Transporting a small vessel to the launch site is not just a logistical task, but a process that requires strict compliance with safety and law. Many owners of small inflatable or compact aluminum boats wonder whether a standard truck trailer designed for cargo, rather than a specialized trailer, can be used for this purpose.
Ignoring the nuances of fixation conveyor Unlike keel yachts, light boats often lack a rigid keel, which requires a special approach to load distribution. In this article, we will discuss in detail the technical and legal aspects of transporting a boat in a conventional trailer.
Selection of suitable trailer and assessment of dimensions
The first step is to analyze the technical specifications of your trailerStandard models, such as MZSA or similar, often have sides that can interfere with the installation of boats with a wide transom or a hard keel. loading capacity The trailer must exceed the weight of the boat with the engine and equipment, but not be excessive, so as not to disturb the stability of the coupling.
The key is the length of the lodgings or the possibility of installing them. transportationIt is recommended to remove the sides or use models with folding sides. For inflatable boats, it is critical that there are no sharp edges inside the body, which can damage cylinders when vibrating.
The dimensions of the cargo must not exceed the body more than 1 meter at the rear, unless additional lighting devices and signs are installed. Exceeding the width of the vehicle by more than 2.55 meters requires special permission, which is rare for a conventional boat in a trailer, but control the width of the vehicle. transportable necessary.
⚠️ Note: The use of a trailer with a damaged spring system or faulty electrical wiring is strictly prohibited, as vibration when moving can destroy the structure of the boat even with reliable mounting.
Some owners prefer to use lodgeThis allows you to turn a universal trailer into a boat trailer in a minimum of time, but such tuning requires welding and accurate calculation of the center of gravity.
Technical requirements for the hull anchorage
The reliability of fixation is the guarantee of safe operation The basic rule is that the boat should not be able to move in either the longitudinal or transom direction, using sling-arm belts that are sufficiently tensile, and conventional sling-bag belts on the roof may not withstand dynamic loads under heavy braking.
In case of installation of an inflatable PVC boat The ideal option is to use a wooden flooring or a dense carpet that will protect the bottom from abrasion. Inflate the cylinders to the working pressure in front of the road is not recommended - when heated in the sun, the pressure inside can increase, which will lead to deformation.
The belt anchorage points should be on the reinforced sections of the boat: transom, rim bolts or special hinges. balloon You can't, because it can damage it, and it's better to use soft pads or to use a belt under the bottom if the trailer design allows.
- 🔒 Use a minimum of 4 belts: two on the nose and two on the aft for even distribution of forces.
- 🛡️ Apply protective covers or dense fabric in the places of contact of the belts with the boat hull.
- ⚖️ Check the straps after the first 5-10 kilometers of the journey, as the material may stretch slightly.
For hard-bottomed aluminum boats, the requirements are even stricter. quiltIf the boat is only on the transom and nose, a deflection can form in the middle, which over time will lead to cracks in the metal.
If you are carrying a boat with an engine installed, be sure to remove it or securely lock it in an upright position to avoid breaking the lower unit from vibration.
Features of transportation of inflatable PVC boats
Inflatable boats have a unique elasticity, which simultaneously simplifies and complicates them. On the one hand, they can take the form of a lodging, on the other, any sharp object in the trailer becomes a potential threat, and before laying it, make sure that the body is free of nails, chips or sticking bolts.
Temperature plays a major role. In summer, in direct sunlight, the dark color of the cylinders promotes rapid heating. The air inside expands, and if the boat is inflated "before the bell", the risk of seams rupturing increases. Experienced water engineers recommend pumping the boat in front of the road only 70-80% of the working pressure, pumping it already on the water.
Firming transom-wheel It also requires attention. If it's mounted on a transom, it can serve as an additional support point, but only if the belt design anticipates this, and often the wheel is removed and placed inside the cockpit so as not to increase the overall height.
⚠️ Warning: Never place heavy objects (anchors, batteries) in the cockpit of an inflated boat without additional fixation, as when braking they can penetrate the soft bottom or shift the center of gravity.
And the wind load is important, because an inflatable boat, even if it's upside down, it works like a sail. When you're side winding or you're overtaking a truck by a road train, the trailer with the boat can pull to the side. In such conditions, speed is a mandatory safety requirement.
☑️ Pre-departure checks
Transportation of aluminum and rigid housings
Metal boats, such as Kazanka, Ob Unlike PVC, metal does not forgive errors at the points of support. The main pressure should be on the keel and zygomatic lines. The use of conventional onboard trailers for such vessels is possible only with the presence (custom) of support bars.
The problem with conventional metal boat trailers is the height of the sides, and if the sides are high, you can't lower the boat deep, and it will lie on the edges, which is dangerous when shaking, and the way out is to install additional wooden or rubber supports that distribute the load over a larger area. case.
