Attaching Identification: Tagging Your Inflatable Boat

Attaching a registration number to an inflatable boat is a crucial aspect of maritime safety and legal compliance. While the specific requirements vary across regions, understanding the process of putting a tag on your inflatable boat is essential to avoid fines and ensure your vessel is legally recognised. This guide will provide a comprehensive overview of the steps involved in installing a registration number on your inflatable boat, ensuring it is easily identifiable and compliant with maritime laws.

Using stencils and paint

• Prepare the surface: Clean the area where you will apply the numbers. Use a mild detergent and water, then wipe it down with alcohol wipes to remove any residue. Ensure the surface is completely dry before proceeding.
• Position the stencil: After cleaning the surface, position your stencil in the desired spot. Secure it with masking tape to prevent movement during painting.
• Paint application: Use a small brush or sponge to apply marine-grade paint within the stencil. Be careful not to overload the brush to avoid paint bleeding under the stencil. Apply multiple thin coats if necessary, allowing each coat to dry before applying the next.
• Remove the stencil: Once the final coat of paint is dry, carefully remove the stencil. Clean up any edges with a small brush or waterproof marker if needed.
• Ensure straight and even spacing: Use a level and ruler to ensure your numbers are straight and evenly spaced. Double-check your measurements before removing the stencil.
• Visual inspection: Step back and visually inspect the numbers from a distance. This helps identify any alignment or spacing issues that may not be noticeable up close.

Some additional tips to consider:

• Use a flexible vinyl stencil product with a manufacturer-recommended vinyl spray paint.
• Go slowly and ensure the stencil is pressed down firmly onto the boat.
• Choose a paint that is suitable for inflatable boat materials, such as PVC or Hypalon. The paint should be waterproof, UV-resistant, and capable of withstanding marine environments.
• Consider applying a clear UV-resistant sealant over the painted area to protect the numbers from fading and peeling.
• Regularly inspect the registration numbers for wear or damage, especially after long periods of storage or rough water conditions.
• Keep a small amount of the original paint for touch-ups, and use a fine brush for precision.

By following these steps and tips, you can effectively use stencils and paint to apply registration numbers to your inflatable boat, ensuring durability, legibility, and compliance with regulations.

Attaching a plastic/metal number plate

Step 1: Prepare the Boat Surface

Before you begin, make sure you have all the necessary tools and materials, including the number plate, adhesive or glue, solvent (such as acetone or MEK), medium-grit sandpaper, clean rags, and disposable gloves. Start by inflating the hull of your boat and deciding on the placement of the number plate, ensuring it complies with any legal requirements. Outline the area where the plate will be installed with masking tape, then lightly scuff the surface with sandpaper to create a rough texture that will help the adhesive bond better. Finally, wipe away any grit or residue with a clean rag.

Step 2: Clean the Hull and Plate

Using a clean rag, scrub the outlined area on the hull and the back of the number plate with a solvent such as acetone or MEK. This will help remove any dirt, grease, or residue that may interfere with the adhesion. Wait 10 minutes, and then repeat the process to ensure a thorough cleaning. Acetone evaporates quickly, so you may need to work in smaller areas and dampen the rag frequently.

Step 3: Apply the Adhesive

Brush a thin layer of PVC adhesive or glue to both the prepared area on the hull and the back of the number plate. Let the adhesive dry for about 10 minutes, and then apply a second thin coat to each surface. It is recommended to install one plate at a time to ensure the best results.

Step 4: Install the Number Plate

Starting at one end of the plate, slowly and carefully lay it into position, using the masking tape outline as your guide. The adhesive will bond almost instantly, so be precise in your placement. Once the plate is in position, firmly rub it, starting from the centre and working towards the edges, to remove any air bubbles. Remove the masking tape and let the adhesive cure for at least 48 hours before using the boat.

Additional Tips:

• Always wear disposable gloves to protect your hands from solvents and adhesives.
• If using a glue-on number plate, follow the instructions and recommendations provided by the manufacturer.
• For self-adhesive number plates, ensure the inflatable boat is kept inflated for the best results.
• If you are unsure about the material of your inflatable boat, you can use acetone to test it. Wipe a small amount of acetone on an inconspicuous area of the boat; if it gets sticky, it is likely made of PVC. If it does not react, it is probably made of Hypalon or another synthetic rubber material.

Using a permanent marker

Prepare the Boat Surface:

Clean the area on the boat where you will write the registration number. Use a mild detergent or soap and water to wipe down the surface, ensuring it is free of any dirt, grease, or residue. You may also want to lightly sand or scuff the surface with medium-grit sandpaper to create a slightly rough texture that will help the ink adhere better.

