Choosing an inflatable boat is always about finding a compromise between mobility, capacity and performance. Hunter 320 Low-pressure inflatable floor (LDPB) is one of the market leaders, a modification that is radically different from the classic hard-floorboard versions, offering a different level of comfort and build.
In this article we will analyze in detail the technical specifications, design features and real capabilities of the boat. NDMA It's not just a marketing shortcut, it's a technology that's changing the way we operate on water, and you're going to see how well this model is suited to trolling, overgrown fishing and long-distance crossings.
Design features of the model with NDND
The main difference is that the main difference between this modification is the absence of rigid inserts of plywood or aluminum at the base of the body. The bottom is a single inflatable structure with internal partitions that form the keel and plane, this solution allows you to significantly reduce the overall weight of the kit, which is critical for fishermen-on foot or owners of small cars.
The cylinders are made of multilayer reinforced PVC, resistant to ultraviolet, gasoline and mechanical damage. Tightness It's double-stitched and high-quality adhesives, and the nose has an inflatable keelson that gives the bottom the profile it needs to go plane even at a modest engine power.
⚠️ Attention: Despite the high strength of the material, the inflatable floor is sensitive to sharp stones and shells in shallow water. When mooring to unequipped shore, always use an anchor shaft or approach with your nose, avoiding touching the bottom with cylinders under load.
The design of the transom deserves special attention, it is reinforced with fiberglass linings and has drain holes closed by corks. transom board It's designed to accommodate motors up to 5 hp, which is the optimal balance for a given body size, and overloading the engine can cause the stern to deform and lose control.
To extend the life of the inflatable floor, use a special valve lubricant and periodically check the pressure with a pressure gauge, especially when air temperature changes.
Technical specifications and dimensions
Boat size grid Hunter 320 Optimized to accommodate two people with a full suite of equipment, the dimensions allow you to feel confident on the wave, while maintaining compactness in the assembled form. Below are the main parameters that should be considered when choosing.
It is important to understand that the dimensions declared by the manufacturer may differ slightly from the actual ones due to the features of the cut and pressure in the cylinders. Load capacity It is distributed evenly, but the center of gravity is shifted to the stern when installing the engine, which requires the correct landing of passengers.
| Parameter | Meaning | Note |
|---|---|---|
| Total length | 320 cm | Including inflatable elements |
| general width | 142 cm | By outer diameter of cylinders |
| Diameter of the cylinder | 36 cm | Boat height above water |
| Weight of kit | 34 kg | No motor or gear. |
| Max, load. | 400 kg | Including the weight of the people and the motor |
The volume of cylinders ensures excellent buoyancy even in the event of damage to one of the compartments. safety The pressure in the cylinders must be maintained in the range of 0.2-0.25 atm to maintain the geometry of the hull.
Performance in water
The behavior of the boat on the water depends on the type of bottom. seaworthiness It's because of the keeliness that comes from the inflated bottom, and it's softer than hard bottoms, because the air cushion absorbs the impacts on the water.
But you have to consider inertia. The inflatable floor has more sailing and friction area against the water than smooth plastic or aluminum. The plane requires the right differentiation. The motor has to pull the boat, not push it nose-up.
- 🚤 Manageability: The boat is responsive to the roaming of the roamer, but has a tendency to yaw at a high wave when loaded incorrectly.
- 🌊 cruising: On calm water shows good speed indicators, but on the oncoming wave the speed has to be reset to avoid blows with the nose.
- ⚓ Stability: The wide body provides stability when fishing standing or when actively moving inside the cockpit.
With electric motors, this model is the best, and the silent stroke allows you to sneak up on the fish, and the buoyancy margin allows you to install heavy batteries on the stern without the risk of overturning. Hunter 320 Often chosen as a platform for trolling fishing in small water bodies.
⚠️ Attention: When you move against a wave at high speed, watch the angle of the trim. Excessive nose-scratching can lead to the boat tipping overboard or splashing the cockpit.
