The water element spares neither technology nor people, especially when the sun is at its zenith or suddenly begins to rain. boat-tender It is becoming a critical element of equipment that turns a conventional swimming tool into a full-fledged comfortable boat. Without a canopy, a long stay in open water is fraught with heat strokes for the crew and rapid burnout or cracking of the plastic of the boat itself, especially if we are talking about expensive models of PVC. A quality awning allows you to travel long distances without burning under ultraviolet light, and keeps dry personal belongings even with heavy chop.
Many boat owners mistakenly believe that the awning is just a piece of fabric on the arcs, however, the modern industry offers sophisticated engineering solutions. Driving models They differ significantly from parking or transport counterparts in their aerodynamics, strength of mounts and ability to withstand wind loads at high speeds. A properly selected accessory not only protects against precipitation, but also affects the handling of the vessel, reducing sailing in lateral wind. In this article, we will discuss in detail how to choose the perfect protection, what materials exist and how to avoid typical errors during installation.
It is also worth noting that the presence of an awning significantly increases the liquidity of the boat during resale. lip-slipAs it saves them from having to find the right arcs and fabric, adjust the dimensions and waste time sewing, investing in a quality awning pays off with the comfort of fishing and the safety of property, making every trip through the water a pleasant event rather than fighting the elements.
Design features and types of frames
The basis of any running awning is its frame, which takes over the entire wind load. The most common and reliable solution is stainless steel or anodized aluminum arcs. Steel frames are heavier, but they have high strength and rigidity, which is critical for boats longer than 4 meters. Aluminum alloys, such as: D16TThey are lighter and not susceptible to corrosion, however, they require a thicker profile to achieve the same rigidity, which can increase the sailing of the structure.
The second important element is the way that arcs are attached to cylinders or transoms, and there are systems that focus on special pockets on the sides, and there are also options that are fixed on transom plates. transom anchorages They're considered more versatile because they don't depend on the shape of the cylinders, and they allow you to adjust the height and angle of the awning, but they put extra pressure on the stern, which you need to consider when you install powerful motors.
⚠️ Attention: When installing the frame, make sure that the support points do not have sharp edges. Any barb on the metal with constant vibration on the wave will wipe the boat cylinder in a matter of hours, which will lead to depressurization and expensive repairs.
Special attention should be paid to folding structures that allow you to quickly remove the awning without removing it completely. top Complex hinge joints require regular lubrication and backlash checks, as loosening the knots can cause failure at the most inopportune time.
Tent fabric materials: Oxford, Tarpaulin or PVC
The choice of material is a balance between weight, water resistance and durability. Oxford The density of the fabric is measured in den (den) or g/m2. For chassis tents, the density is considered optimal from 450 to 600 g/m2. Less dense materials can not withstand water pressure in rainstorms or wind gusts, and too heavy will create an excessive load on the frame.
Fabric Tarpaulin Tarpaulin is a reinforced plastic film, a budget option that is completely waterproof but has significant drawbacks. Tarpaulin bluffs and can crack in the cold, and in the sun it quickly fades and loses elasticity. For seasonal use in mild climates, it is suitable, but for serious tourism or frequent use it is better to choose more technological solutions.
Modern materials often have additional impregnations. Silver Star Or similar reflective layers on the inside of the awning allow up to 80% of the sun's radiation to be reflected, which creates the thermos effect under the awning in reverse, keeping a pleasant coolness even in a hot afternoon, and also important is resistance to ultraviolet (UV) radiation, without which the fabric will begin to break down in 1-2 seasons of active use.
When buying fabric, pay attention not only to density, but also to the quality of the seams. Double stitching with a special tape ensures that water will not seep through needle punctures even in heavy oblique rain.
Comparative table of material specifications
To make it easier to choose, consider the basic parameters of popular materials in numbers, which will help you understand what you pay for and where you can save without losing critical properties.
| Parameter | Oxford 450 PU | Oxford 600 PVC | Tarpaulin (Reinforced) | Acrylic cloth |
|---|---|---|---|---|
| Weight (g/m2) | ~450 | ~600 | ~350-500 | ~300-400 |
| Water resistance | High. | Very high. | Absolute. | Medium (requires impregnation) |
| Resistance to UV | Good. | Great. | Medium | Excellent. |
| Temperature conditions | -40...+60°C | -50...+70°C | -30...+50°C | -20...+50°C |
| Term of service | 5-7 years | 7-10 years | 2-3 years | 5-8 years |
The table shows that Oxford with PVC coating It's a middle ground for running awnings, and it combines strength, flexibility at low temperatures and excellent water resistance, and acrylic fabrics, which are popular in the automotive industry, are worse off on the water because of their hygroscopic nature, which can absorb moisture and become heavier, and also moldy when stored in a wet state.
