Installation Notes
- Wash hands before applying decals.
- Clean the application surface with a boat engine cleaner, ensuring it is free of any dirt, oil, or wax.
- Locate the appropriate registration area. Federal requirements mandate that registration letters and numbers must be adhered to the forward half of the vessel in a contrasting color.
- Use a pencil or masking tape with a straight edge to create a guideline for alignment.
- Begin with the middle numeral of your registration number, peeling it and positioning it at the designated location.
- Work towards the left side first, then the right, spacing all characters evenly.
Troubleshooting & FAQ
Are these decals compliant with US Coast Guard regulations?
Yes, the 3-inch height of the characters meets the federal requirements for registration decal size on vessels.
What surfaces can I apply these stickers to?
These decals are designed for smooth, non-porous surfaces common on watercraft, including plastic, metal, and gelcoat. Ensure the surface is thoroughly cleaned and dry before application for best results.
How do I ensure the registration numbers are applied straight?
We recommend using a straight edge and masking tape to create a level guideline on the hull. Apply the center character first, then work your way outwards to maintain even spacing and alignment.
How durable are these decals against sun and water?
The decals are crafted from premium outdoor vinyl and feature a UV clear coating, making them resistant to fading from sun exposure, water damage, fuel spillage, and scratches.
Is it easy to remove the decals if I make a mistake?
The adhesive is permanent and designed for long-term use. While they can be removed with heat and a scraper, it is best to position them carefully during the initial application.
Can I use these for other purposes besides registration numbers?
Absolutely. With four complete sets of letters and numbers, you can use them to name your boat, label equipment, or for other custom identification needs.
