Transporting a boat over long distances always involves risks associated with vibration, wind gusts and irregularities, which is why the correct fixation of the hull is not just a formality, but a critical stage in preparing for the departure to the reservoir. tie-belt They can cause displacement of the boat, damage to the side or even an emergency situation on the highway.
The modern market offers a wide range of solutions, from simple rubber harnesses to complex systems with ratchets. Owners of both lightweight inflatable models and heavy aluminum boats need to understand the difference between the two. transport-belt And then we have the screeds that are used to hold the body directly against the pad, and mistakes in the type of attachment that are made often cause the belt material to be rubbed against the edges, and the tension to be weakened after a few kilometers.
In this article, we will discuss in detail the design features of fasteners, their material execution and methods of safe installation. static tension of the belt shall not exceed 70% of the breaking loadAnd how to set up a locking system that will withstand any road test, and a sound approach to this issue will prolong the life of both the boat and the trailer.
Types of tie belts and their design features
The basis of any fastening system is the belt itself, which is most often made of polyester tape. This material is not chosen by chance: it has a minimum tensile coefficient, is resistant to ultraviolet light, water and chemical influences. However, in addition to the material, the critical element is the tension mechanism. snoring-belt (ratchets), which allow you to create a powerful pulling force and securely fix the tape in a strained state.
The alternative to ratchets is cam-type tensioners, which are simpler in design, lighter in weight and, importantly, less demanding in care, because they have nothing to jam with sand or dirt. However, they are more difficult to create a force comparable to ratchet, so they are more often used for light inflatable boats or as additional safety ties. For heavy shells, it is preferable to use ratchets that provide rigid fixation.
Special attention should be paid to hooks that are attached to the frame of the trailer. These can be made in the form of grippers with sharp teeth, in the form of rings or have the shape of an "S." Hooks with teeth provide a reliable hook for the profile of the frame, but can damage the paint. Smooth hooks-rings are safer to cover, but require welded eyelets. The choice of the type of hook depends on the design of your car. boat-trailer and personal preferences.
There are also specialised belts with soft loops at the ends that do not scratch the sides, ideal for fixing PVC boats where metal contact with rubber is not allowed, and some models use additional rubber linings on the back of the belt to prevent slipping on the smooth surface of the hull.
⚠️ Warning: Never use unprotected conventional cargo belts to anchor the boat if their hooks may come into contact with the sides. Metal elements act as abrasive when vibrating, instantly damaging PVC or fiberglass.
Manufacturing materials and environmental resistance
The durability of screeds depends on the quality of the materials used, and it's based on polyester tape, which, unlike nylon, absorbs little moisture, and if a nylon belt gets wet, it can stretch to 5 to 7 percent, which will weaken the boat's mounting on the go, and polyester maintains its geometric dimensions even in high humidity, making it the standard for boating applications.
Metal elements — ratchets, hooks and axles — must be protected from corrosion. The best option is to galvanize or use stainless steel. chrome parts look aesthetically pleasing, but when chipped, rust spreads under the coating very quickly. For use in salt water (transport from the sea), it is recommended to choose fittings from the ground floor. stainless steel AISI 316.
The textiles are also specially treated, and quality products are impregnated to repel dirt and water, and this prevents the strands from rotting and mold from being stored in a garage or shed, and cheap products often lack this protection, and after a season of active use, their fabric begins to rag and lose strength.
The important parameter is the temperature mode of operation: polyester tapes retain elasticity at temperatures from -40 to +80 degrees Celsius, which allows you to use screeds all year round without fear that in the cold the material will become brittle and burst when you jerk.
Specifics of fastening of PVC inflatable boats
Fixing inflatable boats has its own unique features, which are related to the softness of the hull. The main task is to distribute the pressure of the screed so that the cylinders do not deform, but also to firmly press the boat against the trailer. Using conventional straps can be dangerous here: when heated in the sun, the air in the cylinders expands, the pressure increases, and the belt can simply cut the side or burst itself.
For PVC, the best solution is to use wide belts (at least 50 mm) in combination with soft linings. protector-belt It's made of felt or thick rubber that is applied under the screed at the point of contact with the balloon, which allows you to increase the area of the press and reduce the point pressure on the material.
The mounting pattern is usually this: the boat is placed on the trailer, the nose is fixed through the transom studs or by the nose handle, and the main fixation of the hull is carried out by transom straps through the keel. It is important not to pull the cylinders. It is enough that the boat does not move when pushed with the hand, but when you press your finger on the board under the belt, you feel elasticity.
- 🔹 Use wide belts (50-75 mm) to distribute the load over the area of the cylinder.
- 🔹 Be sure to apply protective pads made of soft material at points of contact.
- 🔹 Check the tension after the first 10-15 km of the path, as the material may sit down a little.
- 🔹 Do not fasten the belts for the handles for carrying - they are not designed for such loads and can come off.
Special attention should be paid to the fixation of the bow. Inflatable boats often use a belt with a carabiner, which clings to the bolt on the nose, if there is no such element, the belt is passed under the keel in the bow, but necessarily through a protective lining, so as not to damage the bottom when driving.