When strap-mounted, it is important not to overpower the side, metal can deform under the pressure of the screed tape, especially if the boat is thin-walled, and it is recommended to use wide belts and put soft pads made of porous rubber or felt under them.
| Parameter | PVC Boats | Aluminum boats | Plastic boats |
|---|---|---|---|
| Type of support | Uniform plane | Point (keel/spangouts) | Logins in shape |
| Risk of overheating | High (tear) | Missing. | Medium (deformation) |
| Sensitivity to impacts | Low. | Medium (dents) | High (cracks) |
| Wind sailing | High. | Low. | Medium |
For heavy metal boats, it is critical hanging If the main mass is shifted back, the breather will pick up, putting a dangerous load on the car's farcreet and impairing handling, the optimal ratio is 60% of the weight on the front of the trailer.
How do you protect the sides from belts?
Use the cuts of the garden hose that are cut along the way, put them on the belt at the site of the boat, and it's a cheap and effective way to prevent dents and scratches on paint or metal.
Legal aspects and requirements of the SDA
The law clearly regulates the rules of carriage of goods, according to traffic rules, the cargo should not restrict the driver's view, close lights and license plates. If the boat in the trailer closes the taillights of the trailer or the car, this is a violation for which it is provided for. penalty.
If the dimensions of the cargo (boats with trailer) are more than 1 meter outside the vehicle, the sign “Large cargo” shall be installed. At night or in conditions of insufficient visibility, the protruding parts shall be marked with retroreflectors (flickers) in front white, rear red.
The speed limit for a trailer-based vehicle is also limited: on roads outside built-up areas, passenger cars with a trailer are allowed to travel at a speed of no more than 90 km/h, and on motorways - no more than 110 km/h (unless signs set a lower limit).
- 🚦 Make sure that the trailer license plate is readable and not covered by the boat attachment elements.
- 💡 Check all the turn signals and stop lights of the trailer before each departure.
- 📏 Measure the total length of the train: If it exceeds 20 meters (which is rare for boats, but possibly with long catamarans), special permits are required.
A category of rights may be required to drive a vehicle with a trailer with a permissible maximum mass exceeding 750 kg. «E» (e.g. B+E) if the combined mass of the vehicle and trailer exceeds 3,500 kg. Category B is usually sufficient for light trailers (up to 750 kg).
Traffic rules and safety on the road
Driving with a trailer, especially with high and sailing loads, requires a change in driving style. The braking distance is significantly increased, so the distance to the vehicle in front must be kept 1.5-2 times longer than usual.
When driving on the highway, you should avoid deep tracks and pits. The impact of the trailer's wheel is transmitted directly to the frame and therefore to the boat's hull. When cornering, you should take into account that the trailer "cuts" the trajectory by going inside the turn closer to the side of the road, this is especially dangerous on narrow roads near the water.
Wind is the main enemy in boat transport. Side gusts can rock the trailer very hard. If you feel that the car is starting to "drag" from side to side, you should smoothly reduce the speed without making sudden movements with the steering wheel. In the conditions of a storm warning, you should refrain from traveling.
⚠️ Warning: When reversing with a trailer, remember that the trajectory of the trailer and the car are opposite. A sharp steering wheel turn can lead to folding of the train or rollover.
Regular stops are mandatory. Every 100-150 km, it is recommended to stop at the side of the road (in a safe place) and visually check the condition of the fastenings, the pressure in the trailer tires and the integrity of the trailer. cargoVibration on the track can weaken even well-tightened knots.
Safety of transportation depends not only on the strength of the belts, but also on the adaptation of the driving style: smooth acceleration, braking and cornering is critical.
Frequently Asked Questions (FAQ)
Do I need to register a trailer for the transportation of a boat to the traffic police?
Yes, if the total weight of the trailer exceeds 75 kg, it is subject to mandatory registration with the traffic police and must have a license plate. For light boat trailers, this is a standard procedure requiring a PTS or a sales contract.
Can I transport a boat with an engine installed?
Technically, it is possible if the motor is securely fixed and does not exceed the permissible load on the transom and trailer, but experts recommend removing the motor to reduce the center of gravity and prevent damage to the lower unit from vibration and impacts on rough roads.
What is the maximum speed to be followed?
According to traffic rules, for a passenger car with a trailer, the maximum speed outside settlements is 90 km / h, on highways - 110 km / h Exceeding these limits is dangerous because of the risk of resonant pumping of the trailer.
How to secure the boat if there are no special bolts?
In this case, the belts are passed under the bottom of the boat (if the design allows) or cover the body in the reinforcement areas (transom, timber). Be sure to use soft pads so that the belt does not rub the material or paintwork when stretched.
Do I need a “Sized Cargo” sign for a regular boat?
The sign is required if the load is more than 1 meter in size. For most inflatable and small aluminum boats, fully fit in the trailer body or not projecting beyond it by more than 1 meter, this sign is not mandatory, but desirable to attract the attention of other drivers.
