Inflatable boats have long since ceased to be just a toy for swimming off the coast and have become full-fledged boats that can compete with rigid hulls. Among all types of designs, a special place is occupied by models with low-pressure inflatable floors, known as the “Shore Bottom” model. NDMAThis technological solution allows you to create comfortable and safe boats that are easy to transport in the trunk of a passenger car.
The main feature of such models is the absence of rigid elements in the construction of the floor. inflatable floor It's formed by cylinders located inside the main circuit, which creates a cushion effect when moving through the water, which makes them an ideal choice for those who value the comfort of landing and the safety of accidentally falling on the deck.
Choosing between a classic pipe boat and a modern inflatable floor option is often a difficult dilemma for beginners. There are many factors to consider, from the type of reservoir and engine power to the weight requirements of the equipment. In this article, we will discuss all aspects of operation in detail so that you can make an informed choice.
⚠️ Attention: NDNDB boats are more sailing because of the rounded bottom. In strong side winds, the control may require more effort than on a rigid hull.
Design features of the inflatable floor
The technology is based on the use of high-strength reinforced fabrics that are able to withstand significant internal pressure without deformation, and the bottom is formed by several independent sections, which provides additional security In the event of damage to one of the chambers, the design is designed to minimize the risk of failure in contact with the rocky bottom.
Unlike hard floorboards, which are assembled from aluminum or plywood slabs, the inflatable floor has no joints and gaps, which prevents water from entering the housing and prevents dirt from accumulating in hard-to-reach places. Tightness It is provided with high-quality welding of seams and the use of reliable valves designed for thousands of pumping cycles.
An important element is a stringer system, which is a rigid profile that is inserted into special pockets along the sides, which gives the boat the necessary rigidity to bend and does not allow the sides to play under the load of the engine. keeliness would not be sufficient to allow for the scoring.
- 🛶 The absence of rigid floor elements increases comfort and safety of operation.
- 🔒 The system of independent inflatable compartments guarantees buoyancy in case of damage.
- ⚓ Built-in stringers provide the necessary rigidity of the structure on the wave.
It's worth noting that the bottom shape of these boats often has a pronounced kilewity, which is formed by the tension of the fabric, which allows you to effectively cut the wave, providing a soft ride. However, this design requires strict adherence to pressure in the cylinders, as the underperforming hull quickly loses its driving qualities.
⚠️ Warning: Do not use electric pumps without auto-stop function for final pumping. Pumping NDNDT cylinders in the sun can cause the seams to rupture due to air expansion.
Advantages and disadvantages of NDLD models
Every technical solution has its strengths and weaknesses, and inflatable keel boats are no exception. comfortYou can walk barefoot on the bottom without fear of splintering or hurting yourself against cold aluminum, which is especially important for family holidays with children or fishing with a dog.
On the other hand, the weight of a ready-to-swim boat can be substantial: an inflatable floor reinforced with stringers and made of dense fabric adds mass compared to simple slate models. Transportation When assembled, it also requires more space, since packing such a boat in a compact backpack is more difficult than the plywood floor option.
But for many users, the benefits are outweighed by the downsides: the ability to quickly assemble a boat without having to dock floor slabs and insert stringers into the grooves saves time and effort, especially when you're out on frequent water trips, when every extra minute of assembly matters.
Analyzing the performance specifications, the following aspects can be distinguished:
- 🚀 Quick access to planing due to the optimal geometry of the bottom.
- 🌊 Excellent germination on the wave and softness of the choppy water.
- 🎒 Dimensions in packaged form can be larger than that of mutuale analogues.
It is important to understand that longevity Although modern fabrics are resistant to ultraviolet light and abrasion, regular contact with sharp objects or improper drying can shorten the life of the product.
Comparison with solder and slate boats
To make an objective assessment of the position of NDND boats on the market, one must compare them to their main competitors: flatbed models with aluminum or plywood floors are traditionally considered faster and better on course, but they lose in weight and complexity of assembly.
Slug boats, where the floor is made of separate slats connected by textiles, are the middle ground in weight, but inferior in comfort. On rigid slats, it is uncomfortable to sit or lie down, and when a strong wave can feel vibration. inflatable floor It is free of these disadvantages, providing a smooth and soft surface.
Let’s consider a comparative table of key specifications of different types of bottom:
| Characterization | NDND (Inflatable) | floorboard (Aluminum) | Slane (Reiki) |
|---|---|---|---|
| Packaging weight | Highly | Medium. | Low. |
| Comfort at the bottom | maximum | Low (cold/slippery) | Medium. |
| Assembly time | Fast. | Long-term | Average |
| Course stability | Good. | Great. | Good. |
As you can see from the comparison, it's a matter of priorities. speed And if you're planning long night fishing or active play with kids, the NDNDB is second to none.
