The modern market of inflatable watercraft offers a huge selection, but it is the PVC NDND 320 It's not just an inflatable boat, it's a complete boat that can withstand the excitement and comfort of standing up, which is not possible with classic models with an inflatable floor, and 320 centimeters is considered a middle ground for two adults with equipment.
The main feature of the design lies in the abbreviation NDMAIt's called "Low Pressure inflatable floor," and unlike the solder floors, it uses a special membrane that creates a rigid flat surface when pumped, so you can forget about assembling and disassembling heavy aluminum floors, making alloy preparation a five-minute exercise.
Despite the obvious advantages, however, this design has its own nuances that you need to know before buying, which can be heavier than plywood-bottomed boats, and the surface itself requires careful handling of sharp objects. Understanding all the technical aspects will help you make the right choice and avoid disappointments on the water.
⚠️ Note: Boats with NDNDM should not be stored in their assembled form for a long time under direct sunlight. The air pressure inside the cylinders and the bottom varies with temperature, which can lead to deformation of the seams or rupture of the material on a hot day.
Design features and advantages of BDND
The main advantage of the model with NDMA It's the speed of assembly. You don't have to carry heavy floorboards and stringers and waste time connecting them, just pump the cylinders and the bottom to the working pressure, and the boat is ready to go down, and this is especially valuable for those who like to go out spontaneously or fish in places where it's difficult to deliver heavy equipment.
The bottom is hardened by a system of internal stretch tapes that connect the upper and lower planes of the membrane. 0.2-0.25 Bar The bottom becomes almost monolithic, and this allows you to stand on your feet, make sharp movements when catching fish, and not be afraid that the structure will bend under weight.
In addition, the low-pressure inflatable floor has excellent thermal insulation properties. Unlike cold plywood aluminum, PVC retains heat, which makes fishing in cool weather more comfortable. It is also worth noting the high maintainability: puncture such a bottom is difficult, and you can seal it even in the field with a remix.
For quick drying of NDNDD after fishing, use a car compressor in blow mode or simply leave the boat upside down in a draft, but not in the sun.
Technical specifications and dimensions
The size of 320 cm implies a length along the outer circuit, whereas the useful length of the cockpit is usually about 230-240 cm The width of such models varies from 140 to 150 cm, which provides excellent stability. 400-500 kgThis allows you to take on board two fishermen, a motor, battery and a stock of gear.
The diameter of the balloon is an important parameter. In quality models, it is 36-40 cm, which provides high side and good protection from splashes. The height of the side also affects sailing: in strong side winds, the boat can demolish, so the presence of a keel or aerodynamic profile of the bottom becomes critical.
The weight of the assembled boat in the transport bag usually ranges from 35-45 kg. This is large enough to be carried alone over long distances, so having a wheel transom or trolley for transportation becomes not just an option, but a necessity. Comparison with the soldering counterparts shows that NDNDM is often heavier by 5-10 kg due to the double layer of PVC in the bottom area.

Choice of motor for boat 320 NDND
The 320 cm long, low-pressure inflatable floor boat has excellent hydrodynamic specifications. The keel, formed by the NDND design, allows you to confidently get on plane even with relatively weak engines. 5-9.9 hp
With a 5 hp engine, the boat will confidently plane with one fisherman and a minimum load. The speed will be about 20-22 km / h If you plan to fish together or with a large supply of equipment, it is better to consider options with a capacity of 8-9.9 hp This will allow you to reach speeds up to 30 km / h and it is easier to overcome the oncoming wave.
When choosing a motor, you should also pay attention to the length of the lower unit. For PVC boats of standard height, short leg (S) engines are usually suitable, but if you plan to install it, you will need to use the engine. wheel-trans or additional add-ons, you may need a long leg (L) so that the screw does not capture air on the wave.
⚠️ Warning: Never use motors of more than 10 hp on 320 NDNDD boats without consulting the manufacturer. Excess power can lead to transomper destruction and a dangerous situation on the water.
Can I use an electric motor on the 320?
Yes, you can. 30-40 lbs (pounds of traction) electric motors are ideal for quiet fishing, lightweight, fuel-free and can maneuver in hard-to-reach areas, but the speed will be lower and the range is limited by battery capacity.
