Planning for water transport is rarely limited to the boat and the motor itself, and water-engineers often forget about the critical link in the chain: the vehicle to deliver the boat to the water. Trailer selection For a PVC boat requires a careful approach, since not only the convenience of the descent depends on it, but also the legal purity of your trips.
Inflatable vessels have their own design features that dictate specific requirements for lodging. Unlike rigid aluminium or fiberglass hulls, PVC is afraid of sharp edges, but it is very cushioning. louvre-trailers Often become a more preferred choice over classic roller systems, although the latter have the right to life when set up properly.
In this article, we will discuss in detail all the nuances that will help you not make a mistake with your choice. You will learn how to calculate the necessary parameters, what types of ramps exist and why full weight is a key indicator for compliance with the rules of the road.
Key parameters of choice: dimensions and load capacity
The first thing to start looking for the perfect chassis is to measure the dimensions of your boat in running order, and it's important to understand that the platform should be longer than the length of the balloon so that the nose and the transom don't hang down critically. Load capacity The trailer must exceed the total weight of the boat, motor, battery, tank and additional equipment with a margin of about 20-30%.
If you plan to transport a boat assembled with the engine installed, make sure that the dimensions do not exceed the allowed limits for driving without special permits. In Russia, the width of the vehicle with the cargo should not exceed the width of the vehicle with the cargo. 2.55 meters.
Also, look at the clearance and the angle of the exit. The gentle sandy beaches that are common in many bodies of water require special elongated breaths or ramps. If you change launch sites often, the versatility of the design will come to the fore. If you miscalculate these parameters, you may not be able to enter the water on a particular descent.
- 📏 The exact length of the balloon inflated with a margin of 10-15 cm on each side.
- ⚖️ The total weight of all equipment, including keel, stringers and anchor.
- 🚗 The traction coupling device (TCC) of your car and its maximum load.
- 🌊 The type of coastline where the main descent is planned (concrete, sand, clay).
When choosing, pay attention to the availability regulation Boats from different manufacturers and even from different years of production of the same model can have different bottom geometry, and the ability to move the supports back and forth or change their height will allow you to perfectly distribute the load on the keel and cylinders, avoiding local stress points.
Types of pads: rollers against bars
The eternal water-motor debate: which is better for PVC rollers or wooden bars? Roller systems are traditionally considered more versatile, because they allow you to easily roll a boat by inertia. However, for inflatable boats, they pose a hidden threat. Even new, high-quality rollers wear out over time, and through them can pass metal spokes or sharp edges that can damage the boat. PVC cylinder.
Lodges in the form of bars covered with a special carpet (carpet) provide a greater contact area, this distributes the weight of the boat more evenly, which is especially important for long transportation along the highway. Carpet coating also protects the sides from istyrabrasion on the splasher and frame. However, such systems require more accurate fitting to the shape of the bottom.
⚠️ Attention: When using a roller system, regularly check the integrity of the rubber on the rollers. The appearance of cracks or protruding metal parts requires immediate replacement, otherwise it is only a matter of time before the cylinder punctures against the metal axis.
There are also combinations where the nose is roller-based to make it easier to load, and the main platform is a carpet guide, which combines ease of loading and safety of transportation. When choosing a material to coat bars, choose Marino or analogues that are resistant to ultraviolet light and salt water.
The secret of the durability of carpeting
To make the carpeting of the pads last longer, after each trip in salt water, be sure to wash it with fresh water. The salt is cryalized in the fibers and acts as an abrasive, rubbing the threads when vibrating on the go. It is also useful once a season to treat the coating with a water-repellent spray.
Legal aspects and categories of rights
Registration and the need for a category of rights are often confusing: Under current legislation, special rights are not required to drive a vehicle with a category B trailer (car trailers) if certain conditions are met. maximum mass allowed (RMM) of the trailer as specified in its PTS.
If the trailer's RMM does not exceed 750 kg, the category "B" in the driver's rights is sufficient regardless of the mass of the car. If the mass of the trailer is more than 750 kg, it may exceed the mass of the car without load, but the total authorized mass of the road train should not exceed 3,500 kg. Otherwise, the category "BE" will be required.
| Parameter | Meaning | Requirement of rights | Is registration required? |
|---|---|---|---|
| Weight up to 750 kg | Any (within TSU) | Category B | Yes, if the mass is > 750 kg |
| Mass > 750 kg | Amount per car ≤ 3500 kg | Category B | Yes. |
| Mass > 750 kg | Amount per car > 3,500 kg | Category BE | Yes. |
| Weight up to 750 kg (old PTS) | Indicated in PTS | Category B | No (on the old PTS) |
Registration at the traffic police is mandatory for all trailers with a permissible maximum mass of more than 750 kg. For such models, you get a full PTS and license plate. For trailers lighter than 750 kg, registration is not required, but the presence of a self-propelled vehicle passport (PSM) or a purchase agreement is necessary to confirm the legality of ownership during the inspection.
The main rule: if the PTS of the trailer is specified permitted weight of 750 kg, you have every right not to register it in the traffic police and do not receive numbers, even if structurally it can carry more.
