Installation Notes

  1. Clean the application surface thoroughly, removing any dirt, oil, and wax to ensure proper adhesion.
  2. Identify the specific location on your vessel for registration numbers, typically on the forward half of the hull.
  3. Use a pencil or masking tape to mark a straight guideline for decal alignment.
  4. For accurate positioning, begin by applying the middle character of your registration number first.
  5. Apply remaining characters evenly spaced, working outward from the center.
  6. Ensure the registration characters are in a color that contrasts with your vessel's hull color to meet regulations.

Troubleshooting & FAQ

What do I get in one package?

The package contains four full sets of A-Z letters (104 total) and four full sets of 0-9 numbers (40 total), allowing you to create your registration ID with plenty of extras for future needs.

Are these decals compliant with boating regulations?

Yes, the 3-inch character height meets U.S. federal and state requirements for boat registration numbers when applied correctly in a contrasting color on the forward half of your vessel.

How do I ensure the numbers are straight?

For best results, use a strip of masking tape to create a straight guideline on the hull. We recommend starting with the middle character of your registration sequence to ensure even spacing on both sides.

What surfaces can I apply these to?

These decals are designed for smooth, non-porous surfaces such as painted fiberglass, metal, plastic, and glass, which are common on boat hulls and personal watercraft.