Fixing of metal and rigid housings
Aluminum and fiberglass boats require more rigid fixation because of their weight and hull hardness. You can already apply a significant force of the ratchet to eliminate any micro-shifts. The main risk for rigid hulls is friction on the lodging and the side of the trailer, so the presence of rubber inserts on the paddles is mandatory.
For boats and heavy boats, it is recommended to use a system of at least four screeds: two in the bow and two in the stern, located cross-cross or perpendicular to the axis of motion, which creates a stable geometry of attachment. Transport belts in this case, work on the press, not on weight retention, since the main load takes on the frame of the trailer.
When fastening fiberglass boats, it is critical to avoid metal hooks from contacting the gelcoat. Any scratch can become a focus of osmosis in the future. It is recommended to use hooks with plastic linings or special hooks that are attached to the components of the trailer structure without touching the side.
When transporting a boat with an installed engine, be sure to fix lower unit with a separate belt, pressing it against the transom board to avoid vibration and breakage of the lower unit leg.
If you use a trailer with keel rollers, make sure that the screeds do not clamped the keel at one point, creating a risk of deformation of the hull. It is better to use wide soft slings covering the keel throughout the width, or attach to the on-board elements, if the design of the boat allows.
Instructions for fitting and tightening belts
The proper installation of screeds is the key to a safe journey, starting with visually inspecting the belts for scuffs, breaks of threads and corrosion of metal, if the belt is defective, it is forbidden to use, then properly position the boat on the trailer, aligning it on the central axis.
The tightening process must be consistent. First, the nose, then the aft, and only then the main transom screeds are installed. The tension is smooth, without jerking. Once the ratchet is snapped, you need to check if the tape is flat, without torsion. The twisted belt loses up to 30% of its strength.
☑️ Boat anchorage checklist
The loose ends of the belts must be assembled and fixed by rubber bands or special holders. The sloshing tape can be quickly caught under the wheels of the trailer or wound onto the suspension elements, which will cause the attachment to break. For long tails, you can use the method of twisting or binding with a knot, which is easy to unwind with one hand.
| Type of boat | Recommended belt width | Type of tensioner | Number of points required |
|---|---|---|---|
| PVC (up to 3.2 m) | 25-35 mm | Fist-fist. | 2-3 |
| PVC (from 3.3 m) | 50 mm | Snoring (small) | 3-4 |
| aluminum | 50 mm | Snoring (medium) | 4 |
| Glass-plastic/boat | 50-75 mm | Snoring (reinforced) | 4-6 |
⚠️ Warning: When tightening your braking belts, never use the extension tubes for the lever. Excessive force can deform the boat hull or damage the trailer frame.
Care, storage and security measures
Strips require minimal but regular maintenance, and after every trip, especially on wet or salty roads, they are recommended to be washed with fresh water and dried, and wet belts should not be kept in a rolled-up state, which will lead to rapid decay of the fabric and corrosion of the metal.
Periodically, you need to lubricate the moving parts of the snoring mechanism with silicone lubricant, which will ensure smooth operation and prevent jamming at the most inopportune moment, and if the mechanism starts to jam, it should be disassembled, cleaned of dirt and old lubricant, and then reassembled.
The life of quality screeds is 3-5 years in active use, however, if the belt has been subjected to critical overload, UV radiation or contact with aggressive chemicals, its life may be reduced. If there are signs of fatigue of the material (fading, glossy coating on the fibers, crunch when flexing), the belt should be replaced.
What to do if the belt bursts on the way?
If the belt bursts on the track, don't try to tie the ends with a knot, the strength will drop by 50%. Use a spare belt or, in extreme cases, temporarily fasten the boat, reducing the speed to 40 km / h and reaching the nearest auto parts store. Safety is more important than time.
Safety on the road depends on small things. Always have a spare set of screeds in the trunk. This is an inexpensive accessory that can save the situation in the event of an unexpected failure of the main mount. Don't skimp on quality by choosing products from proven brands, such as: Securite, Braun Or specialized marine brands.
Regular visual inspection and proper drying after the trip increase the service life of the belts by 2-3 times.
Frequently Asked Questions (FAQ)
Can I use regular cargo belts to fasten the boat?
Technically, you can, if they're long enough and have a good load capacity. But cargo belts often have sharp hooks that can damage the sides, and they don't always have the resistance to water and salt. It's better to use specialized sea screeds.
How often should I change my belts?
The recommended replacement period is every 3-5 years, or if there is visible damage: scuffling, filament breaks, corrosion of the mechanism or deformation of hooks. If the belt has been in a critical situation (sharp jerk, overload), it is better to replace it immediately.
What is dangerous with a strap on a PVC boat?
Excessive tension can lead to deformation of cylinders, disruption of the geometry of the bottom (bubbles) and even tearing the material at the seam. In addition, when heated in the sun, the pressure inside the boat increases, and the overt belt can burst itself or damage the hull.
Do I need to remove the motor during transportation?
For light inflatable boats, the engine is often left behind, securely fixing the lower unit. For heavy boats and long trips on the highway, it is better to remove the engine to reduce the load on the transom and reduce the sailing of the structure.
