Choosing a reliable fishing boat or a family holiday on the water always involves finding a balance between cost, quality of materials and operational capabilities. In the light alloy metal small craft segment, models designed to meet harsh operating conditions are a special feature. Riviera 3400 SK, which during its production has established itself as one of the most affordable and practical options for beginners.
This model attracts attention not only for its affordable price, but also for its well-designed hull, which allows you to feel confident on the wave. Many owners note that for a boat of this size it has surprisingly good seaworthiness. However, before buying a potential buyer needs to understand all the nuances, from the type of alloy to compatibility with various engines.
In this article, we will discuss in detail all aspects of the operation of this boat, consider the real speed and fuel consumption indicators, as well as touch on modernization issues. Riviera 3400 SK It remains in demand in the market even years after the start of production, and whether it is worth considering it as the main option for purchase in the current season.
Structural features and materials of the bodyThe basis of reliability of any small vessel is the material from which its hull is made. Riviera 3400 SK Aluminum-magnesium aircraft alloy is used, most often of the AMg5M grade. This material has high corrosion resistance, which is critical for use in salt water or aggressive environments. The bottom thickness is 3 mm, which provides protection against impacts on small stones and driftwood, and the sides are made of a sheet 2 mm thick.
The design of the body is made according to the "monoblock" scheme with welded zygomatic stringers, which significantly increases the rigidity of the structure. Bones This is a longitudinal stiffness rib that dampens the shock wave when the boat enters the wave, which avoids the flat-bottom splashing effect of water, and makes the movement smoother. forepicIt is not only used for storage, but also serves as an additional buoyancy compartment.
⚠️ Attention: Despite the use of corrosion-resistant alloy, welds and fittings require regular inspection. Neglect of corrosion-resistant drilling can lead to electrochemical corrosion.
An important element of the design is the transom, which is reinforced and designed to install outboard motors up to 30 hp (although many put more powerful ones), the angle of keeliness on the transom is about 10-12 degrees, which is a compromise between seaworthiness and sleeving at low power. The interior space of the cockpit is divided into compartments, which positively affects the unsinkability of the vessel in emergency situations.
Technical specifications and dimensionsWhen choosing a boat, overall dimensions play a crucial role, especially if you plan to transport it on a trailer or store it in a garage. Riviera 3400 SK It is a compact boat class, making it convenient for transport on the roof of a passenger car (if there are appropriate fasteners) or on a light trailer. Below is a detailed table of the main technical parameters of the vessel.
| Parameter | Meaning |
|---|---|
| Maximum length | 3400 mm |
| maximum width | 1450 mm |
| Height on midship | 450 mm |
| Load capacity | 400 kg |
| Passenger capacity | 3 people |
The dry weight of the hull is about 70-75 kg, which allows one person to easily remove the boat from the trailer if there is appropriate equipment (for example, winches or roller supports). Load capacity 400 kg is a formal limit, but in practice the boat carries three adults with a minimum supply of equipment, exceeding this limit leads to a significant decrease in speed and deterioration of handling.
It is worth noting that the actual figures may vary slightly depending on the year of release and the specific modification, for example, earlier versions may have slightly different weighting.
Performance and driving specificationsDriving performance Riviera 3400 SK With a 5-6 hp engine, the boat enters planing mode with only one person on board, reaching a speed of about 20-22 km / h. This is an economical option for quiet fishing, where high speed travel is not required.
When you install a 15-20 hp engine, the performance changes dramatically, and the boat confidently goes into planing even with two passengers, reaching a speed of 35-40 km / h. squirrel-bottom It allows you to confidently hold the wave height up to 0.5 meters, although on a larger excitement comfort is significantly reduced due to the short length of the body, while fuel consumption remains within reasonable limits.
To save fuel and increase speed, it is recommended to accurately set the angle of the trim of the transom plate (or the engine itself).
⚠️ Attention: Installation of a motor with a power of more than 30 hp is not recommended without reworking the transom. Excessive power can lead to tweezing (buried nose in the wave) and loss of control.
The boat's handling is rated as good for its size, the steering wheel responds clearly, the circulation radius is small, but it's worth considering that when fully loaded and driven against the wind, the hull's sailing can make its own adjustments, and in such conditions, it's important to properly distribute the load, shifting the center of gravity closer to the nose.
