For many aquatic motorists, the question of transporting a boat to the descent is one of the most pressing. Often motorists looking for a solution to transport a PVC boat or a small boat wonder: what is the name of the trunk on the roof of a car intended for a boat? In professional environments and car catalogues, the term for this is used for this purpose. boot-staff or, more specifically, boat-carBut there are many synonyms that can confuse a beginner.
The correct selection of equipment directly affects the safety of movement and the safety of your property. Transportation of the boat The rooftop is a complex engineering process that requires consideration of aerodynamics, weight and cargo dimensions. Incorrectly designed design can cause a vehicle to shift its center of gravity, increase fuel consumption, or worse, lose track load, so it's important to understand the difference between universal boxes and specialized systems for water technology.
In this article, we will discuss in detail what types of fasteners exist, what they are called in manufacturers' catalogs and what to look for when buying. You will learn about the technical nuances of installation and the legal aspects of transporting oversized cargo. Understanding the terminology will help you find the right equipment faster and avoid errors when ordering.
Terminology and basic concepts
First of all, you have to understand the nomenclature, and if you ask the store just "boat trunk," the vendor has a few options. experimental or specialized PVC bootUnlike standard arcs, such systems have an elongated base, often exceeding the dimensions of the car, which is necessary to accommodate long-range cargo.
There is often confusion between the terms "baggage" and "farcope." Although the farcope is also used to transport boats, in this context we are considering the use of the "baggage" in the transport of boats. roofingThey are divided into open systems (plugs or baskets) and closed systems (specialized kofras). Inflatable boats are most often used open systems with a soft coating, so as not to damage the cylinders.
The key element is the load-bearing capacity. trunker It is important to distinguish between static and dynamic load: if the roof can withstand 100 kg, then the maximum permissible weight in motion is usually 50-75 kg. Exceeding these norms leads to deformation of the roof and nguy consequences.
⚠️ Attention: Never use standard universal arcs to carry heavy aluminum boats without first calculating the total weight. Overloading the roof of the car can cause the mounts to break off at high speed.
Design features of boat trunks
Specialized systems for the transport of boats are significantly different from standard solutions for suitcases or bicycles, the main emphasis is on the length of the bearing profiles. lengthened-baseThis is a type of vent that often extends beyond the projection of the roof of the car in the front and rear, and requires the use of special adapters to attach to gutters or doorways.
Materials also play an important role: anodized aluminum profiles are the standard of quality, as they do not rust and are of low weight. Steel structures, although cheaper, are susceptible to corrosion, which is especially critical for water-motor applications where contact with moisture is inevitable. Lodges (supports) shall be covered with soft, puncture material or rubber to prevent friction and puncture of cylinders.
Another important thing is the fixation system, and simple straps aren't enough to hold you securely. boat-cargo They have integrated crank belts or special clips, and some models have a rapid disassembly system, which allows you to remove the bulky structure when it is not needed, reducing noise and fuel consumption during normal driving.
- 🚤 Extended base: ensures a uniform distribution of the weight of the boat and prevents the bow or aft from hanging.
- 🛡️ Protective coating: special mats or a fuzzy ribbon on the beds protects the sides of the boat from abrasion.
- ⚙️ Reinforced anchorages: additional support points and more powerful clamps withstand increased wind loads.
Types of fasteners for different types of boats
The choice of the particular type of trunk depends on the material and design of your boat. For PVC inflatable boats, soft beds are the most popular systems, they are curved arcs that repeat the shape of the bottom, covered with a protective material, which allows you to stow the boat in an assembled form (on a transax wheel) or in a case, minimizing the risk of damage.
For rigid enclosures, such as plastic kayaks or small aluminum motors, can be used. V-shaped bracketsThey lock the boat overboard, lifting the bottom above the trunk surface, which provides better ventilation and water drainage, which is important for metal boats that are prone to moisture accumulation, but this requires more complex adjustment and careful alignment.
And the combined systems, which allow you to transport not only the boat, but also the extra equipment: anchors, oars, tents. Universality These solutions are highly valued by avid tourists, but it should be remembered that adding extra elements increases sailing and noise, so for long stretches it is better to use a specialized profile.
Can I drive a motor on the roof with a boat?
