As the navigation season begins, every owner of a boat faces the question of safe and fast delivery of water transport to the launching site. boatIt's also a road emergency where the cost of error is too high, which is why the right boat belts are not just an accessory, but a critical piece of equipment that requires careful consideration when choosing.
Many beginners mistakenly believe that it is enough to just wrap a rope or use the first sling, but the dynamics of movement at high speeds dictates its own harsh conditions. Vibration, wind gusts and inertia during braking create a huge load on the mounting points, which can withstand only specialized equipment. riggingIn this article, we will discuss in detail the types of fasteners, technologies for their application and typical errors that owners make. PVC and metal boats.
High-quality fixation ensures the safety of the geometry of the body and prevents the displacement of the load, which is especially important for long-dimensional objects. tie-belt They allow the pressure to be evenly distributed across the sides, eliminating the risk of warping or tearing material during abrupt maneuvers, so let's look at how to turn the loading process into a smooth, time-consuming procedure.
Classification and types of belts for water transport
The rigging market offers many options, and the choice of the specific type depends on the material of the boat hull and the design of the trailer. The main separation is by the type of material used and the presence of a tension mechanism, which directly affects the reliability of the cargo locking in transit. For light inflatable boats, simpler options are often used, whereas heavy aluminum boats require reinforced systems with a high load. snoring-mechanism.
Fabric slings without metal elements, often called soft ones, are ideal for fixing inflatable tubes. PVC They don't scratch material, they don't fear water, they don't fear water over time, they also have a high elasticity to compensate for vibration, but their load-bearing capacity is limited, and it's not recommended to use them to rigidly fix heavy metal at high speeds.
For heavy loads, combined belts with metal carbines and tension devices that provide controlled screed force are used, which allow for the necessary pretension, eliminating sagging and chattering of the boat while driving along the highway. It is important to understand the difference between simply holding slings and power elements that take on the main inertial load.
- 🪢 Tissue bindings: simple loops of durable tape used for temporary fixation or light boats.
- 🔒 Ratchet straps (Ratchet straps): equipped with a rattle to create high tension, ideal for metal housings.
- 🤏 Clamp tensioners: compact devices that allow you to quickly tighten the sling without the use of complex mechanisms.
- 🔗 Chain screeds: They are rarely used, only for super-heavy boats, require special linings to protect the board.
⚠️ Attention: Never use belts with damaged braiding or deformed metal fittings. Even a microscopic tear on a sling under load can instantly turn into a complete tear, resulting in the loss of a boat on the move.
When choosing between different types, you should focus not only on the price, but also on the declared burst load, which should always have a margin. For amateur use, the optimal solution is universal models with plastic or metal buckles that provide a balance between convenience and reliability. belting It is an investment in the safety of your cargo and other road users.
Manufacturing materials and their impact on durability
The basis of any high-quality belt is polyester tape, which is characterized by high tensile strength and minimal tensile coefficient. polyester It retains its geometrical parameters even after prolonged contact with water, which is critical for water-related applications where equipment is constantly exposed to aggressive environments.
Metal elements such as hooks, carbines and ratchets must be made of hardened steel with anti-corrosion coating. Galvanic galvanic galvanic galvanic or oxidation protects the mechanism from rust, which inevitably occurs when in contact with salt water or just moist air. Cheap silumin or soft metal analogues quickly deform and can burst at the most inopportune moment under the influence of the action of the drug. inertia.
Special attention should be paid to the seams and joints of the tape with metal parts, as this is where the most often occurs destruction. Quality products undergo double or triple threading with reinforced thread, which guarantees the integrity of the structure under jerking loads. Cheap belts often have adhesive joint or single seam, which is a direct threat to safety during transportation.
Why is polyester better than nylon for a boat?
Nylon loses up to 10% of its strength when wet and is severely stretched, which can lead to weakening of the boat's mounting in transit, Polyester practically does not absorb water and keeps the shape, ensuring stable fixation of the cargo regardless of weather conditions.
The durability of rigging depends on its maintenance, even if the materials are declared to be resistant to ultraviolet radiation and chemistry. After each trip, especially on sea water, it is recommended to wash the belts with fresh water and dry in a straightened form to avoid mold formation and rotting of threads in the depth of the weave. sling Faith and truth are served for many seasons.
Features of fastening boats from PVC and aluminum
The technology of fixing inflatable boats is radically different from fastening rigid hulls, requiring a more delicate approach to pressure distribution. PVC Metal hooks that can damage cylinders or wipe them when vibrating are strictly forbidden from using materials, instead, wide soft slings covering the sides and bottom are used, often in combination with protective corners or linings.
Aluminum and fiberglass boats allow for the use of rigid overboard grips or special lodgings on the trailer, where the hooks of the belts are inserted. The main task here is to prevent the hull from shifting relative to the trailer, so the tension should be maximum, but without fanaticism, so as not to deform the hull. balk Often, a circuit is used where the nose and feed are fixed separately, and the center is pressed with cross screeds.
An important aspect is the protection of the points of contact where the belt rubs against the side, because during long transport even soft tape can damage the paintwork. The use of special linings of felt or rubber in the contact of metal and the boat hull prolongs the life of the boat. The correct mounting scheme takes into account the center of gravity and aerodynamics, preventing the sailing effect.
To protect the PVC side of the boat, put a piece of dense foam or a special soft lining under the belt - this will prevent the appearance of scuffs on the material during prolonged shaking.
When carrying inflatable boats assembled, it is recommended to apply pressure in the cylinders slightly in front of the road to compensate for the change in air volume under changes in temperature and pressure, this will reduce the internal stress in the materials and reduce the load on the gluing sites, which may not withstand the combination of internal pressure and external compression with the belts. tightness and the integrity of the seams.
