the wave, many owners value it for its maintainability: any welding seam can be restored in the field, and the shortage of spare parts for this model is almost not felt due to unification. Motor boat Progress 4 It often becomes the basis for experimental tuning, turning from a simple Kazanka into a full-fledged weekend cruiser.
However, despite its age, this boat requires a competent approach to operation and modernization. Modern materials and technologies allow you to significantly improve the comfort and safety of navigation, if you approach the issue of upgrade. In this article, we will discuss in detail the design features, nuances of control and proven ways to improve the performance of this legendary boat.
Design features of the body and materials
The basis of the reliability of the "Progress" is its body, made of aluminum-manganese AMG5M: This material is not chosen by chance: it has high corrosion resistance in fresh water and sufficient ductility to extinguish shock loads from waves without cracking. The skin thickness varies from 2 mm in the bow to 4 mm on the bottom, which provides the necessary margin of safety when faced with underwater obstacles.
The geometry of the hull contours is designed to provide acceptable germination per wave while maintaining stability in the parking lot. The cheekbones are pronounced, which helps the boat to stay on course more confidently when driving for an outboard motor. The interior is divided into compartments that perform the function of the function of the vehicle. floatability They are storage facilities, although the size of the latter is often criticized by fishermen for their small capacity.
⚠️ Warning: AMG5M aluminum alloy is sensitive to contact with copper and brass in salt water. When installing electrical equipment or brass fittings in marine conditions, be sure to use insulating pads to avoid electrochemical corrosion.
The transom plate is reinforced with linings and is designed for the hinge of engines weighing up to 80 kg, however, for comfortable operation with two passengers and cargo, it is better to focus on engines with a capacity of 25-30 hp More powerful engines can lead to excessive differentiation on the stern and reduced control safety at high speeds.
Technical specifications and driving performance
To objectively assess the capabilities of the boat, you need to refer to dry figures. Overall length The vessel is 4.0 meters, which allows you to comfortably accommodate 4-5 people, although the optimal load for maintaining driving performance is 2-3 people. Midwive width of 1.4 meters provides good stability, allowing passengers to move along the cockpit without a strong roll.
The optimal power of the engine for the Progress-4 with one driver and passenger is 15-20 hp, which allows you to reach speeds of up to 30 km / h and save fuel.
An empty boat is about 160 kg, making it heavy enough to be carried on the roof of a passenger car, but inert enough on the water to quench a small wave, with a maximum payload of 400 kg, including the weight of the engine, fuel and crew, and exceeding this limit is not only dangerous, but also leads to a sharp increase in the load. fuel-flow and slow down.
Driving qualities directly depend on the installation outboard And the right alignment, the boat is confidently going to plane with one person on board already at 12-15 hp, but on full load to get to the plane may require a motor of 25 hp, otherwise the boat will move in displacement mode, creating a large wave and consuming a lot of fuel.
Below is a summary table of the main parameters that will help you decide on the choice of equipment:
| Parameter | Meaning | Note |
|---|---|---|
| Full length | 4,000 mm | Dimension for transportation |
| maximum width | 1400 mm | Midwidth |
| Height of board | 500 mm | Midle. |
| Load capacity | 400 kg | Including engine and fuel |
| Passenger capacity | 4 people. | 2-3 recommended |
Cockpit control and ergonomics
Progress-4's ergonomics were created in an era when comfort requirements were different from those of today, but the basic principles were well laid. The deck has a non-slip coating (in the factory version - ruffling or linoleum pasting), which is critical for safety in wet weather. Banks. (seats) are located across, which is not always convenient for long transitions, so many owners replace them with soft hazelnuts.
The motor is controlled through pulp The standard place for installation of the instruments is located on the bulkhead of the front cockpit polish, but often it is left empty or occupied by the navigator. To improve visibility and convenience, many enthusiasts move the control console to the center, freeing up their nose for fishing or installing an inflatable boat.