Frame design and anticorrosion protection
Because the trailer is in constant contact with aggressive aquatic environments, the quality of corrosion protection comes to the fore. The most common and affordable option is hot galvanizing. This method provides reliable protection for many years, even when operating in salt water. However, it is worth remembering that welds are a weak point, and their condition must be controlled.
Painted frames, even powder paint, are significantly inferior to zinc in durability. Paint quickly cracks off from the impact of pebbles on the descent, and the metal begins to rust. If you choose the painted option, be prepared for regular maintenance: rust stripping and coloring. Aluminum frames are free of corrosion problems, but they are significantly more expensive and less repairable in the field.
Note the breathable structure. For larger boats, a double-beam frame is preferred, providing better stability and weight distribution. Single-beam structures ("ridges") are lighter and cheaper, but they can bend under a heavy motor if they do not have sufficient gain. Frame rigidity It directly affects the safety of traffic on the road.
- 🛡️ Hot galvanizing is the best choice for long years of service without rust.
- 🔩 The quality of welded seams should be uniform, without slag and burns.
- 🚛 The presence of reinforced breathed for the transportation of heavy engines (from 50 hp).
- 💡 Possibility of installing a winch with the correct thrust angle for safe loading.
After every trip to the sea or in salt water, be sure to thoroughly wash the trailer with fresh water, especially the chassis and hubs. The salt destroys the metal and bearings even through micro-scratches in the zinc layer.
Chassis: axles, bearings and wheels
The reliability of the chassis is a guarantee that you will get to and from the water without excesses. Most boat trailers are equipped with a single axle, which is quite enough for light and medium PVC boats. However, for heavy complexes (boat + powerful motor + equipment), it is better to consider two-axle options that hold the road more stable and are safer when the clutch breaks.
The key is hubs and bearings. Choose models with high-quality gums that protect the lubricant from water. There are hubs with a lubrication system without disassembly, which makes maintenance much easier. Regularly checking the heating of the hubs after the trip is a good habit to detect problems at an early stage.
⚠️ Warning: Never lower a fully deflated trailer with wheels into the water unless the hubs have a special sealing system. Sharp cooling of hot brake drums (if any) or simply getting water through the sapoon when cooling will lead to water being sucked in and bearings quickly out of order.
Wheel size also matters. Smaller wheels (R10, R12) create more off-road problems and lower speed on the track. Long-distance wheels are preferable to R13 diameters. Remember to check tire pressure before every trip, as under-performing tires can lead to cord failure and explosion at high speed.
☑️ Annual chassis maintenance
Additional equipment and tuning
The standard trailer is often minimalist. To improve comfort and safety, consider purchasing additional accessories. A winch with a stainless steel cable or synthetic rope will make it much easier to load a heavy boat alone. A cable made of ordinary steel quickly rusts and can stain your hands and boat.
Lighting is another critical node: Hermetic LED lights last longer and are better able to withstand vibration and immersion than classic incandescent lights. Make sure the wiring is laid inside the frame or is reliably protected by corrugated to prevent wires from intercepting when maneuvering.
For long-distance travelers, it may be helpful to install a spare wheel, even if it is not designed initially. A puncture away from civilization can turn a vacation into a nightmare. Also consider installing a wing with a motor lock so as not to carry it separately in the trunk.
Do I need a break brake on the trailer?
Brake system (inertial or electric) is mandatory for trailers with a gross mass of more than 750 kg (according to UNECE regulations, requirements may vary in Russia, but safety is above all). For light trailers with PVC boats, brakes are usually not put, since the weight of the load is small. However, if you plan to carry a heavy boat with a powerful engine at high speeds, the presence of brakes will significantly reduce the braking distance of the car.
How to properly fasten the boat on the trailer?
The boat should be fixed with a bow stop through the winch, and you should also use belts that are thrown through the cylinders and attached to the sides of the trailer, which will prevent the boat from jumping on the bumps, and the transom stops should also be tightened, but without fanaticism, so as not to deform the transom.
In conclusion, it is worth noting that the ideal trailer for PVC boats is a load model with hot galvanizing and adjustable platformThis configuration provides the best balance between the safety of an expensive inflatable body, the ease of use and the durability of the vehicle itself. Don't skimp on the quality of the chassis, because it depends on the safety of you and your boat on the road.
FAQ: Frequently asked questions
Do I need to register a trailer for a PVC boat in the traffic police?
Registration is mandatory if the permitted maximum mass of the trailer (specified in the PTS) exceeds 750 kg. If the weight is less than or equal to 750 kg, registration is not required, it is enough to have a contract of sale.
Can I carry a fully assembled boat over long distances?
However, it is recommended to check the tension of the belts and the pressure in the cylinders periodically (every 200-300 km), as it can change on the track due to temperature fluctuations and vibration.
What category of rights is required for a trailer weighing 900 kg?
If the total permissible mass of the vehicle and trailer does not exceed 3,500 kg, category B is sufficient. If it exceeds, category BE is required.
What are the dangers of roller trailers for PVC boats?
The main danger is the risk of damage to the cylinders on the sharp edges of the rollers when they are worn or improperly adjusted, as well as point pressure, which can deform the keel during prolonged parking.