The Hidden Fact About Hydrodynamics
The inflatable floor under the load of the motor flexes slightly, creating the effect of dynamic keeliness, which improves germination per wave compared to a flat hard bottom.
Materials and production technologies
The quality of the boat depends on the materials used, based on polyvinyl chloride (PVC), which can be reinforced or unreinforced. reinforced PVC high density, often using Double Tarpaulin technology.
The elements are connected by hot welding or gluing with two-component polyurethane adhesive, the former being considered more reliable because it creates a monolithic seam that is not susceptible to decomposition over time. Welding technology It allows to withstand pressure up to 250-300 mbar without the risk of structural destruction.
Special attention is paid to protecting the bottom from abrasive wear, and many manufacturers put an extra layer of protective material or use rubber overhead keels, which is critical for putting a boat down on a pebble beach or rocky bottom.
- 🧵 A reinforcement layer of polyester or nylon provides tensile strength.
- ☀️ UV protection prevents the polymer from fading and breaking down in the sun.
- 🧪 Special additives increase resistance to fuel and sea salt.
When choosing, you should pay attention to the density of the tissue, which usually varies from 750 to 1100 g / m2. wear-resistant and less exposure to temperature expansions.
⚠️ Attention: Cheap PVC analogs may contain harmful phthalates and have an unpleasant odor.
inflatable floor management and care
Proper operation significantly extends the life of your boat. The basic rule is not to leave the boat in the sun in a fully pumped state unattended. The air inside the cylinders heats up and expands, which can lead to critical damage. pressure and stitch deformities.
After each trip, especially if it was a sea fishing, the boat must be rinsed with fresh water, the salt aggressively affects the adhesive seams and metal accessories, drying must be done in the shade, in a straightened form, to prevent mold formation inside the fabric.
☑️ Annual maintenance of the boat
Done: 0 / 5Keep the boat in a dry, cool place, preferably in suspension or in a spacious bag, not tightly packed. Crumple in a tight space for a long period can lead to the formation of crevices on the material, which later become points of tension.
Small punctures can be repaired in the field with a remix, but serious damage, especially in the area of seams or stringers, is best entrusted to specialists in the workshop. geometry And the bottom and the driving performance.
To quickly check the leakage, use a soap solution, apply foam to a suspicious area and watch for bubbles when the boat is pumped.
Choice of motor and attachment equipment
Boats with inflatable bottoms require the right engine, and because of the shape of the bottom and the lack of a hard translance (in some lighter models), it is important to comply with the power limit. horsepower It can lead to the destruction of the transom board or loss of control.
Four-stroke engines, which are quieter and more economical, are considered the best choice, but for NDNDM boats, where every kilogram of weight on the transom affects the trim, two-stroke units may be preferred because of their lower weight. Balance between weight and power is key to success.
Remember the anchor system. Inflatable boats, there are cat anchors that don't have sharp horns that can puncture a balloon, and it's also recommended that you use a float anchor cable so that you can pull the anchor from the back of the boat without coming close to the danger zone.
In conclusion, NDND boats are a choice for comfort and safety, ideal for family recreation, diving, fishing in calm waters and where gentleness is important, and proper care and compliance with the rules of operation will make such a boat a faithful assistant for many years to come.
The main advantage of NDND is the combination of the comfort of a hard floor and the safety of an inflatable structure, which makes them a universal choice for recreation.
Frequently Asked Questions (FAQ)
Can I use a NDND boat on a sea wave?
Yes, but with limitations, because they're keel-shaped and inflatable, they're great at holding the wavelength, but it's important to keep the wavelengths in place for a particular model, and you also need to be careful about the pressure in the cylinders, because the seawater is more loaded.
How often should I pump a boat in hot weather?
In hot weather, the air inside the cylinders expands, so the pressure increases, you only need to pump if the boat cools down (for example, after the night) and the pressure drops, the main thing is to put the excess pressure on time to avoid deformation of the seams.
How long does the inflatable floor last when used actively?
With proper care, shade storage and no mechanical damage, high-quality PVC lasts 10-15 years or more, but intensive operation on rocky shores can reduce this time to 5-7 years.
Is it possible to install a sonar on the transom of the NDNDM boat?
Yes, it is possible. There are special mounts for sonar sensors that are mounted on an inflatable transom or on the side, and it is important to use mounts specifically designed for inflatable boats so that the material is not damaged.
