The hot summer sun can turn a pleasant walk into a beautiful place. floatboat The lack of a canopy often causes water transport owners to either interrupt their forays or risk heat stroke and sunburn. bionitope It has become one of the most popular elements of tuning, providing the necessary comfort in open water.
This one tent Not only does it create shade, it also protects against sudden rain, allowing you to stay on the water even when the weather gets worse. A properly designed structure is not afraid of wind gusts and does not create unnecessary resistance when driving. In this article, we will discuss in detail how to choose a ready-made solution or make a ready-made one. frame Your boat will be the perfect place to relax.
Competent installation biomini It requires taking into account many nuances, from the choice of material to the mounting points on the sides. The optimal angle of inclination of the frame is 30-45 degrees, which provides maximum shade area at noon and minimal sailing resistance. Let’s look at the main aspects that will help you avoid common mistakes when upgrading your boat.
⚠️ Attention: Installing awning on a PVC boat requires special care when attaching the pillars. Excessive tension or the wrong angle can damage the cylinders, so use special linings and soft fasteners.
Design features and advantages of the canopy
Classical. bionitope It's a folding structure, which is a metal frame and a tent that's pulled over it, and unlike a capital roof, it allows you to fold the canopy quickly if you want to walk under a low bridge or just remove the shadow to sunbathe. stainless steel or aluminum, which is resistant to corrosion in salt water.
The main advantage is that you can adjust the position. tent It's a complete solution, whether it's lifted for better ventilation or folded into a hiking position in seconds, which makes it a versatile solution for both fishing, where mobility is needed, and for family walks that require constant comfort. Modern models often come with extra features that extend functionality.
It is important to note that the quality frame If you're driving at high speed, the wind puts a lot of pressure on the structure, and if you're planning to be active, you should look at models with extra struts or reinforced hinges. Fabric It also plays a role: it must be not only waterproof, but also resistant to ultraviolet light.
- ☀️ Protection from the scorching sun and harmful UV radiation during long transitions.
- 🌧️ The ability to stay dry in sudden rainfall or squall wind.
- ⚓ Universal design suitable for PVC boats and small boats.
Selection of materials: fabric and metal
Your durability bionitope It depends on the quality of the materials selected. AISI 304 stainless steel The latter option is preferable for seawater, because it contains molybdenum, which increases corrosion resistance. Aluminum pipes are lighter, but they are less durable on the kink and require thicker walls, which increases their diameter.
As for the fabric coating, here the uncontested leader remains. oxford It's a polyurethane or PVC coating, and it has to be at least 400 to 600 den to withstand mechanical stress and wind, and cheap polyester products burn out quickly and start to leak moisture after the first season of active use, and the color of the fabric also matters: lighter colors get hotter, but they get dirty faster.
When choosing fittings So, you should give preference to brass or stainless steel elements. Plastic latches and carbines in the sun become brittle and can burst at the wrong time. Seams on the awning should be glued or boiled, because a regular thread will rot in a couple of years. tent It lasts 5-7 years or more with proper care.
Secrets of Durability of Fabric
Oxford PU-coated fabric (polyurethane) is more elastic in the cold than PVC. If you plan to store the boat in an unheated garage in the winter, choose a PU coating to avoid cracking the fabric when folding.
Manufacture of the frame DIY
Creation frame It is a great way to save money and get a design that is ideal for the dimensions of your boat. To work, you will need stainless steel pipes with a diameter of 20-25 mm with a wall thickness of 1-1.5 mm. The connection of elements is usually made with fittings (tribes, corners, hinges), which allows you to assemble the structure without welding, using only bolt connections.
The assembly process begins with the creation of a drawing or a diagram. boat The standard height of the biminitope is about 120-140 cm from the floor level, which allows even a tall person to sit comfortably under it, all pipe cuts must be made exactly at 90 degrees so that the fittings sit tightly and without distortion.
Diagonal struts are used to make the structure rigid, and they prevent the frame from folding forward or backward under the influence of the wind. If you use welding, be sure to clean the welds and treat them with paste to protect against rust, even if it's stainless steel. The frame should be assembled completely and checked for resistance to stretching the fabric.
