Choosing a boat for fishing or resting on the water is always a search for a balance between comfort, load capacity and mobility. PVC NDND 320 for an outboard motor They've become the gold standard for those who don't want to sacrifice assembly quality for compact transportation, 3.2 meters makes you feel comfortable on the water even with a little excitement, and having a high-pressure inflatable floor (HPD) changes the performance of the car compared to classic pedal models.
Unlike boats with hard plywood or aluminum bottoms, here you get a unique combination of rigidity and cushioning. Inflatable keel and stringers create great hydrodynamics, allowing the vessel to easily get on plane even with the not-so-powerful engines. 320 NDLD One of the most popular segments in the boating market in recent years.
However, despite the similarities, different manufacturers use cylinder diameters from 36 to 42 cm, different fabric density and design solutions of transoms. In this article, we will discuss in detail what to look for when buying, compare specifications and help you choose the perfect boat for your tasks.
Advantages of the design of the BND in the amount of 320
The main feature that highlights NDN The bottom of the tank, which is a total mass, is an integrated inflatable floor system, and unlike removable floorboards, the bottom is part of the cylinder, which eliminates the displacement of the elements during movement. For a size of 3.2 meters, this is critical, because it reduces the total weight of the kit to 35-40 kg, which makes carrying and loading in the car affordable for one person.
In addition, inflatables act as powerful shock absorbers: When hitting a wave or when landing hard on glides, the energy is extinguished by air, rather than transmitted to the body and passengers, this is especially true for models planned for use on fast-flowing rivers or in open reservoirs, where the excitement can be unpredictable.
It's also easy to build, you don't have to spend time laying stringers and fixing floorboards, you just need to spread the cylinders, pump them and fix the transom, and the time to prepare for the launch is reduced by 2-3 times compared to the classic pieols.
When you first pump a boat with NDND, use a pressure gauge to accurately determine the pressure at which the bottom becomes hard. This is usually a range of 0.2-0.4 atm, but the exact value depends on the air temperature and the specific model.
Technical specifications and load capacity
The 320 mm size is often called the "border vessel," and on the one hand, it's still quite compact, and on the other, it already has a buoyancy reserve for two adults and equipment. loading capacity Often differs from data-sheet figures due to the features of the cut and the amount of air used.
Most models in this class have a diameter of 36 cm, which provides good stability. However, there are modifications with an increased diameter of up to 42 cm, which are formally classified as 320, but in terms of internal volume and width of the cockpit closer to the 350th models. When choosing, be sure to pay attention to the width of the cockpit - narrow models may not be comfortable to accommodate two anglers with fishing rods.
Tran of such boats is usually designed for engines up to 5-6 hp This is enough to bring a boat with one or two passengers to plane. Exceeding the recommended power can lead to deformation of the tanner board or tearing off the transom, which is a critical accident on the water.
Below is a comparison table of the specifications of popular models so that you can clearly assess the difference in parameters:
| Model | Length/Broadness (see para. | Diameter of the cylinder (cm) | Kit weight (kg) | Max engine power (hp) |
|---|---|---|---|---|
| Flagship 320 NDLD | 320 / 145 | 36 | 38 | 5 |
| Aqua 320 NPD | 320 / 142 | 36 | 36 | 5 |
| Hunter 320 LKA | 320 / 146 | 42 | 42 | 6 |
| Master 320 BNDT | 320 / 140 | 36 | 35 | 4 |
Choice of motor for boat 320 NDND
Powertrain selection is a science that requires considering the weight of the boat, the number of passengers and the desired speed. For a length of 3.2 meters, the optimal range is considered to be engines from 2.5 to 6 hp. Two-stroke engines in this segment are preferable due to the lower weight, which is critical for transport in the trunk of a passenger car.
Motors with a power of 2-3 hp will allow you to confidently move against the current and get on plane mode with only one person on board. If you plan to regularly exit with a partner or cargo, it is worth considering options with a power of 5-6 hp. They will provide a speed of 20-25 km / h, which is comfortable for most fishing tasks.
