The safety of a small vessel on public roads depends on the quality of the rigging used. Many owners, especially newcomers to water tourism, underestimate the forces of inertia that arise from abrupt braking or hitting bumps. wicker-belt It takes on a tremendous load by holding the heavy hull of the boat on the frame of the trailer, and an error in the selection or installation can lead to the fall of the boat on the track, with serious consequences for all participants in the movement.
The main function of this element is to rigidly fix the hull in a given position, preventing displacement and vibration. Unlike slings, which simply cover the load, screed mechanisms (often called ratch belts) allow you to create the necessary tension by pressing the boat against the pad. fittings And the tape material ensures that even after hundreds of kilometers of track, the fasteners will not weaken spontaneously.
In this article, we will take a look at the technical details that will help you choose a reliable tooling, you will learn about the differences in materials, types of locks and proper tying schemes that are approved by experienced water engines. Remember that saving on rigging is the risk of losing an expensive boat.
Criteria for choosing a reliable rigging
The first thing to look at when buying is burst-load For lightweight PVC inflatable boats up to 3.5 meters long, belts with loads up to 500 kg are often enough, but for heavy aluminum or (plastic) boats this figure should be much higher. Always take a margin of safety: if the boat weight is 300 kg, the belt should withstand a minimum of 600-800 kg statically, given the dynamic jerks.
The tape material is also critical. Standard polyester is preferred over nylon, as it is almost non-stretchable under load and does not absorb moisture. Nylon tape can stretch up to 5-7%, which when transporting a boat over long distances will lead to relaxation of tension and the appearance of a dangerous hull boltan on the frame. polyester resistant to ultraviolet and fuel, which is important when operating near motor fuel.
Pay attention to the width of the tape. Too narrow belts (25 mm) can cut the side of an inflatable boat under heavy tension or crash into the plastic hull of a boat. The optimal width for universal use is 50 mm. It provides better pressure distribution and is usually equipped with more powerful metal locks.
⚠️ Attention: Never use plastic lock belts to hold heavy boats. Under sub-zero temperatures or a heavy impact, plastic can burst, causing the cargo to collapse instantly.
When choosing a kit, make sure that the length of the belt matches the dimensions of your trailer. Too long belt will have to be twisted or tied, creating unnecessary knots that reduce strength.
The design of the locking mechanism: a rattle or a ratchet?
The heart of any strap is a locking mechanism. The two most common types of fastening boats are the ratchet and the strap-on tension mechanism. The ratchet allows you to develop a tremendous amount of tension by gradually choosing the length of the tape, and it's ideal for rigid hulls that need to be pinned to the pads.
But with PVC inflatable boats, you have to be careful, because the ratchet force can deform the cylinders or damage the transom. tension-lever It's important that the mechanism be made of galvanized or stainless steel to resist corrosion after contact with salt water.
A quality lock should have a handy gripper even with wet gloves. The mechanism should be fixed in a closed position so that protruding parts do not dangle and hit the side of the boat while moving. Cheap Chinese counterparts often sin with a backlash of the axle, which leads to the gradual self-expanding of the rattle.
Why do locks rust?
Cheap locks are coated with a thin layer of zinc by electroplating. The first scratch or contact with salt water causes corrosion. Choose hot-dip galvanized or stainless steel AISI 304/316.
Fixing schemes: transom and onboard fixation
There are several proven ways to stow belts, and the choice depends on the type of boat and the design of the trailer. The most popular transom scheme is where the belt is thrown over a transom and attached to the front of the trailer or to the winch, which prevents the boat from slipping back when braking.
For complete safety, a cross-schema or fixation is used through special rim bolts on the sides, in which case the belts wrap around the boat hull (through protective pads) and are attached to the side pipes of the trailer, which eliminates cross-shifting and swinginging of the vessel.
