Choosing a swimming means for fishing or recreation is always a search for a compromise between weight, dimensions in a deflated state and driving qualities. PVC boat with NDNDM The low-pressure inflatable floor was a real breakthrough in the inflatable water transport industry, and unlike the classic plywood models, the bottom is a single inflatable structure, which fundamentally changes the way we operate a vessel.
The main advantage of these boats is the lack of rigid elements in the floor design, which allows you to assemble or inflate the boat in just a few minutes, but despite the apparent simplicity, the market is full of models with different specifications of tissue density, cylinder design and seam quality. NDMA It provides excellent hydrodynamics, but only if the model is chosen for specific tasks.
In this article, we will conduct a detailed analysis to help you avoid getting confused with brands and modifications. floppyness It's critical for safety, how length affects speed, and why, for some tasks, NDND may be better than classics. Read on to figure out which boat will be perfect for you.
⚠️ Warning: Never pump the bottom of the NDND to maximum pressure in hot weather without supervision. When heated in the sun, the pressure inside the closed cells can rise to critical values, leading to rupture of the seams or deformation of the shape.
What is NDNDT and why it changes the rules of the game
abbreviation NDMA It stands for "Low Pressure inflatable floor," and visually, it looks like an inflatable cushion made up of many vertical strands connecting the top and bottom surfaces, a technology known as Drop-Stitch that allows you to create flat, rigid surfaces that can withstand the weight of adults and motors.
The main difference from floorboard boats (plywood or aluminum sheets) is the speed of assembly. You do not have to drag heavy sheets of plywood, wet them in water or waste time connecting locks. inflatable floor It spreads itself as you pump the cylinders, and this is especially valuable for those who value time and mobility.
In addition, the BND provides excellent seaworthinessThe bottom has no hard joints, so the wave is extinguished by the entire surface, rather than hitting the joints of the floorboard. The boat becomes softer on the move, less susceptible to impacts on the water, which reduces the load on the angler's spine during prolonged stay on board.
When choosing a boat with NDND, pay attention to the presence of overpressure valves (automatic or manual), which will save the bottom from blowing up with a bubble on a hot day.
But there are nuances: the hardness of the bottom, although high, is still inferior to a rigid aluminum sheet, and for high-powered engines and high-speed planing, careful selection of a model with a reinforced design is required. Tissue density These boats are usually higher than simple rowing models, which adds weight but guarantees durability.
Criteria of choice: what to look at first
We used a few key parameters to compile the rankings, which could lead to the purchase of an inappropriate vessel, the first and most important criterion. loading capacityPassport and real-world are often different things. For a comfortable fishing trip with two adults and gear, the margin must be at least 30%.
The second criterion is the quality of the seams. In boats with NDNDM, the seams are subjected to tremendous tension. gluing or welding (HF) Welding is more reliable because it eliminates adhesive layering over time, but it requires high-tech equipment and is found in premium brands.
- 🔍 Material density: The optimal indicator for PVC is 750-950 g / sq.m. Less dense material will be lighter, but wear out faster.
- ⚓ Design of cylinders: The presence of a timber around the perimeter is mandatory to protect against abrasion on piers and stones.
- 🚣 transom hanging: To install the motor, the transom must be rigidly fixed, and in BNDM, it is often integrated into an inflatable cylinder, which requires reinforcement.
You also have to pay attention to the number of inflatable compartments. PVC It should have at least three independent cylinders, which ensures that if one compartment is punctured, the vessel will remain afloat and allow safe access to shore.
Top 5 manufacturers: review of market leaders
The inflatable boat market in the CIS has been shaped by several key players who have proven their quality over the years, with Russian brands taking the lead as they are better adapted to our conditions and fishing traditions.
One of the undisputed leaders is the company. FlagshipTheir series of boats with NDND differs in the well-thought-out geometry of cylinders and the use of high-quality Korean PVC. Bottom hardness Flagship models are often higher than competitive ones due to a system of additional stringers or enhanced valve design.
Brand Aqua (formerly known as the "BoatWise") offers a great balance of value, with their NDND boats famous for their wide range of sizes, from single-seater to full-size boats. reinforcement The bottom, which protects against punctures on sharp objects.
Company hunter They often have original solutions, like built-in anchor ducks or handy gear pockets, but when you buy a budget model, you have to be prepared for a little more cloth weight to keep it safe.
| Brand | Type of seam | Guarantee | Feature |
|---|---|---|---|
| Flagship | Glue/Welded | 2 years | High stringency of NDLD |
| Aqua | glue | 1-2 years | Wide range of models |
| hunter | glue | 1 year | Affordable price |
| riviera | glue | 1 year | Enhanced trans trans |
Do not discount the brand and the brand. rivieraThese boats are often chosen for trolling due to the powerful transometers, able to withstand motors of greater power than stated in the basic configuration of their counterparts. Thickness of PVC They often vary depending on the series, which allows you to choose an option for a specific budget.
⚠️ Warning: When buying a boat, be sure to check the date of production of PVC. Material older than 5-7 years can lose elasticity and begin to crack on the folds, even if it visually looks whole.
