Choosing a swimming aid for fishing or resting on the water is often a difficult dilemma, especially when you have to balance comfort, load capacity and cost. In recent years, PVC boats with low-pressure inflatable floors, often referred to as an acronym, have become firmly entrenched in the Russian market. NDMAAmong the many manufacturers and models, a special place is occupied by boats under the common name. altaïrThey attract the attention of boaters with their reliability and thoughtful ergonomics.
The main advantage of these designs is the ability to install stationary floorboards, which significantly increases the rigidity of the bottom compared to the classic inflatable models, which allows you to feel more confident on the wave and allows you to use more powerful outboard motors without the risk of damaging the structure of the cylinders. altaïr popular choice among fans of trolling and long water walks, where the stability of the course is important.
In this article, we will discuss in detail the design features, technical nuances and practical aspects of the operation of these vessels. bottom It's a compromise solution, but it's also a good way to take care of the material so that the boat can last for years, and understanding the model can help you avoid common mistakes when you buy and first launch.
Design features of the Altair series
Series of boats, united by name altaïrIt is based on the proven technology of production of inflatable vessels with rigid elements. NDMA It is a low-pressure inflatable floor that is integrated into the overall design of cylinders, and unlike plywood models, it does not require assembly and disassembly of the floor at each descent, which significantly saves the owner time and effort.
The cylinders of such boats are usually divided into several independent compartments, which guarantees buoyancy even in the case of a puncture of one of them. timber It protects the sides from impacts on the pier, rocks or side of another boat, taking the main load when mooring.
Seam technology
In high-end boats, seams are performed by hot welding, which makes them sealed and does not require additional gluing, unlike cold gluing.
It is important to note the quality of the material used. altaïr The most commonly used five-layer reinforced PVC. This material is resistant to ultraviolet, gasoline, oils and mechanical damage. The density of the fabric usually varies between 750-900 g / m2, which is the optimal balance between the weight of the product and its strength specifications.
Benefits of low pressure inflatable floor
Use of technology BNDT is a game-changing experience, and the main advantage is the speed of assembly: you don't have to carry heavy plywood sheets or aluminum profiles, just pump the cylinders with a compressor or a pump, and the boat is ready to operate, which is especially true for those who go out on the water alone or with minimal assistance.
Stringency is ensured by a system of internal struts (stretches) that connect the upper and lower surfaces of the bottom. When pumped to the working pressure (usually 0.2-0.25 atm), the bottom becomes hard as plywood, but retains elasticity, which improves cushioning on the wave. altair It is more comfortable than the hard-boiled analogues.
- 🚀 Quick assembly: The absence of the need to lay floorboard reduces the time of preparation for the water by 3-4 times.
- 🎒 Compactness: When assembled, the boat takes up less space in the trunk of the car and is easier to transport.
- 🌊 Aerodynamics: A smooth inflatable floor creates less resistance to water and wind when moving.
However, it is worth remembering that the inflatable floor is more sensitive to sharp objects at the bottom of the reservoir than aluminum. Therefore, when approaching the sloping shore or in places with a rocky bottom, it is recommended to be careful or use special protective linings.
Technical specifications and modifications
Model line under the brand altaïr The boats can vary by manufacturer and year of manufacture, but the overall parameters remain similar. Boats are usually produced in length from 2.8 to 4.5 meters, which allows you to choose the option for specific tasks: from a single cruising to a full-fledged family model for trolling.
The capacity of such vessels depends on the volume of cylinders and the number of inflatable compartments. stationary-trans, which can withstand engines with a capacity of up to 15-20 hp This opens up opportunities for speed development up to 30-35 km / h, which is critical for overcoming long distances.
| Parameter | Meaning | Note |
|---|---|---|
| Total length | 290 - 420 cm | Depends on the model. |
| Cockpit width | 120 - 145 cm | Work area |
| Load capacity | 350 - 650 kg | Including passengers |
| Engine power | up to 20 hp | Recommended |
| Weight of kit | 35 - 60 kg | No motor. |
When choosing a specific modification, pay attention to the height of the cylinders. Models with cylinders with a diameter of 36-40 cm provide better germination per wave and a larger internal usable area. narrower models (diameter 30-32 cm) are lighter, but may be less stable when fishermen actively move inside the cockpit.
Operation and care of PVC materials
Durability of the boat altaïr Despite the high strength of modern PVC, the material requires careful treatment, the main enemy is ultraviolet: prolonged exposure to the scorching sun unnecessarily can lead to color burnout and loss of elasticity of the upper layer of tissue.