When installing the engine, it is important to choose the right height of the transom. For boats with NDNDT, a slightly raised nose is characteristic, so the engine often has to be lowered lower than on the plyol counterparts, so that the daywell does not capture air during turns.
☑️ Checking readiness for the first launch
Materials and durability of PVC
The basis of the durability of your boat is the quality of polyvinyl chloride fabric. In the segment 320 of NDND, the most commonly used material is a density of 750-900 g / m2. The density of 750 g / m2 is the standard for lightweight tourist models, while 900 g / m2 and above indicates increased wear resistance, which is important for rocky shores and frequent use.
The most important parameter is not only density, but also the number of reinforcement layers. Quality fabric has 5-7 layers, which ensures resistance to abrasion and UV radiation. Cheap analogues can have fewer layers, making them vulnerable to contact with snags or sharp stones.
⚠️ Attention: Do not leave a fully pumped boat in direct sunlight for a long time unnecessarily. The air pressure inside the cylinders increases with increasing temperature, which can lead to joints divergence or deformation of the structure.
inflatable floor management and care
The main rule of thumb is never to keep the boat deflated immediately after fishing if it was wet. Moisture left between layers of PVC or in the valves can lead to mold and unpleasant odor, which is difficult to get rid of.
Before packing, be sure to wipe the cylinders with dry rags. Pay special attention to the area of the connection of the bottom with the cylinders, since sand and small debris accumulate most often. Abrasive particles when stored in a compressed state can damage the inner layer of tissue.
Use PVC or a conventional soap solution to clean the polymer, and aggressive chemicals, solvents and gasoline are strictly prohibited, as they destroy the structure of the polymer, making it brittle and dull.
The secret to fast drying
If you don't have time to dry the boat at home, leave it in the garage or on the balcony in straightened form for 2-3 hours, and you can use a blow-out car compressor (if you have one) to remove moisture from hard-to-reach valve areas.
Comparison with solder models
The eternal fishermen's dispute: which is better, NDND or floorboard? Pilled boats have a hard, flat bottom that is easy to walk on, and they tend to be cheaper. However, their assembly takes longer, and the weight of the kit often exceeds 50 kg due to aluminum or plywood sheets.
Boats NDLD 320 They're better at assembling speed, weight and comfort on the wave, and they're softer to the touch, which is important if you plan on sitting on the floor of a boat without chairs, but they also have a disadvantage, which is that they have less rigidity when cruising in shoes with solid soles, although this is rarely a problem for fishing.
If you value time and mobility, the choice of an inflatable floor is obvious. If the priority is maximum floor rigidity for heavy chairs or tables, you may want to consider a soldered or reinforced bottom model.
The boats are ideal for mobile fishing from shore, where every kilogram of weight and minute of assembly time is crucial.
Frequently Asked Questions (FAQ)
Can I install an electric motor on the boat 320 NDND?
Yes, most 320 NDNDMs have a transom designed to fit electric motors. Because electric motors are usually lighter than gasoline and have less traction, they are great for quiet fishing. It is important to make sure that the battery is securely anchored at the bottom, as its weight can shift the center of gravity.
What is the minimum weight of the 320 NDND?
The minimum weight of the kit can reach 32-34 kg depending on the manufacturer and equipment. The lightest models usually have a thinner fabric (750 g / m2) and a minimum number of attachments. However, weight savings should not come at the expense of strength, especially if you plan to walk on rocky shores.
Do I need to lubricate the valves on the NDNDD boat?
Lubricating the valve with oil or fat is not recommended, as this can damage the rubber seals. For sealing and easy rotation, use special silicone lubricants designed for PVC products, or just watch for the purity of the thread and the absence of sand.
Will the boat 320 go to plane with a 3.5 hp engine?
Going out for planing with a 3.5 hp engine is possible, but only with one person of light weight and a minimum amount of equipment. For comfortable operation with a load or two, it is better to consider engines from 5 hp, which are guaranteed to bring the boat to glider mode.
