Small boat owners, whether they're compact inflatable boats or solid boats, eventually have to register their craft, and it's not just a bureaucratic procedure, it's a legal requirement to identify a boat on the water. tail-roomThe aircraft must be carried on board according to strict regulations, and errors in this process can lead to conflicts with inspectors and financial losses.
The labeling process requires careful consideration of materials and character geometry. Incorrectly selected fonts or poor-quality paint can cause the number to become unreadable after the first season. In this article, we will discuss in detail all the stages of application, current requirements. GIME technical nuances that will help to avoid common errors when self-labeling.
Compliance is not only a way to avoid fines, it is also a matter of water safety, a clearly visible number that allows rescue services to quickly identify a vessel in an emergency, so it is worth approaching the issue with the most responsibly, using proven techniques and quality supplies.
Regulatory requirements and standards of design
Before you pick up a brush or airbrush, you need to clearly understand what the law requires. According to the rules for registration of small craft, the number consists of an alphanumeric combination assigned when registering, the main requirement is that symbols can be readable from a distance of at least 50 meters under normal weather conditions. font size and contrast.
The height of the symbols may not be less than 150 mm and the width less than 100 mm. If the design features of the vessel do not allow the placement of the number of such dimensions, a decrease is allowed, but not more than 10%. However, for standard PVC boats and metal boats, the basic dimensions are mandatory. Color is also important: it should contrast with the background of the board, ensuring maximum visibility.
⚠️ Note: The use of decorative fonts, curls or stylizations that make reading difficult is prohibited. The inspector must read the number instantly, without having to peer or guess where one letter ends and another begins.
The room is also regulated, and it is applied on both sides in the bow of the vessel. flat-bar Or above it, the main thing is that the symbols are in one line and not be broken by structural elements such as ducks or linear racks. For inflatable boats, often choose a place on the cylinder immediately behind the bow amplification.
Selection of materials: how to apply the number
Choosing the right material is half the success. Other types of hulls require different approaches. PVC Specialized polyurethane-based paints or ready-made stickers are ideally suited. The paint should have high elasticity so that when blowing and inflating the balloon, the coating does not crack or collapse.
Metal and plastic boat owners should look to two-part enamel or epoxy paints to create a strong, chemically resistant film that is not afraid of gasoline, oil or long-term exposure to ultraviolet. Normal nitro paint or acrylic for interior work will quickly become useless, losing color and starting to peel.
The alternative to hand-painting is vinyl stickers, which are convenient because they don't take time to dry and can be replaced at any time. However, cheap vinyl, when exposed to salt water and the sun, quickly burns out and peels off. calender-film with lamination, the service life of which is 5-7 years.
For inflatable boats, be sure to degrease the surface with a special PVC compound before applying paint to ensure maximum adhesion and prevent the detachment of the room in the future.
Surface preparation and stencil creation
The quality of surface preparation directly affects the durability of the applied number. Regardless of the material of the case, the surface must be absolutely clean and fat-free. For PVC, you use alcohol solutions or special cleaners, for metal, acetone or white spirit. Any traces of dirt, fat or old coating will lead to defects.
Creating a stencil is a critical step. You can buy stencils from the store, but it's often more convenient to make them yourself. It uses a dense film or laminated cardboard. Symbols are cut with a stationery knife on a hard surface. It's important to leave the bars in letters like "A," "O," "R" so that the interior parts don't fall out.
When marking the place of application, use paint tape and level. Even a small blockage of the line will be conspicuous and can be regarded as a violation. Stap the stencil with paint tape so that it is firmly attached to the surface, especially at the edges of the symbols, so that the paint does not flow under them.
☑️ Preparation for the registration number
Technology of applying the number step by step
The application process requires care and patience. If you use paint, apply it in thin layers. The first layer may not be completely covert, that's OK. The main task is to create a base. The second and third layers are applied after the previous one has completely dryed out. Using a sponge or tampon instead of a brush helps avoid undercurrents and provides a more uniform coating.
When working with aerosol cans, keep them 20-30 cm from the surface. Sharp movements can lead to droplets that spread under the stencil. Movements should be smooth, left to right and back. After removing the stencil, let the paint dry completely according to the manufacturer's instructions, usually this takes 24 to 48 hours.
