Choosing a boat for fishing or outdoor activities on the water always begins with determining the requirements for its performance and comfort. PVC NDND RocketThe low-pressure inflatable floor design provides excellent seaworthiness, allowing you to feel confident in the wave, where hard plywood peyol can be uncomfortable.
Many water engines choose this brand due to the thoughtful geometry of cylinders and high-quality materials. Low pressure inflatable floor Not only does it create a soft cushion, it also gives the body a stiffness comparable to the hard-keel models, while keeping the weight assembled, making transportation and descent as easy as possible for even one person.
In this article, we will discuss in detail the design features, advantages of NDNDT technology and nuances of operation that will help you make an informed decision. materialThe stainless materials used in production provide durability, and how to properly prepare the boat for the season so that it lasts for years.
Design features and materials
The basis of any quality boat is the material from which it is made. Rocket five-layer reinforced PVC is used, which has high resistance to abrasion, exposure to fuel and ultraviolet radiation. Tissue density It varies from model to model, but always stays within the range of strength and weight balance, a critical parameter for those planning to use the boat in challenging conditions where the bottom can come into contact with a rocky shore or shell.
The secret of NDT technology
The low-pressure inflatable floor consists of thousands of vertical strands that connect the upper and lower surfaces, and when pumped to the operating pressure (0.2 atm), these strands are pulled, turning the soft shell into a rigid plate that can withstand the weight of passengers and the motor without deformation.
Seams in boats of this type are performed by hot gluing with double gluing, which eliminates the risk of divergence even under extreme loads. Welding technology The seams ensure that they are leakproof throughout their life, making the structure monolithic. It is important to note that all reinforcement elements, such as the piers and cylinder linings, are glued with a margin of safety.
Special attention should be paid to the geometry of cylinders. Rocket It is designed to minimize water resistance and provide maximum stability. Diameter of cylinders It is optimally suited for the declared load capacity, allowing the boat to remain dry even when passing the oncoming wave at high speed, this is achieved due to the high side and the correct shape of the bow.
Benefits of the inflatable floor of the NDND
The main advantage of the models under consideration is the system NDMAUnlike the classic plywood paiola, the inflatable floor doesn't absorb water, it doesn't rot, it doesn't require a complicated drying after each operation, you just flush the air, wipe the surface, and put the boat in a case, which saves you a lot of time and effort, especially if you're out on the pond for a short period of time.
It also provides unrivalled comfort, and you can walk barefoot on the cockpit without fear of splintering or hitting the hard edges of the plywood. Depreciation properties The inflated bottoms reduce the stress on the spine when you move along the wave, and for anglers, this means being able to spend the whole day on the water without fatigue in the legs and back.
Use an electric pump with a pressure gauge to pump the bottom of the NDNDM. This will quickly reach a working pressure of 0.2 atm and eliminate the risk of under-pumping or pumping, which is critical for maintaining the geometry of the housing.
The rigidity of the design with NDND allows you to install outboard motors of greater power without the risk of deformation of the transom. transom board In these models, it's usually reinforced and fixed securely in cylinders, which gives the engine traction evenly to the entire body, which has a positive effect on the speed of planing and fuel efficiency.
Model range and technical specifications
The manufacturer offers a wide range of modifications designed for different operating conditions, from compact double versions to full-fledged four-seater vessels. Each model has its own unique parameters that determine its purpose. Below is a comparative table of popular modifications.
| Model | Length (cm) | Width (cm) | Load capacity (kg) | Weight (kg) |
|---|---|---|---|---|
| Rocket 280 | 280 | 130 | 350 | 26 |
| Missile 320 | 320 | 145 | 450 | 34 |
| Rocket 360 | 360 | 160 | 600 | 42 |
| Missile 390 | 390 | 170 | 750 | 48 |
Choosing a size, you should focus not only on the number of passengers, but also on the amount of equipment. Useful area The cockpit in models with NDND is used most effectively due to the lack of protruding elements of the hard floor, which allows you to comfortably fit even in a boat smaller than the soldering counterparts.
