Choosing a boat for fishing or family vacations on the water always involves finding a compromise between the carrying capacity, the dimensions in the deflated form and the running specifications. PVC NDND 320 Riviera It has proven itself to be one of the most balanced options for the domestic consumer. Low-pressure inflatable floorIt offers a unique combination of the comfort of hard-deck keel models and the compactness of classic inflatable boats.
Unlike its competitors with plywood paioles, this modification allows you to assemble the case in just a few minutes, without requiring physical effort to lay the floor. NDND Riviera 320 This is often the first major acquisition of a boating that has outgrown the size of a rowing rubber but is not yet ready to operate a heavy boat. In this article, we will discuss in detail the design features, wave behavior and nuances of operation of this popular model.
Importantly, modifications can vary depending on the year of production and the specific manufacturer, as the Riviera brand combines several production lines, but the basic principles of building the hull remain unchanged: reliability, time-tested, and adaptation to the complex conditions of Russian water bodies. inflatable floor Here acts not just an element of comfort, but a full-fledged power element of the design.
Design features and materials of manufacture
The basis of durability of any inflatable boat is the quality of the materials used. Riviera 320 The fabric is used five-layer reinforced PVC fabric, which is highly resistant to abrasion, exposure to fuel and ultraviolet radiation. The density of the fabric is usually 750-900 g / sq. m, which is the optimal indicator for the balance between strength and weight of the product.
The key element of the design is itself high-pressureThis is a separate section, often reinforced with stringers or extra partitions, which gives the bottom a stiffness comparable to plywood, but still allows for compact packaging, and the boats are divided into several independent compartments, which ensures buoyancy even when one of the cylinders is punctured.
An important aspect is the reinforcement system, where the most heavily loaded areas -- the zygomatic parts, the transom, the joints of cylinders -- are glued to additional tapes of the same PVC fabric. Tranza In the boat Riviera 320 is usually removable, made of moisture-resistant plywood and sheathed with plastic or covered with special enamel to protect against moisture.
⚠️ Attention: Pay special attention to the quality of the valves when buying; cheap plastic valves can crack in the cold or in careless handling; prefer metal or reinforced plastic valves such as Swallow's tail.
The hull is assembled using a stringer system (inflatable tubes running along the side inside) or rigid profiles inserted into special pockets, which gives the boat the necessary stiffness to bend and prevents the effect of "hammock" when moving on the planing. NMND construction It implies that the pressure in the bottom should be lower than in the cylinders, which creates a cushioning effect.
Driving qualities and behavior on the water
Conduct Riviera boats 320 NDND It's very different from a hard bottom model, because it's inflatable, it's very scalable, it's very gentle, and it's very light, and it's very low on the water, because it effectively extinguishes vibration and impact, and it makes it ideal for fishing, where you want to be in a boat without back fatigue.
When going into planing with a medium-power (5-6 hp), the boat behaves stably, but has its own specifications. Due to the flexibility of the bottom, there can be a yaw effect at high speeds, especially when side winds or turbulence. Kieliness The bottom of the Riviera 320 is usually average, which allows you to develop a good speed, but requires careful cornering to avoid skidding the stern.
The boat's handling depends on proper loading, and when loading, balancing should be observed: heavy items (battery, anchor, gear) should be placed closer to the center or evenly distributed along the sides. Shifting the center of gravity to the nose can lead to the boat burying in a wave, and to the stern - to reduce speed and deterioration of exchange rate stability.
To improve the course stability at high speeds, try to slightly raise the nose of the boat, moving the load closer to the transom, or use transom wheels with the ability to adjust the angle of inclination of the motor.
On calm water. Riviera 320 It's a very resilient parking lot, which is highly valued by anglers, and it's a very wide cockpit that allows you to move comfortably inside the boat, to kneel, or even to swap places without a critical roll, which is particularly noticeable compared to narrow inflatable can boats.
Assembly, storage and maintenance
One of the main advantages of models with NDMA It's easy to build. It takes 10 to 20 minutes, depending on the owner's experience and the air temperature. Unlike sleigh boats, you don't have to spend time laying out and fixing heavy sheets of plywood. You just have to pump the cylinders, put in stringers (if they're designed) and fix the transom.
☑️ Algorithm of Proper Boat Assembly
After each operation, especially in salt water or polluted water bodies, the boat must be thoroughly washed with fresh water and dried. PVC It does not tolerate long-term storage in a wet and dirty form - this can lead to mold and destruction of the glue layer. The boat should be dried in a straightened form in the shade, avoiding direct sunlight.
To increase the service life, it is recommended to periodically treat the surface of the boat with special means - PVC air conditioners. They restore the elasticity of the material, prevent drying and fading. Particular attention should be paid to the places of gluing and seams, where microcracks most often occur.
⚠️ Warning: Never keep the assembled boat in direct sunlight or near heat sources. The heated air inside the cylinders expands, which can cause seams to rupture or deform the structure.