Materials and quality of execution
The durability of the boat depends on the quality of the material used. For models of NDND 320, the standard is a five-layer reinforced PVC The density of at least 850 g/sq.m. Less dense materials (600-750 g/sq.m.) can be used in budget models, but they are more prone to stretching and mechanical damage.
Special attention should be paid to seams. In quality products, the method of gluing the flaps using two-component polyurethane glue is used. This technology provides a tightness and strength of the joint, which is often stronger than the material itself. Cheap analogues can be welded, but for PVC gluing is considered a more reliable method.
Furniture is also important: lictros glued around the perimeter must be securely fixed, and valves (usually of the type "Frog" or "Bravo") must ensure rapid pumping and leakproofness. The presence of linings on cylinders in the points of contact with the switches and the transom extends the life of the product.
The density of PVC 900-1100 g/sq.m. significantly increases the life of the boat, but also adds 5-7 kg to the total weight of the kit.
Installation and additional equipment
The basic equipment of the boat NDND 320 usually includes the boat itself, two inflatable seats (banks), a pump, a remix and a bag-package. However, for full operation this is often not enough, experienced anglers immediately think about upgrading.
One of the most important additions is wheel-treeGiven the weight of the boat, it's very inconvenient to drag it along the shore or on the back, because the wheeled transom allows you to roll the boat like a cart, which makes life much easier, and also a useful addition is an anchor shaft with a cat anchor that folds easily.
For safety and comfort, consider installing safety levers, additional carry handles and rod holders, some of which allow the installation of an awning or a wheelhouse, which turns the boat into a full-fledged camping camp on the water.
☑️ Pre-purchase check
Comparison with solder models
The main question before the buyer is: what to choose, a NDNDD or a classic solder boat? Pied models with a rigid aluminum or plywood floor are cheaper and usually easier, but their assembly time can take 20-30 minutes, whereas NDNDT is collected in 5-10 minutes.
The floor stiffness of the solder models is higher, they are less susceptible to deformation under point load (for example, a sharp heel or tool). But on the wave, the solder boat can rattle, and the joints of the floor sheets eventually begin to creak, and NDND is free of these shortcomings, providing silent movement.
In terms of storage, solder boats are more compact in disassembled form, since the floor can be removed and folded separately. The NDND boat is stored only in assembled form (blown), taking up more space in the trunk, but eliminating the need to assemble a "designer" each time.
Care, storage and operation
For the boat to last long, the 320 must be properly cared for, and after every fishing trip, especially in salt water or muddy waters, the product must be rinsed with fresh water, which will wash away aggressive salts, sand and silt, which can damage the material or clog valves.
Drying is a critical step, and you can't keep a wet boat rolled up, because it'll cause mold, bad smell, and break down the adhesive layer, dry in the shade, open the valves completely, and if you can't, at least wipe the surface with a towel.
Winter storage should be at a plus temperature. PVC in the cold tans and becomes brittle, so any manipulation of the boat (pumping, deflation, movement) at a temperature below -5 ° C is prohibited. The optimal storage temperature is from +5 to +20 ° C in a dry room.
How to properly pump a boat NDND?
Pump the cylinders and bottom in stages. First, pump all compartments to 60-70% of the operating pressure. Leave the boat for 10-15 minutes in the sun (or warm) so that the material warms up and stretches. Then bring the pressure to normal. 0.25 BarDo not pump the boat in the heat, as the pressure inside rises when heated.
What to do if the boat is poisoning the air?
Find the leakage site with a soap solution. If the air comes out from under the valve, try tightening it or replacing the sealing ring. If the case is damaged, degrease the puncture site and glue it with PVC glue. Don't use Moment or superglue - they destroy the material.
Is it possible to fish on the NDND in winter?
You can use a PVC boat in winter, but with caution. The material loses elasticity in the cold. Avoid contact with sharp edges of ice, do not throw heavy objects on the floor, and do not try to fold or dramatically change the position of the boat in negative temperatures.
What is the life of the boat NDND 320?
When operated carefully and properly stored, a high-quality PVC reinforced boat lasts 10-15 years or more. The main enemies are ultraviolet light, improper storage (crushed in the heat) and mechanical damage. Regular inspection of seams and gluing of weakened areas prolong the life of the product.