Comparison: BND vs. floorboard (plywood/aluminum)
The eternal debate of water engines: which is better, classic or innovation? Let's examine the objective pros and cons. plywood It's a time-tested classic. It's cheaper to manufacture, and therefore cheaper to buy. The floor rigidity is absolute, so you can stand on your feet and move around the boat with a powerful motor.
But the way you build a boat is to practice, you have to spread out the heavy sheets, put them in stringers, pump the cylinders, then pump them again, because the floorboards eat up the volume. Boat with NDM It takes 10-15 minutes to assemble, compared to 30-40 minutes for the pay-off.
In terms of performance, the NDND wins on the wave. The absence of rigid joints makes the move softer. But in planing with a heavy engine and full load, a solder boat can show slightly better stability of the course, since the hard bottom is less than a sail and does not deform under load as an inflatable one.
The myth of punctures at the bottom of the NDND
There is a popular belief that NDND is easy to penetrate, and in practice, the density of the bottom tissue (often 1100 g/sq.m.) is much higher than that of cylinders, and it is almost impossible to penetrate such a bottom with a stone or snag during normal operation without extreme effort.
Weight is another important factor. A deflated boat is usually heavier than a flatbed of the same size because of the mass of the inflatable floor itself, and if you plan to carry a boat alone far from the car, this can be a crucial parameter.
Operation and maintenance: extending the life of the boat
So, PVC It's been in the boat for years, and you have to follow simple rules of operation, and after every fishing, especially in salt water or in overgrown water, the boat needs to be washed with fresh water, and the salt and organics destroy the structure of the polyvinyl chloride and the glue seams.
Drying is a must before packaging, and even minimal moisture inside the cover during long-term storage will result in mold that is almost impossible to remove from the fabric. inflatable floor It dries longer than cylinders due to its relief structure, so leave the boat straightened for at least a day.
- 🧼 Wash: Use only soap solution and soft sponge. Aggressive chemistry is prohibited.
- ☀️ Storage: Keep the boat in a dark, dry place at a temperature of -20 to +40 degrees.
- 🔧 Repair: Always have a remix on hand. Small punctures are easier to seal immediately than to look for a leak later.
Winter storage requires special attention. You can't leave the boat in the cold in a deflated state if there is condensation on the fabric - ice crystals can damage the microstructure of PVC. It is better to keep it in a slightly bloated state or tightly folded in heat.
☑️ Preparation for winter storage
Tuning and improvement: how to improve the standard equipment
Factory equipment is often Spartan, and experienced anglers know that for comfort, the boat needs to be reworked, and the first thing to think about is protecting the bottom. Protective mat (sleigh mat) of extruded polypropylene not only protects NDND from abrasion, but also creates a thermal barrier, which is important when fishing in cold water.
The second important element is trans-wheels. For heavy boats with NDL, which are often heavier than soldered boats, being able to roll them to the water without a loading trailer is invaluable. Choose pneumatic tires and metal mounts, plastic ones will quickly fail.
It is also worth considering the installation. fishing-platformThey're harder to attach to the inflatable floor than they are to plywood, but these broad-base models spread the load and don't deform the cylinders, which makes the boat a full-fledged floating office for a spinner.
⚠️ Warning: When installing any additional equipment (echo sounders, fishing rod holders), avoid drilling cylinders or bottom. Use only suction cups or attachments to the hinge beam.
Final verdict: who will fit the boat with NDND
In summary, it can be said that PVC-boat It's a choice of a modern person who values time and comfort, and it's ideal for people who change water bodies often, like to fish alone or together, and don't want to spend half a day on assembly and disassembly.
If your priority is maximum speed, minimum budget or extreme loads with constant boat cruising in hard shoes, you might want to look at the classic with paiola, but for 90% of fans of fishing and recreation on the water, NDNDM will be a more convenient and pleasant option to use.
A boat with NDND is an investment in comfort and assembly speed that pays off from the first trip when you are already sailing while others are still fiddling with plywood.
Choose proven manufacturers, do not skimp on material density and follow the rules of operation, then your boat will serve faithfully for many seasons, giving only positive emotions from communication with water.
The secret to longevity of sutures
Once a season (or every two years) it is recommended to treat the seams with a special air conditioner for PVC. This restores the elasticity of the glue and prevents drying of the material at the joints.
Frequently Asked Questions (FAQ)
Can I put a powerful motor on a boat with NDND?
Yes, you can, but strictly within the limits of the passport power specified by the manufacturer, exceeding the power of the motor will lead to excessive load on the transom and seams, which can cause the structure to collapse at high speed.
How much does the velocity drop on the NDND compared to the hard bottom?
With proper pumping (up to 0.25-0.3 atm), the speed difference is minimal (1-2 km/h). However, if the bottom is underpumped, it begins to work as a sail or anchor, which significantly reduces speed and increases fuel consumption.
Is the NDNDD afraid of sharp stones on the shore?
The bottom of the boats with NDND is made of denser and thicker PVC (often 1100 g/sq.m.) than cylinders. Accidental contact with a stone when pulling to shore, as a rule, is not terrible, but dragging the boat on a rocky bottom is not recommended in any case.
Which pump is best used for NDND?
Any powerful pump (leg, battery electric) is suitable for the initial pumping, however, for the final adjustment of the pressure to operating values (0.25-0.3 atm), be sure to use a pump with a pressure gauge, since it is impossible to determine the desired stiffness by eye.
