Aluminum small-sized vessels of Soviet production still cause keen interest among fishermen and lovers of water walks, and Wyatboat 390 It's not just a rarity, it's a time-tested tool for waterfalls that, if properly maintained, can last for years, and many owners consider this model to be the benchmark of reliability among the available metal vessels of the period.
Why does interest in this particular project not fade away decades after mass production ceased? floatabilityUnlike today's low-end thin metal counterparts, it used a high-quality alloy that could withstand impacts on logs and stones without cracking through. Wyatboat 390 It's still relevant today.
But the potential owner should be very serious about the job, and buying a Vyatka is often about buying a semi-finished product that requires the investment of time and money to bring it to its perfect state, but the result is worth it, because you get it. Unique platform for customizationIt's a choice that's almost impossible to find in the modern small-size boat market, and it's a choice for those who appreciate history and like to craft DIY.
History of creation and design features
This model was developed at the Vyatsko-Polyansk Machinery "Molot", which specialized in complex products, including small arms, and logically, the production of boats was approached with engineering precision, the project was created as a mass vessel for fishermen and hunters who need reliable transport to access large reservoirs, such as the Rybinsk reservoir or Ladoga.
The design of the body is made according to the scheme glittering-boat This allowed the vessel to confidently overcome the wave, which is often a problem for flat-bottomers. The D16 aluminum alloy used in construction was highly durable, which made the vessel resistant to mechanical damage when moored to unequipped shores.
The body dialing system deserves special attention, because the longitudinal and transom frames create a rigid frame that doesn't "play" on the wave as much as lighter structures do. Wyatboat 390 It is often referred to as a tank among small craft, implying its ability to hold the impact of the elements and maintain integrity even in extreme conditions.
It's worth noting that over the years, the design has changed, and early releases may have been different in the configuration of the transom and the location of the handuks, so when looking for a specific modification, it's important to carefully study the photos and documentation to understand which variant. Soviet shipbuilding You have to deal.
Technical specifications and dimensions
To understand the scale of the challenge of operating this boat, you need to look at its passport details in detail, the size of the vessel allows you to comfortably accommodate a crew of three or four people with a full set of equipment, which makes the model versatile for various types of outdoor activities on the water.
Below is a table with the main technical parameters that should be taken into account when calculating the load capacity and choosing a motor:
| Parameter | Meaning |
|---|---|
| Longest length | 3900 mm |
| Body width | 1600 mm |
| Height of board | 450 mm |
| Load capacity | 400 kg |
| Body weight | ~130-140 kg |
As you can see from the data, the weight of the empty boat is substantial, and it's almost impossible to transport yourself on the roof of a passenger car without special equipment or assistance. trailerThis requires additional registration and compliance with traffic rules when towing.
The engine installation usually involves the use of mounted motors with a capacity of 10 to 25 hp Tranets reinforced to withstand vibrations and engine traction, however, when installing powerful modern engines, it is recommended to carry out additional defects in the state of the metal in this area. Old aluminum may have latent fatigue of the metal.
The state of the used market and the evaluation at the purchase
Finding a live specimen in the secondary market can become a quest, with prices ranging from symbolic bags for "buckets with holes" to very serious money for restored samples with a perfect bottom and renovated interior, the main rule being not to believe blindly the seller's assurances about tightness.
When you look, you should pay attention to the condition of the bottom and the zygomatic parts. crack If the boat was on the ground for a long time without support, it could deform, which would lead to difficulties with management and water collection as it moved.
When inspecting the bottom, tap your knuckle on aluminum: a deaf sound may indicate the detachment of the paint or the presence of a thick layer of dirt and corrosion under it, a ringing sound indicates a good condition of the metal.
⚠️ Warning: Never buy a boat without first checking on the water. Even if the seller says "just need to lubricate the joints," it can mean that there is a large hole that you will only find in the middle of the reservoir.
