Choosing a swimming aid for fishing or outdoor activities on the water often leads to a dilemma between comfort, speed and portability. NDMAThey're a middle ground, combining the best of classic solder models and lightweight inflaters, and they're designed to be a decent speed, while still being compact enough to transport.
The market today is saturated with offers from dozens of manufacturers, which makes it difficult to find the perfect option. model They deserve attention to how to choose the right power. boat-engine And you'll see why this type of boat has become the standard for many aqueous engines.
It's important to understand that there's no one-size-fits-all solution, because everyone's operating conditions are different, and some people are more interested in planing under full load, and others are more interested in being able to fold the boat into the trunk of the sedan. weighted without costly mistakes.
Design features of the NDND boats
The main feature of these vessels is the design of the bottom itself, which is made in the form of an inflatable cylinder with internal partitions, stretch marks. This engineering solution allows you to create a flat surface that becomes rigid and resistant to deformation when pumped. Unlike the soldering counterparts, there are no metal or wooden sheets, which significantly reduces the weight and build time.
High pressure cylinders forming the sides provide excellent stability Even if one of the compartments is damaged, the boat will remain afloat, although it will lose some of its driving qualities. PVC high density guarantees the durability of the structure even in contact with a rocky bottom or snags.
⚠️ Warning: Never leave a pumped NDND boat in direct sunlight for long periods of time unattended. The air pressure inside the cylinders rises when heated, which can cause the seams to rupture or deform the structure, especially if you pumped it in the morning in cool weather.
An important element is a stringer system, or rigid inserts, which are often included to reinforce the stiffness of the bottom, inserted into special pockets or fixed between cylinders, creating a monolithic platform. gelling Even with two passengers on board.
Size and loading criteria
Determining the optimal size is a balance between the desired capacity and the actual power of your engine. Many beginners make the mistake of buying a boat that is too large for a weak engine, which leads to an inability to go to the plane and increased fuel consumption, or take a too small one, which is unstable in choppy conditions.
When choosing, you should focus not only on the declared load capacity, but also on the usable area of the cockpit. For a comfortable fishing together with a 5-8 hp engine, the best solution will be models with a length of 320 to 360 cm If you plan to use more powerful engines (9.9-15 hp), then you should look at the options from 380 cm and above.
Pay attention to the height of the board. For calm water is enough 38-40 cm, but for large bodies of water, where there is a wave, it is better to choose models with a board of 45-50 cm. This will ensure dryness inside the cockpit and increase safety when moving.
When choosing a size, consider not only the number of people, but also the amount of equipment. If you take a sonar, anchor, tent and fuel supply, add another 30-40 kg to the estimated weight for range and stability.

Power selection of the outboard motor
The right boat-motor bundle determines not only speed but also safety. NDND models are characterized by the possibility of using engines of greater power than flat bottom boats, thanks to better hydrodynamics. categorically not recommended.
Optimal power is calculated based on the length of the hull and the expected load. For three-meter vessels, the “golden mean” is the engines with a capacity of 5-8 horsepower, which allows two adults to plane confidently, while remaining economical and quiet.
The effect of the screw on speed
The diameter and pitch of the screw directly affect the output in the plane. For heavy boats NDND often requires the installation of a screw with a smaller pitch (for example, 5-6 inches instead of the standard 8) so that the engine can spin to working turns and not “choked” at the start.
If you plan to often walk with a full load (three people plus equipment), then it makes sense to consider engines with a capacity of 9.9 hp. or even 15 hp. for models from 360 cm This will provide a thrust reserve and allow you to quickly overcome the oncoming wave.
It's important to remember the length of the lower unit. For boats with a high cylinder, the standard short leg (S) may not be enough, and the screw will capture air on the wave, in such cases it is better to choose long leg (L) motors or use special trench stands.
specifications comparison table
To simplify the selection process, we have prepared a composite table comparing the popular sizes of NDND boats, the data are averaged, since different manufacturers may have small deviations in geometry.
| Length (cm) | Width (cm) | Load capacity (kg) | River motor (L. S.) | Boat weight (kg) |
|---|---|---|---|---|
| 290-300 | 130-140 | 350-400 | 2.5 - 5 | 28-32 |
| 320-330 | 140-150 | 450-500 | 5 - 9.9 | 35-40 |
| 360-370 | 150-160 | 600-700 | 9.9 - 15 | 45-52 |
| 390-400 | 160-170 | 800-900 | 15 - 20 | 55-65 |
And you can see from the table that as you get bigger, not only does the load capacity increase, but the weight of the product itself increases, which is an important factor if you plan to launch the boat alone without using a trailer or a slip.
The main point or important conclusion of this section: When choosing between two adjacent sizes (for example, 330 and 360 cm), always take the model with a margin, if the budget and power of the engine allows, this will give more comfort and safety on the water.
Care, storage and preparation for the season
The durability of your boat depends on how you care for it, and after every trip, especially if you've been swimming in salt water or in muddy rivers, you'll have to rinse the boat with fresh water, and it'll wash away the sand, the silt and the corrosive salts that can destroy the structure. PVC material.
Drying the boat before packing is a must, but it should be done in the shade, completely drying will prevent mold and unpleasant odor, which is very difficult to remove, fold the product carefully, trying not to create sharp cavities in the same places every time.
☑️ Preparation for winter storage
For storage, it is best to use special bags-cofres, which protect against dust and mechanical damage. The temperature in the room should not fall below -10 ° C, as the material becomes fragile in the cold.
⚠️ Warning: Do not use aggressive household chemicals, solvents, gasoline or acetone to clean your NDNDD boat. These substances can eat plastics into the fabric, making it brittle. Use only specialized PVC care products or a weak soap solution.
Frequently Asked Questions (FAQ)
Is it possible to go against the current on a NDND boat?
Yes, you can, but it depends on the engine power and loading. NDND boats have good hydrodynamics, but for confident movement against strong currents and wind, it is desirable to have an engine power reserve of at least 30% of the minimum necessary for planing.
How long does the boat dry after washing?
In sunny dry weather at a temperature of +20 ° C and above, the boat dries for about 2-3 hours. In cloudy or humid weather, the process can take up to 10-12 hours. It is important that not only the outer sides dry, but also the inner cavities of the valves and joints.
Should I pump the NDND boat in the sun?
No, you don't have to pump it, because if you pump the boat in the shade and then you take it out in the sun, the pressure inside will grow on its own, and in hot weather, you'd better even put some air out of the cylinders to avoid overvoltage of the seams.
Are the boats with the bottom of the NDND repairable?
Yes, repairable. Small punctures are sealed with standard PVC remixes. However, if the bottom inflatable cylinder itself (the kylson) is damaged, repairs may require professional intervention in the workshop, as there is high pressure and complex geometry.
