Choosing a swimming aid for fishing or a family holiday on the water is always associated with a compromise between cost, dimensions and driving performance. Hatanga 320 NDLD For several years now, the Novosibirsk-based company BoatWise has been holding a strong position in the segment of low-cost inflatable boats with low-pressure inflatable floors, which attracts the attention of customers with its compact folded form and a sufficiently spacious cockpit for its class.
The main feature of this series is the use of technology. NDMAIt's a hard floor that you can get without plywood sleighs, and it's a lot less weight than the classic sleigh models, and you don't have to waste time tiringly assembling and disassembling the floor, or worry about rotting or swelling. For single fishermen or small companies of two, this boat is often the best solution for carrying gear in the trunk of a car.
However, despite the exterior simplicity, the design has a number of nuances that must be considered before buying. inflatable floor It requires a certain approach to pumping and operating in shallow waters, and the shape of the cylinders affects the behavior of the vessel on the wave. In this article, we will discuss in detail all the technical aspects, the real speed indicators and the durability of materials, so you can make an informed decision.
Design features of the body and materials
The basis of the boat is a five-layer reinforced fabric PVCThe density of the fabric is usually about 750 g/sq.m., which is the standard for this price segment, providing a balance between strength and weight. The seams are made in a brass manner, which ensures the tightness of the joints even during prolonged operation in aggressive aqueous environment.
The key design element is an inflatable floor, which is made up of many cells that, when pumped, create a hard surface, which allows you to kneel while fishing without feeling uncomfortable, unlike stretch bottom models. The cylinders are divided into compartments, which improves safety: if one of the cylinders is punctured, the boat will remain buoyant. quilted, which gives the bottom a profile that improves driving performance and course stability.
To protect against splashes along the perimeter of the cockpit, a hinge beam is installed, which also serves as additional protection when mooring, the bow is reinforced with a rubber bumper buffer, which protects the boat from impacts on the pier or shore. The bow also has a rudder ring for towing or anchoring, and the stern provides comfortable handles for carrying the entire structure.
- 🛡️ Five-layer reinforced PVC fabric of increased density provides durability.
- 📏 Hard inflatable floor (HBB) eliminates the need for plywood slates.
- ⚓ Built-in keelson improves hydrodynamics and stability on the course.
- 💧 The brass seam guarantees 100% tightness in the joints.
Why 5 layers?
The multilayered fabric structure includes a retracting mesh that takes on the tear load, and protective outer layers that are resistant to mechanical damage, which makes the boat less susceptible to cuts on sharp stones or driftwood compared to cheap counterparts.
Technical specifications and dimensions
When choosing a boat, it is critical to match the manufacturer's stated dimensions with real needs. The Model 320 belongs to the class of small boats, which makes it convenient for transportation, but imposes restrictions on the number of passengers and engine power. The length of the hull is 320 cm, but the useful length of the cockpit is much smaller due to the volumetric cylinders.
The width of the boat allows two adults to comfortably accommodate, but the third passenger will already feel constrained, especially when driving actively. Workload in real operating conditions rarely exceeds 250-280 kg to maintain optimal running performance.
The weight of the boat assembled is one of its main trump cards. Due to the absence of heavy sleighs, the kit weighs about 35-38 kg, which allows it to be carried alone for short distances. The diameter of the cylinders inflated provides a sufficient margin of buoyancy, but the high side can sail in strong lateral winds, which requires careful management.
Below is a summary table of the main parameters that will help you quickly navigate the numbers:
| Parameter | Meaning | Unit of measurement |
|---|---|---|
| Total length | 320 | centimeter |
| general width | 143 | centimeter |
| Diameter of the cylinder | 36 | centimeter |
| Load capacity | 400 | kilogram |
| Boat weight | 36 | kilogram |
Driving performance and engine installation
The dynamic specifications of the boat depend on the power of the installed engine and the load. Hatangi 320 It is allowed to install motors with a capacity of up to 5 hp, although the optimal option is the range of 3.5-4 hp When installing a more powerful unit, there is a risk of transom overload and loss of controllability, especially on turns.
On the water, the boat demonstrates a confident exit to planing with one passenger and an engine of 3.5 hp With two passengers, exit to planing mode becomes difficult, and the boat goes into displacement mode. NDMA creates less resistance to water compared to sleigh, but with a strong wave, the effect of "slapping" can be observed if the pressure in the cells is insufficient.
⚠️ Attention: When operating with a motor of more than 3 hp, it is strongly recommended to use a nose bag or cat anchor to shift the center of gravity forward. Without additional load on the nose, the boat can go into a cobra, especially when fully loaded.