Mark the Position:

Determine the correct position for the registration number, considering legal requirements for its location and distance from the bow. Use a ruler or tape measure for accuracy. Mark the spot lightly with a pencil or removable marker to ensure proper alignment before writing the number.

• Write the Registration Number:
• Allow Drying and Reapply if Necessary:

Let the ink dry completely before using the boat. If the colour is too light or uneven, you may need to apply a second coat. Carefully go over the numbers again with the permanent marker, ensuring an even and bold appearance.

Consider a Protective Coating:

To protect the registration number from wear and water exposure, consider applying a clear, UV-resistant sealant over the marked area. This will help prevent the ink from fading due to sun exposure and protect it from the elements.

Regular Maintenance:

Regularly inspect the registration number for any signs of wear or damage, especially after periods of storage or exposure to rough water conditions. If the number starts to fade or smudge, touch it up with the permanent marker.

Compliance and Legibility:

Ensure that your registration number complies with local regulations regarding size, colour, and placement. It should be at least three inches high, in a bold and block font, and placed in a highly visible location on the boat, typically on the forward part of the boat, on both sides.

Using glue or adhesive

Surface Preparation:

Start by cleaning the area where you will apply the numbers. Use a mild detergent or a solvent like acetone or MEK (methyl ethyl ketone) to ensure the surface is free of any residue. Wipe the area with a clean rag and let it dry completely before proceeding.

Positioning the Numbers:

Determine the correct position for the numbers by considering legal requirements for their location and distance from the bow. Use a measuring tape, ruler, or tape measure to mark the spot accurately. Most regulations require the numbers to be placed on the forward part of the boat, ensuring visibility when the boat is in the water.

Applying the Adhesive:

You can purchase custom flexible plates with adhesive backing from specialised websites like BoatNumberPlate.com. These plates are designed to stick to both Hypalon and PVC surfaces. Apply a thin layer of the recommended adhesive, such as Polymarine Ltd. Inflatable Boat Adhesive, to the boat area and the back of the plate. Let it dry for about 10 minutes, and then apply a second thin coat.

Installing the Plate:

Carefully lay the plate into position, using the outline you created with masking tape as a guide. The adhesive bonds quickly, so make sure to work slowly and carefully. Once the plate is down, firmly rub it, starting from the centre and working towards the edges, to remove any air bubbles. Remove the masking tape and let the adhesive cure for the recommended amount of time, typically around 48 hours.

Maintenance and Touch-Ups:

To maintain the visibility of your registration numbers, consider applying a clear UV-resistant sealant over the adhesive plate to protect it from fading and peeling due to sun exposure and water wear. Regularly inspect the numbers for any signs of wear or damage, especially after extended storage or rough water conditions. Keep spare numbers on hand to replace any that become damaged or start to peel.

Applying a protective coating

Prepare the Boat Surface:

Before applying any coating, it's essential to clean the boat thoroughly. Use a mild detergent or a specialised inflatable boat cleaner to remove any dirt, grime, or oxidation. Ensure that the boat is dry before proceeding to the next step.

Choose the Right Protective Coating:

There are various protective coatings available on the market, specifically designed for inflatable boats. These coatings are typically made from flexible materials that can expand and contract as the boat is inflated and deflated. You can opt for a water-based vinyl paint, a two-part system with a base coat and a top coat, or a liquid rubber coating. Consider the type of fabric your boat is made of (PVC or Hypalon) and choose a coating that is compatible and offers strong adhesion.

Apply the Coating:

Follow the instructions provided with your chosen protective coating. Most coatings will require multiple thin coats, allowing adequate drying time between each application. Use a brush, roller, or spray equipment to apply the coating, ensuring even coverage across the boat's surface.

Cure and Dry:

After applying the protective coating, allow ample time for it to cure and dry completely. The curing time can vary depending on the product and environmental conditions, especially humidity. Refer to the manufacturer's instructions for specific curing and drying guidelines.

Maintain Your Boat:

Once the protective coating has been applied and cured, it's important to maintain your inflatable boat properly. Avoid using abrasive materials or harsh chemicals when cleaning, as these can damage the coating. Stick to mild detergents and soft cloths or sponges. Regularly inspect the coating for any signs of wear or damage, especially after extended periods of storage or exposure to rough water conditions.

Reapply as Needed:

Over time, the protective coating may need to be reapplied to maintain its effectiveness. Keep a small amount of the coating product for touch-ups, and consider reapplying a new coat annually or as recommended by the manufacturer.

By following these steps and choosing a suitable protective coating, you can enhance the durability and appearance of your inflatable boat, ensuring it remains in top condition for years to come.