☑️ Checking of the anchorage scheme
When you use the onboard circuitry, it's important not to overpower the cylinders. protector Or just pieces of dense tissue that are put under the tape, and they distribute pressure and prevent the body material from abrading against the rough surface of the belt.
The boat should be kept nose-to-stop through the winch, but an additional safety belt on top (from the transom to the trailer's nose) will never hurt, especially when transported on bad roads.
Table of belt setting
To make the selection process easier, use the following matching table to help determine the length and load required depending on the type of vessel you are on.
| Type of boat | Recommended length (m) | Min. burst load (kg) | Type of castle |
|---|---|---|---|
| Inflatable PVC (up to 3.2 m) | 4 - 6 | 400 - 500 | Fist/Cracking |
| Inflatable PVC (3.5 - 4.5 m) | 6 - 8 | 800 - 1000 | A rattle (with caution) |
| Aluminum/Plastic glass | 6 - 9 | 1500 - 2500 | A powerful rattle. |
| Boats and catamarans | 9 - 12 | 3000+ | Industrial clack-up |
The length of the belt is indicated by the length of the mechanism itself and the free end. Always take a belt with a margin of 1-1.5 meters to be able to maneuver when tying knots or attaching to non-standard points.
Rules of operation and care of rigging
Even the most expensive belt will not last long unless you follow the rules of operation. After each trip, especially on the sea or salt lakes, the mechanism must be washed with fresh water. The salt, getting into the moving parts of the rattle, crystallizes and jams the mechanism, making it impossible to use.
Keep your belts dry, ventilated, don't leave them in compressed condition for the whole season, which causes cloth cloth to break and lose elasticity, and it's best to keep them straightened or loosely rolled into rings.
⚠️ Attention: If the belt shows traces of mold, rot or cuts affecting more than 10% of the width of the sling, the belt should be immediately disposed of.
Regularly lubricate the mechanism axis with silicone lubrication, but avoid getting oil on the fabric tape itself, as this can reduce its strength specifications and collect dirt.
Common errors in attachment
One of the most common mistakes is to attach the belt to the keys or plastic parts. The switches are not designed for horizontal loads on the break and can be pulled out of the nest along with a piece of the board. Plastic in the cold becomes brittle and bursts at the first jerk.
It's also a mistake to use knots to lengthen the belt, so any knot reduces the strength of the sling by 40-50%, if the length is not enough, it's better to buy a new belt of the right size than risk the integrity of the load, use only regular length or special extension cords with carabiners.
Remember to check the tension after the first 10-20 km of travel, the tape may stretch a little or "sit down", and the lock will turn.
Use bright orange or red belts, and if you forget to remove them before launching the boat, they will be easier to spot and avoid being pulled off by a trailer without a boat or dragging the trailer into the water.
FAQ: Frequently asked questions
Can I use car seat belts to fasten the boat?
Not recommended: Car belts have different tensile dynamics, are designed to be a one-off jerk in an accident, and have no tension mechanisms, they will not provide the required rigid fixation and can stretch during transportation.
What is the minimum length of a belt for a boat 3 meters long?
For a boat 3 meters long, the optimal length of the belt is 4-5 meters, which will allow you to throw it over the hull, pass through the frame of the trailer and securely lock the mechanism. Short 2-meter belts are only suitable for fixing small objects inside the boat.
What is the difference between WLL and BS belts?
WLL (Working Load Limit) is a workload, that is, a safe weight that can be attached. BS (Breaking Strength) is tensile strength. Usually BS is 2-3 times higher than WLL. When choosing, focus on WLL to have a margin of safety.
Do I have to take off my seat belts in the parking lot?
If the boat is on the trailer in the open air for a long time, it is better to loosen or remove the belts, constant tension deforms the PVC sides and puts an extra load on the frame of the trailer, and the belts can fade from the sun.
Safe transportation of the boat is possible only with the use of specialized rod belts with metal locks, selected with a two-fold margin of safety relative to the weight of the vessel.
