Troubleshooting & FAQ

How many characters are included in the package?

The package contains four sets of A-Z letters and four sets of 0-9 numbers, totaling 144 individual decals. This is typically sufficient for registering multiple watercraft.

Do these decals meet regulatory requirements?

Yes, the 3-inch height and block-style font are designed to meet U.S. Coast Guard (USCG) and state-level requirements for boat registration numbers when applied correctly—on the forward half of the vessel and in a color that contrasts with the hull.

Are the decals durable enough for saltwater environments?

Absolutely. They are made from marine-grade vinyl that is UV-coated, waterproof, fuel-resistant, and scratch-resistant, making them suitable for both freshwater and saltwater conditions.

What is the best way to ensure straight and even application?

For a professional result, use a straight edge like a ruler and masking tape to create a level guideline on the hull before you begin. This helps you align each character perfectly.

Can I remove the decals without damaging the boat's surface?

Yes. While the adhesive is strong, the decals can be removed. Applying gentle heat from a hairdryer can help soften the adhesive, allowing you to peel them off. Any remaining residue can typically be cleaned with a marine-safe adhesive remover.

Are the letters and numbers individual, or are they on a single sheet?

All characters are individual die-cut decals, allowing you to create any custom registration number with appropriate spacing.
