Choosing a first or new boat for fishing and recreation on the water is always a compromise between cost, size and performance. It is in this niche that the aluminum boat Ob 1, which has become a kind of benchmark for affordable water transport for thousands of Russians, has been firmly established for many years, many fishermen, especially from Siberia and the Volga region, know this model firsthand, since its production was established in Soviet times, and therefore, its reliability has been tested by decades of severe operation.
However, despite its popularity, there are many contradictory opinions around this model, and it is only possible to objectively assess its potential by gathering together real-world views. reviewsSome people praise the boat for its unbeatable hull and powerful engine, while others complain about its rolling and noise, and in this article we will look at the technical details, the real problems in operation, and whether it is worth buying this boat today, so that your decision is balanced and correct.
Before we get into the technical details, the Ob 1 was designed as a mass boat for a wide range of consumers, not as a specialized racing projectile. That's why its design combines simplicity, maintainability and a sufficiently high load capacity for its class. Understanding this philosophy will help you to adjust the craft correctly and avoid the frustrations that often arise from beginners who expect from a budget aluminum boat the qualities of a sea boat.
Design features and geometry of the body
The basis of any boat is its body, and in the case of the Ob 1 model we are dealing with a classic aluminum design made of the AMg5M alloy. corrosion resistance The geometry of the hull is a flat-wheeled bottom with a keel angle of about 10 degrees in the stern, which provides good germination on the wave, but requires careful attention to the weight distribution on board.
Importantly, the boat's contours are designed to provide maximum stability in quiet water, which is critical for fishing. However, in the excitement of more than 30-40 centimeters, the so-called "slap-up" begins, when the bottom of the whole plane hits the crest of the wave. To compensate for this effect, many owners recommend installing transom plates or experimenting with the tilt of the lower unit engine.
⚠️ Note: When operating the boat Ob 1 at speeds above 30 km / h without an installed nose aerodynamic visor (tent), the risk of splashing the cockpit with water is high, which can lead to water scooping and reduced safety.
The interior space is divided into several compartments, including the bow trunk, which, according to many users, could be larger. The bulkheads are made with sufficient tightness, but over time require inspection and possibly additional sealing of the seams. Aluminum 2 mm thick in the bottom and 1.5 mm in the sides withstands serious loads, but when hitting hard ground at a high speed, deformation is still unavoidable, so navigation In shallow water, it must be careful.
Technical details of welded seams
Factory welding is performed by argono-arc method, however, in places of high stress concentration (corners of the transom) microcracks may appear over time, requiring attention during the annual inspection.
Real indicators of seaworthiness and manageability
The seaworthiness of the Ob 1 is often the subject of heated debates on powerboating forums. On the one hand, the boat confidently holds a wave of up to 0.5 meters if you go on the opposite or at an angle, which makes it suitable for large lakes and reservoirs. On the other hand, the associated wave is affected by a short waterline and the lack of pronounced zygomatic rounding, which can cause the boat to start prowling or even swamping.
Manageability is directly dependent on the engine and its location. The regular rampel control is quite tight, especially at high speeds, so experienced owners often switch to remote control (DU), which not only increases comfort, but also allows you to shift the center of gravity, placing the battery and passengers more efficiently. Course stability on planing satisfactory, but requires constant steering in the side wind.
- 🌊 The boat behaves perfectly in quiet water and when fishing in overgrown reed places thanks to the flat bottom.
- 🌬️ In lateral wind sailing is high, and the boat can demolish, requiring constant correction of the course.
- 🔄 The radius of circulation is quite small, which makes it easy to unfold in narrow ducts.
- 🐟 For spinning fishing in standing water, the stability is almost ideal for this class.
And it's also worth mentioning the behavior of the boat when it's fully loaded. Unlike many competitors, Ob 1 doesn't lose much in driving performance when you add 2-3 people and gear, but the stern dispersion becomes noticeable. To get the boat to plane at full load, you often need to use transom plates or adjust the angle of the engine folding. reviews, which advise not to save on engine power, if you plan regular operation with full load.
Operational and fuel consumption
One of the key factors in choosing a boat is its efficiency. Ob 1, due to its relatively low weight (about 140 kg in the basic configuration), allows you to use medium-power engines, which has a positive effect on the owner's budget. The optimal engine is 9.9 hp, which is able to bring a boat with one or two passengers to plane, while consuming a quite moderate amount of fuel.
Real fuel consumption varies depending on loading, bottom condition (fouling) and weather conditions. At a cruising speed of about 25-28 km / h, the 9.9 hp engine consumes about 3-4 liters per hour. If you install a more powerful engine, for example, 15 hp, the consumption will increase slightly when driving in economical mode, but there will be a reserve of traction for difficult conditions.
The table below provides indicative fuel consumption data for different operating modes, based on user statistics:
| Engine power | Loading (kg) | Speed (km/h) | Expenditure (L/hour) | Mode of traffic |
|---|---|---|---|---|
| 9.9 hp | 150 | 22-25 | 3.0 - 3.5 | planing |
| 9.9 hp | 250 | 12-15 | 2.5 - 3.0 | Water-displacement |
| 15 hp | 150 | 35-40 | 4.5 - 5.0 | Full gas. |
| 15 hp | 300 | 28-32 | 4.0 - 4.5 | planing |
We should not forget about others. operating costsThe aluminum case does not require painting every season like steel, and is not afraid of ultraviolet like plastic, which reduces the cost of care. However, transportation on a passenger car trailer requires taking into account the total weight, which with an engine, gasoline and equipment can exceed 400 kg, which imposes restrictions on the choice of tractor.
