Soviet aluminum-boatThe Progress 1 model, which became a symbol of affordable water transport for millions of citizens in the middle of the last century, ushered in a new era in amateur shipbuilding in the late 1950s, offering fishermen and tourists a reliable alternative to wooden boats and heavy boats. The hull design, made of aviation alloy, provided lightness and durability, which was critical for operating conditions away from civilized parking lots.
Today, decades after mass production ceased, Progress 1 The owners of old buildings are slow to part with the time-tested metal, preferring to restore and improve it, rather than buying modern plastic counterparts. design This boat is necessary for everyone who wants to restore the rarity or correctly fit it into the modern realities of fishing and recreation.
In this article, we will discuss in detail the technical parameters, features of operation and the possibilities of upgrading this legendary vessel. You will learn how to properly prepare the hull for the season, which engines are best suited and which ones are best for the future. constructional They require special attention during repairs.
History of creation and design features
The boat was developed at the Kuibyshevsky Gorky Plant, where engineers set the task of creating the most simple and technological product for the mass consumer, the body was designed with the expectation of installing an outboard motor, which was a revolutionary solution for small craft. duraluminiumIt allows you to reduce the weight to acceptable values, while maintaining high strength for impact and abrasion.
The Progress 1 hull is a simplified version of the larger motorboats' contours, and the flat bottom in the bow smoothly becomes a slight wicked curve in the stern, which provides a good wave germination if properly loaded, the sides have a small breakup, and the transom is reinforced with a wooden lining that protects the metal from vibration and corrosion when the engine is running. sink-board It is often the first object of attention in restoration.
Why duraluminium?
Duraluminium (D16T) was not chosen by chance, it has high specific strength and corrosion resistance, but, unlike pure aluminum, dural is prone to electrochemical corrosion when in contact with copper or brass in salt water, so requires high-quality insulation of the fastener and regular anticort treatment.
Importantly, the earlier versions of the boat had a slightly different frame configuration, which affected load distribution, and during operation it was found that some knots required reinforcement, so in later series additional reinforcements were introduced. stringer This made the body more rigid and allowed for more confident use of engines with a capacity of up to 10-12 horsepower.
Technical specifications and dimensions
For proper planning of operation and selection of equipment, you need to clearly represent dimensions Progress 1 is a small rowing boat and motor boat, which imposes limits on the number of passengers and engine power, and accurate knowledge of the specifications will help to avoid overload and ensure safety on the water.
Below is a table with the main technical data relevant for standard factory equipment:
| Parameter | Meaning | Note |
|---|---|---|
| Longest length | 4.00m | Including forespiegel |
| maximum width | 1.60m | On the sides. |
| Height of board | 0.50 m | Midle |
| Hull mass | ~70 kg | No equipment. |
| Load capacity | 400 kg | Including engine weight |
The boat is designed to hold three people, but the real boat is loading capacity It allows two adults to comfortably accommodate with a full suite of fishing gear. An increase in the number of passengers is possible, but it significantly reduces driving performance and increases draft, making the sides dangerously close to the water. The recommended engine ranges from 3 to 10 hp, which allows speeds up to 20-25 km / h depending on the load.
Operational features and driving performance
Progress 1's performance is directly dependent on the bottom and weight distribution, and the flat bottom provides excellent parking stability, allowing you to fish confidently even with active cliffs, when you need to stand up sharply or move on deck. However, at full speed, this shape creates significant resistance, requiring significant resistance. balancing engine and cargo.
When moving against the wave, the boat behaves predictably, but the hardness of the impacts on the water is felt stronger than that of modern inflatable or keel plastic counterparts. shock-absorbing on the cans and seats.
⚠️ Attention! Aluminum housing cools quickly in the wind. For long transitions in cold weather, be sure to carry thermal insulation mats or plywood decks to avoid hypothermia through contact with metal.
The boat's handling is improved by installing transax plates or using a hydrofoil on the engine, which allows Progress to go faster for planing, even with one operator on board. Without planing, the boat is confidently steering, but the speed rarely exceeds 10-12 km / h even with a powerful engine due to the large area of wetted surface.