The correct scheme of installation and stretching of belts
The process of fixing the boat on the trailer must be performed in a certain sequence to ensure an even distribution of forces. First, the boat is mounted on supports or pads, after which the bow part is fixed, which takes the main load when braking. Only after a reliable fixation of the nose can the stern and lateral mounts be started. screedControlling the symmetry of the position.
The straps must be pulled incrementally and alternately, pulling one slightly, moving to the other, then coming back and adding force, and this avoids skewing the boat, and ensures that all the anchor points work together to create a single rigid structure. The use of ratchets allows you to create a force that is not available when you tighten the knots manually, which is especially important for heavy lifts. boats.
☑️ Checking of the attachment reliability
It is critical to keep track of the tension angle: the belt must go from the mounting point on the boat to the point on the trailer at an angle close to 90 degrees, or be directed downward. Horizontal or ascending force vectors can cause the boat to just throw up when hit by roughness, which is fraught with slipping from the supports. tension-geometry - the guarantee of a safe trip.
After tightening all the belts, be sure to check the reliability of fixing the carbines and locks, making sure that they do not have free running. The tails of the belts should be carefully assembled and secured with rubber bands or special locks so that they do not flutter in the wind and whip around the body of the car. The final step should always be a check of all the knots after the first 10-20 kilometers of the path, as a new rigging can be a little bit. stretch out.
| Type of boat | Type of belt | Mounting point | Tension. |
|---|---|---|---|
| PVC (inflatable) | Soft sling | For the pens/Day | Average |
| aluminum | With a ratchet. | Overboard/Ducks | Strong. |
| Fiberglass | With a ratchet. | Behind the bolts. | Strong. |
| catamaran | Combined | For cylinders/Rama | Moderate. |
Common mistakes in transportation and their consequences
One of the most common mistakes is to use short-length or heavy-duty belts, which puts the material at the limit of its ability, and in such a situation, any sudden jerk or vibration becomes fatal because the safety margin is completely absent. Owners often save on rigging, not realizing that the cost of belts is incomparable with the price of a lost boat or damaged boat. motor-car.
The wrong location of the anchoring points, when the belt passes through the sharp corners of the transom or brackets without protection, leads to rapid rubbing of the tape. The vibration acts like a saw, and for several hundred kilometers the integrity of the sling can be disturbed, which will become noticeable only when the load is completely lost. protector or to lay the belt so as to exclude contact with sharp edges.
⚠️ Attention: It is strictly forbidden to fasten the belts to the inflatable parts of the boat, unless they are designed for this structurally, or to plastic elements that are not power, this is guaranteed to cause a tear of the cylinder or a detachment of the mounting.
Ignoring tension control in transit is another serious mistake, especially when using new belts or after a long stay. The material can shrink or, conversely, stretch, changing the geometry of the attachment and creating a dangerous backlash. Regular check of the condition of the cargo every 100-150 kilometers of movement is a mandatory rule. safety, which cannot be ignored.
Rigging care and storage in the off-season
Even the best-quality belts require proper care, especially after use in salty water or dirty bodies of water. Salt, sand and silt, getting into the structure of the weave and the mechanism of the ratchet, act as an abrasive, accelerating the wear of rubbing parts. After each trip, it is recommended to rinse the equipment with fresh water and thoroughly dry before packaging to avoid the appearance of rubbing parts. corrosion and mold.
The belts should be stored in a dry, cool place, protected from direct sunlight, since ultraviolet radiation destroys polymer fibers of polyester. It is better to fold them with free rings, avoiding cracks and bends at an acute angle, which can damage the internal structure of the tape. WD-40 To maintain the mobility of the mechanisms.
Before the start of the new season, you need to conduct a thorough audit of the entire rigging, checking the integrity of the seams, the absence of scuffs and corrosion on the metal. If you notice that the tape has begun to flicker, faded or become rigid, it is better to replace such a belt without waiting for it to break under load. The service life of quality equipment with proper care is 5-7 years, after which it is recommended to complete the entire belt. replacement kit.
Timely replacement of worn belts is hundreds of times cheaper than the restoration of the boat or the payment of damage in an accident caused by lost cargo.
How often do I need to change my seat belts to carry a boat?
Life depends on the intensity of operation and storage conditions. On average, quality belts last 5-7 years. However, if you notice scuffing, breaking threads, corrosion of metal or difficulty in working the mechanism, you need to replace immediately, regardless of the age of the product.
Can I use a car seat belt for a boat?
No, it is strictly forbidden. Car seat belts are of a different design, smaller width and are not designed for external dynamic loading and fastening of cargo, their use will not provide the necessary reliability and may be considered by inspectors as a violation of transportation rules.
Do I need to lower the PVC boat before transportation?
It is not necessary to lower the boat completely, but it is recommended to reduce the pressure in the cylinders by 10-15% of the worker, especially in hot weather, this compensates for the expansion of air when heated and reduces the load on the seams and material when compressed with belts.
What is dangerous nylon belt for transportation?
Nylon absorbs moisture (up to 10% of its weight), which reduces its strength and leads to rotting, and it also has a high elongation under load (up to 6-8%), which can cause the boat to "walk" on the trailer, creating dangerous dynamics.
How to properly store belts in winter?
The belts should be washed, dried, folded in vacant coves and put in a dry cupboard or box, it is important to exclude contact with chemicals, rodents and direct sunlight. Metal parts can be slightly lubricated with anti-corrosion compounds.