Direct-course handling is good because of the keelson design, but sharp steering at high speed is not recommended because of the short length of the hull. For fishing in quiet water or on small reservoirs, these indicators are more than enough. It is important to monitor the uniformity of pumping cylinders, since skewing can lead to the vessel being sideways.
To improve the plane with two passengers, try to shift the battery and fuel tank as far ahead as possible, under the seats, unloading the stern.
Package and ergonomics of the cockpit
The interior space of the boat is organized with the expectation of maximum functionality with minimal dimensions. The standard includes two inflatable seats-banks, which are fixed in special pockets on the sides, this mounting system allows you to easily change their position or completely remove them, making room for large catch or equipment.
The floor in the cockpite is flat, with no protruding elements, which makes it easier to move inside the boat. The surface of the inflatable floor is pleasant to the touch and does not slide even wet, unlike smooth aluminum or plywood. The bow has a runduk compartment, which is often used for storing small things, although it is not a full-fledged sealant because of the design of the valves.
The ergonomics of the landing are rated by users as convenient for short and medium walks. There are no backrests at the seats, so for long transitions it is recommended to use additional accessories or stops. Fastenings for rods and holders for glasses in the basic version are not provided, but can be installed independently if you have tuning skills.
- 🪑 Two inflatable seats with a reliable fixation system in the pockets.
- 🎒 Spacious cockpit with a flat floor without obstacles.
- 🔧 Availability of a remake and a bag for carrying in the basic set.
- 🏗️ Possibility of installation of attachments (echo sounder, holders).
☑️ Checking before getting on the water
Comparison with competitors and modifications
There are many analogues in the market, and Hatanga 320 The main difference is the price and materials used. While competitors can offer thicker fabric (900 g/sq.m), Khatanga benefits from more sophisticated cylinder geometry and quality of joint assembly.
Compared to the model Hatanga 320 NPD (with a stretch bottom), the version of NDND wins in comfort and assembly speed, but loses in weight and price. The stretch bottom is easier and cheaper, but collects water in a double bottom and requires drying, which is not the modification of NDND. For fishing in the cold season or overnight, low pressure inflatable floor is preferable because of the better thermal insulation properties.
There are also larger diameter versions of cylinders, often labeled as "Light" or "Pro" and more load-bearing, but becoming heavier to transport. For most users, the standard version 320 is the middle ground for carrying alone.
⚠️ Attention: Do not use the boat in temperatures below +5°C without first adapting the material. PVC becomes rigid and brittle in the cold, which increases the risk of damage when hitting ice or sharp objects.
The Khatanga 320 NDND wins from competitors due to the balance of price and build quality, but is inferior in maximum load capacity to larger models.
Care, storage and durability
The life of the boat depends on the storage conditions and proper care. After each operation, you need to thoroughly wash the product with fresh water, especially if salt water or water containing sand and silt was used. The sand, getting into the valves and seams, acts as an abrasive, gradually destroying the structure of the material.
Drying the boat should be extended in the shade, avoiding direct sunlight, which can cause uneven drying and deformation of the seams. It is recommended to store the product in a rolled up, but not overstretched state, at room temperature. Long-term storage in a compressed state can lead to the formation of cloth cavities, which eventually turn into cracks.
Regularly checking the pressure in the cylinders is a must. Pumping in hot weather is dangerous with rupture of the seams due to air expansion, and failure to pump leads to deformation of the bottom and reduced driving performance. Use a gauge for control, relying on not only tactile sensations, as the pressure can rise by 15-20% in the sun.
How do you do the right thing?
You have to roll the boat up from the nose, carefully releasing air, so you don't want the seams to fall on each other in the fold, and that will prolong the life of the material.
Frequently Asked Questions (FAQ)
Is it possible to walk in the sea on Khatanga 320 NDND or only on rivers?
The boat is designed to operate in calm waters, rivers, lakes, reservoirs, and open seas only in calm weather and in close proximity to the shore, and its high side and short length make it vulnerable to side waves.
Which glue is better to use for puncture repair?
For repair of PVC fabric, it is recommended to use two-component polyurethane adhesive (for example, 88-NP or specialized adhesives for PVC).
How long does it take to assemble and disassemble a boat?
Because of the lack of sleigh, it takes about 10 to 15 minutes to assemble and 15 to 20 minutes to disassemble, including drying, which is much faster than plywood floor models, where it can take up to 40 minutes to process.
Will the boat withstand the installation of an electric motor?
Yes, electric motors are acceptable and even preferable for quiet fishing, and battery weight should be factored into the overall load capacity, placing it closer to the center or nose for balancing.
