Choosing the right way to transport a boat is not just a matter of convenience, but a critical task to ensure safety on the road.
An improperly fixed boat can cause a serious accident or damage an expensive vessel hull during movement.
The modern market offers many solutions, from compact roof systems for small PVC boats to massive trailer platforms for heavy boats.
In this article, we will discuss all the nuances in detail so that you can choose the ideal one. boat-car for your needs.
You will learn about the technical features of various designs, methods of fixing them on the car and the rules that dictate GIMS and traffic rules.
Proper preparation for transportation will save you nerves, time and money for repairing the car or the boat itself.
The main types of constructions for the transport of boats
The first thing that the owner of water transport faces is the choice between a roof trunk and a trailer.
Roof structures are designed for relatively lightweight vessels, such as motor-assembled inflatable PVC boats or small plastic canoes.
They are attached directly to the car rails or to special adapters installed in the doorway.
Trailer systems are the choice for owners of heavy aluminum boats, boats and large inflatable vessels with powerful engines.
Such boat-trailer It allows you to transport the boat along with the fuel tank and additional equipment without overloading the roof of the car.
It is important to note that driving with a trailer often requires category "E" in the driver's license if the total mass exceeds 750 kg.
There are also universal trailerwhich can be transformed into different types of cargo.
They are equipped with adjustable padding supports or roller systems that facilitate loading.
The choice of design type directly depends on the dimensions of your boat and the carrying capacity of the car.
Technical specifications and load capacity
When choosing a trunk, the key parameter is the permissible load.
For roof systems, this figure rarely exceeds 100 kg in statics and is much less in dynamics (when moving).
It must be strictly observed loading capacityThe suffix specified by the car manufacturer, as exceeding the limit can lead to deformation of the roof or even detachment of the structure.
How to calculate the dynamic load?
Dynamic load is the weight that the roof of a car can withstand in motion, which is usually about 30% of the static load, for example, if the static is 100 kg, then it is safe to carry no more than 30-40 kg in motion, including the weight of the crossbars themselves.
Trailer systems have a much larger margin of safety.
Modern models are equipped brake-system inertial type, which are triggered when braking the car.
This is critical for heavy boats, as the inertia at a stop can be great.
Pay attention to the material of the frame.
Galvanized steel resists corrosion in salt water better than painted steel.
Aluminum alloys are lighter, but may be less durable under extreme twisting loads.
Materials of manufacture and protection of the boat hull
Contact of the boat with the elements of the trunk should be as gentle as possible.
For PVC boats, the absence of sharp edges that can damage cylinders is critical.
Specialty use is made laying-piece with carpet or rubber rollers.
Carpet paddings provide excellent fixation and protection from scratches, but they absorb moisture.
If you do not dry such a trunk after descent into the water, the carpet may begin to rot or become covered with mold.
Roller systems, in turn, facilitate self-loading: the boat easily rolls down the rollers when lifting out of the water.
Use silicone spray to treat rubber rollers before the season – this will prevent them from drying out and cracking in the sun, and will also make it easier for the case to slip.
Metal parts of the structure must have a reliable anti-corrosion coating.
This is especially true for fishing lovers on the sea coasts, where salt mist corrodes the usual metal in a matter of weeks.
Check the quality of welds and the presence of plugs on the ends of the pipes so that water does not get inside the profiles.
Instructions for installation and fastening on the car
Installation of the luggage system requires care and compliance with the sequence of actions.
First, you need to install crossbars on the roof of the car, strictly following the instructions for your car model.
Then the frame itself or the pawns for the boat are mounted on the crossbars.
☑️ Pre-departure checks
The boat is fastened with the help of belts with a ratchet mechanism.
Never use elastic harnesses ("rubbers") to fix the craft - they do not provide rigid fixation.
The belts should be stretched evenly, without distortions that can lead to a shift in the center of gravity.
Be sure to use a safety cable or chain connecting the trailer to the body of the car.