Carrying an outboard motor mounted on the boat's trawler is strongly discouraged because of the enormous load on the mounting point and the risk of tearing off. It is better to transport the motor separately in the trunk of the car or in the trailer. If the boat is rigid (for example, aluminum), the motor can be removed and stowed inside, fixing it, but this will require removing the entire structure from the roof for loading.
Comparison of specifications of different systems
It is important to use specific technical parameters when choosing equipment, and here is a table comparing the main types of rooftop boat systems to help you navigate the variety of offers in the market.
| Type of system | Max. boat length (m) | Load capacity (kg) | Difficulty of installation |
|---|---|---|---|
| Universal trunk | 3.0 | 50 | Low. |
| Specialized (PVC) | 4.5 | 80 | Medium |
| Reinforced (Aluminum) | 5.0 | 100 | High. |
| Modular system | 6.0 | 120 | High. |
As you can see from the table, loading capacity Heavy boats require a more massive structure, which in turn affects the aerodynamics of the car, and it's important to consider not only the weight of the boat itself, but also the weight of all the additional accessories you plan to attach to the top.
The complexity of installation is another critical factor: simple systems can be installed in 10-15 minutes, whereas complex modular designs take time and perhaps the help of a second person. For boats longer than 4 meters, it is strongly recommended to involve an assistant to lay the cargo on the roof to avoid injuries and damage.
Use special gear belts, not conventional ropes, which provide uniform tension and do not weaken from vibration on the road.
Rules for safe installation and transportation
Safety is the number one priority in the operation of any additional equipment. Before each trip, you need to conduct a visual inspection of the mounts, special attention should be paid to the points of contact of the trunk with the car body, even a microshift can lead to scratches or, in the worst case, loss of tightness of the mounts.
The process of laying the boat also requires compliance with technology: the boat should be placed strictly in the center of the axis of the car, shifting the load to the side will lead to a change in the behavior of the machine on the road, especially in lateral winds or sharp maneuvers. Centrification It is carried out by adjusting the position of the crossbars on the longitudinal arcs.
The fastening should be carried out at least four points: two front and two rear. The use of only center belts is unacceptable, since during braking inertia can move the boat forward. It is additionally recommended to use safety cables that are attached to the power elements of the body (for example, towing pads), although this is less common for roof transport than for a trailer.
☑️ Pre-departure checks
⚠️ Attention: After the first 10-20 kilometers of the journey, be sure to stop and check the tension of the belts. The new material has the property of slightly stretching under load, and the fasteners can weaken.
Legal aspects and limitations of traffic rules
Transportation of a boat on the roof of a car is regulated by traffic rules. According to traffic regulations, the cargo must not protrude beyond the dimensions of the vehicle more than 1 meter on the side and more than 2 meters on the rear. If your boat is longer and protrudes beyond the rear bumper by more than 1 meter, but less than 2 meters, you need to mark it. sign "large-sized cargo" (Square shield with red and white stripe).
The height of the vehicle should not exceed 4 meters from the road surface, this restriction is rarely violated when carrying boats in passenger cars, but it is worth remembering when planning the route under low bridges or arches, and the cargo should not close the driver's view, external lights, headlights and license plates.
If the traffic police inspector violates these rules, he has the right to issue a fine, and if a poorly secured boat causes an accident, the driver will be responsible, so knowing the rules is not just a formality, but a necessity for every owner of water transport.
Compliance with the rules of marking oversized cargo and reliable fixation is your insurance against fines and accidents on the road.
Do I need to register the trunk for the boat at the traffic police?
The trunk itself (arcs, crossbars) does not require registration in the car documents if it is a regular or certified car for this model. However, if you make structural changes to the body (for example, welding mounts), this is considered a change in design and requires registration. Conventional removable systems on clamps do not require registration.
Can I carry a boat with pumped cylinders?
Technically, you can, if the load capacity of the roof and the trunk allows, but it creates more sailing. At high speeds, wind loads can become critical. It is recommended to lower cylinders by 10-15% when transported over long distances or in hot weather to avoid breaking from air expansion.
How to protect the roof of the car from scratches?
Use special protective films or mats under the mounting points of the trunk. Also regularly clean the roof and the supports themselves from sand and dirt, which act as an abrasive. When you park in the sun for a long time, it is better to remove the trunk, as the temperature difference under the mounts can adversely affect the paintwork.