☑️ Frame assembly tools
Below is a table with approximate pipe sizes for a standard biminitope at 3-4 meters:
| Element of construction | Pipe diameter (mm) | Number (s) | Note |
|---|---|---|---|
| Upper arc. | 25 | 3-4 | Forms a roof. |
| Vertical struts | 25 | 4 | Support elements |
| Lower anchorages | 20 | 4 | For installation on board |
| Struttings | 20 | 2 | Diagonal rigidity |
Instructions for installation on the PVC boat
Installation bionitope And the first step is to put in the mounting glasses or brackets, and PVC boats are usually using special platforms that are attached to the balloon or attached to the squirrel board. The awning will be skewed.
After fixing the bases, vertical pillars are inserted into them. frameMake sure that the bottom ends of the pillars do not have sharp edges that can pierce the balloon when rolling. For added security, you can put rubber plugs on the ends of the pipes or wrap them with a soft material, then the frame is laid out and fixed in the upper position.
The final stage is a stretch. tentThe fabric is placed on the upper arcs and fixed with Velcro, cords or luvers. The tension must be uniform so that the fabric does not slam in the wind, which will quickly cause it to wear out. Check all hinges in the open and closed position.
⚠️ Warning: Never leave a biminitop fully deployed during storm warning or in strong gusty winds. The sailing structure can flip a light boat or rip mounts from cylinders.
Use carbine slings to temporarily fix the biminitopes in the folded position, which will prevent them from opening spontaneously while driving at high speed.
Tent care and frame maintenance
To yours. bionitope It's been in the service of many years, and it needs to be properly cared for, and after every trip, especially on seawater, it's advisable to rinse the frame and the fabric with fresh water, and when it's dried on metal, it creates an aggressive environment that can destroy even the most powerful elements. stainless-molder The fabric must be cleaned with a soft brush using special means for synthetic materials.
You should store the canopy in a dry, ventilated place. tentThe metal joints and bolt joints are recommended to be lubricated periodically with silicone lubrication or WD-40 to prevent acidification.
Regularly check the condition of the seams and attachments. The appearance of small scuffs on the fabric can be eliminated with the help of special repair kits for PVC and Oxford. Timely repair of small defects prolongs the life of the product at times. Frame It should also be inspected for cracks in welds or tube deformities.
- 🧼 Wash the awning with only mild detergents, avoiding aggressive chemicals and solvents.
- 🌬️ Before packaging for long-term storage, be sure to dry the fabric until completely dry.
- 🔧 Once a season, check the tightening of all bolt joints and fittings.
Proper storage of biminitopes in winter (in straightened or neatly folded form in a case) increases the life of the fabric by 30-40%.
Alternative solutions and modernization
Classical. bionitope It's not the only solution for sun protection, there are hard top models that provide better noise insulation and heat insulation, but they're heavier and harder to install, and there are also combinations where the front of the awning is lowered to form a windscreen, which is true for cold weather.
Upgrade the standard frame You can add LED tape around the perimeter of the upper arc, which will provide lighting for the cockpit at night without having to install separate lights, and another useful addition is the pockets for small things that are sewn into the inner tent racks.
For lovers of fishing, it is important to install holders for rods directly on the racks. bionitopeThis frees up space in the boat and allows you to have gear at hand, and the main thing in the modernization is not to disturb the balance of the boat and not create stress points in the fabric elements.
How to calculate the height of biminitopes?
The height should be such that in a sitting position above the head there is a minimum of 15-20 cm of free space. For boats with a central steering wheel (console), the height is calculated from the highest point of the console.
Can I use biminitope in winter?
You can use tissue biminitope in winter, but at temperatures below -15°C, the Oxford and PVC fabrics become stiff and brittle. It is strictly forbidden to fold or spread the canopy in the cold - it can crack.
What do I do if the awning sags?
The sagging is usually caused by loosening of the attachments or stretching of the fabric, the first is to tighten the belts or bolts, and if the fabric is stretched, it will only help to stretch or replace the tent with a new one, because synthetic fibers tend to stretch under load.
Do I need to remove the biminitope when washing the boat?
When washing a boat with a kerkerker, it is better to fold or remove a biminitope, since a high-pressure jet can damage the water-repellent impregnation of the fabric or drive water inside the frame pipes, which will lead to corrosion from the inside.
