The decision to buy a trailer for a PVC boat is often a turning point for the owner of a small boat. On the one hand, it eliminates the need to assemble an inflatable vessel every time, launch it in an uncomfortable place and waste time on long preparations for fishing. On the other hand, a new facility is emerging that requires maintenance, proper operation and, of course, financial investment during the purchase phase.
The market today offers many options, from low-end ferrous metal models to high-tech aluminum platforms with hydraulic brakes. The choice of a particular model depends not only on the budget, but also on the type of car you have, the weight of the car you have. boat-engine The wrong equipment can cause problems on the road and even lead to emergency situations when braking.
In this article, we will discuss in detail all the nuances that must be considered before buying. galvanized steel Often preferably painted, how to calculate the permissible load and whether it is worth registering the trailer device at the traffic police. competent approach will allow you to save money and enjoy rest on the water, rather than repairing equipment.
Types of trailers: what material to choose for the water element
The first thing the buyer faces is the choice of frame material and padding, the main options are two: steel (black or galvanized) and aluminum alloys. Black metal But contact with salt water or just regular trips to water quickly destroy the protective layer. If you plan to use the equipment often, you should immediately consider more durable materials.
Hot galvanizing It's a process that makes steel virtually immune to corrosion for years to come. Trailers like this cost more, but they take decades to live, even when stored outside. Aluminum, in turn, is lighter than steel and also doesn't rust, but it's less twistable and much more expensive to manufacture. For heavy boats with powerful engines, aluminum can be too soft.
⚠️ Warning: When buying a trailer made of ferrous metal be sure to check the thickness of the metal frame. thin-wall profile (less than 2 mm) quickly deforms under the weight of the boat and motor, which will lead to disruption of geometry and problems with the chassis.
It is also important to pay attention to the coating of the pawns (spoons) on which the boat lies. They can be wooden (require regular replacement and processing), plastic or made of polyurethaneThe latter option is most preferable, as it does not absorb moisture and does not scratch PVC tubes even in the presence of sand.
Calculation of load capacity and dimensions
To buy a suitable trailer for a PVC boat, it is not enough to know only the length of the vessel. The critical parameter is the total weight of the equipped boat, along with the engine, battery, gas tank and additional equipment. Many beginners make the mistake of buying back-to-back equipment by weight, which leads to axle overload and rapid failure. spring Or torsion.
The length of the breather must be considered. Too short a breather can cause maneuvering problems, and it will not allow the weight to be correctly distributed to the axle of the car. The optimal option is when the load on the bulb is 10-15% of the total weight of the trailer, which ensures stability of movement and prevents the trailer from wagging at high speed.
For clarity, we give a table of correspondence of the length of the boat and the size of the trailer platform:
| Boat length (m) | Recommended platform length (m) | Max. total mass of trailer (kg) | Typical axis |
|---|---|---|---|
| up to 3.5 | 4.0 - 4.5 | 500 | monoaxial |
| 3.6 - 4.5 | 5.0 - 5.5 | 500 - 750 | Uniaxial reinforced |
| 4.6 - 5.5 | 6.0 - 6.5 | 750 - 1200 | Uniaxial/Tandem |
| more than 5.5 | 6.5 | 1200 | Tandem (two axes) |
When calculating the dimensions, remember to overhangs. The boat should not go beyond the platform more than 2 meters from the rear, otherwise you will need to install an additional sign "Big cargo" and lighting fixtures. Also check whether the structure will fit in your garage or in the parking space.
Chassis and braking systems
Traffic safety is directly dependent on the quality of the chassis, and in the budget segment, there are often domestically produced axles or Chinese analogues, which require regular maintenance: lubrication of bearings, checking the nut tightening and condition of the nuts. shock absorbersMore expensive models are equipped with AL-KO or BPW axles, which are highly reliable and have automatic brake adjustment.
If your trailer is over 750 kg in weight, it must be fitted with a brake system by traffic regulations. Light trailers (up to 750 kg) do not require brakes, but they make life easier for the driver, especially when driving in mountainous terrain or in the rain. There are inertial brakes that are activated when the brake is pressed, and electric brakes that require a special controller to be installed in the cabin.