Aerodynamics and influence on driving performance
The awning changes the aerodynamic profile of the boat, and the tall flat-roofed awning works like a sail, which is especially noticeable in lateral winds, and can cause the boat to be demolished off course and increase fuel consumption, because the engine has to compensate for the drag, so modern running awnings are made with a rounded or wedge shape, so that air flow around the structure rather than being braked against it.
An important aspect is that there are transparent windows, which not only provide a view, but also allow the space to be ventilated under the awning, preventing fogging. polyvinyl chloride (PVC) Or polycarbonate must be properly sewn, a poorly strained window will slam in the wind, making an annoying noise and quickly wear out in the attachment areas, and some models include the ability to remove window valves for better ventilation in hot weather.
⚠️ Warning: Do not attempt to reach the top speed of a boat with a fully closed awning ("tightly"). The air accumulating inside can create excess pressure that will twist arcs or tear off the mounts. Always leave the vents or open the rear valve.
Also worth considering is the effect of the awning on the center of gravity. Heavy wet awning, located high above the transom, can adversely affect the stability of a small vessel. In sharp turns, the inertia of the mass of the awning can increase the roll of the boat. Therefore, for high-speed walks, it is recommended to use lightweight options or raise the awning in a position that minimizes resistance.
Instructions: Installation of the running tent yourself
If you decide to make or install an awning yourself, you'll need a clear plan of action. Mistakes in the design phase can cost the integrity of the boat. Below is a sequence of steps to install a universal awning on the arcs.
First, you need to identify the anchorage points. For PVC boats, these are usually special pockets sewn by the manufacturer, or the reinforcement points of the cylinder. If they are not there, you can use wrapping slings with buckles, but always with soft linings. Metal arcs should not touch the rubber directly without a gasket.
☑️ Checklist for tent installation
The fabric must be stretched evenly, without sagging where water can accumulate (“pool effect”), but also without excessive tension, which deforms the arcs. The fastening is carried out using laces, fastex belts or lightning. The combined method is preferable for the chassis: rigid fixation at the front and quick-removal mounts at the rear.
The final step is to test the stability. Rock the boat, mimicking excitement. The frame should not walk, and the fabric should fight against the interior detail. If done correctly, the awning will become an integral part of the boat, providing reliable protection.
The secret of durability of fasteners
Use polyester slings, not nylon. Nylon stretches heavily when wet, which causes the mounts to weaken in the rain, and the awning begins to clatter. Polyester maintains its size regardless of the humidity.
Care and storage of awning structure
The life of the awning depends on the conditions of its use and storage. After each release, especially if it was rainy or splashed awning, it must be dried. Wet cloth in rolled form is the ideal environment for the development of mold and fungus, which destroy the structure of the tissue and cause unpleasant odor.
Cleaning should be done with a soft brush and soap solution. Aggressive chemistrySolvents or hard brushes can damage the protective PU/PVC coating, depriving the fabric of water-repellent properties. If the fabric has become contaminated with fuel and lubricants, they must be removed immediately, since gasoline and oil dissolve many types of polymer coatings.
It is best to store the awning in a straightened form or loosely rolled up into a spacious bag in a dry room. It is not recommended to store the awning in a compressed state under heavy loads, as this can lead to the formation of crevices on the coating, which subsequently become cracking points.
The main enemy of the tent is not the sun or the water, but the dirt and moisture left in rolled form for storage. Always dry the tent before packaging!
Frequently Asked Questions (FAQ)
Can I use a running awning in winter at sub-zero temperatures?
Yes, you can if the fabric is designed for low temperatures (usually up to -40°C or -50°C). However, PVC materials become rigid in the cold, so you need to arrange and fold the awning extremely carefully so that you do not break the material or plastic elements of the fittings.
How to remove water if the awning still sagged and gained rain?
Do not press your sagging hand from the bottom to try to move the water to the edge, this can damage the seams or fabric. It is best to gently raise one of the corners of the awning or use a long stick with a soft tip to direct water towards the drain. Ideally, the design of the awning should initially exclude the formation of "pockets".
What is the difference between a parking and a running awning?
The chassis is streamlined, has reliable fastenings that withstand wind loads at speed, and is often equipped with observation windows. The parking awning is only designed to protect against dust and precipitation during parking, it fits tightly around the boat, does not have a rigid high frame and is not intended for use during movement.
Can I repair a broken awning on my own?
Small repairs are possible. For Oxford and PVC fabrics, there are special glue and patch remixes. It is important to degrease the surface and use adhesives designed specifically for your type of material (PU or PVC). For large tears, you should contact the awning workshop.