For stickers, the process is simpler: after degreasing and marking, the film is applied to the board and smoothed from center to edge with a racket or a plastic card. It is important to expel all the air bubbles. If the bubble is left, it can be gently punctured with a thin needle and smoothed out.
⚠️ Warning: Do not try to accelerate drying with a hair dryer or heat, especially on PVC. Local overheating can warp the boat material or cause paint to swell, which will spoil the entire look of the room.
What to do if the paint is leaking?
If you notice a leak immediately, carefully remove it with a dry cotton swab, without smearing. If the paint is already dry, you will have to wait for complete drying, then carefully clean the defect with fine sandpaper and paint over again, using a stencil to protect adjacent areas.
Table of conformity of sizes and materials
To systematize the requirements, it is convenient to use a summary table that will help you quickly navigate the parameters for different types of boats and materials.
| Type of boat | Recommended material | Min. symbol height | Resistance to abrasion |
|---|---|---|---|
| PVC (inflatable) | Polyurethane paint / Vinyl | 150 mm | High (with elastic basis) |
| aluminum | Two-component enamel | 150 mm | Very high. |
| Fiberglass | Epoxy paint/Gelcoat | 150 mm | High. |
| Tree. | Oil/Alkyd paint | 150 mm | Medium (requires an update) |
As you can see from the table, there is no universal solution. fiberglass Boats often use gelcoats, which are embedded in the structure of the hull, making the room almost eternal. Wooden boats require regular updating of the coating, as the tree "breathes" and changes size from moisture.
Typical errors and ways to fix them
One of the most common mistakes is saving on preparation, and trying to put a number on a dusty or wet side is doomed to failure, and the dust will create roughness, and the moisture will prevent the paint from clinging to the surface, and in a couple of weeks the room will start to fall off in layers.
The second common problem is the font's disproportion, and some owners try to squeeze a long number into a small space by narrowing the letters, which makes the number unreadable and is a direct violation of the rules. GIMEIf space is scarce, it is better to use a font with a smaller interletter spacing, but keep the width of the characters themselves.
The quality of surface degreasing determines 90 percent of the success, and even microscopic particles of fat or silicone could become the center of degreasing in the future.
The contrast requirement is also often ignored: a white number on a light gray side or a black number on a dark blue side will be poorly distinguishable, and in such cases, you need to use a different color edge (contour) at least 10% of the width of the symbol to highlight the number against the general background.
Liability and inspection by the inspector
The absence of a number or its non-compliance with the rules entails administrative liability: GIMS inspectors conduct routine raids, especially on weekends and holidays. The penalty for not registering or incorrectly marking can be substantial, not to mention detaining the vessel until violations are corrected.
The check is usually quick: the inspector checks the number on board with the data on the boat's ticket, if the number is not read, erased or taped, this equates to its absence, so the state of the marking should be monitored regularly, especially after winter storage or active season.
⚠️ Warning: The sealing of the room with awnings, equipment or protective linings while driving is prohibited. The room must be open for viewing at any time of the voyage.
It's the owner's responsibility to update the faded room in a timely manner, and if the paint starts to fade, it's better to prepare the stencil and refresh the symbols in advance than to explain to the inspector on the water. It will take a little time, but it will save nerves and budget.
Can I use different sized letters?
No, all characters in the room must be the same height and width (proportional) and the use of different font sizes for letters and numbers is prohibited by the design rules, as this makes it difficult to read and identify the vessel visually.
Do I need to certify the number with the inspector?
No, you don't have to verify that the paint or the sticker is applied, the inspector checks that the number already marked is in line with the documents when inspecting the vessel, the main thing is that the symbols are exactly the same as the data on the boat's ticket.
What to do if the number is damaged during operation?
You need to restore the readability of the number as quickly as possible, you can use temporary stickers or gently paint the damaged area, operating a vessel with an unreadable number equates to its absence and incurs a fine.
Is it allowed to put a number on the transom of the boat?
No, GIMS rules apply the tail number strictly on the bow of the boat, and the application on the transom (feed) is not considered to meet the marking requirement, although many owners duplicate the number there for convenience.
What type of font is considered standard for the number?
It is recommended to use simple serif-free chopped fonts (such as Arial or GOST fonts for technical documentation), the main requirement is clarity and the absence of decorative elements, rather than a specific font name.
