Transporting an inflatable vessel in a deflated form is convenient, but for those who appreciate time on the water, it is much more practical to transport it in a assembled state. PVC bootIt's a solution that turns the roof of the car into a reliable platform to move the boat to the descent point, and it avoids long builds on the shore and immediately starts fishing or cruising.
But the choice of a mounting system is not an easy task, and the market offers many options, from universal frames to specialized paddings, and it is important not to get confused in terms. The wrong design can damage the sides or cause accidents at high speed.
In this article, we will explore all the nuances of selecting, installing and operating inflatable boat transportation systems to ensure that your path to the water is safe and comfortable.
Types of constructions for the carriage of inflatable vessels
The first thing the boat owner encounters when looking for a solution is a variety of form factors. The main division is by the type of support surface: it can be rigid trough frames or soft pads. Rigid frames are welded structures from the profile that completely repeat the contours of the bottom, ensuring maximum rigidity of the fixation. Lodges They are made up of separate supports covered with soft material, which allows you to repeat the shape of the boat more flexibly.
The choice between these two types often depends on how often you plan to remove the system from the car. If the trunk is standing constantly, a rigid frame may be more convenient, since it is less susceptible to deformation from the wind. However, for seasonal use, when the structure needs to be put and removed in the garage, modular systems with pads benefit from less weight and dimensions in disassembled form.
⚠️ Warning: Using open metal frames without protective coating (powder paint or galvanizing) will quickly lead to corrosion. rusty pipes can leave undetectable marks on the sides of your boat.
Also worth mentioning are the combined variants, which use adjustable brackets, which allow you to change the angle of inclination and width of the supports, adjusting to different models of floating vehicles. Universality This is a key factor if you have not one boat in your garage, but two or three boats of different sizes.
Selection criteria: load capacity and materials
At first glance, it may seem that the PVC boat weighs a little, but in the running condition with the engine, gas tank and anchors, the weight can reach 100-150 kg or more. loading capacity The first thing you need to look at is the luggage system, and cheap Chinese analogues often sin with thin-walled aluminum, which can fold under load when braking sharply.
The materials of manufacture also dictate the life of the product. The optimal option is considered aviation aluminum with anodized coating or stainless steel. Plastic elements are allowed only in the places of attachment of the pads, but the supporting frame should be metal. It is important to check the quality of the welds: they should be smooth, without pores and inflows.
- 🚗 Compatible with the car: Make sure the model you choose fits the type of roof of your car (having rails, gutters or a smooth roof).
- 🌊 Water protection: the design should not accumulate moisture inside the profiles, otherwise in winter this will lead to a rupture of the metal.
- 🔒 Possibility of locking: The presence of regular holes for cables or locks will protect the boat from theft in the parking lots.
And aerodynamics, too, because bulky designs create sailing, which increases fuel consumption and cabin noise, and modern models are often streamlined, which reduces air resistance. The optimal height of the trunk side is 10-15 cm That's enough to hold the boat, but not too much to create vortices of air.
Comparative specifications of popular models
To make the choice easier, we have compared three typical market participants, and the data in the table will help you to assess the value for money and the functionality of different solutions.
| Parameter | Budget frame (Steel) | Aluminum profile (Middle class) | Premium bed (Regulated) |
|---|---|---|---|
| Structure weight | 18-22 kg | 8-10 kg | 6-8 kg |
| Max, load. | 80 kg | 120 kg | 100 kg |
| Corrosion protection | Powder paint | Anodizing | Stainless steel + plastic |
| Universality | Under a specific model | Regulated framework | Complete adaptation |
As you can see from the table, steel structures are heavier but cheaper, but their weight can significantly reduce the payload on the roof of a car, especially if you have a small car. Aluminum counterparts are lighter and more durable, but they cost more.
When choosing, also pay attention to the system of attachment to the car. Some models require drilling of the roof, which is categorically not recommended for modern cars. It is better to choose systems on clamps or magnetic mounts (for cars with a metal roof), which do not violate the integrity of the body.
Step-by-step instructions for installation on the roof
Truck installation is a process that requires careful and technological attention, and an error in the installation phase can result in loss of cargo on the track. Be sure to read the manufacturer's instructions before starting work, as the geometry of the mounts may differ.
