Buying Guide: Key Considerations For Boat Decal Letters
What size should I choose? Typical registration numbers are sized to meet local regulations; 3-inch height is common for many boats and PWC. If you need higher visibility on a larger hull, consider multiple lines of numbers with contrasting colors.
Color and contrast matter. Black and white decals are the most legible against most hull colors; lighter backgrounds often benefit from darker lettering, while dark hulls may require white or bright colors for readability.
Durability features to look for. UV coating protects against sun fading; fuel and scratch resistance helps in saltwater environments; waterproof adhesives reduce peeling after waves and cleaning.
USCG compliance. Ensure the kit includes the correct letter and number sets and aligns with USCG guidelines for registration visibility and size.
Ease of installation. Peel‑and‑stick kits save time, but you should check for clear alignment marks or pre‑cut pieces, especially for curved hull surfaces.
Budget and coverage. A 146‑piece set provides ample characters for most standard registrations. If you need extra letters or digits for custom names, verify the kit’s content before purchasing.
