Owning a 380 cm inflatable boat offers a huge opportunity for a fisherman or tourist, but transporting such a boat on the trunk of a car often becomes a challenge. The weight of a set of hull, engine, fuel tank and equipment can reach 100-120 kg, which creates a significant load on the body and requires regular removal and installation of cargo. boat-trailerThis not only facilitates the process of descent, but also provides safety when driving on the highway.
Choosing the right trailer for a 3.8-meter boat is not just about buying an iron frame, it’s about investing in the durability of your gear and the comfort of your trips. The wrong trailer can be a source of constant problems, from rubbing cylinders to breaking the balance when towing. In this article, we’ll take a look at all the aspects of the choice, the technical details and the rules of operation, so that your trip to the pond starts with positive emotions, not with fighting equipment.
Types of trailers for inflatable boats
The trailer market offers several design solutions, and for the PVC 380, it is important to choose the modification that will ensure the safety of the soft sides. The main difference lies in the type of padding - elements on which the boat's hull relies. Loginmental The models are standard for inflatable boats, as they provide spot-based but reliable fixation without the risk of puncture, and unlike them, keel roller systems are designed primarily for rigid hulls and can damage PVC when parked or shaken for long periods.
Special attention should be paid to the material of the pawns themselves. For use in fresh water, support with a coating of special plastic or rubber that does not scratch the bottom is great. If you plan to go out to salt water bodies or often leave the trailer on the shore, it is better to consider options with pawns from the bottom of the car. stainless steel Or processed aluminum, although they require more careful handling of cylinders, and it is important that the supports have rounded edges and are securely attached to the frame.
⚠️ Attention: It is strictly forbidden to use lodging trailers with sharp metal edges or damaged coating for transporting PVC boats. Any roughness can cause damage to expensive material when vibrating.
Trailers are also divided by frame type: welded or collapsible. Welded design has greater rigidity and reliability, excluding backlashes in joints, which is critical for maintaining geometry when driving. Collapsible models are more compact when stored, but require regular check of fasteners. For the boat 380, which is often used with powerful engines, the rigidity of the frame is a priority to avoid resonance fluctuations.
Calculation of load capacity and dimensions
The 380 cm long boat, assembled, has a considerable weight to consider when choosing a trailer. The base weight of the boat itself can vary from 60 to 90 kg depending on the density of the material and the design of the bottom, to which you need to add the weight of the outboard motor (from 25 to 60 kg), fuel tank, anchor, equipment and the trailer itself. Load capacity The selected trailer must exceed the total weight of the cargo with a margin of at least 15-20%.
The dimensions of the platform are also key: the length of the trailer should be such that the bow of the boat (foreshoot) and the transom go beyond the supports, but are securely fixed. Too short platform will cause the transom to hang, which will create a dangerous lever when braking, and too long will complicate maneuvering and parking. The optimal length of the platform for a boat 3.8 m is from 4.2 to 4.5 meters.
Don't forget the ground clearance and the angle of the exit. PVC boats have a soft bottom that bends under its own weight when lifting out of the water. If the angle of entry on the trailer is too steep, the center of gravity will shift, and the boat may slip or deform. In such cases, it is recommended to use a winch with a long cable for a smooth puff.
| Parameter | Boat 380 (light) | Boat 380 (heavy) | Required trailer stock |
|---|---|---|---|
| Boat mass | ~65 kg | ~95 kg | - |
| Motor + gear | ~40 kg | ~70 kg | - |
| Total weight of cargo | ~105 kg | ~165 kg | Min 200 kg. |
| Recommended length | 4.2 m m m | 4.5 m | +10-15% |
When calculating the load capacity, always add the weight of the boat, engine, fuel, anchor and equipment, and the safety margin should be at least 20% of the total weight for safe operation.
Manufacture materials and anticorrosion protection
Constant contact with water, especially salt water, and road reagents makes corrosion the main enemy of the boat trailer. The most common and affordable solution is powder-painted steel. However, as practice shows, even quality paint eventually breaks off from stones and gravel, opening the way to rust. For fresh water bodies and rare use, this option is acceptable, but requires constant monitoring and coloring.
The gold standard for water technology is hot-dipIn this process, the steel frame is immersed in molten zinc, which creates a layer on the surface that provides electrochemical protection for the metal. Even if the coating is damaged before scratch, zinc will continue to protect the steel around the damage, sacrificing itself. Trailers with this treatment last for decades without losing strength, making them economically viable in the long run.
Aluminum trailers are less common and cost much more, and their main advantage is absolute resistance to corrosion and light weight. However, aluminum is less durable on the kink when hitting concrete slips and more difficult to repair. For most owners of PVC 380 boats, galvanized steel, combining strength, durability and reasonable price, remains the best choice.