Wind protection is an important aspect, and the boat is not equipped with awnings, so the installation is not complete. cross-plate And if you're going to walk in cold weather, or windshields, you're going to be the number one challenge for those who plan to walk in cold weather, and without protection from the oncoming flow of air, long transitions become a test of strength, especially in the off-season.
Tuning and modernization of the boat
Progress-4 tuning is a separate culture that allows you to turn an ascetic iron into a comfortable boat. balloon Not only does this increase stability and unsinkability, but it also adds internal shelves to store gear, and it also protects the sides from impacts on the pier.
The second important element of modernization is the creation of a full-fledged cockpit with a soft-seat It allows you to use the interior space more efficiently, hiding anchors, life jackets and tools under the seats, and also, soft elements significantly reduce fatigue from vibration and shocks to the wave.
The secret to a quiet move
To reduce noise from the motor and wind, many owners paste the inside of the body with vibration insulation materials on a bitumen basis, which also improves thermal insulation.
And the lighting system, too, is that by putting LED tapes around the perimeter of the cockpit and having a powerful spotlight on the nose, the boat is a versatile tool for night fishing. battery Allows you to power all this electronics without the risk of discharging the starting battery of the engine.
⚠️ Attention: When installing additional equipment (echo sonars, navigators, powerful acoustics), watch the weight distribution. Shifting the center of gravity in the nose or on board can dramatically change the behavior of the boat on the water and make it dangerous.
Maintenance and repair DIY
One of the main advantages of the boat is the ability to hand-craft Aluminum is easily welded, and small holes can be sealed even by cold welding in emergency cases. Regular maintenance consists of inspecting welds, especially in the area of the transom and zygomatic bends, where the stress concentration is maximum.
To extend the service life, it is recommended to clean the shell of fouling and apply special compositions to prevent oxidation annually before being put into winter storage. graffiti: If you use a short-dadewood motor, make sure the spray doesn't get into the exhaust system, which can lead to hydraulic shock.
☑️ Seasonal TO boats
If you find a leak, don't rush to brew it right away. Often, water comes through poorly installed rivets or through wire entry points. Using a sealant for aquariums or polyurethane compounds can solve the problem without welding.
Security and GIM regulations
Operation of any boat requires compliance with the rules of safety on the water. "Progress-4" is mandatory. registrationSince its mass with an engine exceeds 200 kg (or the power of the engine is more than 8 hp, depending on the current interpretation of the law, but usually this boat is registered), the presence of life jackets by number of passengers, anchor with a line and a scoop is a mandatory minimum.
When approaching a thunderstorm front, you should immediately go ashore or take cover, since the risk of lightning striking a metal object on the water is extremely high. shore-distance - for open water bodies without special equipment, it is 3 km.
⚠️ Warning: Never use chainsaws or open flames to dry or heat inside a closed boat cockpit. Gasoline vapors are heavier than air and accumulate in the hold, creating an explosive mixture even when the tank is off.
Following these simple rules will allow you to enjoy water trips for many years, keeping the boat in excellent condition. Progress 4 is a reliable companion who, if properly cared for, will serve several generations of your family.
Frequently Asked Questions (FAQ)
Which motor is best for Progress 4?
The best choice is 15-25 hp (Yamaha, Tohatsu, Mercury) engines, which provide a confident getting on plane with load and are economical. You can install engines more powerful than 30 hp, but this requires experience in driving and may require additional hydrowings to stabilize.
Do I need to register the boat Progress in GIMS?
Yes, in most cases registration is mandatory: the weight of the boat (about 160 kg) plus the weight of the engine (over 40 kg) exceeds the threshold of 200 kg, which requires registration and ownership of a small vessel of the category “motolubka”.
Can Progress 4 be used at sea?
Use is possible in the coastal zone with a gentle coast and in the absence of heavy chop (up to 0.5-0.75 meters). The design of the boat is not designed for the surf or open sea due to the low side and lack of self-flow.
How do you speed up the boat?
Speed can be increased by installing a hydrofoil on a lower unit engine, using a screw with a modified pitch for a specific load, as well as by simplifying the design (replacing heavy cans with light haldukes) and installing boules to improve hydrodynamics.