Assembly and preparation for exit
The process of assembling a boat with NDND takes longer than pumping a model with a hard floorboard, but requires less physical effort to carry weights. You do not need to carry heavy floor slabs - everything is collected on water or on soft ground.
The first thing you do is you decompose and inflate the bottom, and this is a critical step, because the shape of the bottom is what determines all the geometry, and then you install cylinders that are fixed in slots or slings, and you complete the process with the slingboard and the inflatable keel.
☑️ Boat assembly algorithm
Using a foot pump or compressor greatly speeds up the process. The hand-held frog pump may not be efficient enough to create the required pressure in the bulky bottom of the BND. Pressure control It is a must before each exit, as it can grow to critical values in the sun.
The secret to fast assembly
Inflate the bottom not all at once, let it spread, then get the pressure, and this will prevent distortion and make it easier to install the on-board cylinders in the slots.
Transport and storage
One of the main advantages of the model is its transportability: when assembled, the boat fits in a bag that can be carried in the trunk of a compact sedan or even on public transport (in a case), weighing 34 kg, allows you to carry it to one person, although it is more convenient to do it together.
Storage of PVC materials requires compliance with the temperature regime. You can not leave the boat in the cold or in direct sunlight in a rolled-up form. Polyvinyl chloride at low temperatures it becomes brittle, and at high temperatures it can deform under its own weight.
- 🏠 Garage: An ideal place for storage, where temperature changes and rodent access are excluded.
- 📦 Apartment: It is permissible to store in the pantry, but necessarily in straightened form or loosely folded to avoid clamps.
- ❄️ Winter: Before winter storage, the boat must be thoroughly washed, dried and treated with a preservative composition.
Regular maintenance prolongs the life of the product. Check the valves for contamination, lubricate them with silicone, and inspect the seams for bundles. Repairs Small punctures are easily made at home with the help of a remplekt.
Comparison with peers and competitors
There are many analogues on the market, such as Flagship, hunter (other series) or PoseidonHunter 320 NDND stands out among them for its balance of value and quality. Cheaper counterparts often sin with the quality of the adhesive and thickness of the PVC, and premium brands can be overpriced for a novice boater.
The key factor in the comparison is the type of bottom: hard floorboard gives a more stable platform for fishing, but loses in weight and assembly speed. NDNDM wins in shallow terrain and comfort on the wave, but requires more careful preparation.
The choice between NDND and floorboard is the choice between the comfort of assembly/transportation and the rigidity of the work platform. NDND is often preferred for fishing because of the softness of the floor.
Long-term, it's a reliable 5-7-year active maintenance model, and it's versatile, for family walks, for serious fishing, and for hunting.
⚠️ Warning: Do not use abrasive cleaning agents and solvents to wash the boat. This destroys the PVC protective layer and results in loss of color and strength of the material.
FAQ: Frequently asked questions
Can I put on Hunter 320 NDND motor more powerful than 5 hp?
Technically, it is possible to install, but the manufacturer does not recommend exceeding the power of 5 hp This is due to the design of the transom and the overall load capacity. Excess power can lead to the destruction of the transom board and loss of handling, which is life-threatening.
What pressure should be pumped into the bottom of the NDND?
The optimum operating pressure for the inflatable floor is 0.2-0.25 atmospheres (kgf/cm2). Pumping the bottom above 0.3 atm is not recommended to avoid rupture of internal bulkheads, especially in hot weather.
Will the boat fit into the trunk of the sedan?
The dimensions of the bag with the boat Hunter 320 are usually about 110x40x40 cm However, it is better to clarify the exact dimensions of the package from the seller and measure your trunk, as the equipment (the presence of a bag for the engine, anchor) can vary.
Do I need to clean the stitches after buying?
Special lubrication for seams is not required if the boat is new and has no defects, but once a season it is useful to treat PVC material with a protective spray (type "anti-UV") to aging the plastic and maintain its elasticity.
