Choosing a reliable platform for transporting a boat is a task that every owner of a small vessel faces sooner or later. In the Russian market, for many years, one of the leaders remains the products of the Kama plant, in particular, the model with the index C. This unit has become a kind of de facto standard for owners of inflatable PVC boats and small metal boats due to its availability and maintainability.
However, despite the popularity, the design has its own features, which must be taken into account at the stage of purchase or in the process of operation. Load capacity The C model is 400 kg, which allows boats up to 4.5 meters long with an engine and additional equipment installed. Unlike heavier counterparts, this option requires less effort when maneuvering manually, but also requires more careful attention to weight distribution.
Many drivers are wondering about the compatibility of specific boat models with this trailer. It is important to understand that the dimensions of the pad are not always perfectly matched with the contours of the hull, which may require improvements, which is why a detailed analysis of technical nuances will help to avoid problems on the road and extend the life of both the trailer and the boat being transported.
Technical specifications and design features
Constructively Kama S It is a single-axle trailer with a frame welded from a profile pipe, and the main difference from models with an H or M index is that there is no own side, which makes it versatile for the installation of various types of pads or keel rollers. Overall width The platform is 1,850 mm, which is ideally suited to the traffic requirements for traffic without special permits. The length of the cargo platform allows for the placement of vessels up to 4.5 meters in length, but for the transport of longer objects will require special permission.
The suspension is spring-based, a time-tested solution that provides a good load capacity, but has its own nuances in driving comfort, and springs require periodic maintenance, especially in domestic road conditions. Chassis It is equipped with wheels with a diameter of 13 inches, which is the standard for this class of equipment.
⚠️ Note: General springs are often not rigid enough to fully load, which can lead to the penetration of the suspension on the bumps. Owners are advised to assess the state of depreciation immediately after purchase and, if necessary, install additional sheets or replace the springs with more rigid analogues from GAZelle.
Lighting equipment is based on classic taillights, and wiring is often mounted in an open way, making it vulnerable to mechanical damage and moisture. Electrical circuitry standard for domestic trailers, but the quality of the insulation of the connections leaves much to be desired, requiring the owner to additional seal the contacts immediately after purchase.
Compatibility with PVC boats and aluminum boats
The main purpose of the Model C is to transport inflatable boats, and because there is no hardboard, PVC boat owners can install soft lozenges that will not damage the cylinders when vibrating. PVC boat The absence of sharp edges in the contact area is critical, and the Kama frame makes it easy to organize such protection using carpeting or rubber profiles.
The situation is more complicated with aluminum boats: the metal hull requires more rigid fixation and precise matching of the points of support with the power set of the vessel. Staff beds are often not suitable for the specific contours of some boats, such as Kazanka or Salute, in which cases individual fitting of the supports or complete reworking of the fixation system is necessary.
When choosing a configuration, you should consider the weight of the engine. outboardIf you do not, you need to move the center of gravity closer to the drawer, otherwise you will put a lot of stress on the coupling device of the car, which can lead to instability on the track.
Necessary tuning and modifications DIY
The practice shows that buying a "bare" trailer is only the beginning of the journey. Most owners face the need to improve comfort and safety. The first step is usually the modernization of lighting devices. The regular wiring is thin and quickly oxidized, so experienced craftsmen recommend completely going through the electrics, using a copper cable with a cross section of at least 1.5 square meters. mm and sealed connectors.
The second important step is the installation of a quality awning. Staff awnings are often made of a thin material that quickly burns out and tears. To protect the boat from dust, dirt and tree branches, it is better to order a tailored case of reinforced fabric, taking into account the attributes installed on the sides (anchor, paddle, sonar).
- 🔧 Frame reinforcement: Installation of additional scarves in welding sites to prevent cracks during prolonged operation.
- 🔦 Lighting: Replacing lamp lights with LED modules for better visibility and durability.
- 🛡️ Defense: Installation of splashers and plastic wings to protect the car body from flying dirt from under the wheels.
⚠️ Warning: When welding on the frame, be sure to remove the rubber breakers and suspension elements. Heating the metal can lead to the melting of rubber and loss of properties by springs.
The breather is particularly noteworthy, because many users have added a backup to the back wheel or anchor, which allows you to de-load the space in the car, but requires careful balance calculations. sticker It is experiencing maximum loads during braking.
