Legendary Progress 2 It remains one of the most popular aluminum boats in the post-Soviet space, despite its age, and many owners are wondering how to turn this robust but heavy and noisy hull into a modern vessel that can compete with new models of PVC or composite. Boat tuning Progress 2 It can significantly improve seaworthiness, reduce noise and improve safety with minimal financial investment, but it is worth remembering that any modernization requires an engineering approach and an understanding of the physics of the sliding vessel.
In this article, we'll look at time-tested techniques that actually work on water, how to install transom plates, whether to sew up your nose, and how to effectively combat vibration and noise, and we'll focus on specific technical solutions that apply to this model rather than looking at abstract tips. Critical: any tuning should not increase the total weight of the vessel beyond the permissible norms, otherwise the boat will lose plane even with a powerful engine. Preparation for the modernization begins with a thorough analysis of the current condition of the hull.
Background analysis and work planning
Before you take up the tools, you need to objectively assess the condition of your boat. Progress 2 It has a 2 mm thick duraluminum hull, which is a trade-off between strength and weight. Often owners face the problem of yawing on the course and low landing of the stern when loading. Planning should begin with defining the main goals: which is more important - speed, comfort or stability? Without a clear plan, you can turn the boat into an unguided projectile.
Special attention should be paid to checking the seams and rivets. The old case may have microcracks, which, when reinforced or additional equipment is installed, can become critical. defectiveness If you are planning to install a powerful motor, be sure to check the condition of the transom, since the regular engine compartment is designed for lower-power engines.
⚠️ Warning: Before starting any welding or drilling holes in the bottom, make sure there are no residues of fuel near, as gasoline vapors in an enclosed space can cause an explosion when the metal is heated.
There are several modernization areas, each of which solves the problem, depending on your style of skiing and operating conditions, some people chase speed, others prefer calm fishing in windy weather.
- 🚀 Increased speed and output to plane due to changes in the geometry of the bottom.
- 🛡️ Improved safety and unsinkability by installing buoyancy blocks.
- 🔇 Reduce noise and vibration levels for crew comfort.
- 🎣 Adaptation for fishing: installation of platforms, anchors for sonar and tudu.
Upgrade of the bottom and installation of transom plates
One of the most effective improvements for Progress 2 And the flat bottom of the boat often causes the boat to go down with the stern, creating a lot of drag. The slabs, set at an angle, press the stern, put the hull in a clean planing and reduce fuel consumption. classicThis is a very effective result even at small capacity.
You can make the plates yourself from a 3 to 4 mm thick dural sheet, or you can buy the aluminum solutions that you've got to make. It's important to calculate the angle of attack and the mounting point correctly. Too big a angle can lead to yaw, and too small can't work. The mounting should be rigid, preferably on sealed bolts to keep water out of the rundock.
Besides the stoves, many owners practice sewing the nose. Progress 2 It's prone to burrowing on the wave, and if you put zygomatic splashers in place, or if you put a complete nose closet (and then you put an anchor lock in), you change the fluid dynamics, you get softer on the move, you stop slapping on the wave, you get better on the course, but it adds weight, which requires compensation.
- ⚓ Installation of zygomatic stringers to improve course stability.
- 📐 Manufacture and installation of transom plates with an adjustable angle.
- 🔨 Stripping the nose to reduce splash formation.
- 🛢️ Installation of additional fuel tanks in the nose for balancing.
When installing any elements on the bottom, use high-quality sealants and anti-corrosion compounds. Aluminum is prone to electrochemical corrosion, especially in places of contact with stainless steel or copper. All fasteners should be of the same material or insulated with gaskets.
Strengthen design and reduce noise
Noise is the second most popular disadvantage Progress 2The aluminum body resonates perfectly, turning the wave splash and the engine into a deafening crash. To combat this, a set of measures is used, including vibration insulation and noise insulation, the most effective method is to paste the inner surfaces with asphalt-based vibration-dumping materials.
The process of noise insulation is laborious and requires dismantling of all the internal elements. The surface must be defatted and warmed up to make the material fit better. You don't have to try to seal 100% of the area, just cover 60-70%, paying attention to flat sections of the bottom and sides, which will reduce the resonance and make the stay in the boat more comfortable.
What materials are best used for noise insulation?
For boats, specialized asphalt-based vibration plastics (for example, Vibroplane or analogues) are best suited, which are not afraid of moisture and temperature changes. The use of construction noise insulation for dry rooms is unacceptable, as it will quickly gain moisture and lose properties, and can also become a hotbed of corrosion.
Strengthening is often necessary when more powerful motors are installed. The standard frames may not withstand the increased loads. In this case, additional duplicate elements are installed from the profile pipe or corner. It is especially important to strengthen the engine mounting area and zygomatic joints, which increases the overall rigidity of the body and reduces metal fatigue.
| Materials | Thickness, mm | Weight sq.m., kg. | Efficiency |
|---|---|---|---|
| Silver Vibroplastic | 2.0 | 3.0 | Medium |
| Vibrosplop Gold | 2.3 | 4.2 | High. |
| Bimast Bombs | 3.0 | 5.8 | Maximum |
| Splen (noise insulation) | 4.0 | 0.6 | Additional |
Remember, every kilogram of noise insulation is a lost load capacity. balance After pasting, it is recommended to cover the materials with decorative plating made of plywood or plastic, which will also give an additional sound insulating effect.
