An inflatable floater is not just a piece of cloth with cylinders, but a complex engineering design that requires a competent approach to preparing for a launch. How professionally the initial pumping is performed affects not only the speed of assembly, but also the durability of the material, as well as the safety of the crew while sailing. Many beginners make the fatal mistake of relying solely on tactile sensations, which often leads to pumping in the heat or not pumping into the cold.
It is important to understand that air-borne The inside of the cylinders varies with the temperature of the environment, and cold water can significantly reduce internal pressure, while the scorching sun can turn a hard side into a dangerous time bomb, which is why knowing the right sequence of actions and technical nuances is a must-have skill for any hydraulic motor.
In this article, we'll look at all the stages of preparing the boat, from the selection of the site to the final seam check, so that your launch goes without technical problems. We'll discuss why you can't use car compressors without control and how to avoid deformation of the bottom. Proper operation is the key to the fact that the car is not used without control. PVC material It will last for many years, maintaining its strength specifications.
Selection of location and surface preparation
Before laying the boat, you need to carefully inspect the intended site for assembly. The ideal option is a flat area, cleared of fine debris, branches, sharp stones and spiny vegetation. Even a small knot or a sharp pebble under the pressure of a person's weight can damage the bottom of the cylinders or bottom.
If you're on a sandy beach, make sure the sand doesn't contain broken glass or metal shards. In the forest area, it's best to put a special protective mat, awning, or at least a plastic film under the boat, which will protect the fabric from punctures and abrasion on the rough surface of the ground.
⚠️ Warning: Never leave a decomposed but not yet inflated boat in direct sunlight for a long time. Polyvinyl chloride, which is made of cylinders, can overheat, which will lead to deformation of the seams before the start of operation.
Place the craft with valves upwards so that it doesn't get dust or sand. If the wind is strong, lock the corners of the boat or have the assistant hold the edges until you start to supply air, which will prevent the structure from shifting and abrasive particles from entering the valve system.
Connecting the pump and starting the pumping
To start the process of inflation, you need to choose the right pump nozzle. Most modern boats are equipped with valves such as valves. High Pressure Or petal variants that require a specific nozzle diameter: an improperly selected cone may damage the rubber valve seal or simply not ensure the tightness of the connection.
In the initial phase, when the cylinders are still soft and unshaped, you can supply air quickly using a large volume but low pressure. foot-pump Or high-performance electric pumps, the main task is to straighten the folds of fabric and give the cylinders a primary volume.
Watch the valve position while you're working. If you're using a mechanical pump, try to make rhythmic movements without pulling the hose abruptly so you don't knock the nozzle out of the socket. In the first minutes, the boat should just "swipe out" and become elastic, but still very soft to the touch.
Use an electric pump only 70-80% of the pump, then switch to a mechanical one, which will save the pump engine from overheating and allow you to more accurately control the final pressure.
Pumping sequence of compartments
There's a very strict algorithm that's not recommended for boat manufacturers to break, and they usually pump the bow and the aft, then the board, and then the last thing. bottom This sequence allows the load to be evenly distributed across the seams.
If you start at the bottom, when you pump the sides, the pressure on the central seam will increase critically, which can lead to its rupture or deformation. The sides will swell, press on the already inflated floor, creating unnecessary tension. So always leave the floor (or keel) for the final stage.
- 🚣 Phase one: Forward and aft cylinder (up to about 50-60% of the volume).
- 🚣 Stage two: On-board cylinders to a state of light elasticity.
- 🚣 Phase three: Bringing the sides to working pressure.
- 🚣 Phase four: Pumping the inflatable floor (keel) to the maximum value.
It's important not to pump one side harder than the other. If the left side is hard and the right side is soft, the boat on the water will start to heel, which will worsen the driving performance and can lead to a loss of performance. differentiation Try to do the same number of swings on each side when using the mechanics.
Pressure control and operation of the pressure gauge
The most critical aspect is the achievement of working pressure, which for most boats is between 0.25 and 0.35 atmosphere (bar), and many users mistakenly assume that the harder the side, the better. pressure-out In hot weather, the seams can break as the air inside the balloon expands when heated.
