The owners of the boats know that the main wear of the boat does not occur during operation on the water, but during storage on the shore. Aggressive ultraviet radiation, temperature changes and precipitation can destroy in one season. plasticizer It's a PVC material that makes it fragile and brittle, and that's why professionally tailoring boat covers is not just an accessory, but a vital investment in the durability of your property.
A well-made awning creates a reliable barrier, keeping the cylinders elastic and preventing the cockpit interior from fading, but simply buying a finished case is often not enough, as the factory size may not take into account the individual features of the specific model or equipment installed.
Individual tailoring allows you to take into account every detail: from the height of the transom to the location of the leer racks. The accuracy of cutting, taking into account technological tolerances for seams and ventilation gaps, is a critical factor determining the service life of the protective coating. In this article, we will discuss in detail all the steps to create reliable protection for your boat.
Criteria for the selection of textile material for aquatic environment
The first and most important step in the process of creating a protective coating is the choice of a protective coating. base-stuffThe market offers many options, but not all of them are suitable for harsh open-air applications, with the main contenders being polyester-based fabrics with polyurethane or polyvinyl chloride coatings, as well as acrylic fabrics.
PU-coated polyester fabrics are highly tensile and water-resistant, lightweight, fast-drying and tensile, making them ideal for running awnings. However, for stationary shelters that will last for months, it is better to consider denser options with increased protection from the air. UV radiation.
- 🧵 Oxford (Oxford) - durable fabric with interlacing threads, often having a polyurethane coating, perfectly holds the shape.
- ☔ Tarpaulin (Tarpaulin) reinforced polyethylene, which has absolute water resistance, but less aesthetic.
- 🌞 Acrylic tissues (Sunbrella) A premium segment that provides better ventilation and color protection, but requires an impregnation.
When choosing a material, you need to pay attention not only to the density measured in grams per square meter, but also to the indicator of the value of the material. UV stabilityCheap analogues can lose their properties after one season of active sun, starting to crumble on the folds.
Technology of cutting and creating templates
The process of sewing a case on a boat begins long before the sewing machine is used, and accuracy is the key word in this phase, and a few centimeters of uncut error can cause the finished product to either be pulled like a drum, risking breaking in the wind, or dangling around collecting rainwater.
There are two main methods of creating patterns: mathematical calculation and taking measurements directly from the boat. The first method is suitable for experienced designers who know the geometry of a particular type of vessel. The second method is more time-consuming, but guarantees a perfect fit. This uses soft roulette and, in difficult cases, creating a layout from inexpensive technical fabric.
When taking measures, it is important to consider technological We need to put in the seams, which can be from 1 to 3 centimeters depending on the type of connection, we also need to lay the tolerances for flexing the edges and installing fasteners, and we also need to remember the wind reserve, if the case does not have a rigid frame.
Special attention should be paid to areas of high load: corners, attachments to the leers and the transom, where the fabric experiences maximum tension. Reinforcing inserts Or a double layer of material in these places will significantly extend the life of your case.
Selection of threads and type of sewing joints
Even the strongest fabric will not last long if the seams are poorly made. reinforced threadUV-resistant and rotting: Ordinary cotton or cheap synthetic threads will rot or break down under the sun in one season, leaving the fabric without compounds.
The best choice is considered to be 100% polyester threads with markings. ll They're very tensile, they don't absorb moisture, and the thickness of the thread is determined by the density of the tissue, 40-60 for light awnings, 10-20 for heavy shelters.
The type of seam is also critical, because a simple sewing seam can pass water through the needle punctures, so the standard for water is that the seam is a water-based seam. double-lined with subsequent gluing of suture tape or the use of special sealing compounds.
☑️ Checking tailoring readiness
The step of the line should be optimal: too rare seam will not ensure tightness, and too frequent will turn the line of connection into a sieve, weakening the fabric.
Mounting and wind protection systems
The boat case is constantly exposed to wind, and if it is not securely secured, wind loads can tear the fabric or, worse, damage the vessel itself, and the mounting system must be overly strong and allow for adjustment of tension.
