Choosing a boat for fishing or outdoor activities on the water is often a difficult task, requiring a balanced approach to specifications and budget. RodjerIt offers a wide range of inflatable boats, popular for their availability and functionality, and is particularly noteworthy for the series, which is the acronym for NDND, which means inflatable floor with inflatable sides.
This design allows you to achieve the maximum level of comfort, close to rigid housing, while maintaining the mobility of inflatable counterparts. Unlike the classic models with floorboard floor (plywood or aluminum), it uses a system of inflatable tubes that form a rigid and elastic platform, this solution radically changes the experience of driving and being in a boat on the water.
In this article we will consider in detail the design features, advantages and disadvantages, as well as the nuances of the operation of boats. Rodjer You'll learn why this type of design is becoming more popular among fishermen and waterwalkers, and which models to consider first for purchase.
Design features of the NDND series
The main feature of this series is that there are no rigid floor elements, the whole design is based on the use of high-strength PVC material, which is pumped with air to a certain pressure. rigidity The bottom, comparable to plywood, but with a much lower weight and bulk specifications in the assembled form.
The material used for the production is five-layer reinforced PVC, resistant to mechanical damage, exposure to fuel and ultraviolet radiation, the seams are made using hot glue technology, which guarantees absolute tightness and durability of the joints even under intense loads. inflatable tubes are divided into compartments, which improves the safety of operation.
It's important to note that the bottom of these boats is profiled, often with longitudinal redanes or keels, and it's not just a decorative element, but a functional part that provides great performance. hydrodynamics And it's stable at high speeds, and it's better at keeping its trajectory and less prowling when it's turbulent.
What's the secret to stitch strength?
Roger's seams are made by hot vulcanization or gluing with two-part polyurethane glue, which creates a monolithic compound that often exceeds the strength of the material itself, and when used properly, the tearing of the fabric occurs before the seam breaks.
Advantages of inflatable floor before floorboard
The switch to NDND gives the user a number of undeniable advantages that are particularly noticeable during transportation and preparation for launching. The absence of heavy sheets of plywood or aluminum significantly reduces the overall weight of the kit, which is critical for those who go out on the pond alone or use small vehicles.
And it also takes a very short time to assemble and disassemble, so you don't have to put up a floorboard, you don't have to put up a stringer, you fix the floor sheets, you just pump the cylinders, and the boat is ready to go, and it frees up time for fishing or resting, not for tinkering with the parts.
Another important advantage is the increased comfort level, the inflatable floor acts as a shock absorber, smoothing the shocks against the wave and providing a softer landing, and compared to the hard floor, there is no effect of "drummy membrane" and cold from the water, which is especially true in cool weather.
- 🚀 Quick assemblyReady to launch in 10-15 minutes without complex manipulation of the floor.
- ⚖️ LightweightThe absence of heavy elements makes it easy to carry a boat to one person.
- 🌊 Comfort.: A soft bottom reduces fatigue and protects against cold and wave shocks.
- 📦 Compactness: assembled takes up much less space in the trunk of the car.
Use an electric pump with auto-stop function to pump NDND cylinders. This will set the exact pressure and avoid digestion of valves, and also save your energy before fishing.
Review of popular boat models Roger
Manufacturer Rodjer It offers a range of models of different dimensions, each tailored to a specific task, and for single fishing or cruising, compact options up to 3 meters long are great for both, lightweight, maneuverable and fuel efficient with low-power engines.
For more serious tasks, such as trolling or long-distance exits to large bodies of water, models are designed from 3.2 to 3.6 meters long. They have a large buoyancy reserve, reinforced transom and are able to carry more powerful engines.
The most noteworthy modifications are the increased width of the cylinders, which provide additional stability, which allows you to stand confidently on your feet while fishing, and the presence of a reinforced keel and a hump around the perimeter, which protects the sides from impacts on the pier or stones.
Technical specifications and comparison
When choosing a particular model, it is important to pay attention not only to the length, but also to other technical parameters. The load capacity, number of compartments, type of bottom and permissible power of the engine all affect the final behavior of the boat on the water and the safety of the crew.
