Transportation of inflatable watercraft is a process that requires special attention to detail, because the reliability of fixation depends not only on the safety of traffic, but also on the safety of expensive property. PVC boats They are more susceptible to mechanical damage, friction on hard surfaces, and uneven load distribution. Incorrect stacking or weak tension of the fasteners can lead to punctures, seams rupture, or even the loss of a boat at high speed.
Experienced boaters know that each model has its own design features, so there is no universal recipe, but the basic principles remain unchanged. graffiti-trailerIgnoring these nuances turns the trip into a lottery, where the stake is the integrity of your equipment.
In this article, we will discuss all the steps of the process, from checking the condition of the pawns to the final fixation with the belts, you will learn how to protect the sides from rubbing, why you can not use chains and how to correctly distribute the weight to avoid shifting the center of gravity during maneuvers.
Preparation of trailer and check of anchorages
Before putting the boat on the platform, you need to conduct a thorough audit of the vehicle itself, special attention is paid to the condition of the pads, the supports on which the body directly lies, if they are left with traces of old dirt, sharp edges of metal or rust, the risk of damage. PVC tubes It is recommended to use special plastic linings or carpeting, which soften the contact.
Check the working of all the moving elements: winches, stoppers, rollers and brackets. The mechanism of the winch should work smoothly, without jamming, and the cable or belt should not have scuffs. Fixers They must hold the position securely, without allowing spontaneous weakening under vibration, and any failure here can cause an emergency on the road.
⚠️ Note: It is strictly forbidden to use metal chains or cables for fastening inflatable boats without additional soft winding. Metal under load is absorbed into PVC, causing irreversible destruction of the material structure.
Make sure the surface of the trailer is clean and dry. Sand or small stones caught between the sides and the beds act as abrasive when friction. Just wipe the supports with wet rags before loading to eliminate this risk factor.
Proper positioning of the boat on the platform
The installation of the boat begins with its precise positioning, the vessel must be located strictly on the central axis of the trailer, which ensures uniform weight distribution and stability during movement, even a few centimeters can lead to uneven tension of the belts and increased load on one of the sides.
It is important to set the boat along the length correctly, the nose should be snugly adjacent to the nose support or be fixed with a winch so that the keel lies on the supports with its entire length. kielson (longitudinal beam on the bottom) will not rest on the pawns, under load it can bend or break, which will lead to deformation of the entire body.
When stowed, make sure that the transom (stern) does not hang too much, but does not rest against the cross of the trailer with excessive force. The optimal position is when the transom is above the frame or on a special support element, excluding contact with sharp metal angles, This is especially true for boats with a hard transmolant.
For models with high pressure inflatable keel (HPD) or sleigh, it is critical to provide support along the entire length. If the bed is short, additional supports should be used to avoid the hammock effect, when the middle sags and the edges are clamped.
Selection and use of belts for fixation
The quality of the slinging depends on the materials used. PVC boats are ideal for fixing nylon or polyester belts with a ratchet mechanism (rattle) or frictional puffs. They are strong enough, do not stretch excessively when moisturized and, most importantly, have a soft structure that is safe for cylinders.
The width of the belt should be sufficient to distribute pressure - optimally from 25 mm and above. Narrow slings can crash into the sides under load, creating high voltage points. Furniture (hooks, carbines) should be made of corrosion-resistant materials, such as stainless steel or galvanizing with a quality coating.
- 🔹 Belts with a ratchet mechanism allow you to accurately regulate tension and reliably fix the load, excluding spontaneous weakening.
- 🔹 Friction belts (without metal elements in the contact area) are preferable for places where direct contact with inflated cylinders is possible.
- 🔹 The use of extension linings made of foam or dense fabric at the ends of the belts protects PVC from scratches with metal hooks.
When tightening belts, it is important to observe measure: Excessive force can deform cylinders, especially in hot weather when pressure inside the boat increases. Tension. It should be such that the boat sits tightly in place, but does not squeeze to loss of shape.
Safe slinging technique with transom belts
The main method of fixation is the use of transom belts thrown over the boat hull. The minimum number of attachment points is two: one in the bow (closer to the middle) and one in the stern. For boats longer than 3.5 meters, it is recommended to add a third, central belt.
The belting technique requires carefulness, the sling must pass over the cylinders without touching the sharp corners of the trailer frame. cover-case Or a tight rubber lining, which will prevent the fabric from being rubbed when it's vibrating.
Tighten your belts one by one, gradually increasing the tension. First, slightly tighten the nose belt, then the aft belt, and only then bring the force to working condition, this sequence avoids skewing the boat during the fixation process.
⚠️ Warning: Do not allow the belt to twist when tightened. The twisted belt loses up to 50% of its strength and creates uneven pressure on the narrow strip, which can damage the balloon.
The free ends of the belts must be carefully assembled and fixed with a rubber band or a special clip. The dangling tails can fall under the wheels of the trailer or wind on the suspension elements, which will lead to rupture of the sling and loss of cargo.
Protection of PVC from friction and damage during transportation
The main enemy of an inflatable boat on the way is vibration and friction. Even the microscopic movement of the boat relative to the supports for hundreds of kilometers can wipe the material to holes. protector.
The most effective method is to use special rugs made of foamed polyethylene or felt, which are laid on the bed before installing the boat, and there are special spray-polyrolys that create a slippery film on the surface of PVC, which reduces the friction coefficient.
