Transportation of inflatable watercraft is not just a matter of convenience, but a necessity dictated by logistics and physics. Trailer for PVC boat It is becoming an indispensable tool when it comes to long-distance travel or regular trips to water bodies, and unlike metal counterparts, rubber vessels require careful transport, but they have a much lower weight, which expands the range of technical solutions available.
Choosing the right platform is always a compromise between budget, frequency of use and size of your platform. The boat + engine + equipment setErrors in the planning phase can lead to damage to cylinders or traffic problems, so the issue should be approached systematically. In this article, we will discuss all the nuances, from the design of the frame to the legal subtleties.
Types of trailer devices for inflatable boats
The market offers several design solutions, each with its own advantages. single-axle trailer Lodges (braces) are bucket-like stops covered with a special carpet that prevents slipping and protects PVC fabric from abrasion, an ideal choice for those who value reliability of fixation and ease of maintenance.
An alternative is roller systems, where the boat relies on a series of rotating rollers. Roller trailers They allow faster loading and unloading, because the boat can easily roll down by inertia, but they require a perfectly aligned frame, otherwise the load will be unevenly distributed, which can be critical for long journeys along the highway.
- 🚤 Login - maximum protection of the bottom, ideal for long trips and storage.
- 🛞 Roller - facilitate descent and rise, suitable for frequent trips to one pond.
- 🏗️ Combined - a combination of rollers in the nose and passements in the aft for balance.
- 🛠️ Homemade – budget option, requiring deep knowledge of the design and welding.
⚠️ Attention: Using cheap rollers without bearings or with low rubber quality can lead to jamming of the wheels when loading, which can damage the transom of the boat.
Calculation of load capacity and dimensions
The main mistake of beginners is the choice of a trailer "back-to-back" along the length of the boat. Dimensions of trailer Not only should the length of the cylinder be taken into account, but the removal of the transom motor, as well as the possible installation of the keel arch. If you plan to carry a boat in an inflated state with the engine installed, the length of the platform should exceed the length of the vessel by at least 20-30 cm on each side.
The second critical parameter is loading capacityIt is calculated as the sum of the weight of the boat, the engine, the fuel tank, the anchor gear and the weight of the trailer itself. It should be remembered that passport load capacity is the limit value at which the chassis resource (springs, hubs) is consumed faster.
For clarity, consider the dependence of the choice of trailer on the class of the boat:
| PVC class boat | Length (m) | Weight of the set with the engine (kg) | Recommended load capacity of trailer (kg) |
|---|---|---|---|
| Compact (2 seats) | 2.8 - 3.2 | 150 | 300 - 400 |
| Average (3-4 places) | 3.5 - 3.9 | 200 - 300 | 500 - 600 |
| Full-size (4+ seats) | 4.2 - 4.8 | 350 - 500 | 750+ |
| Heavy (hard bottom) | 4.5+ | 500+ | 1000+ |
Keep a load capacity margin of at least 30 percent, which will prolong the life of hub bearings and springs, especially when driving on dirt roads to the water.
Design features and materials
The basis of any quality device is a frame. Most often used. profile-pipe Zinc coating protects the metal from corrosion, which is critical for equipment in constant contact with water. Painted frames require regular tinting of chips, otherwise rust can appear after the first season of active use.
The chassis is also noteworthy, and light PVC boats often use spring or torsion axles. Torsion suspension It's considered more modern: it doesn't require maintenance, it doesn't rust inside the casings, it gives you a better smoothness on the track, but when it breaks, it requires replacing the entire knot, whereas the spring can be partially replaced.
The important element is the breather. It can be A-shaped or T-shaped. A-shaped provides better stability on the road, especially at high speeds, but takes up more storage space. T-shaped is more compact, but can be less stable when fully loaded with a heavy motor.
Secrets of durability of the chassis
To keep the bearings of the hubs lasting longer, before each winter preservation, it is recommended to remove the caps and check the lubricant. The use of lithium lubricants with molybdenum disulfide significantly increases the resource of the unit in aquatic conditions.
Legal aspects and requirements of GIMS
Registration often makes water-powered vehicles stupid. registration Requires trailers with a gross mass of more than 750 kg. If your trailer is lighter, category "E" numbers and licenses are not required, category "B" in the driving license is sufficient.
However, there are nuances about lighting and dimensions, and even if the trailer does not require registration, it must be in good working order: turn signals, stop lights and dimensions, and the absence of reflectors or broken wiring is a guaranteed fine when meeting with the traffic police inspector.
⚠️ Attention: Transportation of a motorized boat protruding more than 1 meter without a red flag or light designation in the dark is a traffic violation.
For trailers with a gross mass of up to 750 kg, it is sufficient to be equipped according to the manufacturer's requirements, and the presence of a vehicle passport (VP) or a sales cheque indicating the model is mandatory in case of inspection.
☑️ Checking before leaving for the track
Safe loading and fastening rules
Correct fixation of the vessel is a guarantee of safety on the road. Transportation of the boat It requires at least two or three straps with a ratchet mechanism, one belt fixes the nose (through a ring or a crowbar), the rest - the body in the cockpit and transom, the use of conventional ropes is unacceptable, because they tend to stretch and weaken with vibration.
When loading, it is important to ensure that the keel of the boat lies strictly in the center of the frame. Distortion can cause the boat to start cruising from side to side at speed, creating a dangerous swing. For boats with an inflated keel (HPD), it is especially important to use high-sided lobes to lock the vessel in a horizontal position.
It is better to remove the motor during transportation, if the construction of the trailer and the weight of the engine allows. outboard It creates a lever that can damage the transom when you shake a lot, and if you can't remove it, use transom wheels and extra stops.
The golden rule is that the boat should be pressed against the pad throughout the contact area, and gaps between the balloon and the support are unacceptable, as they lead to local overload and abrasion of the fabric.
Care and maintenance in the offseason
After the navigation, the trailer requires mandatory preservation, salt, sand and silt, trapped in the knots, can destroy metal and bearings in one winter, the first thing you need to thoroughly wash the frame and chassis with fresh water, removing all contamination.
Then you should lubricate all the movable joints: breather, coupling lock, wheel hubs. Rubber elements (carpets, breakers) are recommended to treat with a protective composition against ultraviolet light to prevent cracking.
- 🧼 Wash the frame thoroughly from salt and dirt.
- 🛢️ Replace or supplement the lubricant in the hubs.
- 🔧 Check the tightening of all bolt connections.
- 🌡️ Keep the trailer in a dry room or under an awning raised above the ground.
Regular maintenance will avoid costly repairs and ensure that the equipment is ready for the beginning of next season.
Do I need to remove the wheels from the trailer for the winter?
Removing the wheels is not necessary, but it is advisable to lift the trailer to the stands to unload the tires and springs, this will prevent the appearance of "flat spots" on the rubber and loss of elasticity by springs.
Can I carry a boat with raised arcs on a trailer?
Technically, you can, if the dimensions allow and the awnings are securely secured, but this greatly increases the sailing and the risk of damage to the structure on the highway, it is better to transport in a disassembled form.
What is the life of the carpet paving?
When active operation (20-30 trips per season), the carpet lasts 2-3 years. After that, the pile wears off, and there is a risk of damage to PVC.
Is it allowed to exceed the dimensions of the trailer during transportation?
Exceeding the width of more than 2.55 m requires special permission and escort. The length of the trailer with a load should not exceed 20 meters (for road trains), but for passenger cars, restrictions are usually limited to 12 meters (including cars).