Start by preparing the surface. The roof should be clean and dry. If you use a system with suction cups or clamps, degrease the contact areas. Set the crossbars (if there are none) strictly perpendicular to the axis of the car, keeping the recommended distance between them (usually 60-70 cm).
☑️ Pre-installing check
Then you place the frame or the padlock on the crossbars. Don't tighten the fasteners to the end at once. First, make all the bolts, align the structure in the center of the roof, and then make the final puff. Use the dynamometer key, if possible, so as not to break the thread or deform the profile.
⚠️ Warning: When installed on a car with a panoramic roof, make sure that the boot supports do not fall on the glass surface.
After installation, be sure to check the reliability of the fixation. Try to loosen the structure with your hands - it should sit dead. If there is a backlash, tighten the mounts or use additional rubber pads to eliminate gaps.
The first 20-30 km after installation, move at a speed of no more than 60 km / h, periodically stopping and checking the tightening of the fasteners - the metal has the property of shrinking under load.
Rules for safe transportation and fastening of the boat
Even the strongest trunk will not hold the boat if it is not properly secured. The main enemy on the track is vibration and wind load, which can shake even tightly tightened knots. For fixation, use only specialized ratchet straps, not conventional ropes.
The boat must be stowed downwards, strictly in the center. Inverted boat (sides down) has a greater sailing capacity and risk of being blown by the wind above. Belts are passed through special eyelets on the frame or cover the sides, but should not squeeze the cylinders to the state of "stone".
- 🔗 Insurance: Always use an additional safety cable tied to the car's towing pads in case the main belts are loosened.
- 🌬️ Sailing accounting: When side winds, slow down speed, as the boat on the roof works like a sail and can overturn the car.
- 🛑 Controls on the way: Stop every 50-70 km to check the tension of the belts, as they tend to stretch.
Pay special attention to protection against theft. Leave the boat on the roof in the night parking lot unattended is a risk. Use cable locks, passing the cable through the cylinders and the trunk frame, locking it on the lock. Remove the removable parts of the trunk, if the design allows.
The main principle of safety: triple fixation (main belts + safety cable + locks) ensures the safety of the cargo even in extreme conditions.
System care and preparation for winter storage
Aggressive environments, salt, dirt and temperature changes quickly disable metal structures. After each trip, especially along the sea coast or in the rain, it is recommended to rinse the trunk with fresh water, which will wash away salt and reagents, which are the main catalysts for corrosion.
Before long-term storage (for example, for the winter), the structure must be dismantled, thoroughly washed with detergent and completely dried. Places of contact of metal with metal (bolt joints) are better treated with conservation lubricant or lithium spray.
Keep the trunk in a horizontal position in a dry room. If this is not possible, hang it or put it vertically to prevent deformation of the profile under your own weight. Regularly check the condition of rubber seals - if they crack, they need to be replaced, otherwise they will scratch the roof of the car.
How to remove scratches from an aluminum profile?
Small scratches on anodized aluminum can be polished with a special paste for metal (for example, Autosol). Deep damage where gray metal is visible must be painted to prevent oxidation, otherwise the stain will grow.
Compliance with these simple rules will extend the life of your equipment for many years. A quality trunk is an investment in comfort that pays off with the time and effort saved on each trip to the pond.
Frequently Asked Questions (FAQ)
Can I carry a boat with an engine installed on the trunk?
It's not recommended. It puts extra stress on the engine, shifts the center of gravity, and increases the sailing speed significantly, and it can damage the lower unit of the motor or the transom mounting, and it's better to drive in the cabin or in a separate trailer.
What is the maximum speed with a boat on the roof?
Truck and traffic manufacturers typically limit the speed of oversized rooftop loads to 90 km/h on the highway, which dramatically increases the risk of a boat being blown off by the wind and losing control of the car due to a shift in the center of mass.
Do I need to register the trunk with the boat in the traffic police?
However, if the width of the boat with the trunk exceeds the width of the car by more than 40 cm on each side (or 20 cm under the new rules if the cargo is out of dimensions), the installation of a sign "Big cargo" and, in some cases, permission to carry is required.
Will a plastic trunk hold a heavy boat?
Modern composite materials are highly durable, but for heavy boats (hard bottom or full assembly with equipment), a metal frame is preferable. Plastic can become brittle in the cold and crack from impact or overvoltage.
