Buying a 320 centimeter inflatable boat is an important step for any angler or water lover, but transporting such a vessel on the roof of a passenger car is often a real headache. Many owners ignore the need to purchase specialized equipment, relying on rails and ropes, which creates dangerous situations on the road and can lead to damage to expensive property. Trailer under the PVC boat 320 It is not just an accessory, but a technically sound solution that ensures the safety of your vessel during long-term transportation.
Choosing the right model requires careful technical consideration, as standard solutions for large boats may be redundant or incompatible with compact equipment. In this article, we will discuss in detail how to choose the optimal padding or keel solution for your hull length to avoid problems with centering and wind load.
It is important to understand that the dimensions of the trailer directly affect maneuverability during parking and the possibility of storing it in the garage. Uniaxial options It is considered the gold standard for boats of this class, providing the perfect balance between the carrying capacity and the ease of driving.
Criteria for the selection of dimensions and type of pawn
The main parameter for equipment selection is the length of the lodging, which must exceed the length of the hull of the vessel by 10-15 centimeters on each side for reliable fixation. For a boat with a length of 320 cm, the optimal length of the trailer frame will be from 340 to 350 cm, which will allow you to install the nose stops and locking elements without risk of damage to the cylinders.
There are two main types of hull support: keel and padding. The keel option involves a central beam on which the keel of the vessel rests, which provides excellent centering, but requires a rigid keel in the design of the boat.
The false-piece type uses wide soft supports covering the sides, which is ideal for inflatable models with soft bottom or plywood floorboard. Log trailer distributes the load evenly throughout the area of the cylinders, minimizing the risk of scuffing or puncture during a long road along the highway.
When choosing, consider the adjustability of the supports, as this will allow you to transport boats of different sizes or change the configuration of the cargo. Universality of design often becomes a decisive factor when buying, allowing you to save on the upgrade budget in the future.
Technical specifications and load capacity
The weight of the PVC 320 boat assembled with engine, tank and equipment rarely exceeds 200-250 kilograms, so massive structures with a tonne reserve will be an unnecessary waste of money. It is enough to choose a model with a nominal carrying capacity of up to 400-500 kg, which will provide the necessary safety margin and durability of the chassis.
Special attention should be paid to the type of bearings in the hubs of wheels. tapered with high-quality oil seals that can withstand short-term immersion in water when the boat is launched into the water without immediate lubrication.
Tires on these trailers are usually installed with a diameter of R13 or R12, which is the standard for passenger trailers. It is important to check the tire load index, which must correspond to the total mass of the trailer in running order to take into account the weight of the device itself.
| Parameter | Optimal value for PVC 320 | Permissible range |
|---|---|---|
| Length of losoment | 3400 mm | 3300 - 3600 mm |
| Load capacity | 400 kg | 300 - 750 kg |
| Diameter of wheels | R13 | R12 - R13 |
| Type of axis | monoaxial | monoaxial |
| Unladen mass | 100 kg | 80 - 150 kg |
You should not chase for maximum load capacity, as increasing the trailer's own weight reduces the payload of your car. Lightweight aluminum frames are preferable to steel frames, as they are not susceptible to corrosion and weigh easier.
Legislative requirements and registration in GIMS
The issue of registration of trailers in traffic police (now functions are often transferred to the GIMS or remain in traffic police depending on the region and type of vehicle) is one of the most discussed. According to the current legislation of the Russian Federation, trailers with a maximum permissible weight of up to 750 kg do not require a separate license plate if they are used in a passenger car.
However, if the total weight of the trailer exceeds 750 kg, or if you plan to use it with vehicles of category "B", the rules may change. 750 kilogramsThis will eliminate the need for annual inspection and obtaining a separate passport of the vehicle (PSD).
⚠️ Attention: Even if the trailer does not require registration with the traffic police, it must be equipped with reflectors, catafots and a serviceable light alarm. The absence of stop lights of the trailer device is equivalent to a vehicle failure.
When buying, be sure to require the seller to complete the package of documents: the purchase contract, check and passport of a self-propelled vehicle (PSM) or a certificate of safety of the structure. Without these documents, you will not be able to prove ownership of the trailer in the case of checking documents on the road or when leaving the country.
