Purchasing an inflatable boat is just the first step towards a full rest on the water, followed inevitably by the legal registration stage. Under current law, every small boat must be marked with a unique tail number that is applied on both sides of the bow. For owners of inflatable boats made of polyvinyl chloride, this process has its own technical features, because the standard fastening methods used for metal or fiberglass are not suitable here. PVC boat numbersIt is important to take into account not only the aesthetic component, but also the durability of application, as well as compliance with the requirements of GIMS.
The modern market offers many solutions, from simple stencils for self-application to ready-made self-adhesive stickers of increased strength. An error in the choice of material or technology can cause the labeling to be erased after the first season of active use, which will entail an administrative penalty when checking documents on the water. In this article, we will discuss in detail what types of marking exist, how to choose a reliable supplier and why the quality of the paint or film plays a crucial role in the safety of your registration mark.
It is important to understand that the tail number is not just a set of letters and numbers, but the official identifier of your vessel in the register of small craft, its loss or unreadability is equated with no registration, with all the ensuing legal consequences, so the choice of application method should be approached with the utmost responsibility, having studied all the options available and their specifications.
Legislative requirements for marking of small vessels
Before you go looking for where PVC boat numbersAccording to the rules of registration and accounting of small vessels, the tail number must be marked in a contrasting color at a distance of 1/4 of the length of the hull from the first step (nose) on both sides. The height of the signs must be at least 150 mm, and the width must be at least 100 mm, while the thickness of the font lines is regulated from 15 to 30 mm. Failure to comply with these parameters can be grounds for refusing registration or issuing a prescription by the inspector of the GIMS.
Particular attention should be paid to readability and stability of markings, the number should be clearly distinguishable at a distance and not erased during operation. PVC This creates certain difficulties, as the surface of the board is subject to constant deformation, friction on the berth and aggressive aquatic environment. Legislation does not prohibit the use of removable elements, but they must be securely secured and cannot be easily removed at the time of inspection without the use of a special tool.
⚠️ Attention: The use of indelible markers or ordinary stationery paint for the registration of the number is prohibited, as such methods do not provide the required durability and contrast.
It is also worth noting that the color of the room should contrast with the color of the side. If your boat is dark in color (gray, camouflage, blue), the number should be white or light gray. For light boats (white, beige), black or dark blue is used, this requirement is dictated by the need for rapid identification of the vessel by rescue services or law enforcement agencies in emergency situations.
Types of marking: stencils, stickers and engraving
When the owner has a task PVC boat numbersIt faces three major solutions: self-adhesive stickers, paint stencils and board stickers, each of which has its own advantages and disadvantages, which directly affect the end result and life of the marking.
The most popular and affordable way is vinyl stickers, which are ready-made signs cut out of a dense film with adhesive layers, and the main advantage of this approach is that it's easy to install: just degrease the surface, remove the protective layer and roll the number. Oracal or 3MThey have high PVC adhesion and UV resistance, but they also have a weak spot, mechanical damage, and if they come into frequent contact with rocks or snags, the edges of the stickers can start to peel off.
The second option is stencils, in which case you buy or make patterns that you apply to the special paint, which is considered more durable because the paint penetrates the material structure or forms a strong chemical bond with the surface. Inflatable boats use two-part polyurethane paints or specialized compounds based on chloro rubber. This number is almost impossible to erase by accident, but the process of applying it requires more time, skills and preparation.
The third, most radical method is to stick the plates on board during production or major repairs, in which a piece of cloth with the number already applied is welded into the structure of the boat, which provides maximum protection against tearing off, but requires professional equipment and skills in working with PVC. For the average user who wants to just register an existing boat, this method is the least suitable.
Material choice: vinyl, polyurethane or fabric
The quality of the material that makes up your future numbers directly determines how long they will last. PVC boat numbers For a long time, saving on the material of the base or coloring composition is strictly not recommended. Cheap analogues quickly fade in the sun, lose elasticity and begin to crack on the folds.
For self-adhesive options, the de facto standard is a calendered or cast vinyl film with a thickness of at least 80 microns. It must have a reinforced adhesive layer that is resistant to salt water and temperature changes. Oracal 641 and Oracal 751The first is for short- and medium-term outdoor advertising (life of 3-5 years), the second is for long-term use (up to 8-10 years). For a boat that will be kept outdoors or often operated, it is better to choose the second option.
If you choose to paint, the chemical composition of the paint is key. Conventional enamel or acrylic paints will not work, they will simply detach from the smooth PVC at the first deformation of the cylinder. You need to use specialized formulations containing active solvents that slightly "melt" the top layer of PVC, providing a monolithic clutch. Often these paints are sold complete with a primer (soil) that must be used to achieve the declared strength.
Before buying paint or film, check the compatibility of the chemical composition with the material of your boat. Some aggressive solvents can damage the protective UV layer of PVC fabric.
Also worth mentioning are the cloth plates that are sewn in or pasted, made of the same reinforced cloth as the boat itself, with a silk-printed or thermally printed image, which is the most "native" variant for PVC boats, since the temperature expansion coefficient of the room and the board is the same, which excludes detachment when heated in the sun.