To reduce fuel consumption, regularly clean the engine’s lower unit and propellers of algae and shells – fouling can increase gasoline consumption by up to 15%.
Comfort, ergonomics and tuning capabilities
The regular equipment Ob 1 is spartan, which opens up wide opportunities for tuning, but initially can shock the unfamiliar user with hard seats and the lack of soft elements. Owners often finalize the interior by installing soft linings, hand-helds instead of hard cans and additional shelves for tackles. ergonomics The cockpit allows three adults to accommodate, although the four of them will be frankly cramped.
The awning is a big deal, and the frame is often criticized for being flimsy and difficult to build, so many people are switching to homemade structures made of PVC pipes or reinforced profiles, and the awning transformer makes the boat a full camping option, allowing them to spend the night on the water, which is highly appreciated by tourists.
- 🛠️ Installing a windscreen significantly increases comfort when driving against the wind.
- 🪑 Replacing regular plywood seats with soft seats with backrests is mandatory for long transitions.
- 🔦 Installation of running lights and navigation lighting is necessary for safety at dusk.
- 🎣 Installation of holders for rods and brackets for sonar makes fishing more convenient.
Sound insulation is an important aspect. Aluminum is a great sound insulation, and motor performance, water splashing can be very tiring, and using self-adhesive vibration insulation materials (vibroplastics, splen) on the bottom and on the sides inside the cockpit does wonders by reducing the overall noise and improving thermal insulation, especially if you're planning to use a boat in cool weather or early mornings.
⚠️ Attention: When installing additional equipment (boxes, shelves) make sure that fasteners do not pass through the side without high-quality sealing, otherwise leaks will become your constant companion.
Typical problems and malfunctions
Like any technology, Ob 1 has its own "diseases" that you need to know about in advance, most often owners face the problem of leaking in the area of the beam and the junction of the bottom with the board, this is due to vibration loads and thermal expansions of the metal, regular inspection and lifting of rivets, as well as the use of quality sealants, avoid serious problems.
Another common complaint is the quality of the factory paint, or lack thereof. If the boat is not painted, the oxidation of aluminum will lead to a whitish coating, which, however, is not terrible for the metal, but spoils the appearance. Some owners prefer to leave the boat unpainted, relying on natural oxide film, while others apply special soils for aluminum.
Among other (frequent) problems are:
- ⚓ Breakage of thread on the fastener of the transom bracket due to vibration of the motor.
- 💧 The water entering the nose funduk through loose hatches during rain.
- 🔩 Unlocking the keys for fun while rowing actively.
- 🌪️ Deformation of the thin metal of the bottom with frequent slaps on the wave at high speed.
Most of these problems don't require complex equipment, a set of tools, a sealant for seams and a little free time to bring the boat to its perfect state, and the main thing is not to ignore minor defects, as they can turn into serious trouble on the water. Repairs The aluminum case is available even in the field, which is a huge plus for travelers.
☑️ Annual preparation for the season
Comparison with competitors and summary
In today's market, the Ob 1 competes with models like Kazanka-M, Voronezh and various plastic counterparts. Compared to Kazanka, the Ob 1 wins in payload and seaworthiness, but loses in planing speed. Plastic boats can be quieter and more beautiful, but they are afraid of hitting ice and rocks, whereas aluminum forgives many more mistakes.
The unique feature of Ob 1 is the combination of low price, high maintainability and the possibility of independent deep modernization, which makes it an ideal designer for amateurs. If you want a buy-and-go boat with the perfect out-of-the-box design, that might not be the best choice, but if you're willing to put in a little bit of work and soul, you'll get a reliable mate for years to come.
To sum up, the Ob 1 is a popular choice that pays off when approached competently, and it is not without its drawbacks, but its strength, spaciousness and low cost outweigh the cons for most fishermen and hunters. Proper preparation, moderate tuning and timely maintenance make this boat a real estate for Russian water bodies.
The Ob 1 is the best boat for those who want to get the maximum functionality for a minimum budget and are not afraid to finalize the boat to their needs.
Frequently Asked Questions (FAQ)
What is the maximum power of the motor to be placed on Ob 1?
The manufacturer recommends motors up to 15 hp, but the reinforced transom allows you to install engines with a capacity of up to 20-25 hp.
Do I need to paint an aluminum boat Ob 1?
You don't have to paint the boat, because aluminum doesn't rust. But painting with elastic paints for aluminum improves the look, reduces algae fouling, and reduces noise a little. If the boat is stored on water, antifouling paint is desirable.
How many people are comfortably accommodated in the boat Ob 1?
Passport capacity is 4 people, but comfortably for fishing or relaxing in the boat accommodates 2-3 adults. the fourth passenger will be a little crowded, especially with equipment and gear, although short-term transportation is possible.
How does Ob 1 behave on the wave?
The boat confidently holds a wave height of 0.5 meters when moving on the oncoming or at an angle. On the associated wave, there is a high risk of yaw. The flat bottom provides good stability in the parking lot, but on the move with heavy chop, there are possible shocks ("slaps"), so you need to select the speed by experience.