After every fishing trip, especially in salt water or contaminated water, the boat should be rinsed with fresh water. Salt and silt, when dried, can act as abrasives or cause chemical reactions that destroy the structure of the polymer.
⚠️ Warning: Never keep the boat inflated at extreme temperature changes. Heating the air inside the cylinders in the sun can cause the seams to rupture, and in the cold, PVC becomes brittle.
To clean up contaminants, use a soft sponge and special PVC care products, or a regular soap solution. It is strictly forbidden to use solvents, acetone or chlorine-containing substances, as they can damage the protective layer and make the material sticky.
Comparison with competitors and analogues
There are many analogues on the market, such as boats. Flagship, hunter or Cayman.The series. altaïr It often benefits from more elaborate cylinder geometry, which provides better germination for glides. Competitors often emphasize either maximum cheapness, sacrificing material thickness, or excessive strength, making the boat too heavy.
An important aspect of the comparison is the configuration, and many manufacturers sell "naked" boats, where oars, bags and a pump need to be purchased separately. altaïr Often comes in an extended configuration, including high-quality aluminum paddles with plastic blades, belts for carrying and a backpack bag with a reinforced bottom.
When buying, pay attention to the presence of an air vent valve, which allows you to quickly blow the boat before packing, which is especially important in windy weather.
Price policy also plays a role. altaïr It is positioned in the mid-range segment, offering the specifications of premium boats at an affordable price, this is achieved by optimizing production processes and using materials of domestic production, which are not inferior in quality to imported counterparts.
Tuning and redesign of the boat
Owners often seek to improve their vessels by adding comfort and functionality. altaïr This device makes it much easier to descent a heavy motorized boat to the water and lift it to the shore, eliminating the need to carry heavy weights by hand.
Another useful improvement is the installation rod-holder For models with NDNDM, it is important not to overload the nose so as not to disturb the balance, and it is also common to install soft linings on cans (seats), as standard hard seats can be uncomfortable with prolonged fishing.
- ⚓ Anchor system: installation of a rim bolt on the nose and an anchor leer for convenient parking.
- 💡 Lighting: Installation of LED tapes around the perimeter of the cockpit for night fishing.
- 🛡️ Defense: installation of keel tape or overlays on cylinders for protection against abrasion.
When installing additional equipment, it is important to observe the mounting technology; glue and sealants should be used only on the non-fat surface; any changes to the structure that affect buoyancy or stability should be carried out with caution.
☑️ Pre-season checks
Water safety and GIMS
The operation of any boat requires compliance with safety regulations. altaïrLike any other, it must be equipped with life jackets for the number of passengers, and the presence of an anchor, a scoop and a repair kit is a mandatory minimum for going out on the water, even in good weather.
According to GIMS regulations, small craft weighing up to 200 kg and engine power up to 8 kW (about 10.8 hp) do not require registration. However, if you install a more powerful engine or the total weight of the curb boat exceeds this limit, registration is mandatory. Always carry your boat and motor documents, as well as a boatmaster's license if the engine power requires it.
⚠️ Warning: Exceeding the maximum load capacity specified in the boat's passport is strictly prohibited, which reduces the height of the board above the water and makes the vessel unstable, which can lead to a tipping over in a sudden movement or wave.
Keep an eye on the weather forecast. Inflatable boats, with their high sailing capacity due to bloated cylinders, are very sensitive to side winds, and in stormy weather, getting out on these vessels can be dangerous.
Frequently Asked Questions (FAQ)
How long does a PVC boat last for regular operation?
With proper storage and care, the average lifespan of a quality PVC reinforced boat is 10-15 years, and the key factors are dry storage at room temperature and UV protection.
Can I repair the puncture myself?
Yes, most minor injuries (punctures, cuts up to 3-5 cm) are easily repaired at home with a remix that is part of standard delivery. It is important to use glue and fabric of the same brand as the boat material, or universal polyurethane adhesives.
What pressure should be pumped into the bottom of the NDND?
The working pressure at the bottom of the low pressure is usually 0.2 - 0.25 atmosphere (about 3-4 psi on the pressure gauge). Pumping the bottom above 0.3 atm is not recommended, as this can lead to deformation of the internal slings and bloating of the surface.
What is the difference between NDND and NDND with hard flooring?
In classic BNDD, the hardness is only provided by air pressure and internal bonds. In combined versions, thin sheets of plywood or aluminum can be stacked on top of the inflatable floor for absolute flatness of the surface, but this is rare for this series.
The Altair boat with NDND is an ideal choice for those who appreciate assembly time and comfort on the water, not wanting to sacrifice driving performance and reliability of the design.