Larger models are characterized by additional options, such as: gear-pocketTranciers in older models are often equipped with transom wheels, which makes it easier to move along the shore, the recommended engine increases in power in proportion to the length of the body, ensuring excellent dynamics.
Completement and ergonomics
The standard equipment usually includes everything you need to start operating. seat However, it is important to carefully consider what is included in a particular shipment, as the configurations may vary depending on the year of manufacture and dealer network.
The ergonomics of the cockpit are thought out to the smallest detail, the seats have soft upholstery and a reliable fastening, which excludes their displacement during movement. Location of the switches It allows you to row with maximum comfort without touching the sides with oars. For those who prefer active fishing, there is the possibility of installing additional accessories, such as rod holders or sonar.
⚠️ Note: Do not exceed the maximum permissible power of the engine specified in the data sheet. Exceeding the limit can lead to the destruction of the transom board and loss of warranty, as well as create a dangerous situation on the water due to loss of controllability.
Packing in a bag is quite compact, despite the volumetric cylinders. Dimensions of packages This allows you to carry a boat in the trunk of most passenger cars, and the weight of the kit is evenly distributed, which makes it easier to carry to the launching site.
Assembly and preparation for launching
The process of assembling a boat with NDM takes only a few minutes and requires no special skills, first of all, you need to spread the cylinders on a flat surface and open all the valves, which will allow the residual air to go out and straighten the tissue.
☑️ Boat assembly procedure
Pumping is made in a certain sequence: first cylinders, then keelson (if any) and lastly bottom. Pressure. in cylinders should be about 0.25-0.3 atm, and in the bottom - strictly 0.2 atm. The use of a pressure gauge is mandatory, since it is impossible to determine the pressure in the NDNDM on the eye, and the under-pumped bottom will lose its driving qualities.
After pumping, it's recommended that you leave the boat in the sun for 10 to 15 minutes, and the air inside the cylinders will warm up and expand, the pressure will rise, and then you need to blow the excess air to the standard values. Temperature expansion It is a natural physical process that cannot be ignored, especially in hot weather.
Operation and maintenance of the boat
The durability of your boat depends on proper care, and after each trip, the boat should be rinsed with fresh water, especially if you have been swimming in salt water or stagnant water with algae. Mud and sandThe stains left on the fabric work as an abrasive and can damage the protective layer when folded.
Store the boat should be in a dry, ventilated room, away from heating devices and direct sunlight. Ultraviolet The best storage temperature is between -20 and +40 degrees Celsius, but it is best to avoid extremes.
Proper drying and storage in the spread or semi-folded form significantly prolong the service life of seams and valves, preventing the formation of microcracks.
Check the valves and the seams regularly, and you can use a soap solution to do that, and if you notice a bubbling, there's a leak that needs to be repaired with a remix. Repairs Small punctures do not require treatment in the service and are easily performed independently in the field.
⚠️ Warning: Never keep the boat fully pumped for long periods (more than 2-3 days) this creates excessive stress on the seams and can cause them to deform or rupture as ambient temperatures change.
Frequently Asked Questions (FAQ)
Can I use a Rocket boat with NDNDM in winter?
The use of PVC boats in winter is possible, but it requires extreme caution. The material in the cold sank and becomes brittle. Puff on You only need to have a boat that's warm and very carefully, avoiding impacts on the ice, and you can't keep it in the cold.
What is the optimal pressure to pump to the bottom of the NDND?
The working pressure for the low-pressure inflatable floor is 0.2 atmospheres (about 3 PSI). Pumping higher makes no sense and even harmful to the construction of heavy, and lower - the bottom will lose stiffness and begin to bend under weight.
Do I need to dry the boat before packing?
Yes, it's a must. If you pack a wet boat, it will cause decay and mold, especially in the seams, and if you can't dry it on the shore, do it at home when you get back, and you'll turn the boat around.
Is the boat compatible with electric motors?
Absolutely. Rocket It allows you to attach both gasoline and electric motors, and for electric motors, this is even preferable because of the lack of vibrations and the lower weight, which has a positive effect on weight distribution.
