Properly assembling an inflatable boat is not just a matter of convenience, but a critical factor in water safety and durability. Many beginners underestimate the importance of sequencing, starting with pumping cylinders or installing a transom too early, which can lead to a skewed design, and errors at this stage often cause seams to rupture or deform the bottom on the first step.
Modern models from reinforced PVC The body, which is not properly assembled, can lead under load, making the vessel dangerous to operate, and in this article we will discuss a detailed algorithm of actions that will help you avoid common mistakes and prepare the boat for sailing in minutes.
Selection of location and preparation for assembly
The first step is to choose the right place to deploy the boat, and the ideal option is a flat surface without sharp objects, branches or stones that can damage the boat. cylinders Asphalt, concrete or rolled soil are best, but if you're out in nature, clean the land thoroughly.
It is important to consider weather conditions, especially if assembly takes place on a hot summer day. Direct sunlight can lead to uneven expansion of air inside the cylinders, which creates excessive pressure. In such cases, it is recommended to assemble the boat in the shade or cover the already inflated parts with an awning while the remaining elements are installed.
⚠️ Warning: Never leave a partially inflated boat under direct sunlight unattended - a sharp jump in air temperature inside cylinders can cause seams to rupture.
Before you start, you need to spread the boat down and completely straighten all the folds, so you can visually assess the integrity of the material and make sure that you can make sure that you can do this. cross-plate If the boat has just been removed from a cold room, let it lie at room temperature for about 15-20 minutes to restore PVC elasticity.
Canister pumping procedure and valve system
The pumping technology depends on the type of valves you have installed on your model. LiquiLock Before using a foot or electric pump, make sure that the hose is free of moisture and dust that can clog the mechanism.
The pumping process always starts at the bow compartments, then proceeds to the side compartments and ends with the aft compartments, and this sequence ensures that the geometry of the shell is properly formed, so you don't need to bring the pressure to the working value immediately, because the cylinders are filled by about 70-80% at first.
- 🎈 Check the position of the valve lobe: for pumping it must be in the upper (closed) position so that the air does not leave when changing the pump.
- ⚓ Watch the air temperature: if you rock the boat in a cool garage, and you will swim in the sun, do not pump the cylinders to the stop.
- 🔧 Use a pressure gauge: pressure control is mandatory, as the touch to determine the excess pressure in the PVC It's hard.
After the initial pumping, you have to leave the boat for 10-15 minutes to shrink the material. PVC has the ability to stretch, so the pressure will inevitably fall, and only after that, the final pumping to the values indicated in the product passport is made.
Installation of floorboards (collection floor)
Floor installation is the most time-consuming step, requiring physical strength and coordination. Prefabricated floors (floorboards) made of moisture-resistant plywood or aluminum create a rigid framework that distributes the load, and you start from the bow, sequentially stacking the sections in inflatable tubes.
It is important to ensure that the edges of the floorboards do not pick up or rest against the sides at a sharp angle, as this creates a point of critical tension. tapeIt helps to pull the structure and align the plane.
⚠️ Warning: Do not force the last section of the floor if it does not stand in place – this means that the cylinders are not inflated enough or the previous sections lie unevenly.
When all the sections are stacked, you need to walk through the joints and make sure that the lock joints (profiles) are snapped along the entire length. A characteristic click or tight fit indicates the correct assembly. If the floor is "cruising" or has bumps, the laying procedure will have to be repeated.
☑️ Checklist for the installation of floorboards
Installation of the transone and formation of the cockpit
The traverse (transboard) is the stern bearing element on which the motor is attached, and is installed last when the cylinders are already in their basic shape but not yet fully pumped, allowing the board to be inserted into special pockets without undue effort.
When installing a transom, it is important to observe the verticality of the installation, even a few degrees of distortion will cause the boat to prowl on the course, and the engine will operate with increased vibration. Make sure that the stringers (inflatable tubes on the sides) symmetrically cover the side wings of the transom board.