This is a requirement of traffic rules and common sense logic: if the main coupling device fails, the cable will hold the trailer on the road.
Check to see if position lamps The trailers were well read and well read by other participants.
Rules of safe transportation and traffic
Transportation of a boat on a roof or trailer is regulated by traffic rules.
The cargo shall not extend beyond the dimensions of the vehicle by more than 1 meter in front and rear, and by more than 0.4 meters on the sides.
If the boat is long and protrudes beyond the limits of the car, its end should be marked with a flag or a shield with red and white stripes.
⚠️ Warning: Excess dimensions without special permits and signs "large-sized cargo" entails a fine and a ban on further movement.
The speed limit for trailer towing is usually limited to 90 km/h on country roads and 60 km/h in populated areas.
Move with such a load should be smooth, avoiding sharp jerks and braking.
The braking distance of the car increases, so the distance to the vehicle in front should be kept twice as much as the usual.
Pay special attention to the windy weather.
The sailing capacity of the inflatable boat on the roof is high, and gusts of side wind can destabilize the car.
In such conditions, it is recommended to reduce speed and hold the steering wheel tighter.
Comparative table: Roof vs Trailer
To finally decide on the choice, compare the main parameters of the two types of systems in the table.
This will help you weigh the pros and cons for your particular case.
| Parameter | Roof trunk | Trailer system |
|---|---|---|
| Load capacity | up to 80-100 kg | up to 3,000 kg and more |
| Facility of loading | It requires a climb to a height. | Booting from water or winch |
| Influence on the car | Increases fuel consumption, noise | Requires category "E", stopping distance |
| Cost | Below. | Higher. |
| Storage | He's taking up a seat in the garage. | It requires parking space. |
For frequent operation and heavy boats, the trailer is an alternative, while the roof is ideal for rare trips to a light PVC boat.
System care and preparation for winter storage
After the navigation is over, the trunk requires maintenance.
Metal elements must be thoroughly washed with fresh water, especially if the operation was in salt water.
Then you should lubricate all moving parts: locks, hinges, axles of the trailer wheels.
Rubber seals and mats of lodgings are better removed and removed in a dry room.
In the cold, rubber bluffs and can crack when loaded.
Check the condition of the belts: if they have scuffs or broken, they must be replaced before the next season.
⚠️ Warning: Do not keep the belts in a compressed state (with tight ratchets) - this leads to loss of elasticity and strength of the fabric.
Ball head trailer canned with a special lubricant or put on a protective cap.
This will prevent the coupling device from oxidizing and jamming in the spring.
Regular care will extend the service life luggage-system for years to come.
Frequently Asked Questions (FAQ)
Do I need to register a trailer for a boat in the traffic police?
Yes, if the total weight of the trailer exceeds 75 kg, it must be registered with the traffic police, get a license plate and have a vehicle passport (PTS). For light trailers up to 75 kg registration is not required, but the purchase documents are better to carry with you.
Can I transport a boat with an engine installed?
Technically, it's possible, but it's not recommended. The motor puts extra stress on the boat's shaking trawler, and it also increases the center of gravity of the entire structure, and the residue of fuel in the tank can create a fire hazard, and it's better to remove the engine and transport it separately.
Which belt is better: with a ratchet or a tensioner?
For a reliable fixation of the boat, especially on the roof or in the back, it is better to use belts with a ratchet mechanism (rattle), which allows you to create and hold much more tension than simple tensioners with hooks, eliminating sagging in the way.
How to protect a PVC boat from abrasion on the trunk?
Use special protective covers on cylinders or lay soft fabric / cardboard in the places of contact with belts, there are special linings on belts with a soft inner surface, regularly check that there is no sand or dirt under the belts.
Is it allowed to drive backwards with a trailer?
Reversing with a trailer is only permitted in exceptional cases where other maneuvers cannot perform the task (for example, when parking), and provided complete safety. However, in practice it is a complex maneuver that requires skill, since the trailer turns in the opposite direction from the rotation of the wheels of the car.
