Installation Notes
- Wash your hands before applying decals.
- Clean the surface where decals will be applied, ensuring it is free of dirt, oil, and wax for best adhesion.
- Locate the specific areas for registration numbers as designated in your owner's manual. Federal regulations mandate that registration letters and numbers must be adhered to the forward half of the vessel in contrasting colors.
- Use a pencil or masking tape with a straight edge to lightly scribe a guide line for straight alignment.
- Begin with the middle numeral of your registration number to ensure centered placement.
- Peel the decal from its backing and carefully position it at the designated location.
- Continue applying characters, working to the left side first and spacing them evenly.
Troubleshooting & FAQ
Can these decals be used for official boat registration?
Yes. The 3-inch height meets USCG requirements for recreational vessels. They are designed specifically to replace or apply hull registration numbers. Always verify local and federal regulations for specific placement and color contrast requirements.
How do these decals hold up against saltwater and sun?
The decals are made from marine-grade, UV-resistant vinyl with a permanent adhesive. They are designed to resist fading, scratching, and damage from fuel or saltwater, ensuring long-term durability in typical marine environments.
What is the best way to ensure the decals are aligned properly?
For best results, use a straight edge and masking tape or a non-permanent pencil to create a level guide line on the hull before you begin. Starting with the middle character of your registration number can also help achieve even spacing.
Are the decals removable?
These decals are designed for single-use with a permanent adhesive. While they can be removed with heat and a scraper, they are not reusable and may leave residue behind that will need to be cleaned off.
What surfaces can I apply these decals to?
They are recommended for smooth, non-porous surfaces such as fiberglass, metal, and plastic. Ensure the surface is thoroughly cleaned and dried before application for optimal adhesion.
My decal is peeling. What went wrong?
Peeling is almost always caused by improper surface preparation. The application area must be completely free of wax, oil, or dirt. Clean the surface with a suitable solvent or degreaser and ensure it is fully dry before applying the decals.
