The boat itself offers a limitless opportunity to the fisherman or boat driver, but the question of transporting it often becomes a headache. flat-trailer It is considered one of the safest and most gentle ways to transport small craft, especially when it comes to expensive fiberglass hulls. Unlike roller systems, lodgings provide point or linear support, spreading the load along the entire length of the keel, which is critical to preserving the geometry of the boat.
When choosing such a system, owners often face the dilemma of buying a ready-made factory kit or assembling a structure DIY from a profile pipe. Both options are eligible for life, but require careful calculation of the angles of inclination and height of the supports. foot-hold can lead to cracks on the bottom after the first trip along the highway, so the issue of technical equipment should be approached with engineering accuracy.
In this article, we will discuss in detail all the nuances of the operation of such trailers, from the choice of coating materials to the intricacies of adjusting for a particular model of the boat, you will learn why soft supports, rather than metal rollers, are better suited for certain descent conditions, and how to extend the life of your transport equipment.
Advantages of the Loment System before the Roller
The main difference loaf-trailer The rollers only touch the vessel at narrow points, which, when transported or vibrating at high speeds, can cause local overload of the skin material. Logs, especially wide, cover the sides, creating a cocoon effect and preventing any transom shifts of the cargo.
Another big argument for this system is that it's universal. If a roller trailer requires almost perfect alignment of the curvature of the rollers and the keel, then it's a very good idea to have a roller trailer. plug-in This is especially true for boats with complex bottom geometry or flat bottoms, where the fulcrum of the rollers may not match the power frames.
It's also worth noting the shock absorbing properties of quality carpeting. When you drive rough roads, the soft base extinguishes the microstrokes that the hard roller metal broadcasts directly to the hull. For owners of fiberglass boats and composites, this becomes a crucial factor, because repairing the gelcoat is a time-consuming and expensive process.
Design features and types of pawns
The modern market offers many variations of support systems, which are divided by the type of coating and construction of the supporting frame, the main element here is a metal pipe (square or round), which is worn a special cover or coated. Types of pads They range from simple wooden beams upholstered with carpet to high-tech polymer profiles.
The most common supports are covered with a special carpet material, resistant to rotting and ultraviolet light. carpet-passement They provide excellent grip and protection, but require periodic drying after the season, with the alternative being rubber or plastic linings that do not absorb water but can be slippery when loading the boat onto the ramp.
When buying a used trailer, be sure to remove one cover from the pad - under it may hide corrosion of metal, which is not visible from the outside.
The frame design also plays a role, with fixed angle systems and telescopic options that allow you to change the length of the departure. Heavy boats often use double lodgings that distribute the weight over a large area, excluding the underbody pressing at the points of support.
Calculation of the number and layout of supports
The right placement of the supports is the foundation of safety in transportation. lay-pair For light inflatable boats or small PVC models, two pairs of supports may be enough, whereas for a heavy boat longer than 5 meters, a minimum of four or even five support points on each side will be required.
The layout must be strictly consistent with the power set of the body, and the supports should not be placed on flat areas of the skin between the frames, as this will lead to deformation. load It is placed on the keel and bottom stringers, where the boat's structure is the most durable.
- 📏 The front pair of lodgings is usually located in the area of 1/3 of the length of the transom, taking on the main weight of the engine and stern.
- 📏 The central group of supports should support the widest part of the body, providing stability from roll.
- 📏 The nose support (or pair) fixes the forespigel, preventing longitudinal displacement during braking.
As the length of the vessel increases, the number of intermediate supports must be proportionally increased.
The golden rule: the more support points, the less the load on each of them, but the more complex the process of adjusting the entire system.
Coating materials: carpet, rubber or plastic
The choice of material for coating the paddings is always a compromise between the protective properties and ease of use. carpet (often called "trailer carpet") is highly wear-resistant and has excellent traction, and it doesn't scratch the sides even when there's sand that inevitably hits the ramp.
Plastic and rubber analogues, such as pint They're not dry, they don't mold, they're easy to wash with a stream of water, but their main drawback is the low friction ratio, and the boat on these beds can slip off in a sharp maneuver, unless you use additional locks.
