Transportation of the boat to the place of descent to the water often becomes the first test for the owner, because the correctness of preparation depends not only on the safety of your boat, but also the safety of other participants in the movement. Transportation of a boat on the roof of a car It is one of the most popular methods, especially for small-sized inflatable or aluminum models, which cannot be delivered to the water by trailer due to narrow access roads.
But just tying a boat to the trunk is half the battle, because high-speed aerodynamics and vibrations can be a cruel joke to an inexperienced driver. In this article, we will go through all the nuances of choosing the type of trunk to the final check of the knots before going to the track.
Ignoring the basic rules of fixation can lead to an emergency, so the process must be approached with maximum responsibility and attention to detail.
Choosing the Right Type of Baggage System
The first and most important step is to find equipment that can withstand the weight of the boat and not damage the body of the car. The market offers many solutions, but for the transport of boats most often used for transporting the boat. railing or specialized brackets that repeat the contours of the body.
For lightweight PVC inflatable boats, standard crossbars are often sufficient if they have sufficient carrying capacity. In the case of heavier aluminum or wooden boats, it is advisable to use V-shaped holders that rigidly lock the hull and prevent it from being displaced by the wind.
When choosing a material, consider the material of manufacture: aluminum is lighter, but steel is stronger, although it is susceptible to corrosion when in contact with salt water. It is also important to consider the length of the crossbars - they must protrude beyond the dimensions of the boat to ensure reliable fixation of slings, but not go beyond the legal limits of the width of the vehicle.
- 🚗 Cross-sections - suitable for light inflatable boats in covers, require the use of soft linings.
- 🛶 V-shaped brackets - ideal for rigid housings, provide better aerodynamics and stability.
- 🔩 Combined systems - allow you to transport the boat along with other equipment, but more difficult to install.
⚠️ Before buying, be sure to check the maximum static and dynamic load on the roof of your car in the instructions for use, as exceeding the limit can lead to deformation of the body.
Preparation of the boat and the car for transportation
The preparation process begins long before the road and requires careful approach to every detail. First of all, the boat must be completely clear of sand, silt and water, as excess moisture significantly increases weight and can cause corrosion of metal elements in transit.
If you're transporting PVCMake sure it is pumped to working pressure or, conversely, slightly lowered depending on the manufacturer's recommendations, to avoid rupturing the seams from temperature changes and pressure at altitude.
☑️ Preparation for the flight
The car also requires preparation: check the reliability of the mounting of the crossbars themselves to the rails or bodywork. All screws and clamps should be tightened with the force recommended by the luggage system manufacturer. It is not superfluous to lubricate rubbing surfaces with silicone grease to prevent creaks and material on a long trip.
- 🧼 Carefully wash the bottom of the boat so that dirt does not fly to oncoming cars.
- 🔍 Look at this. junction and other hinged elements - it is better to remove them or securely fix them.
- 🌡️ Check the condition of the belts and slings for cracks, scuffs and stretching.
Pay special attention to protecting the paintwork of the car. Use special soft linings or dense fabric in the areas of contact with the slings to avoid scratches from vibration.
Technology of correct installation and fixation
The most important thing is to put the boat in the prepared place, and to minimize air resistance and reduce noise, it is recommended to place the boat upside down if the hull design allows, and this position also protects the interior from rain and dust.
When installing, use the assistance of a second person to avoid damaging the sides of the roof edge or the trunk. The center of gravity of the boat should be approximately midway between the front and rear crossbars, which will ensure an even distribution of the load on the axle of the car.
Nuances of laying keel boats
If your boat has a pronounced keel, the use of simple crossbars can lead to spot pressure and deformation of the bottom. In this case, be sure to use V-shaped brackets or lay a soft roller along the keel to distribute weight.
For fixation, use only specialized transport-belt With a ratchet mechanism or reliable knots if ropes are used, synthetic belts are preferred because they do not absorb water and are less prone to rotting than natural materials.
| Type of attachment | Materials | Advantages | Deficiencies |
|---|---|---|---|
| Fork-belts | polyester | Fast fixation, high tension | Risk of dragging and damage to the side |
| Rolling stations | Polypropylene/Nylon | Cheap, lack of metal elements | Requires knitting skills, may weaken |
| Cargo nets | Rubber/Tissue | Additional top-fixing | They are not the primary fixture. |
When tightening your belts, watch for force: they should keep the boat “dead”, but do not push the cylinders or thin metal to a state of deformation. After the initial tightening, be sure to take a few steps back and assess the symmetry of the position of the vessel relative to the axis of the car.
