Owning a 350 centimeter inflatable boat is a great start to getting out on the big water, but transporting a boat on the roof of a car quickly ceases to be convenient. trailer-drivenThis solution not only protects the back and roof of the car, but also allows the safe transport of a full set of equipment, including the motor, anchor and fishing gear.
Choosing the right carriage for this length requires an understanding of the technical nuances, because standard solutions may not be suitable for an inflatable hull. PVC boats We need special support from the side and keel to avoid deformation when driving on the highway, and then we will discuss in detail what to look for when buying or manufacturing, and also discuss the legal aspects of operation.
Criteria for the choice of trailer for a boat 350 cm
The first thing to pay attention to is loading capacity A 350 cm motorized boat and battery can weigh between 150 and 250 kg in running order, so the safety margin should be substantial. You should not take a trailer with the minimum permissible load, as this will lead to rapid fatigue of the metal and deformation of the breathed.
The second important parameter is the type of lodging. roller Or combined guides that minimize friction on the bottom: Hard plywood or uncoated metal paddings can damage cylinders when vibrating, especially if they get hit by sand or small pebbles.
⚠️ Warning: When choosing a trailer, make sure that the gauge is the same as the size of your boat. Too narrow track will lead to an advantage and dangerous roll when cornering, and too wide can exceed the dimensions of the car.
It's critically important. paint-quality Because the trailer is in constant contact with water, salt and sand, the normal enamel will quickly peel off, and hot galvanizing or sandblasting powder painting is considered the best solution.
- 🚗 Dimensions: The length of the platform should be 20-30 cm longer than the length of the boat to accommodate the transom wheel.
- ⚖️ Weight: The dry weight of the trailer shall not exceed half the mass of the towing vehicle.
- 💨 Aerodynamics: Pay attention to the height of the boat landing; too high profile increases fuel consumption.
Design features and types of pawns
The basis of your boat's safety is the hull support system. PVC 350 The keel bed takes over the bulk of the weight, spreading it along the center line, which prevents the bottom from sagging, and the onboard elements record the position of the vessel, preventing it from moving left or right in side winds or road rolls.
There are two main types of pads: carpet and rubber. Carpet is great for scratch protection, but it absorbs water, dirt and can rot if not dried. Rubber rollers are more practical in this regard, they are easy to wash and do not accumulate moisture, but are more expensive and require more accurate height adjustment.
The secret to setting up pads
The logon should be the same as the boat, and if you lift the bow of the boat behind the bow poop, it should be sliding smoothly on the keel, not hanging on the transom or the nose, and this will distribute the load evenly.
It is important to check regularly laying-up Vibration on the road can weaken bolt joints, which will distort the entire structure. Use growers or carving fixers when you build them to avoid trouble along the way.
Chassis: springs, wheels and brakes
The chassis of the trailer is under enormous loads, especially given the state of the roads to the reservoirs. For a light boat 350 cm is usually enough one axis, but the quality of springs plays a key role. Ressors shall be designed to weigh slightly more than the total mass of the trailer with the boat, in order to prevent the suspension from breaking through the pits.
Wheels are often the weakest link in cheap models. The optimal diameter for such dimensions is R13, although there are also R12. The main thing is to monitor the pressure in the tires and the presence of a spare wheel, because it is difficult to find the right "roll" on the track. The hubs must be protected from water, otherwise the bearings will quickly fail.
According to the regulations, if the total mass of the trailer exceeds 750 kg, it must be equipped with a vehicle. brakeHowever, for a 350 cm motor boat, the total weight rarely reaches this threshold, remaining within the 400-500 kg range, allowing for unbrake trailers (Category B).
| Parameter | Optimal value | Minimum requirement |
|---|---|---|
| Load capacity | 500-600 kg | 350 kg |
| Diameter of wheels | R13 | R12 |
| Type of suspension | Resorbed | Resorbed |
| Lighting devices | LEDs (diodes) | Filament lamps |
Use LED lights instead of incandescent lights, they are not afraid of vibration, consume less energy and last 5-10 times longer, which is critical for a trailer that often shakes on a primer.
Necessary tuning and modifications DIY
Factory trailers often require improvement for comfortable operation with PVC boatThe most useful modification is the squirrel wheel, which allows one person to easily roll a heavy motorized boat onto a platform without having to lift it manually.
Another important element is wingsThe standard wings are often too short or narrow, causing mud and water to fly onto the boats and back of the car. Splash-elongated wings solve this problem by keeping the craft clean when driving on wet roads.
☑️ Checklist for trailer completion
It is not superfluous to arrange a storage place. anchor-fail You can weld extra brackets or use the nets of the slaves that are stretched between the sides to securely fix the soft bags while moving.
Rules of registration in GIMS and legal aspects
The issue of registration of trailers in GIMS (State Inspectorate for small vessels) is often controversial. According to the current legislation of the Russian Federation, registration is subject only to those trailers whose total weight exceeds 750 kg. Since the trailer for a boat 350 cm usually weighs about 150-200 kg, and the boat with the engine - up to 300 kg, the total weight rarely reaches the threshold of 750 kg.
However, if you are buying a heavy-duty trailer or planning to carry very heavy equipment, this may change. The technical data sheet (PCM) always states the maximum permissible weight. If this figure is more than 750 kg, registration is mandatory, even if you are carrying a light boat.
⚠️ Note: When buying a trailer from hand, be sure to require a PSM (passport of a self-propelled car). Without this document, it will be impossible to register a trailer with the GIMS, and you risk getting a fine at the first check.
For driving a car with a trailer of category "B" normal driving license is sufficient, if the total permissible mass of the trailer does not exceed 3500 kg.
If the total weight of your trailer (specified in the PSM) is less than 750 kg, register it in GIMS and receive numbers is not necessary - it is enough to have a sales contract and PSM.
Operation, storage and winter conservation
Proper storage extends the life of the trailer for many years, and after each unloading of the boat, especially from salt water, you need to carefully freshwaterSalt is an aggressive corrosive agent and can destroy even galvanized coatings in one season.
For winter storage, it is better to put the trailer on the stands, removing the load from the springs, this will prevent them from "tiring" and sagging. The wheels also need to raise or pump up the pressure to avoid flat spots on the rubber from long standing.
Check your condition regularly wiringContacts in the socket and headlights are often oxidized. Using a special lubricant for contacts (for example, lithium-based) will help protect the connections from moisture and corrosion.
- 🧼 Wash the trailer after each trip to the sea.
- 🛡️ Lubricate rubbing parts and bearings before the season.
- 🌡️ Keep the trailer in a dry place or under the awning.
Frequently Asked Questions (FAQ)
Do I need to register a trailer for a PVC 350 boat in GIMS?
Not if the total weight of the trailer (as specified in the PSM) does not exceed 750 kg. For boats with a length of 350 cm this rule is met in 95% of cases.
What is the maximum length of the boat suitable for a single-axle trailer?
Single-axle trailers are usually designed for boats up to 5-6 meters long. For PVC boats 350 cm, the uniaxial design is optimal, as it is lighter, more maneuverable and cheaper to maintain than biaxial counterparts.
Can I carry a metal boat on a PVC trailer?
Technically, if size and weight allow, but PVC lobes are soft and may not support the weight of the metal case, and sharp angles of the metal will damage the rollers, and it is better to use specialized lobes or gaskets.
