In the world of compact swimming facilities, a model known as Ufa 300The squirrel has been a special feature of aquatics for many years, a type of vessel often mentioned in terms of reliability and simplicity, but today's market requires a detailed analysis of its relevance. Many fishermen and hunters are still looking for blueprints or ready-made solutions based on this classic design, wanting to recreate the time-tested version.
It is worth noting that under the name Ufimka This can be a classic metal flat-bottom, as well as its modern inflatable interpretation of PVC. In this review, we will focus on inflatable versions that inherit the design features of the original, offering mobility and ease of storage. The key feature of this design is a flat bottom, providing maximum stability in shallow water and the possibility of ashore in any conditions.
Why is this model still in demand? The answer lies in the combination of low sailing and high payload relative to size. You don't have to be an experienced boatmaster to operate such a boat, but knowing the nuances of operation will allow it to reach its full potential. Let's take a look at what this vessel is today.
Historical background and evolution of the model
The Ufimka's popularity dates back to the Soviet era, when the Ufa Motors and Production Association began producing light metal boats, designed as a versatile tool for fishing, hunting and household needs in hard-to-reach areas, and was designed as simple as possible: flat bottoms, straight sides and no complex contours.
With the advent of modern materials such as reinforced PVCThe inflatables retained the geometry of the original, but gained the advantages of light weight and deflation, allowing the boat to be transported in the trunk of a passenger car, which was impossible for metal predecessors.
Modern versions often have perimeter inflatable tubes, which improve safety and comfort, but the spirit of Ufimka is utilitarian. It's not superfluous, each element serves a specific purpose, and evolution has gone the way of improving the strength of the seams and the quality of the fabrics used, while maintaining a recognizable silhouette.
Technical specifications and dimensions
Discuss Ufam 300It is important to rely on specific numbers, as the choice of engine and equipment depends on them. The standard length of such a boat is usually about 3 meters, which is the optimal balance between capacity and maneuverability. The width often varies between 1.3-1.4 meters, which provides sufficient stability for two people.
Load capacity is one of the strongest parameters, and because of its flat bottom and bulky cylinders, the boat can carry a significant amount of weight, including passengers, motor and fishing equipment, but do not exceed the recommended limits, as this affects driving performance and safety.
The weight of the boat in running order (without the engine) usually does not exceed 30-35 kg, which allows you to transport it in disassembled form. For comparison, metal counterparts would weigh many times more.
| Parameter | Meaning | Note |
|---|---|---|
| Full length | 300cm | Excluding attachments |
| Full width | 135cm | External dimensions of cylinders |
| Load capacity | 350-400 kg | Including boat weight |
| Passenger capacity | 2 people. | Comfortable for two. |
| Engine power | up to 5 hp | Optimal for a quiet run |
It is important to note that the actual figures may vary depending on the manufacturer and year of manufacture of a particular modification. Always check the product passport. PVC tissue density also plays a role: for such boats, the standard is 750-900 g / m2.
Design features and materials
The basis of durability Ufamki Modern versions are made of multi-layer reinforced polyvinyl chloride, which is resistant to ultraviolet, fuel and lubricants and mechanical damage, and the bottom is often made of denser fabric, sometimes with additional protection against abrasive effects.
The design of cylinders usually involves several independent compartments. This is a critical safety element: if one cylinder is punctured, the boat will remain afloat; the partitions between compartments should be sealed and reliable; valves are used in petal-type valves, which ensure rapid pumping and no etching of air.
The secrets of stitching
Modern boats are assembled hot or cold, and hot gluing is considered more reliable because the materials diffusion, creating a monolithic compound that is virtually impossible to break without damaging the tissue itself.
The tray part where the motor is attached requires special attention, and it must be reinforced with a plywood or metal plate protected from water. The hinged transom It is a common solution for light boats, but it puts additional stress on cylinders when moving, and a rigid transom, which is part of the structure, is preferable for regular use with the motor.
⚠️ Warning: When inspecting the boat before the season, be sure to check the condition of the valves and the presence of microcracks on the folds of the fabric, especially if the boat is stored in a deflated state for a long time.
Operation and assembly on water
Preparation process Ufa 300 The first thing you need to do is to spread the boat on a flat surface, clean it of debris, pump the cylinders to a working pressure of 0.2 atmosphere, pump the cylinders in the sun, which will cause the seams to rupture when the air is heated.
Seats are installed after the cylinders are first pumped, and they need to be securely fixed in the slots or on the anchorages. If you use a hard bottom boat (TBD), it is put in after the side cylinders are pumped, and then the keelson is pumped in, forming a rigid bottom.
☑️ Checklist for descent preparation
It's best to go down from the gently sloping shore, avoiding sharp rocks and shells. You need to pull the boat into the water carefully so you don't damage the bottom. If you're using a motorized boat, make sure that the lower unit is not touching the ground. After you go out, check for leakage and stability under load.
Comparison with competitors and analogues
There are many analogues on the market, such as Kazanka (inflatable performance), frigate or hunterUfimka often wins in price and simplicity of construction, but competitors can offer more modern solutions, such as high-pressure inflatable floor (HPD), which makes the boat more seaworthy but also heavier.
The main advantage of Ufimka is its “unkillability” in the basic configuration, simple forms are easier to repair in the field, while specialized fishing boats can have more rods, sonars and attachments, which is not typical for the classic Ufimka.
Compared to metal boats, PVC is better at noise and safety, it rings when it hits water or tackle, it corroses, it quenches sounds, which is important for fishing, and it doesn't require painting, but it's more durable when it's stored in the open, whereas PVC requires space.
To extend the life of the transom board, cover it with several layers of olive oil or special impregnation for wood, even if it has already been treated by the manufacturer, which will protect against stratification when in contact with water.
Care, storage and minor repairs
And Ufa 300 After every fishing, you have to wash the boat with fresh water, especially if you've been swimming in a salty water body, and the dirt and sand left on the cloth act as an abrasive when folded, grinding the fibers.
Keep the boat in a cool, dry place, away from the heater. The optimum temperature is between -20 and +30 degrees, but sudden changes are undesirable. You need to fold the boat freely, without breaking the fabric in the same places every time. Change the bend lines with each package.
Small punctures are easily repaired with a remix, the surface is cleaned, degreased and sealed with a patch of the same material using a special glue, and it is important to let the glue dry according to the instructions without hastening the process with heating.
⚠️ Warning: Never use conventional household adhesives (superglue, unadjusted shoe moment) to repair PVC, which contain solvents that break down the polymer structure, and after a short time the patch will move away with the piece of fabric.
Proper drying and storage of the boat in straightened or half-blown form significantly prolongs the life of the seams and prevents the appearance of microcracks on the folds.
Questions and Answers (FAQ)
Can I install a 300-horsepower engine on Ufamka?
Technically, it's possible, but it's not recommended by manufacturers, because overpowering the transom will cause overloading, imbalance, and safety problems, and the boat can bury its nose or lose its stability in corners.
Which glue is best for PVC repair?
The best choice is two-component polyurethane adhesives, specially designed for reinforced fabrics, which provide an elastic and water-resistant seam that withstands deformation when inflated.
How long does the glue dry when repairing a boat?
The drying time depends on temperature and humidity. Usually, the primary polymerization takes 12 to 24 hours at room temperature. Full strength is gained in three days. Don't rush to load the patch early.
Do I need to lubricate the valves with silicone?
Yes, periodic lubrication of the valve sealing rubber with silicone lubrication prolongs their life and ensures tightness, and it also prevents sand and dirt from sticking to internal mechanisms.