The most common attachment is the luvers, which are metal rings that are inserted into the fabric and rolled out by a press, which prevents the tissue from breaking through the cords or belts.
| Type of attachment | Materials | Application | Reliability |
|---|---|---|---|
| Luvers | Brass/Stainless steel | Main perimeter | High. |
| Textile belts | Polypropylene | Fixation to the leers | Medium |
| Velcro straps (Velcro) | nylon | Temporary fixation | Low. |
| Reducer rubbers | Rubber/Tissue | Wind compensation | High. |
| Luvers | Brass/Stainless steel | Main perimeter | High. |
| Textile belts | Polypropylene | Fixation to the leers | Medium |
| Velcro straps (Velcro) | nylon | Temporary fixation | Low. |
| Reducer rubbers | Rubber/Tissue | Wind compensation | High. |
The distance between the loovers is usually 30-50 cm, but in windy regions it is recommended to reduce it to 20-25 cm. stainless-steel or brass, as the ordinary metal will rust and leave a stream on the fabric.
⚠️ Note: When installing luvers, be sure to use sealing washers on the back of the fabric so that the sharp edges of the metal do not cut the fibers when stretched.
Additionally, you can use the system of internal pockets for installing spacer racks that will not allow the awning to sag and accumulate water during rain.
Condensation protection and ventilation
One of the main problems with sealed covers is condensation, and the difference in temperature during the day and at night causes moisture from the air to settle on the inside of the tent and on the parts of the boat, which can cause mold on the seats and corrosion of metal elements.
To solve this problem, a system must be provided. forced or natural ventilationIn the simplest models, these can be vents, closed with insect mesh, located in the lower part of the side and in the upper part of the awning (thrust effect).
A more advanced solution is to install deflectors that drive winds to pump air under the cover, and there are special ventilation valves that only open when a certain pressure is exceeded inside.
Lack of ventilation is a direct route to damage the boat, and in a confined, humid environment, the decay and corrosion are accelerated at a rate of several times.
When sewing, it is important not to make ventilation holes in places where rainwater can flow in oblique rainfall, the optimal location is under overhangs or in vertical planes.
Textile care and storage
Even the best quality case requires proper care: dirt, dust and bird droppings contain substances that can destroy the protective layer of fabric and thread. Regular cleaning extends the life of the product by one and a half to two times.
For cleaning a soft brush and warm water using special means for synthetic fabrics. Aggressive solventschlorine-containing substances and hard brushes are strictly prohibited, as they damage the polyurethane coating.
Keep the case in a dry, ventilated place, rolled up. It is not recommended to keep it in a compressed state for a long time, it is better to fold it in large free loops. Periodically, once a season, it is useful to treat the fabric with water-repellent impregnation (DWR), restoring its protective properties.
Timely minor repairs, such as sealing punctures or replacing the luver, will prevent the damage from spreading. Ignoring minor defects can cause a gust of wind to tear the fabric along the entire length of the seam.
Cost of manufacture and economic feasibility
Many boat owners are asking themselves, is it worth ordering custom tailoring, or is it possible to do with a universal solution? Universal covers are cheaper, but they rarely sit perfectly. The gaps lead to sailing, and tight fitting in unnecessary places leads to wiping.
The cost of tailoring is based on the cost of the material, the complexity of cutting and the amount of manual work, but if you consider this as an investment, protecting a boat worth several thousand dollars from destruction by ultraviolet light for 300-500 dollars seems quite reasonable.
And then you also get a product that's completely tailored to your needs, with pockets for fun, motor reinforcement, or special valves, a level of comfort and safety that you can't achieve with off-the-shelf solutions.
Frequently Asked Questions (FAQ)
How often should I change my boat cover?
The life of a quality case is from 5 to 10 years depending on the operating conditions and the region. In southern latitudes with high solar activity, the resource may be less - about 3-5 years.
Can I wash my clothes in the washing machine?
Most modern fabrics for boat awnings are not designed for machine washing, especially with pressing. Mechanical impact of the drum can damage the protective coating and tightness of the seams. manual brushing and hose rinsing are recommended.
Should I put the lightning on my cover?
Yes, lightning, especially if it comes in contact with salt water or dust, requires maintenance. Use silicone zipper lubricant. Don't use oils or fats, as they attract dirt and can stain the fabric.
Will the cover protect the boat from hail?
A standard fabric tent of 200-300 g/m2 will protect against fine hail and branches, but large hail can damage both the case and the boat below it.
Which color of cover is better to choose?
Light colors (gray, beige, white) reflect the sun's rays better, preventing the interior of the boat from overheating; dark colors (blue, green, black) heat up more, but they are less noticeable dirt; the choice depends on priorities: keeping the temperature inside or aesthetics.
