aluminum boat River 355 Considered one of the most affordable and popular options for entering the world of water sports in Russia, the compact model, produced in Nizhny Novgorod, has become a hit due to its low price and simplicity of construction, and many anglers choose it as their first serious purchase, abandoning inflatable PVC analogues in favor of durable metal.
Despite the apparent simplicity, River 355 It has a number of design features that a potential owner should know before buying, not just a piece of aluminum with an engine, but an engineering solution with its pros and cons. In this article, we will discuss in detail the specifications, nuances of assembly and the real experience of operating this model in different conditions.
If you are faced with a choice between a new boat or a new one flat-plateThis material will help to weigh the pros and cons. We will look at how the body behaves on the wave, which motors are best suited and what will be required for self-assembly if you decide to save.
Technical specifications and features of the body
The basis of the design is aluminumThe hull is 3550 mm long and 1390 mm wide, which allows you to transport a boat on the roof of a car or even on the trunk, which is a huge plus for residents of cities without garages.
The hull is designed according to the scheme flat-bottom The boat is 450 mm high, which is sufficient for calm water, but requires caution in the face of extreme excitement, and the hull weighs only 65 kg without equipment, making it one of the lightest in its class.
It is important to note that loading capacity The model is limited to 300 kg, which means that comfortable operation is possible with one or two passengers and a minimum set of equipment, exceeding the load critically affects stability and safety.
⚠️ Warning: Do not overload the boat. When fully loaded (300 kg) River 355 It becomes very rolling, and the spray can easily overwhelm the low side even at a small wave.
To protect against splashes and increase comfort, many owners install tent-cover Aluminum sheets 2 mm thick provide sufficient rigidity but require careful handling when hitting hard objects at high speed.
Package and delivery options
The factory offers several configuration options, allowing flexibility in budgeting. assembly-setIt's a great option for those who know how to work with a tool and want to save money.
The standard set usually includes the body itself, seats (banks), switches and a set of fasteners. The engine and the tiller-motor are usually not included in the basic configuration and are purchased separately. slab-slab And a reinforced transceiver.
- 🛶 Basic kit: Body, 2 removable cans, keys, passport.
- 🔧 Constructor: Aluminum sheets, profile, fastener, instruction (requires assembly and sealing).
- 🚤 Full version: Assembled boat, awning, anchor rods, holders of rods (optional).
When you buy a designer, you get all the necessary details, including: sealant And rivets, and it takes 10 to 20 hours to build, depending on the experience, and it's not only saving money, it's also allowing you to personally monitor the quality of each connection.
☑️ Checking the kit upon receipt
If you're not sure about your own abilities, you'd better choose a fully assembled version. rivet and sealing seams, which is critical for water safety.
Performance and behaviour on the water
On the water. River 355 It's a very good plane machine with a single person and a low-power engine, but when you get more load, you need more power to go into mode, and the optimal speed for economical driving is 15-20 km/h.
Due to the flat bottom, the boat has an excellent stability It's a perfect platform for fishing, where you have to sit still and wait for the cool, but when you go, especially on corners, the roll can be noticeable because of the narrow body.
⚠️ Attention: Flat bottoms are prone to a strong shock load ("slapping") on the wave. River 355 It's very uncomfortable and dangerous.
Many users note the hard drive. To soften the impacts, it is recommended to use balloon (if modified) or special shock absorbers on banks. Windy weather also makes its own adjustments - the sailing of the hull is high.
How do you improve your driving performance?
Installing transom plates (hydrofluoros) on the motor allows you to quickly take the boat to plane and slightly soften the ride, and also helps the proper distribution of cargo: heavy things (battery, anchor) should be shifted closer to the nose or center, avoiding overloading the stern.
Installation may be required to control windy weather keel-redane Or redesign the bow, although it's not normally provided, and it's basically a calm water vessel, moderate rivers, lakes and reservoirs in calm.
Selection of the outboard motor
Choosing the engine is a key moment for River 355The plant recommends engines up to 5 hp, but many put and 6 hp The main limitation is the maximum weight of the engine, which should not exceed 20-25 kg, so as not to overload the transom.
With a 2.5-3.5 hp engine, the boat will confidently hold a plane with one person. For two passengers, at least 4-5 hp will already be required. Electric motors are also popular, but their thrust is often only enough to move in displacement mode.
| Engine power | Number of people | Mode of traffic | Fuel consumption |
|---|---|---|---|
| 2.5 hp | 1 | plane (economy) | ~0.8 l/h |
| 5 hp | 1-2 | plane (max) | ~1.5 l/h |
| 6 hp | 2 | plane (force) | ~1.8 l/h |
| Electric motor | 1 | Water-displacement | - |
When installing the motor, it is important to set the correct deepening Too high will lead to cavitation and loss of traction, too low will lead to increased water resistance, optimally when the plate is level with the bottom or 1-2 cm lower.
When choosing a motor, pay attention to the length of the lower unit. For boats of the River 355 type, the standard length (S) is most often suitable, but it is better to try on the engine before buying or consult with the seller.
Independent Assembly: nuances and tips
If you bought it. build-upThe main task is to ensure that the seams are tight, and this uses a special aluminum sealant and hood rivets, and the quality of the assembly directly affects how long the boat will stay afloat without leaking.
The process starts with the bottom and the sides joining together. pattern (if any) or carefully measure the angles, and the skews in the assembly phase will be almost impossible to correct later.
- 🔨 Tool: Drill, metal drill, rivet, metal scissors.
- 🧴 Expenditure: Aluminum sealant, degreaser, rag.
- 👀 Control: Visually check each seam for no gaps before riveting.
Pay special attention prairieThis is the place that is experiencing maximum vibrational loads from the motor, and it is recommended to use reinforced fasteners and a double layer of sealant, and after assembly, be sure to test in shallow water.
⚠️ Attention: The sealant and aluminum dust must be handled in a ventilated room and with gloves, and chemical components can irritate the skin and airways.
Building yourself can save up to 30 percent of the boat's cost, but it takes time, tools and precision, and riveting errors can lead to leaks that are difficult to repair in operation.
Repair and maintenance of the hull
aluminum AMZ It is not rusting, but it is susceptible to oxidation and galvanic corrosion when it comes into contact with other metals, mechanical damage and electrochemical reactions are the main enemy of the hull, and regular inspection and washing with fresh water after operation in salt water will prolong the life of the boat.
Small dents can be fixed, but with care not to disturb the structure of the metal. ferro-welding or special repair kits for boats PVC and aluminum (cold welding).
Store River 355 Best of all, inverted under a canopy or indoors, direct sunlight is not a threat to metal, but can destroy sealants and rubber seals over time, wintering outside is acceptable, but under an awning.
How often should I check the rivets?
It is recommended to conduct a visual inspection of rivets and seams before each season and after each serious operation, if you notice darkening around the rivets or traces of moisture inside, you need a lift or replacement of the fastener.
Can I paint the boat of River 355?
Yes, you can. To do that, you need to clean, degrease and apply the soil to aluminum, and paint will not only improve the appearance, but also create an additional protective layer, and also hide small scratches.
Will the boat withstand the sonar installation?
And by mounting the sonar sensor on a transom or bottom, it's not going to hurt the body if you use the right sealant when you're mounting it, and many anglers are using navigation and sonar successfully on this model.
What is the real speed with a 5 hp engine?
With one person (80 kg), the speed can reach 25-28 km / h With two passengers, the speed will drop to 18-22 km / h depending on the load and the condition of the bottom (fouling, roughness).