Using a pressure gauge is a must if you want to be sure of safety. Visually and by touch, determining the exact pressure of 0.25 bar is extremely difficult, especially if you have no experience. The pressure gauge is often built into the housing of quality electric pumps or comes complete with foot models.
| Air temperature | Recommended pressure | Action |
|---|---|---|
| Cold (+5...+15°C) | 0.25 - 0.28 bar | Pump to the point, the risk of rupture is minimal |
| Heat (+15...+25°C) | 0.25 - 0.30 bar | Comply with standard values |
| Hot (+25...+35°C) | 0.20 - 0.25 bar | Do not push to the maximum, blow the air |
⚠️ Warning: If you pump the boat in a cool garage or in the morning and then take it out in the sun, the pressure inside the cylinders will surely rise. Always leave a small supply or blow some air before going out on a hot day.
What if the gauge is too high?
If you have pumped the boat, do not try to squeeze air through the valve by clamping it with your finger - you can damage the mechanism. Use the back side of the pump (if there is a blow function) or gently press the valve stem with your nail or a thin object, controlling the air output by sound.
Final check and elimination of distortions
Once all the compartments are inflated, you need to do a visual inspection and tactile check, run your hand over the surface of the cylinders: they should be uniformly elastic throughout the area, there should be no obvious "bubbles" or vice versa, dents.
Pay special attention to the transom board (if any) and the thong attachment areas. In these areas, the fabric experiences maximum load. If the boat has an inflatable keel, check its tension - it must be hard as a stone, ensuring the correct hydrodynamics hull.
☑️ Final check of the boat
Check the valves for leakage. Sometimes after active pumping, the valve may "poison" if a grain of sand has hit it or if it is not fully closed. Press the cylinder next to the valve and listen: a distinctive whistle will indicate a problem that needs to be fixed before launching.
Features of operation in different conditions
Environmental conditions dictate their rules. In open water, where there is excitement, the sides of the boat experience shock loads. In such cases, it is useful to keep the pressure closer to the upper limit of permissible, so that the cylinders better extinguish the impacts on the water.
When fishing in reed-covered areas or in shallow water with snags, on the contrary, it makes sense to slightly under-pump the boards (0.05 bar less than normal), this will make them softer and less susceptible to punctures on the sharp edges of plants, and also improve cushioning when touching the bottom.
Winter fishing requires a special approach. In the cold, PVC becomes tough and less elastic. You only need to pump an ice boat in a warm room or garage, and in the cold, the pressure will inevitably drop. You need to pump it on the ice very carefully, using only a hand pump, so that you do not overcool the material and create condensation inside the valves.
The golden rule of water motors is that it's better to lose 10 percent of the boat than to pump it over. It's fixed in 30 seconds on the water, and pumping in the heat can cause the seams to rupture permanently.
Frequently Asked Questions (FAQ)
Can I swing a boat with a car compressor?
You can use a car compressor, but with great care. They often don't have a precise pressure gauge and can develop too high a pressure that's dangerous for PVC. They also quickly put the car's battery down, and it's better to use them only for the initial straightening of the cylinders, and do the finishing work with mechanics.
Why did the boat become soft after launching?
The reason is probably the temperature difference: water in a body of water is usually colder than air, especially in spring or autumn, when it comes into contact with cold water, the air inside the cylinders compresses (physical law), and the pressure drops. This is normal: after 10-15 minutes on the water, the boat needs to be pumped to working condition.
How to keep the boat: in a deflated or pumped?
For long-term storage, the boat must be blown, washed and dried. Storing in a pumped state (even partially) leads to constant stress in the seams and can cause fatigue of the material, especially if the room temperature changes.
What to do if the valve poisons the air?
Try to tighten the valve cover first. If it doesn't work, unscrew the valve (usually with a special key from the kit), wash it from sand and dirt, check the integrity of the rubber gasket. Often the problem is solved by simple cleaning.