Below is a comparative table of popular models of the series of NDND, which will help to orient in the range and choose the option that meets your requirements for capacity and power.
| Model | Length, m | Width, m. | Load capacity, kg | Engine power, hp |
|---|---|---|---|---|
| Rodjer 290 NDLD | 2.90 | 1.40 | 400 | 8 |
| Rodjer 320 NDLD | 3.20 | 1.45 | 550 | 12 |
| Rodjer 340 NDLD | 3.40 | 1.50 | 650 | 18 |
| Rodjer 360 NDLD | 3.60 | 1.60 | 750 | 25 |
Keep in mind that the actual passenger capacity is often below the rated carrying capacity if you plan to bring large amounts of heavy equipment, anchor and fuel. Always leave a weight reserve for safety and a comfortable landing.
inflatable floor management and care
Despite the high strength of the material, the inflatable floor requires compliance with certain rules of operation. Before each pumping, you need to clean the installation site of the boat from sharp objects, branches and debris. Using a special protective mat or awning under the bottom will significantly prolong the service life of the product.
It is important to follow the manufacturer's recommended cylinder pressure: insufficient pressure will lead to deformation of shape and reduced driving performance, and excessive pressure will lead to overvoltage of the seams, especially in hot weather. In the sun, the pressure in closed volume increases, so it is better to under-pump the boat on the shore than to pump.
After each operation, the boat must be thoroughly washed with fresh water, removing sand, silt and fish residues, and the product should be stored in a dry, ventilated place, in a straightened or slightly rolled up form, avoiding permanent cavities on the materials.
⚠️ Attention: Never dry a boat with NDNDD in a fully pumped state under direct sunlight on a hot day. The air inside the cylinders expands, which can cause seams to rupture or deformation of the valves.
☑️ Preparation for winter storage
Repair and restoration of leakage
Even the strongest PVC can get damaged by contact with sharp objects or by careless handling. Rodjer It allows self-repair in the field or at home, using kits, or specialized patches and glue.
The repair process involves degreasing the surface, applying glue to both glued surfaces and tightly fixing the patch. It is important to use glue designed specifically for PVC materials, since universal adhesives may not provide the necessary elasticity and strength of the seam.
In case of damage to the inflatable floor (keel or cylinders), the procedure is similar to the repair of the sides. However, it is important to ensure a smooth surface of the patch so that when pumped, it does not create stress points.
⚠️ Attention: When pasting a puncture, do not use adhesive in aerosol cans or superglues (cyanacrylates) which make the material tough and brittle, which will further destroy the tissue around the repair site.
High-quality repair using two-component glue and reinforced fabric restores 100% of the tightness and strength of the product, making the damage site almost invisible during operation.
Final selection recommendations
Boats Rodjer With the design of the BNDT, they represent a great balance between price, comfort and functionality, ideal for those who value mobility and do not want to sacrifice performance, and a well-chosen model will be a reliable assistant for many years to come.
When buying, pay attention to the package: the presence of quality oars, bags, pump and remix often eliminates the need to buy accessories separately.
Keep in mind that water safety depends not only on the quality of the boat, but also on its proper operation: follow the rules of registration in the GIMS, if required for the chosen model, wear life jackets and carefully monitor the weather conditions.
Do I need to register Roger NDND boat in GIMS?
Registration is required if the weight of the equipped boat (with an engine) exceeds 200 kg or if the engine power exceeds 8 hp (10.88 hp according to the new classification). Most Roger models with engines up to 5-8 hp and in light equipment may not require registration, but accurate calculation must be done for a specific set.
What pressure should be in the NDNDB cylinders?
The optimum working pressure is usually 0.2-0.25 kgf/cm2 (about 3-3.5 PSI). The exact values are always indicated on the product passport or on the label next to the valve.
Can I use a NDND boat in winter?
Use is possible, but it requires caution. PVC loses its elasticity in the cold and becomes more fragile. Pumping such a boat in a warm room, and lowering it carefully, avoiding impacts on the ice. Store in the cold is not recommended.
How much is PVC material in Roger's boats?
With proper operation, storage and care, the service life of high-quality reinforced PVC is 10-15 years or more. The main enemies of the material are ultraviolet, fuel and mechanical damage, protection from which prolongs the life of the product.
⚠️ Attention: Do not leave a boat with NDNDH suspended by a transom or on one cylinder in a pumped state for a long time, which leads to deformation of the structure and violation of the geometry of the bottom.
