Operating an inflatable vessel in real-world conditions often confronts the owner with the need to protect themselves from water. Even in relatively calm weather, on planing, the headwind raises splash shafts, which at high speed turn into a cold shower. Nose awning It becomes not just an accessory for comfort, but an important element of safety, keeping equipment, electronics and passengers dry.
Modern manufacturers offer many options for ready-made solutions, but often they do not take into account the individual specifications of a particular model. PVC boatsThat's why many water-engineers are thinking about making their own or refining their own products, and if they're properly designed, they can change the way they swim beyond recognition.
In this article, we will discuss the technical nuances of fabric selection, fastening methods and design features that will create effective spray protection. You will learn how to avoid common design errors that can lead to sailing or damage to cylinders.
Why do you need a bow awning on a boat?
The main function of any awning installed in the bow is to cut off the water flow. When moving at speeds above 20 km / h, the water does not have time to flow down the sides and flies directly into the cockpit. Splash protection It is critical not only for dry clothing, but also for maintaining the health of navigation devices, batteries and personal belongings.
In addition, a well-designed awning acts as a windshield, and at high speeds, the oncoming airflow creates significant aerodynamic drag that tires the driver and passengers. Reducing air drag can save up to 10-15% of fuelThis is a huge cost over long distances.
And psychological comfort, too: the constant cold wind and water in the face make you squint and strain, which reduces attention on the water, and the presence of a transparent or opaque screen in the nose allows you to stay focused and enjoy the process of steering the boat, regardless of the weather conditions.
Material choice: Oxford, Tarpaulin or PVC
The water industry materials market offers several major options, each with its own advantages and disadvantages, depending on the budget, operating conditions and the requirements for the durability of the product. Oxford with a polyurethane or polyvinyl chloride coating.
- 🧵 Oxford 210D/420D Light and durable material, perfectly holds the shape, but requires additional impregnation for complete water resistance.
- 🛡️ Tarpluan (Tarpluan) - three-layer material with reinforcement, absolutely waterproof, resistant to ultraviolet light, but heavier and tougher in the cold.
- 💧 PVC boat Maximum strength and identity of the material of cylinders, but difficult to process and has a high cost.
When choosing the density of the fabric should focus on the size of the boat. For small craft up to 3.5 meters, the density of 200-300 g / m2 is quite enough. For larger boats, where the sailing area is large, it is better to use denser reinforced fabrics to avoid tears during wind gusts or careless handling.
An important parameter is water-repellent impregnation (PU or PVC). For nasal awnings that will constantly get wet, PVC coating is preferable, since it is not as susceptible to hydrolizu (destruction by moisture) as polyurethane. However, PU tissues are more elastic and behave better at low temperatures.
When buying fabric, pay attention to the underside: high-quality coating should not stick to your fingers and have a sharp chemical smell, indicating a violation of production technology.
Design features and forms of tents
The geometry of the bow awning has a direct impact on its efficiency and aerodynamics. The simplest shape is a flat screen that just stretches between the sides. However, this design creates strong turbulence and can work like a sail in side wind, which is dangerous for the stability of the boat.
A more advanced solution is a streamlined awning, often called a hood or a visor, which has a bulk structure that directs the flow of water and air up and down the sides, bending the cockpit, which requires the use of patterning and stitching together a few parts, but the result is worth it.
⚠️ Warning: Avoid creating horizontal areas on the top of the awning that will accumulate water from rain or splash, putting additional strain on the mounts and construction.
The most reliable method is the combination of a tight fixation in the nose (on ducks or a hinge beam) and a gentle stretch on the sides with slings, which allows you to compensate for the change in pressure in the cylinders when heated in the sun without the risk of mountings breaking off.
Instructions for installation and fastening
Installation of the bow awning requires care to avoid damaging both the accessory and the hull of the boat, and the main objective is to ensure a tight fit without a stretch that can deform the cylinders. The installation process can be divided into several logical steps.
☑️ Pre-installing check
First, the awning is laid out in the bow of the boat, and the fastenings in the area of the transom board or the nose funduke are fixed first, then the lateral slings are stretched. The important thing is to observe the symmetry: first, slightly pull one side, then the other, gradually increasing the force to elasticity.
For fixation on the hinge beam, special hooks or cords are often used, run through the luvers. If the awning involves installation on inflatable elements (for example, in a burst of a cylinder), you must make sure that the seams do not rub against the valves or joints of sections.
| Type of attachment | Materials | Reliability | Difficulty of installation |
|---|---|---|---|
| Hooked rubber bands | Latex/Resina | Medium | Low. |
| Fastex slings | nylon | High. | Medium |
| Lace in the luvers | polyester | Very high. | High. |
| Velcro straps (Velcro) | Textiles | Low. | Low. |
Never leave the awning stretched in the sun unless the boat is in use - heating the air in the cylinders can cause them to rupture or deform the seams.
Transparent inserts and visibility
One of the main problems with deaf nose awnings is the loss of visibility, where the driver can't see buoys, snags or other boats in the vicinity of the nose, and the solution is transparent inserts made of special materials.
The most common material for these windows is polyurethane film or reinforced polyethylene. Conventional PVC is less suitable for this purpose, because it quickly becomes cloudy, scratches and becomes brittle in the cold. A quality film must have ultraviolet protection, otherwise it will turn yellow in one season.
When sewing an awning, it is important to place the viewing windows correctly, they should be at the eye level of the seated driver, but not interfere with the view of the instruments, often making one large center panel or two side panels, depending on the design of the cockpit.
⚠️ Warning: Transparent inserts should not be washed with aggressive chemicals or abrasive sponges, use only soft cloth and soap solution, otherwise the film will lose transparency.
How to take care of transparent film?
To maintain the transparency and elasticity of the film in winter, it is recommended to treat it with special aerosols-antistatics, which will prevent the formation of microcracks when bending in the cold and reduce dust adhesion.
Independent sewing: patterns and nuances
Hand-made awnings are an opportunity to get a product that fits your boat perfectly, starting with taking measurements, and not relying on standard dimensions, because the geometry of inflatable boats of even one model can vary depending on pressure and temperature.
So the best way to create a pattern is to use soft material, like old sheets or cheap film, and if you try this on a boat, you can adjust the shape, add seams, and provide space for attachments, and only after you approve the layout, the pattern is transferred to the main fabric.
When sewing, be sure to use threads LL (Lavasanovy) or Capron High strength (number 40 and above) Cotton threads will rot in one season, and the seams are recommended to be glued with a special tape or smeared with a sealant for fabrics to prevent leakage through the holes from the needle.
Frequently Asked Questions (FAQ)
Can I use a bow awning in a strong side wind?
It is not recommended to use an awning in strong side winds (more than 10 m / s), since it works as a sail and can overturn a light boat. In such conditions, it is better to remove or dampen the tension as much as possible.
How to keep an awning in the off-season?
The awning should be thoroughly dried, cleaned of dirt and folded in a free form, avoiding cracks on transparent inserts, it is better to store in a dry room at room temperature, away from heating devices.
Do I need to treat the tent with water repellent sprays?
Modern materials like Oxford or Tarpaulin are already factory-impregnated, and the processing is only needed after a few seasons of use, when you notice that the fabric has started to get wet and heavy.
Does the awning affect the speed of the boat?
A properly designed streamlined awning has little to no effect on speed. A flat screen can create additional drag, but it is usually offset by driver comfort.