Once the transom is installed, all compartments are finally pumped to working pressure, at which point the boat finally takes shape and the floor is straightened out, becoming rigid and even. seating (can) and other attachments.
Table of working pressure for different temperatures
Correct cylinder pressure has a direct impact on driving performance and safety. Below are the approximate values, but always prioritize the manufacturer of your particular model.
| Air temperature | Pressure in cylinders (psi) | Pressure in cylinders (kPa) | Valve condition |
|---|---|---|---|
| +15...+20°C | 3.5 - 4.0 | 240 - 275 | Closed (depressed) |
| +25...+30°C | 3.0 - 3.5 | 200 - 240 | Closed (depressed) |
| Below +10°C | 4.0 - 4.5 | 275 - 310 | Closed (depressed) |
| Transportation | 2.5 - 3.0 | 170 - 200 | Closed (depressed) |
Why does blood pressure drop at night?
During the day, the air in the cylinders heats up from the sun and expands, creating high pressure. At night, when cooled, the pressure drops. This is a physical law, not a sign of puncture. Always check the pressure in the morning before going out on the water.
Optimal pressure ensures the rigidity of the housing and prevents the cylinders from collapsing when loaded on corners.
Fixing of attachments and inspection
The final assembly phase involves the installation of switches, spinning holders, sonar and navigation. timber-bar It is important not to overload one side by distributing the weight of the equipment symmetrically relative to the diametrical plane.
Make sure to check the mounting reliability of all the components. Pull the seats, wobble the transom - nothing should fall overboard or shift. Pay special attention to mounting the safety tack for the engine, which will prevent the loss of the engine in the event of its falling overboard.
- 🛶 Fix the anchor tiles in the nose so that they don’t get tangled under your feet.
- 🔋 Install the battery in a special sealed box if you plan to use an electric motor.
- 📡 Place the sonar sensor so that when moving it does not beat against the water surface.
Before you get on the water, go around the boat again, see if you've forgotten any tools inside the cockpit, and the boat should look symmetrical, without skewing or bloating.
Frequent errors in assembly
One of the most common mistakes is to ignore the manufacturer's instructions, and the design of boats of different brands can be very different, for example, trying to insert a transom before the floor is completely spread can lead to damage. bulkheads.
It is also common to use inappropriate lubricants to facilitate the assembly of floorboards. It is strictly forbidden to use petroleum products (gasoline, kerosene, engine oil) for lubricating floor locks or valves.Because they break down PVC and glue, you can only use soap solution or specialized silicone lubricant.
⚠️ Warning: Do not keep the assembled boat in the sun or cold for long periods of time.
Remember that quality assembly takes time. Take your time, especially if you are doing it for the first time or changing operating conditions (for example, switching from cold water to warm water), Patience and adherence to technology are the key to the long service of your vessel.
To make floorboards easier to insert into the boat, sprinkle them slightly with talc or use a soap solution on the lock joints - this will reduce friction on the PVC fabric.
Do I have to completely lower the boat after every fishing trip?
If the boat is stored in a garage or in a country house in assembled form, you do not need to completely deflate the air. It is enough to reduce the pressure to 1.5-2 psi to compensate for the temperature changes. However, for long-term transportation in the trunk of the car, it is better to blow the boat completely or leave minimal pressure.
What if one tank is pumped faster than the others?
This could indicate a clogging valve or, in the worst case, a leaky bulkhead. Check the valve for dirt. If the adjacent compartment is also inflated during pumping, the internal bulkhead is damaged and the boat needs repair in the workshop.
Can I assemble a boat at a negative temperature?
Modern materials allow boats to operate at temperatures as low as -30°C, but in the cold, PVC becomes stiff and less elastic, it is better to assemble in a warm room, and in the cold only to pump the boat, sharp movements and bending of the frozen material can lead to microcracks.