Do I need a checkup for a lightweight trailer?
Trailers of up to 3,500 kg owned by natural persons do not require a periodic technical inspection (diagnostic chart) unless they are used for commercial transport, but the condition of the chassis and lighting devices must allow safe operation.
Materials of manufacture: steel against aluminum
The choice between a steel and aluminum trailer often comes down to a balance between price and durability. Steel structures coated with hot galvanizing are cheaper and have high strength, but require constant monitoring of the integrity of the coating.
Aluminum frames do not rust, which is critical for equipment that is in constant contact with salt or fresh water. Aluminum alloy lighter steel, which allows you to increase the payload, but the cost of such a solution can be 1.5-2 times higher.
If you plan to store the trailer in the open air, aluminum will be the best investment, because it does not require annual painting and fight against corrosion, steel will require careful anti-corrosion treatment of all welds and regular updating of the protective layer.
After each salt water trip, be sure to wash the chassis and trailer frame with fresh water under pressure to remove salt residues, even if the trailer is aluminum.
Pay attention to the quality of welds and paint. On steel models, the powder paint should be uniform, without bubbles and chips, which will instantly become centers of rust formation.
Instructions for safe loading and fixing
The proper loading of the boat on the trailer is a guarantee of safety on the road, the process begins with the preparation of the site: it should be flat, and the trailer's breather is located horizontally or with a slight tilt back for ease of arrival.
Move the trailer to the water or flat area so that the trailer axis is just ahead of the boat's center of gravity, and this will prevent the nose from picking up when lifting.
☑️ Checklist before departure
Use the winch to smoothly tighten the boat to the paddles, controlling the position of the bow strap. After installing the vessel, you must securely fix it with ratchet belts passing through special rings or handles on the sides.
Sequence of fixation:Nose belt (main belt).
2. auxiliary slings (left and starboard).
3. Insurance cable on the breather.
4. Test the tension of all elements.
Don't forget. tetherThis cable, which must be mounted on the frame of the car separately from the main coupling device, in the event of a failure or uncoupling of the porch, will prevent the trailer from being pulled off and an emergency situation arises.
Operation, storage and maintenance of the trailer
The durability of your equipment depends on the quality of service. After each trip, especially off-road or in dust conditions, it is recommended to lubricate the moving parts of the hinges and check the tension of the bolt joints.
Store the trailer in a dry room or under an awning. If this is not possible, use special covers for wheels and frames to protect the rubber from ultraviolet light and metal from precipitation.
⚠️ Warning: Never leave a trailer with a loaded boat in the parking lot for a long time (month or more). Constant pressure on the same points of the pads can lead to deformation of PVC tubes and the appearance of "crawls" of the material.
Check the electrical wiring regularly, especially the location of the cable's entry into the lights. Vibration when driving often results in insulation rubbing and short circuiting, which can disable the electrician of the car.
Regular lubrication of hub bearings and checking the tire pressure prolong the life of the trailer by 5-7 years even with active operation.
Frequently Asked Questions (FAQ)
Do I need to register a trailer weighing 300 kg in the traffic police?
No, according to the current rules, trailers with a maximum permissible weight of up to 750 kg, owned by individuals, are not subject to mandatory registration with the traffic police and do not require the receipt of license plates if used as part of a passenger car.
Can I carry a 350 cm long boat on such a trailer?
Technically possible, if the width of the vessel allows, but this will be a violation of the rules for the carriage of oversized cargo, since the bow and stern will protrude beyond the dimensions of more than 1 meter (total). For a boat 350 cm need a trailer with paddles of the appropriate length.
What speed is allowed when driving with a trailer?
For cars with a trailer outside settlements, the maximum speed is 90 km / h, on highways - 110 km / h, in settlements - 60 km / h Exceeding these standards can lead to loss of control due to the effect of "wagging".
Do I need a special class of rights to tow a trailer?
For trailers weighing up to 750 kg, the usual category “B” suffices. If the mass of the trailer exceeds 750 kg but the combined mass of the vehicle and trailer does not exceed 3,500 kg, category “B” is also retained.
