The end of the navigation season or just preparing for the weekend always poses the same challenge for the owner of the boat: how to compactly and safely remove the property. Incorrect stowage can cost you dearly, because the PVC material is sensitive to permanent crunch and aggressive environment. Many beginners make the mistake of trying to shove a wet or dirty vessel into a bag, which inevitably leads to mold and loss of sealed seams.
The dismantling process requires patience and a certain algorithm of actions. If you want your boat to last for many years, you need to strictly control the humidity and cleanliness of the surface before packaging. In this article, we will discuss all the stages of preparation, drying and folding to eliminate common errors.
Ignoring storage often leads to unpleasant surprises in the form of microcracks or a rotting smell next season, a properly folded boat takes up minimal space in the trunk of a car or garage, and let's figure out how to turn a bulky structure into a neat bundle ready for long-term storage.
Primary preparation and surface cleaning
The first and most important step is to thoroughly clean all surfaces of dirt, sand, silt and algae, and the abrasive particles left at the bottom of the cylinders act like sandpaper when folded, damaging the protective layer. PVCFor washing, it is best to use a soft sponge and warm water with the addition of ordinary household soap or specialized means for inflatable structures.
Special attention should be paid to hard-to-reach places: the corners of the transom, the joints of cylinders and the area around the valves. This is where moisture and organic matter most often accumulate. If you used a boat in salt water, fresh water rinsing becomes a mandatory procedure, since salt crystals can crystallize and corrode the material during prolonged storage.
After washing, you need to do a visual inspection for foreign objects. In the folds of the material, small stones or branches often hide, which, when pressure is rolled up, can pierce the side. Use soft fabric to wipe the surface dry before starting the main drying process.
⚠️ Note: It is strictly forbidden to use gasoline, acetone, chlorine-containing solvents or aggressive household chemicals for cleaning, which destroy the polymer structure of the material, making it brittle and vulnerable to puncture.
Technology of high-quality drying
The most common mistake is to fold a wet vessel, and the moisture left inside the rolled-up cylinders creates ideal conditions for bacteria and fungi to multiply, which not only cause unpleasant odors, but also destroy glue in the seams. Drying should take place in the shade, because direct sunlight combined with heat can lead to uneven air expansion and deformation of glue compounds.
You can use airflow to speed up the process. Some owners plug in a compressor or an electric pump in blow mode (if the design permits) or simply leave the valves open in a draft. It's important to make sure that not only the outer surface, but also the inner surface of the cylinders, where water could get into during operation, has dried up.
Drying time is directly dependent on humidity and ambient temperature. On a hot summer day, a couple of hours is enough, whereas in cool autumn weather the process can take days. Don't rush to pack the product until you make sure that all surfaces, including the bottom and cockpit, are completely dry.
Dismantling of attachments
Before deflating cylinders, all removable elements must be removed, including seats (banks), inflatable floor (if separate), stringers, paddles, anchor ducks and protective linings. Each element must be cleaned and dried separately. Metal parts such as motor mounts or can fittings require special drying to avoid corrosion.
If your model is equipped with a hard floorboard floor of aluminum or moisture-resistant plywood, it also needs to be wiped dry with rags. Aluminum profiles (stringers) should be wiped with silicone grease so that they easily enter the slots the next time and are not subjected to oxidation. Wooden elements (plywood bottom) can not be stored in a sealed state wet, otherwise they will swell and lose geometry.
All small parts, bolts and nuts are recommended to be folded in a separate bag or container so that they do not get lost during transportation. Losing even one bolt of the can mount can be a problem during the next outing. Carefully place all components next to the boat for inspection.
Lubricate metal stringers and bolts with silicone lubricant or lithole before storage – this will prevent the metal from boiling and make it easier to assemble next season.
Blow-out procedure
The process of air removal must be controlled and consistent. Abrupt opening of valves on a fully pumped boat can cause the water residues inside to splash out sharply or spread out to internal partitions, making further drying difficult. It is recommended to first lower the cylinders slightly, flip the boat to pour water, and only then open the valves completely.
There are two main types of valves: petal valves and screw valves (such as Bravo). For screw valves, you need to twist the center part counterclockwise to the point, then press the center to exit air. Petal valves simply open outwards. It is important not to use excessive force, so as not to break the thread or damage the mechanism.
The order of deflation also matters, usually starting with the bow cylinder, then moving to the side cylinders and ending with the stern one, which allows you to keep the structure stable during operation, and if the boat has an inflatable floor (NDB), it is blown out last after the sides have already lost rigidity.
You don't need to use powerful compressors to pump air, because they can pull the residue of water from the pores of the material into the cylinder, creating a moist environment there, and the best way is to naturally extrude air under your own body weight or twist it neatly.
Algorithm of folding and packaging
When all cylinders are deflated, the most important step is to form a compact bundle, and the main goal is to avoid sharp clamps in the same places for each package, and the constant bending of the material along the same line leads to microcracks and eventual depressurization, so it is recommended to change the bending line every time.