Comfort and ergonomics of the cockpitInterior space The 3400 SC is designed with a focus on functionality, the floor of the cockpit is riffled, which prevents slipping even in wet shoes, this is especially true when fishing, where there may be scales or mucus on the floor, and the sides have rundooks that can be used to store gear, anchors or personal belongings.
The seats in the basic configuration can be rigid, made of the same aluminum alloy, but many owners immediately upgrade this unit, installing soft overhead cushions or buying removable chairs on legs. ergonomics The location of the cans allows you to sit face to the motor or back to it, depending on the situation.
Features of winter storage
When putting the boat for winter storage, it is recommended to remove all removable elements, wash the cockpit with fresh water and leave the hatches open for ventilation to avoid condensation inside the closed volumes.
For anglers, the ability to install rod holders and sonar is an important element. The design of the sides makes it easy to mount additional tuning without breaking the tightness of the hull, using a sealant and the correct drilling technology. In the bow, as mentioned earlier, there is a closed forepic, accessed through the hatch.
Compatibility with motors and recommendations for selectionChoosing a motor for Riviera 3400 SK The best option for many experienced water engineers is two-stroke engines with a capacity of 9.9 hp with the ability to stretch up to 15 hp. These engines provide excellent dynamics and remain quite light.
Four-stroke engines are also great for this boat, especially if the priority is quiet operation and economy. However, their weight can be critical for a boat with a carrying capacity of 400 kg. When choosing a four-stroke 10-15 hp should be carefully monitored the total weight of the crew.
- 🚤 5-6 hp - Budget option for quiet fishing in calm, low fuel consumption.
- 🚤 9.9-15 hp - "Golden mean", confident planing with 1-2 passengers, versatility.
- 🚤 20-25 hp - for lovers of speed, access to plane with full load, but increased consumption.
When installing the engine, it is important to follow the manufacturer's recommendations on the height of the suspension. For this model, the optimal position is considered when the anti-cavitation plate is 20-30 mm below the bottom plane, which will ensure the best intake of water for cooling and efficient operation of the screw.
☑️ Checking before getting on the water
Tuning and improvement DIYLike any budget boat, Riviera 3400 SK It's a very frequent tuning experience, and owners are looking to improve comfort and functionality, and one of the most popular modifications is the installation of windshields, which not only protects against splashes and wind, but also visually enlarges the boat, making it look like a more expensive model.
Another common modification is the installation of additional knobs and shelves. Because aluminum is easily processed, many craftsmen boil or rivet additional designs to accommodate navigation electronics or fishing boxes, and the installation of soft linings on boards and cans is also popular.
Some owners go further and install stationary fuel tanks instead of regular outboard ones, slam drain valves into the lowest point of the transom for quick pumping of water. tuning It allows you to adapt the boat to specific tasks, whether it is trolling, hunting or family walks.
Competent tuning can turn a simple "Kazanka" into a comfortable boat, but any welding work should be carried out by specialists familiar with the technology of welding aluminum-magnesium alloys.
Frequently Asked Questions (FAQ)
Can the 3400 SK Riviera be used at sea?
Use at sea is only possible in coastal areas and in calm weather, because of the short length of the hull and the relatively low side, going to the open sea or on a large wave is dangerous, the boat is not designed for marine storm conditions.
Which screw is better to put for fishing?
For fishing, where thrust is important, not maximum speed, it is recommended to use screws with a smaller pitch (for example, 6-7 inches for engines up to 10 hp). This will allow you to quickly go to plane with full load and reduce the load on the engine.
Do I need to register this boat with GIMS?
Yes, the weight of the hull 70-75 kg plus the weight of the engine (even the lightest) exceed 200 kg. According to Russian legislation, boats weighing more than 200 kg are subject to mandatory registration. Also, the presence of a motor with a capacity of more than 5 hp (or 8 hp depending on the interpretations and year, but for 3400 SC the engine is usually more powerful) requires rights to drive.
What is the maximum speed of the boat?
With a 15 hp engine and one driver, the speed can reach 40-42 km / h With a full load (3 people), the speed drops to 30-32 km / h. The maximum speed depends on many factors: the state of the bottom, type of screw, wind and wave.