Do you need brakes on the trailer up to 750 kg?
Brakes on a trailer with a gross weight of up to 750 kg are not mandatory for traffic rules. However, if you plan to often carry heavy loads or move on difficult roads, the presence of a braking system (even a simple inertial) will significantly improve safety and reduce the braking distance of the train.
Wheels are also important. Boat trailers often use smaller diameter wheels (R13), which reduces the center of gravity. It is important to monitor tire pressure and the presence of a spare wheel. A punched camera away from civilization can ruin all rest.
Lighting equipment and electricians
A proper light alarm is not only a requirement of the law, but also a guarantee of your safety on the road. Standard connection scheme includes dimensions, turn signals, stop lights and fog lights. When buying a used trailer or building yourself, there are often problems with the "mass".
Modern cars with multiplex wiring can work incorrectly with conventional lamp trailers, emitting errors on the dashboard. universal It takes the current directly from the battery, protecting the car's electronics from overload.
- 🔌 Connection connector: The most common 7-pin outlet (euro) is used, but American or older cars may have different standards.
- 💡 Type of lamp: LED lights consume less energy, shine brighter and last longer, but are sensitive to voltage surges.
- 🛡️ Leakproofness: Check for rubber seals on the headlights so that water does not get inside when the boat is descent.
The wiring must be laid inside the frame or in protective corrugated sleeves. Open wires will quickly rub, oxidize from salt water and cause lighting to fail. Use only copper wire with a cross section of at least 1.5 mm2 to power the lights.
Registration in the traffic police and necessary documents
Buying a trailer is half the battle, you have to register it to go on public roads legally, and it's similar to registering a car, but it has its own specifications, and you need a vehicle passport or an electronic PTS, a sales contract and a check for the state fee.
The most important document is the certificate of conformity. Registration is impossible without it. When buying from hand, make sure that the previous owner has all the documents, otherwise you will have to go through a complex certification procedure yourself, which can cost more than the trailer itself.
☑️ Documents for registration
The cost of the state duty for the issuance of numbers and registration certificates is indexed annually, so it is better to specify the actual amounts on the official website of the traffic police or in the office. Do not forget that driving a car with an unregistered trailer is equated to driving without a license and entails a fine and placing equipment in a parking lot.
Service and preparation for the season
The long life of the machinery depends on proper care. After each trip, especially on salt water, the trailer must be thoroughly washed with fresh water. Salt is the main enemy of metal, even galvanized. Pay special attention to the hubs of wheels and brakes.
Once a year, it is recommended to conduct a full maintenance: check the puff of all bolt joints, lubricate the bearings of the hubs (using special lubricants that withstand high temperatures and water), inspect the condition of springs and shock absorbers. A burst leaf of springs can cause a serious accident.
If you can't, you can use a high-quality, thick-tissue, impregnated awning, and cheap polyethylene will create a greenhouse effect, which will accelerate the corrosion of metal parts and the rotting of wooden elements in the pads.
Frequently Asked Questions (FAQ)
Do I need an E category to drive a car with a boat trailer?
Category E (BE) is required if the total mass of the trailer exceeds 750 kg, OR if the total mass of the car and trailer exceeds 3,500 kg. For most light boat trailers (up to 750 kg), the usual category B is sufficient.
Can I carry other cargoes on the boat trailer?
Technically, if size and weight allow, but the lozenges are designed to support the hull of the boat, and the transport of building materials or motorcycles can damage the coating of the lozenges or deform the frame if the load is point.
How to load the boat on the trailer alone?
Use a long-tether winch. Drive as close as possible to the water with the nose of the trailer, unload the boat with the engine, then tighten it with a winch, controlling the position on the paddles. For heavy boats, there are special guides (roller keels) that make it easier to load.
What to do if the trailer body is rusted?
The rust must be cleaned to metal (with a Bulgarian brush or sandblast), the surface degreased and the rust transducer coated, then the soil and finishing coating are applied, and in critical cases (through corrosion) new elements are welded.
Buying a quality trailer is an investment in safety and comfort. Don't skimp on chassis and corrosion protection, as repairing or replacing the axle will cost more than the initial overpayment for a reliable model.