Pay special attention to the points of contact between the belts and cylinders, you can put small pieces of foam under the belt or use belts with already built-in soft lining, this is especially important for long stretches on high-speed highways.
Lubricate the cylinders of the boat in front of the expensive special silicone PVC lubricant - this will reduce friction and protect the material from drying and ultraviolet light.
If you are transporting a boat with the engine installed (which is not recommended but is sometimes practiced), make sure that the lower unit is securely fixed and does not dangle. Vibration from the motor is transmitted to the transom and can damage the place of attachment of the transom to the cylinders.
Pressure control and temperature expansion
One of the most important safety aspects is the temperature expansion of the air. When heated in the sun, the pressure inside the cylinders increases, and if the boat is pumped "before ringing" on a cool morning, the pressure can exceed critical values by lunch in the sun, leading to rupture of the seams or deformation.
It is recommended to leave a small margin of pressure before loading on the trailer. The optimal working pressure for transportation should be 10-15% below the maximum specified in the product passport. This will allow the cylinders to be depreciated without the risk of rupture.
On the way, at long stops, be sure to check the tension of the belts. Heating can cause materials to expand and the belts may weaken. Conversely, if the boat overheats and swells, it may be necessary to blow some air to avoid damage.
| Parameter | Cold weather (<10°C) | Hot weather (> 25°C) | Normal conditions |
|---|---|---|---|
| Pressure in cylinders | Standard (0.2 atm) | Reduced (by 10-15%) | Worker (0.2-0.25 atm) |
| Belt tension | Reinforced (material tanning) | Control (bloating risk) | Standard. |
| Risk of damage | Cracks on the folds | Seed rupture, deformation | Minimum |
What to do if it rains on the way?
If a rainstorm starts, try to slow down. Wet PVC becomes more slippery, and the risk of displacement of the boat under the belts increases. After stopping, be sure to tighten your belts, as wet nylon can stretch out a little, and the water will add weight.
Typical errors in the fastening of inflatable boats
Even experienced users sometimes make mistakes that can cost boats, the most common being saving on the number of belts. Trying to strap a three-meter boat with one belt in the middle is a guaranteed way to get a dangling load that can slip off at any moment.
The second mistake is the use of poor-quality containers or ropes, which tend to stretch and require constant monitoring of knots that can be unleashed by vibration. Snoring mechanisms In this regard, it is much more reliable and safer.
- 🔹 Ignoring checking the condition of the lodgings before each trip.
- 🔹 Excessive zeal when tightening belts, leading to flattening of cylinders.
- 🔹 Lack of fixation of free ends of belts, which leads to their getting into moving parts.
It is also a mistake to transport a boat with a rigid floorboard installed (floor), if it is not fixed inside. When shaking, sheets of plywood or aluminum can begin to “walk” inside the boat, rubbing the bottom from the inside or damaging the valves.
☑️ Checklist before leaving for the track
Specifics of fastening of boats with hard bottom and BDND
Hard-bottomed boats (plywood, aluminum) require a special approach to the distribution of supports. The pressure should be on rigid structural elements, not on soft cylinders. If the trailer bed does not correspond to the shape of the bottom, load points may occur.
High-pressure inflatable floor (HPD) models are more flexible and require uniform support throughout the area, critically important for them to keep the keel on the support, and the lack of keel support will cause the boat to bend under the weight of the motor and passengers (if the boat is heavy) or simply when the belts are stretched, with a banana.
These boats often use additional side support or trailer wings to keep the cylinders from falling on their side when the trailer rolls on corners, especially for narrow models.
⚠️ Warning: When transporting NDND boats in hot weather, monitor the pressure in the keelson, its rupture or deformation will lead to a complete loss of driving qualities of the boat on the water.
Use wide belts for these models to cover more volume and distribute pressure. A narrow belt will simply cut the inflated quill cylinder when shaking hard.
The main principle of safe transportation is that the boat should become one with the trailer, not being able to move to either side, but should not be squeezed to deformation.
Additional safety measures on the way
Even a perfectly fastened boat requires attention on the road. Traffic rules require the driver to monitor the cargo. Stop 10-15 km after starting and check all the mounting points. Vibation of the first kilometers often reveals understretched elements.
When you're on dirt roads, slow down. Shaking on the bumps creates dynamic loads that are many times more static than the boat's weight, and at that point, the belts experience peak stresses.
If you plan to stay for a long time, especially in a crowded place, consider using additional cable locks or removing attachments. The trailer boat is a tasty piece for fans of the light trophy.
Can I transport a PVC boat in a deflated state on the same trailer?
Yes, you can, but you need to remove all the sharp elements from the pads, as the blown PVC is much thinner and more vulnerable. It is advisable to cover the platform with a soft material (carpet, blanket) to avoid contact with dust and small stones that can damage the fabric when friction.
How often do I need to change the belts to fasten the boat?
The life of the belts depends on the conditions of use. If they are constantly under the sun (UV radiation destroys synthetics) and in water, they should be changed every 2-3 seasons.
What to do if the belt bursts on the way?
Always have one extra belt or universal mount kit in hand. If the belt bursts, you must stop immediately in a safe place. Use Scotch or rope as a temporary measure only to get to the nearest gas station or store, reducing the speed to a minimum.
Do I need to remove the motor during transportation?
Light boats and motors up to 5 hp often practice transportation together, but this puts additional strain on the transom. For heavy motors and long trips along the highway, it is better to remove the motor to eliminate vibration damage to the transmolator plate and reduce the sailing structure.