In winter, it is better to store the boat in a warm room at a temperature not lower than -15 ° C. If this is not possible, you need to use frost-resistant fabrics (they are usually marked by the manufacturer) and avoid mechanical effects on frozen material, which becomes brittle.
Comparison with competitors: Riviera vs Flagman and Admiral
There are many analogues in the market, and a potential buyer often faces a choice between the two. Riviera 320The main difference between the Riviera and the cuts used, for example, the Riviera can offer a wider cockpit due to the peculiarities of balloon inflation, but lose in the stiffness of the transom budget models with a reinforced transom knot.
The flagship in its models of NDND often relies on reinforced cylinders and additional pockets, which increases weight but increases reliability, while the Admiral can win in price, but use a fabric of lower density. Comparative analysis The Riviera occupies a niche of the “golden mean”, offering good build quality at an adequate price.
Below is a table comparing the main technical specifications of the popular Riviera 320 NDNDM model with typical competitors in this dimensional class:
| Characterization | Riviera 320 NDLD | Flagship 320 NDLD | Admiral 320 NDNDM |
|---|---|---|---|
| Length, mm | 3200 | 3200 | 3180 |
| Width, mm | 1450 | 1420 | 1460 |
| Weight, kg | 36-38 | 40-42 | 35-37 |
| Load capacity, kg | 450 | 430 | 440 |
| River. motor, hp. | 5-10 | 5-9.9 | 5-10 |
As can be seen from the table, the differences in dimensions are minimal, but weight can significantly affect the ease of transportation. riviera In this comparison, it looks quite light, which is a plus for single operation.
Equipment and possible tuning
Basic equipment Riviera boats 320 It usually includes seats, pumps, refits and a packing bag, but for full operation owners often resort to additional equipment, a popular improvement is the installation of transom wheels, which greatly facilitate the boat's descent and ashore, especially alone.
For anglers, the installation of holders for rods, sonar and navigator becomes a critical element. Tuning boats It also often involves placing soft pads on benches to enhance comfort during long transitions, and some owners replace standard oars with lighter composite counterparts.
The secrets of tuning Riviera
Many owners install an additional anchor rump on the bow of the boat, as regular may not be enough for reliable fixation, and it is also popular to install a guard railing around the perimeter of the cockpit for the safety of children or when fishing actively.
An important element of modernization is the improvement of the storage system, the installation of sealers or hard drawers fixed on the bottom, allows you to release the cockpit and reduce the risk of loss of equipment. Security It also dictates the installation of additional grip handles and safety leers.
⚠️ Note: When installing additional equipment (echo sounders, navigators), make sure that the wires do not cross the areas of possible friction or pumping of cylinders to avoid damage to the insulation or puncture.
Typical problems and their solution
In the process of operation, owners PVC NDND boats You can face a number of typical problems, the most common of which is the loss of pressure in the cylinders as the temperature changes, which is not a marriage, but a physical property of gases. In hot weather, the pressure increases, and you may need to blow a little air to avoid breaking the seams, and in the cold, the boat may appear "sluggish", which requires pumping.
Another common problem is the unsticking of the transom or reinforcement elements, often due to a breakdown in gluing technology during repair or the use of poor-quality glue, which requires the surfaces to be completely cleaned, degreased and a specialized two-component polyurethane adhesive for PVC.
Wearing valves can also be a problem: if the valve starts to poison the air, it should be twisted out, cleaned of sand and dirt, check the integrity of the rubber seals, if necessary, the valve is easily replaced with a new similar size.
Regularly checking the pressure in the cylinders before each outing is the key to the safety and durability of your Riviera boat.
Timely detection and elimination of minor defects avoids serious breakdowns on the water. Always carry a remake with you, even on short trips, as the situation on the water can change unpredictably.
FAQ: Frequently asked questions
Can I use the Riviera 320 NDND in winter?
Use is possible with precautions. PVC becomes hard in the cold, so you need to collect and pump the ice in a warm room. In the cold, you can not allow impacts on ice or solid objects. You can store ice at negative temperatures, but it is better in warmth.
What is the maximum weight of the engine on the Riviera 320?
The recommended engine power for this model is from 5 to 9.9 hp Installation of a more powerful motor (for example, 15 hp) is possible formally, but can lead to transom overload and imbalance of the boat, which is dangerous.
How long does it take to dry a NDND boat?
Drying time depends on the weather. On a sunny windy day, the boat dries in 2-3 hours. In cloudy weather, the process can take up to 10-12 hours. It is important to make sure that not only the outer surface, but also the areas under the stringers and valves are dry to avoid mold.
How to fix a puncture in the field?
For emergency repairs, use self-adhesive patches from the remix. The surface should be clean and dry. For major repairs at home, you need two-part glue and a degreaser, with a hairdryer heating the gluing site.