It's also worth checking the completeness. Original seats, keys, rods and even water scoops are often lost over time. Lack of regular elements may require new ones, which will incur additional costs and waste time. Wyatboat 390 It is very valuable in the kit, as it is extremely difficult to find original spare parts.
Restoration and necessary repair of the building
The recovery process often begins with a complete clean-up of old paint, dirt and oxides, which uses sandblasting or brushing, and it is important to identify any hidden defects that may have been masked by layers of bitumen mastic or epoxy by previous owners.
If cracks are found, they need to be welded. The duraluminium alloys that make up the boat require argon welding. Normal electrode welding is not suitable here, because the metal will simply burn out or become brittle at the seam. After welding, the seams are necessarily sanded and checked for leakage.
☑️ Stages of the restoration of the building
Once mechanical damage is repaired, the corrosion protection stage begins, and aluminum is prone to electrochemical corrosion, especially in salt water or in contact with heterogeneous metals. painting It's not just aesthetics, it's also a necessary measure of protection, and it uses special soils for non-ferrous metals and wear-resistant enamel.
Tuning and modernization for comfort
Soviet design is functional, but it's Spartan. Modern comfort requirements dictate their own conditions, so tuning is the best way to do it. Wyatboat 390 Often includes the installation of soft seats, cold knobs and comfortable cans, and the owner can adapt the interior to his needs, whether it is trolling fishing or family picnics.
One of the popular improvements is the installation of windshields, which is often missing or cracked, and the installation of a modern triplex or plexiglass greatly improves the comfort of the control, protecting against splashes and headwinds, and this is especially true when driving on sleeves.
Secrets of modernization of transom
Many owners reinforce the transom with additional sea aluminum linings 5-6 mm thick, which allows you to safely install motors with a capacity of up to 30 hp, exceeding the standard recommendations.
They also change the mounting system of the cans, and the standard jacks can be inconvenient, so they're replaced with modern rotary models, and inside the cockpit you can organize storage spaces for gear by slamming hatches into the deck or installing sealed boxes, which makes the boat a complete complete life. fishing-boat.
Operation and maintenance on water
The boat is predictable and stable in operation, because of the sharp contours of the bow, it cuts the wave well without burrowing its nose, but it is worth remembering the inertia of the aluminum hull: it takes longer and longer to accelerate and stop than light PVC analogues.
Maintenance is mainly about monitoring the condition of the anodic protection (if installed) and the integrity of the paint coating. Regular washing with fresh water after use in salt water is mandatory.
⚠️ Warning: When operating in shallow water, always use a motor position sensor. A screw hitting a rock at speed can damage not only the motor, but also the transom of the boat, transmitting a shock wave to the hull.
Keeping the boat upside down under a canopy or in a garage is best to keep it out of the way. If the boat is standing on the water, you need to clean the fouling regularly and check the bottom. Wyatboat 390 It will not serve a generation of owners.
Wyatboat 390 is a designer for adults, which with a competent approach turns into an unsinkable and reliable platform for any water tasks.
Frequently Asked Questions (FAQ)
What is the maximum speed of the Wyatboat 390?
With a motor of 15-20 hp and one passenger, the boat confidently goes on plane, developing a speed of about 30-35 km / h With a full load, the speed drops to 20-25 km / h, which is a comfortable mode for long-distance crossings.
Do I need to register this boat with GIMS?
Yes, the hull in running order is over 200 kg (even without a motor) and more than 3 meters long. Under current legislation, such a vessel is subject to mandatory registration and requires the right to operate a small vessel.
Is it possible to use a boat in winter?
Aluminum is not afraid of frost, but the metal becomes more brittle at extremely low temperatures. Exploitation is possible, but requires caution when hitting the ice. It is also important to consider that rubber seals and elements can tan in the cold.
Where to find plans for repair or tuning?
Original drawings can be found in the archives of boat-modeling clubs, in specialized powerboating forums or in the Soviet-era technical literature on small-size fleets.