Comparative table of application methods
Make it easier for you to make a decision and PVC boat numbers So we've developed a comparative analysis of the basic methods, and the table shows the key specifications that influence the choice.
| Parameter | Vinyl sticker | Painting (stencilling) | Tissue pasting |
|---|---|---|---|
| Difficulty of application | Low (you can do it yourself) | Medium (skills required) | Tall (workshop required) |
| Term of service | 3-7 years | 5-10 years | 10+ years (boat service life) |
| Resistance to abrasion | Medium | High. | Very high. |
| Cost of implementation | Low. | Medium | High. |
| Possibility of replacement | Easy. | Difficult (to be painted over) | Impossible without repairs |
The table shows that for most amateurs who do not plan to operate extremely rigidly, the optimal balance of price and quality is high-quality vinyl stickers, which allow you to quickly bring the boat into compliance with the requirements and if necessary, easily change the number, for example, when selling a boat or changing registration data.
Painting is chosen by those who value maximum reliability and are willing to spend time preparing the surface. Fabric pasting is the lot of professionals or those who order a boat with a number from the manufacturer. For an already operating vessel, this method is too time-consuming and expensive.
Instructions for self-deployment of the number
If you decide to save on the services of the workshop and apply the number yourself, you will need to follow the technology clearly. PVC-boat They're peeled off after a month, and it's very neat, but it's very home-based.
The first and most important step is to prepare the surface. The boat should be completely clean, dry and fat-free. Use special degreasings based on isopropyl alcohol or acetone (careful with acetone, test on an inconspicuous area!). You can not use gasoline or aggressive solvents that can damage the structure of PVC. After degreasing, do not touch the surface with your hands.
☑️ Preparation for the registration number
Then there's the sticking process. If you're using a screen film with a mounting film, first glue the entire block with the number to the board, make sure that the positioning is even. Then, without removing the mounting film, carefully roll the number with a rubber roller or a plastic card, expel all the air bubbles. The movements should go from center to edges. Then carefully, at an acute angle, remove the top mounting film. If any elements are left on it, return the film back and press the problem area harder.
⚠️ Attention: Do not try to apply numbers in the cold or in temperatures below +10 ° C. The adhesive layer of vinyl does not activate properly, and after a short time the number will begin to move away.
The technology is similar for stencil paint, but instead of rolling, you apply layers of paint, you press the stencil tightly to the surface (you can use paint tape to fix), and the paint is applied in thin layers with intermediate drying. A thick layer of paint can leak or dry for a long time, which will spoil the clarity of the boundaries.
Care for labeling and (FAQ)
After you could. PVC boat numbers And if you apply them successfully, it's important to take good care of the labeling during operation, and regular care will extend the life of the rooms and keep them presentable throughout the season.
The main rule is not to use abrasive cleaning products and hard brushes in the area of the room. When washing the boat after fishing, try not to rub the numbers with a sponge with an abrasive side. If you use the painting method, then after 2-3 years you may need to renew the top layer with varnish or re-apply the paint, as the pigment can burn out slightly under the influence of ultraviolet light.
What should I do if the room is damaged?
If a piece of vinyl sticker breaks off, you can try to carefully warm the edge with a hair dryer and press it down. If the damage is serious, it is easier to order a duplicate of the sign (numbers/letters only) and replace the defective element without changing the entire number. For painted rooms, there is a restoration kit that allows you to locally paint the chip.
Boat storage also affects the condition of the rooms: If possible, keep the vessel in a cover or indoors to minimize the impact of direct sunlight during downtime, especially for dark boats that can heat up to high temperatures in the summer, putting additional stress on the adhesive layer.
At the end of the section, we will give answers to frequently asked questions that will help to avoid typical mistakes.
Can I put a room on a wet boat?
Absolutely not. The surface should be perfectly dry. Even microscopic drops of water under the film will cause bubbles and loss of adhesion. If the boat is wet, dry the dryer or let it lie down in the sun.
Do I need to register the fact of the number?
No, you need to register only the boat itself and get the onboard number in GIMS. The method of application (sticker, paint) you choose yourself, the main thing is the compliance of size and readability with the GOST signs.
How much dried PVC paint?
The drying time depends on the type of paint and air temperature. Usually, the primary drying (stickiness) occurs in 30-60 minutes, but the full strength and chemical resistance of the coating is gained after 24-48 hours.
Where is the best place to book rooms?
It is best to contact specialized boating stores or advertising agencies with experience with vinyl sharp for cars and water transport. Avoid booking rooms in random printing houses where you may not know the requirements for PVC materials.
Can I wash the boat with a kerkerker after applying the number?
You can, but with caution. Do not direct the high pressure jet close to the edges of the room, especially in the first weeks after the sticker, until the glue has gained maximum strength.
Properly applied and quality number is a guarantee of no problems with the inspection of GIMS and the preservation of the value of the boat during resale.
To sum up, the choice of marking depends on your priorities: speed and simplicity (stickers) or maximum durability (painting), in any case, this stage cannot be ignored, since having a readable side number is a mandatory requirement for legal water vent.