Use of safety ropes and additional measures
Even the most reliable basic fixation does not give 100% guarantee in emergency braking or sharp maneuver, so the use of safety cables (brakes) is a mandatory safety requirement. These cables are attached to the bow and aft parts of the boat and are fixed for structural elements of the car - towing hooks or special eyelets.
The bow delay prevents the boat from being jacked up by the oncoming air flow, which can create lift and rip the boat off the trunk. The aft delay, in turn, prevents the boat from moving forward under sharp braking, protecting the rear window and trunk lid from damage.
To fasten the safety cables, use carbines with a lock to exclude their spontaneous unbuttoning from vibration, and be sure to wrap the place of contact of the cable with the body with a soft cloth.
The safety cables should be fitted so that they are stretched but do not deform the boat hull, and the optimal tension angle is approximately 45 degrees relative to the longitudinal axis of the car.
- 🔗 Use separate mounting points for the nose and feed, do not tie them in the same loop.
- 🚫 Do not attach insurance for plastic bumpers or suspension elements that are not intended for traction loads.
- 👀 After the first 10-20 kilometers of the journey, you should stop and check the tension all knots and belts.
⚠️ Warning: Never use rubber bands ("rubbers") as the main or safety element of the attachment - they are prone to sudden rupture and do not provide rigid fixation.
Traffic rules and cargo dimensions
Transportation of bulky cargo, which often include boats, is strictly regulated by traffic rules. According to traffic rules, the cargo should not exceed the dimensions of the vehicle in front and rear by more than 1 meter, and on the sides - more than 0.4 meters.
If your boat is longer than the permitted limits, you must mark the protruding parts, and during the day it is enough to visually control the dimensions, but in the dark or in low visibility (fog, rain) at the ends of the cargo should be installed. light-signature: white in front, red in back.
If the cargo is more than 1 meter in size, the installation of the sign "Bulky cargo" is a mandatory requirement of the law, not a recommendation.
It is also important to consider the height of the vehicle with the load, especially when entering parking lots, gas stations or under bridges. The standard height limit on many roads is 4 meters, but low arches or tree branches can come as a nasty surprise for the high profile of the rooftop boat.
Speed mode during the transport of the boat should be reduced. Even if the traffic allows you to move faster, the aerodynamic drag and sailing of the boat significantly increase the braking distance and reduce the stability of the car on the road, especially in lateral winds.
Control of the way and driving specifications
Driving style when transporting a boat on the roof should be radically different from usual driving. Avoid sudden accelerations, braking and rearrangements, as inertia of the cargo can lead to skidding or even overturning the car.
A particular danger is the side wind, which can play the role of a sail. When leaving protected areas for open spaces (bridges, steppe, open banks of reservoirs), hold the steering wheel firmly and be ready to snatch the car to the side.
Planned stops for inspection of cargo should be made every 50-70 kilometers or after passing of sections with poor road surface.
- 🔍 Tension of the main belts and safety cables.
- 🧵 Integrity of slings and lack of rubbing.
- 📍 The boat is moving relative to its original position.
What to do if the belt bursts on the road?
If you break your belt at high speed, don't make sudden movements, slow down smoothly, turn on the alarm, and find a safe place to stop. Don't try to catch a waving cargo on the go.
Remember that wind-noise The boat can be significant, tiring the driver and reducing concentration, and using fairings or properly aligning the boat (sharp nose forward) helps to minimize this effect.
Frequently Asked Questions (FAQ)
Can I transport a motorized boat on a transom?
It's not recommended. The motor puts extra stress on the transom, which, when vibrating, can cause it to collapse, and the carburetor and fuel system must be in a certain position, which is difficult to ensure when transporting on the roof, and the motor is better removed and transported in the cabin or trunk.
Do I need to completely lower the PVC boat before shipping?
It is not necessary to lower the boat completely, but it is recommended to reduce the pressure in the cylinders to 0.2-0.25 atm if the ambient temperature is expected to rise, this compensates for the expansion of air inside the cylinders and prevents the joints from rupturing. However, for short trips in cool weather, you can leave the working pressure.
What is the maximum speed to be followed?
Although traffic can allow higher speeds, experts recommend not to exceed the mark of 90 km / h At speeds above 100 km / h, the aerodynamic lift becomes critical, and the fuel consumption of the car increases significantly due to increased air resistance.
Is it dangerous to transport a boat in rain or snow?
Moisture itself is not a big deal for modern materials, but wet boats get heavier and slip coefficients change, and the main thing is that after a trip to the precipitation, be sure to dry the boat before packing in a case to avoid mold and unpleasant smell.