Organization of internal space and cockpit
ergonomics Progress 2 It's far from ideal, so interior tuning is a must. Standard cans are often uncomfortable and take up a lot of space. Replacing them with soft seats with rundooks inside allows you to combine comfort with storage. Rundooks can be used to accommodate life jackets, anchor gear or spare fuel.
The engine compartment is an important element, and the installation of a removable podium for an outboard motor facilitates access to the transom and engine maintenance, the podium also protects against spray flying through the cutout of the transom, and for anglers, the installation of a platform for mounting the sonar and spinning holders, which do not interfere with movement on the boat, is important.
☑️ Checklist for cockpit arrangement
Lighting and electrical equipment also require attention, and installing LED bands around the perimeter of the sides will not only decorate the boat, but also ensure safety when fishing at night, wiring should be laid in corrugated tubes protected from water, and connected through a separate battery to avoid draining the starting one.
- 💡 Installation of LED lighting perimeter and runduks.
- 🪑 Manufacture of soft seats with internal drawers.
- 🔋 Organization of a separate compartment for battery with ventilation.
- 📱 Installation of holders for gadgets and navigation.
When planning the interior, avoid sharp corners and protruding elements. In the tight space of the boat, there is a high risk of getting caught by clothes or equipment. All elements must be securely secured, as an unsecured object can become a dangerous projectile in the wave.
Selection of power unit for the modernized boat
Boat tuning often involves changing the engine. Progress 2 It's often not enough, especially when you're fully loaded, but blindly increasing power can be dangerous, passport load capacity and stability must be considered, and the optimal range for tuning progress is the range of 20-30 hp.
When installing a motor with a power of more than 15 hp, the installation of hydraulic lift and electrohydraulics is highly recommended, which will allow you to change the different on the go, which is critical for flat bottom boats. The correct different allows you to compensate for the shift in the center of gravity when you load different loads.
⚠️ Warning: Installing a motor more powerful than 30 hp on Progress 2 requires a major alteration of the transax plate and may be unsafe due to poor stern stability.
An important aspect is the selection of the propeller. For a heavy boat with passengers, you need a screw with a smaller pitch to ensure quick access to the plane. For single riding, you can put a faster propeller. Experimenting with propellers is the cheapest way to improve the performance of the boat.
Use a tachometer to pick up the propeller: the motor must go to maximum speed (according to the passport) when the boat is fully loaded. Underwhelming or torsion of the engine reduces its life.
Safety and unsinkability
Any tuning should not come at the expense of safety. Progress 2 It has built-in buoyancy blocks, but over the years of operation, polyurethane foam could become saturated with water and lose its properties. In large-scale work, it is recommended to replace the regular foam with modern closed-mesh materials or install additional sealed blocks (flotation cylinders).
The installation of alarms and water level sensors in the hold will be a great addition. An automatic pump activated by a water level sensor can save the boat in the event of a hole or a strong splash. These systems are inexpensive, but their importance is hard to overstate.
Keep in mind visual visibility, brightly coloring your nose or installing reflective elements will help other boatmasters spot you in dusk or fog, and safety is not only technical condition, but also visibility on the water.
The main principle of tuning is that any change in design should be reversible or compensated, and crew safety is always a priority over speed records.
Results of modernization and economics of the project
To summarize, we can say that tuning Progress 2 It's a creative process that brings new life to the old hull, and the cost of upgrading is typically 30 to 50 percent of the cost of a new comparable size boat, but you get a vessel that's perfectly tailored to your personal needs, and the key is to take your time and do all the steps in a good way.
The result of a competent modification is a boat that goes faster on the plane, quieter goes, softer wave and easier to operate. This prolongs the life of the hull and increases the pleasure of resting on the water. However, remember that after serious changes (especially with weight and stability), it is advisable to undergo a re-registration or consultation with the GIMS, if required by law.
How much does a full tuning Progress 2 cost?
The cost varies greatly from materials and skills. Independent work using budget materials (vibroplastics, plywood, FFS, paint) will cost about 15-25 thousand rubles. If you order work in the workshop and use premium materials, the amount can grow to 60-80 thousand rubles and more, not counting the cost of the engine.
Do I need to take the boat off the register before tuning?
Under current regulations, unless you change the basic specifications (length, width, body material, engine type) drastically and change the name, re-registration is usually not required. However, if you change the transom under a higher-powered engine, this can be considered a change in design specifications, and the GIMS inspector may require changes in the documents.
Can I paint Aluminum Progress in any color?
Theoretically, you can, but aluminum requires special training. Conventional paint will quickly peel off. You need to use special soils for non-ferrous metals (for example, zinc-based) and two-component epoxy or polyurethane paints designed for aluminum. The best option is anodizing, but for large housings it is difficult and expensive.
How often should I change the anodic protection after tuning?
The frequency of replacement of zinc treads depends on the conductivity of the water and the intensity of operation. In salt water (sea) - once a season or even more often. In fresh water - usually every 2-3 seasons. When installing new equipment (especially of heterogeneous metals), the control of the treads should be strengthened.