Instructions for Season Preparation and Conservation
Proper preparation of the trailer for use is a guarantee that in the high season you will not be left on the side of the road. Spring maintenance begins with a visual inspection of the frame for corrosion. Even if the product is galvanized, the welding sites can be vulnerable, and if rust spots are found, they must be cleaned to metal, treated with a converter and painted over.
☑️ Spring checklist of the owner
The chassis is then maintained. The hubs need to be lubricated using a special bearing lubricant. If you notice a backlash of the wheel or a hum while driving, the bearings should be replaced preventively. Stage knots on Kama C are quite simple and repairable, spare parts for them are available in any car store.
At the end of the season, before putting it for winter storage, the structure should be thoroughly washed and dried. Metal elements are recommended to be treated with an anti-corrosion compound. It is better to store the trailer under a canopy or in the garage, having previously removed the wheels and lifting the frame on the stands to unload springs and tires.
specifications comparison table
To understand the place of the model C in the product line of the Kama plant, it is useful to compare its parameters with other common modifications, which will help determine whether this option is suitable for you, or whether it is worth considering models with sides or larger payloads.
| Parameter | Kama C (Unsided) | Kama 8113 (Airborne) | MZSA (Analogue) |
|---|---|---|---|
| Load capacity | 400 kg | 400 kg | 400-500 kg |
| Length of platform | 2970 mm | 2020 mm | 3000 mm |
| Platform width | 1850 mm | 1600 mm | 1850 mm |
| Type of suspension | Resorbed | Resorbed | Resorbed |
| Unloaded mass | 135 kg | 145 kg | 150 kg |
As you can see from the table, the Model C beats the long-bearing version, which is critical for long-haul loads, but the lack of a side requires a more responsible approach to locking cargo with screed belts.
Legal aspects and rules of operation
The operation of a category E trailer requires compliance with certain traffic rules, especially speed limits. 90 km/hOn the roads outside of the settlements, 70 km/hExceeding these limits is not only fraught with fines, but also the loss of stability of the road train.
If the boat or cargo is carried beyond the dimensions of the trailer by more than 1 meter in front or behind, or more than 0.4 meters on the sides, you need to mark the cargo with special signs and lanterns. red-lightAnd the front is white.
Do I need Category E rights for the Kama C trailer?
For driving a vehicle with a trailer of category "E" (B+E), rights are required only if the permissible maximum mass of the trailer exceeds 750 kg, OR if the total permissible mass of the road train exceeds 3,500 kg. Since the mass of the Kama C with a load does not usually exceed 1150 kg (400 kg load + 135 kg trailer itself), the usual rights of category "B" are sufficient to drive, provided that the mass of the car allows to pull such a weight.
Regular check of the wheel attachment is a mandatory procedure. Before each exit, it is recommended to check the tightening of the wheel nuts and stepladder springs. Vibration on the road contributes to the self-unwinding of the threaded joints, so using a thread locker or periodic monitoring with a dynamometer key will not be superfluous.
Frequently Asked Questions (FAQ)
What is the maximum size of the boat to be installed on the trailer Kama C?
The optimal length of the boat is from 3.5 to 4.5 meters. Theoretically, you can accommodate a longer vessel, but then the nose and stern will act out of dimensions, which will require the installation of additional marker lights and traffic signs.
Do I need to register a trailer in the traffic police?
Yes, trailers weighing more than 750 kg are subject to registration with the traffic police and require their own license plate. Since the curb weight of Kama C is about 135 kg, and the total weight of 535 kg, registration is mandatory. For trailers with a gross weight of up to 750 kg registration is not required, but Kama C has it above this threshold.
Can I install a winch on this model?
Yes, you can have a manual or electric winch on the breather, which will make it much easier to load a heavy motorized boat, but you need to strengthen the winch mounting position, because the regular hole may not withstand traction when loading a heavy boat.
How to distribute the weight of the boat on the platform?
The centre of gravity of the loaded trailer should be slightly ahead of the wheel axis (approximately 10-15% of the mass should press on the farcrow ball). If the boat is mounted too far back, the trailer will wag on the road. If too far ahead, the rear axle of the car will overload.
In conclusion, it is worth noting that Kama C is one of the most repairable models on the marketThe right approach to tuning and maintenance will allow you to use this trailer for decades, ensuring that your boat is delivered safely to the water.