⚠️ Attention: Cheap building carpet is categorically not suitable for trailers! it quickly soaks up with water, rots and loses strength in one season, leaving rusty streams on the body.
There are also combinations where the base is made of solid polymer and the top layer is soft-flavored, combining plastic durability and carpet protection, although they cost significantly more than standard ones.
Instructions for self-assembly and adjustment
Building your own trailer or remaking a trailer for a specific boat requires care and a basic set of tools. Before you start, you need to take the dimensions of the bottom of your vessel, identifying the points of greatest curvature. lay-system It is better to carry out, putting the boat on already installed, but not yet fixed finally supports.
To work, you will need broad-cap bolt connections to be able to change the height and angle of each support independently. adjustable It greatly simplifies the process, allowing you to adjust the height under the waterline without the use of complex templates.
☑️ Checking trailer readiness
After installing the boat, check the gaps. There should be no more than 1-2 cm voids between the side and the padlock, but you can not squeeze the hull "to the crunch" either. The adjustment is carried out by trial and error: fixed, rolled on a flat area, checked, removed, examined the traces of contact.
The final step is to check the locking, and the boat should be dead, not staggering from side to side when it hits, and if there's a backlash, you should add side restraints or tighten the belts.
Trailer care and winter storage
Operating in salt water or just in an aggressive environment requires regular maintenance. Metal structures, even galvanized ones, are susceptible to corrosion. Pay special attention to welding sites and attachments. bed-stackwhere the most common rust begins.
Carpet coating requires drying after each outing, and if you leave wet beds for the winter, ice forms inside, which, when expanded, can damage the fabric structure or the metal of the base. Seasonal storage involves removing covers, cleaning and drying them in a warm room.
| Element of the system | Frequency of verification | Type of service |
|---|---|---|
| Carpet coating | After each trip | Drying, sand cleaning |
| Fastening bolts | Before every season | Ply, thread lubrication |
| Metal frame | Once a year. | Scrap inspection, painting |
| Adjustment units | When changing boats | Lubrication of moving parts |
How to restore a damaged carpet?
If the carpet on the pawns has broken or rotted, it can be replaced yourself. To do this, remove the old material, clean the pipe from rust, cut a new piece of special carpeting in size and tightly tighten, fixing the clamps or stitching the edges with a strong thread.
Comparative table: Logements vs. Rollers
To make a final decision, you need to put all the arguments in a single table, which will help you visually assess the pros and cons of each type of support for your specific use case.
Roller systems benefit in the speed and ease of self-loading, as the boat literally rolls over them. lodging-trailers They win in safety and versatility, which is a priority for many owners.
| Characterization | Log trailer | Roller trailer |
|---|---|---|
| Protection of the hull | High (distributed load) | Medium (point load) |
| Self-boot | Difficult (needs winch) | Light (manual rolling) |
| Universality | High (Angle adjustment) | Low (under a specific keel) |
| Service | Carpet drying, fastening checks | Roller bearing lubrication |
Frequently Asked Questions (FAQ)
Can you use regular wooden bars instead of special beds?
Technically possible, but not recommended for permanent use, the tree quickly absorbs water, swells, rots and can start to lithe under load, coloring the hull. Also, the geometry of the bar does not always repeat the contours of the boat. This is permissible as a temporary solution, but for safety it is better to use specialized carpet-passement.
How often should you change the carpet on the floor?
The service life of the coating is 3-5 seasons with active use. If you notice that the carpet has become rigid, the pile has worn to the base or there are signs of rotting, you need to replace it immediately so as not to damage the gelcoat boat.
Will the trailer withstand the carriage of a boat with a hard keel?
For boats with sharp or hard keel (for example, some models of aluminum or fiberglass), you need to use narrow, high lozenges or special keel rollers in the front so as not to push the skin at one point.
Do I need to take the boat off the bed for the winter?
Yes, it is a mandatory procedure, and staying on the same footing points for a long time can cause the hull to deform under its own weight, especially in a warm room, and it will also allow for the audit of the beds themselves.