First, you fold the boat down the center axis, and if you have a model with paioles, they should be removed by that point, and the sides are carefully superimposed on each other, and then you start the process of twisting or folding with an accordion, and twisting from the valves to the transom is considered a more gentle method, because it allows you to squeeze out as much residual air as possible and avoid sharp overbending.
When folding with an accordion, you need to make sure that the layers lie flat, without distortion. Once the rectangular shape is formed, the bundle is placed in the packaging bag. You shouldn't push the boat by force; if it doesn't come in, it means that there is too much air left in it or it is folded carelessly.
☑️ Checklist before packaging
It is important to place the valves inside the folded structure correctly, and they should not rest against solid objects or bend at a sharp angle, as this can damage their mechanism or interfere with the leakage, and it is best if the valves are located in pockets formed by folds of material.
Features of storage in the off-season
Storage conditions are no less important than proper packaging: the optimal temperature for storing PVC products is from +5 to +25 degrees Celsius; the sharp temperature changes typical of unheated garages or country houses in winter can adversely affect the elasticity of the material. PVC becomes brittle in severe frost, and any careless movement can lead to cracks.
Indoor humidity should be moderate. Raw basements are the enemy of inflatable boats, even if they are well dried before packaging. Condensation formed by temperature changes inside the bag can trigger the process of molding. The ideal place is a dry storage room in the apartment or a heated garage.
The boat can be stored in either a deflated or partially pumped state (if space permits). However, for most owners, the best option is to store it in a deflated form in a protective bag. Every few months, it is recommended to open the bag, straighten the boat and check its condition, giving the material a breath.
| Parameter | Optimal value | Critical significance | Consequences of violation |
|---|---|---|---|
| Temperature. | +5...+25 °C | Below -15 °C/Above +40 °C | Loss of elasticity, deformation |
| Humidity | 40-60% | Above 80%. | Mold appearance, stitch rotting |
| Light | Absence of direct rays | Direct sun (UV) | Color burnout, PVC breakdown |
| Neighborhood | Clean dry place | Fuels, oils | Chemical destruction of material |
⚠️ Warning: Do not keep the boat near heating appliances or open flames. High temperatures can cause material to melt or spontaneously ignite, as PVC is a combustible material.
Typical errors in packaging
One of the most common mistakes is to use the wrong covers: a plastic film wrapped tightly around the boat creates a greenhouse effect, preventing the material from breathing. This is guaranteed to lead to condensation and mold. The bag must be made of breathable fabric, such as dense polyester or special autotextiles.
Another mistake is to store the boat with a chainsaw, fuel canisters or fishing chemicals, and the vapors of gasoline and corrosives penetrate the PVC structure, softening it and reducing its strength. PVC material has the property of absorbing vapors of petroleum products, which makes it loose and sticky, it is almost impossible to restore such damage.
Also often ignored is the condition of the storage bag itself: a dirty, wet or torn bag will nullify all efforts to prepare the boat. Before you put the rolled-up boat in there, shake out the garbage, sand and make sure that it is intact.
What to do if the boat is frozen?
If you have to transport a boat in extreme cold, don't try to spread it out or pump it right away. Put it in a warm room and leave it for at least 12 to 24 hours. The material must warm up evenly throughout the thickness to regain its elasticity. Trying to bend the frozen side will result in a guaranteed rift or crack.
Proper care of an inflatable boat is the key to your safety on the water and saving your family budget. Regular maintenance and proper storage allow you to operate the product for 10 years or more without losing your driving performance. Remember that the time spent on quality preparation for storage will pay off with the long life of your boat.
The main secret of a long life of a PVC boat is absolute dryness before packaging and the absence of sharp creases in the same places at each folding.
Frequently Asked Questions (FAQ)
Can I keep a boat on the balcony in winter?
Storage on an unglazed balcony is highly undesirable, the material will be exposed to ultraviolet light, temperature changes, snow and rain, which will quickly lead to its destruction, if the balcony is glazed, you need to provide protection from direct sunlight and make sure that the temperature does not fall below critical values, and the humidity is not excessive.
Do I need to lubricate the boat before storage?
It is not necessary to lubricate the entire surface of the boat. It is enough to clean a dry surface. However, it is recommended to treat metal parts (stringers, can mounts, valves) with silicone grease to prevent corrosion and facilitate assembly next season.
How often should I move the boat for long-term storage?
It is recommended to take the boat out of the bag every 2-3 months, slightly straighten it and let it “ventilate”, this will help to avoid sticking layers of material and forming persistent folds, and also will allow you to control the absence of mold or rodents.
What is the danger of sand left on the boat when packing?
Sand consists of quartz, the hardness of which is higher than that of PVC. When stored in a folded state under the pressure of its own layers and the weight of the structure, the grains of sand work like an abrasive, crashing into the material and creating microscopic damage that can eventually develop into punctures.