Restoration and repair of the hull
Rebuilding the old Progress is a time-consuming but rewarding process. The first step is always full-time. defectionYou need to thoroughly wash the boat, remove the old colorful layer and carefully examine the metal for cracks, especially in the area of the zygomatic bends, the attachment of the transom and the forehead, and these are the areas that experience maximum stress when hit by a wave.
The best way to fix cracks and holes is to use argon welding with a filler material of the same brand as the base metal. The use of cold welding or epoxy compounds only gives a temporary effect, since aluminum has a high thermal expansion coefficient, and sealants lose elasticity over time. ferro-welding It guarantees the monolithicity of the seam and the durability of the repair.
☑️ Stages of the restoration of the building
After welding, the surface must be cleaned and treated with a rust converter if there are oxides, followed by the stage of priming with special compounds for non-ferrous metals and finishing. corrosion-coating And you can check the condition of the wooden elements, the flooring, the banc and the squirrel board, and replace them with new ones that are soaked in oil or varnish.
Modernization and tuning of boats
Progress 1 tuning often starts with installation steeringThe standard equipment involved the control of the tiller, which is inconvenient for long transitions or fishing by trolling. Installing remote control (gas-reverse) and the steering wheel radically changes the ergonomics, allowing you to sit in a comfortable chair and control the situation.
The second popular redesign is the bow refit, and many owners cut the sharp forespigel and weld a flat area to install the anchor winch or the extra boot, and often reconfigure the cans to make them removable or rotary to make room in the center of the cockpit for the purpose of refurbishing the cockpit. fishing-equipment.
To improve driving performance, install small transom plates (interceptors) on the transom, which will help the boat to go faster for planing and improve the course stability on the waves.
And soundproofing, which means that polyurethane foam or special vibration-proofing materials can reduce noise levels by 30 to 40 percent, makes the boat much more comfortable and allows you to hear the sniffs or conversations of the interlocutors. Heat insulation It also plays a role if you plan to spend the night in a boat.
Comparison with modern analogues
Compared to modern aluminum boats, Progress 1 wins in price and maintainability, but loses in comfort and weight. Salute and BadgerThey often have more complex contours that provide better seaworthiness, but they tend to be more expensive and require more careful handling of thin metal.
Plastic boats (FRP) offer even more comfort and no need to paint, but they are afraid of sharp stones and require a special trader to carry, as they often have more weight. "Progress" in this regard is universal: it can be dragged along the shore, loaded into the back of a pickup truck or even flipped and stored in the open air (although the latter is not recommended). The main advantage of Progress 1 is its “unkillability” with minimal maintenance costs.
When choosing between rebuilding an old Progress and buying a new boat, weigh your priorities. If you want a simple, maintainable workhorse for fishing in hard-to-reach places where you can scratch the side against a driftwood, Soviet aluminum is the perfect choice. If speed, comfort and aesthetics are the priority, consider modern options.
Progress 1 remains relevant due to the simplicity of the design, low cost of ownership and the ability to self-repair in any conditions without special equipment.
Can I install a 15 hp engine on Progress 1?
Technically, it's possible, but it's not safe. The power rating for this model is up to 10-12 hp. Excessive power can lead to transom collapse, loss of stability and even tipping the boat on a turn. If you do this, be sure to strengthen the transmuter plate and install a traction limiter (anti-cavitation plate) on the engine.
Which paint is best for an aluminum case?
It is best to use specialized epoxy or polyurethane paints for aluminum. Before painting, it is mandatory to treat phosphate primers (for example, VL-023), which provide adhesion and additional anti-corrosion protection. Conventional oil paints will quickly disintegrate.
Do I need to grease the bottom of the boat before each descent?
Lubrication (like silicone) makes it easier to slide off the runners and reduces fouling, but it's not mandatory. The main thing is to monitor the integrity of the paint coating. If the paint is intact, no additional lubrication is needed. If metal is, the lubricant can temporarily protect against oxidation, but it's better to paint over the damage.