⚠️ Warning: After each trip to the sea, be sure to thoroughly wash the trailer with fresh water under pressure. salt left in the hidden cavities of the frame can destroy even galvanized coating in one season.
Set: winch, light and kilblock
The basic equipment of the trailer is often minimal, so for comfortable operation of the boat 380 may require re-equipment. The central element of the tightening system is a winch. For this size of the boat, a mechanical winch with a traction force of 500-750 kg is quite enough. It is important that it is equipped with a reliable ratchet mechanism that prevents the cable from re-unfolding. The cable itself is better to choose a synthetic one - it does not rust and is safer for the hands than a steel cable.
The keelblock is the front support that the boat's nose rests on, and it has to be adjustable in height and angle to exactly replicate the keeliness of your boat. An improperly exposed kilblock will cause the boat to lie unevenly on the frame, causing skewedness and increased friction during transportation, and adjusting by loosening the bolts and moving the support along the frame.
Lighting equipment is a must for legal travel on public roads. The standard set includes dimensions, stop lights and direction indicators. For boat trailers, the tightness of lights (IP67 protection class and above) is important, since they are regularly submerged in water when descent. LED optics are preferred over lamp optics due to lower vibration sensitivity and lower power consumption.

Rules for safe loading and transportation
The process of loading a PVC boat onto a trailer requires a certain sequence of actions to avoid damage to property and injuries. First, the trailer is parked on a slip so that the rear lobe goes underwater, but the front part remains dry. The boat is brought to the trailer, and the bow is drawn by winch or manually onto the kilblock. Only after a reliable fixation of the nose can the hull begin to align along the sides.
The boat is fastened by a braking belt. The boat 380 usually requires two or three pairs of belts. It is important not to over-tighten the belts so as not to deform the cylinders, but also to ensure that there is no backlash. The engine is better to take off and stow in the boat or carry separately, as vibration can damage the boat's lower unit or transomb.
When driving on the highway, you should take into account the increased dimensions and braking distance of the car. The speed with a trailer should not exceed 90 km / h, and in poor road conditions - 60 km / h. Particular attention should be paid to the passage of corners, since the trailer has the property of "cutting" the trajectory, and sharp maneuvers can lead to a rollover.
What if the boat is on its side?
If you notice that the boat has shifted during the movement, you should immediately stop in a safe place. Relax all belts, align the body manually, check the position of the kilblock and re-tighten the cross-cross mounts.
Maintenance and storage
Regular maintenance prolongs the life of the trailer and ensures safety on the road. After each unloading, especially in salt water, the trailer must be thoroughly washed with fresh water. Pay special attention to the hubs of the wheels - they require periodic lubrication of bearings and inspection of the boulders. Bearings are recommended to be lubricated with special water-resistant lubrication (for example, lithium-based) every 5-10 thousand km of run or once a season.
Keep the trailer best under a canopy or in a garage to protect rubber elements and lodgings from ultraviolet light, which destroys plastic and rubber. If storage takes place outside, it is recommended to cover the lodgings with cloth or remove them. Before placing them for winter storage, it is better to raise the wheels on the stands to relieve the load from the tires and prevent the appearance of "flat" seats.
Periodically check the tightening of all bolt joints of the frame. Vibration when driving on uneven roads can weaken even tightly twisted nuts. Using a thread fixer or counternuts will help avoid problems with unwinding the structural elements during the trip to the fishing site.
To lubricate the bearings of the hubs, use only specialized water-resistant lubricants (NLGI marking 2 or higher). Conventional solidol is quickly washed out by water, which will lead to a jamming of the wheel on the track.
Do I need to remove the motor when transporting on a trailer?
Yes, for PVC 380 boats, it is strongly recommended to remove the outboard motor, the weight of the motor puts additional stress on the transom when driving over irregularities, which can lead to cracks in the place of the lower unit mount, and the removed motor is safer and more convenient to transport inside the boat or in the trunk.
What is the maximum permissible weight of the motor for a trailer without brakes?
In most countries, including the Russian Federation, the presence of a braking system on the trailer is required if its total weight exceeds 750 kg. For a boat 380 with a light engine, the total weight rarely reaches this limit, but if you plan to use heavy motors (more than 50 hp) and a large amount of equipment, it is worth considering a trailer with a braking system or inertia brake.
Can a trailer for a boat 380 be used to carry a smaller boat?
Yes, you can, but you need to adjust the position of the pads and the kilblock. If the boat is much smaller (for example, 320 cm), it may not reach the rear supports, which will cause the stern to sag, in which case you need to move the pads closer to the drawer or use additional supports to ensure an even distribution of weight.
