Buying Guide
What to consider when choosing boat registration numbers stickers:
- USCG Compliance: Ensure the kit explicitly states USCG compliance for lettering size and spacing.
- Durability: Look for UV coating, fuel resistance, and scratch resistance to withstand sun, salt, and abrasion.
- Color and Contrast: Choose colors that maximize legibility against your hull color and waterline visibility from a distance.
- Font and Size: Check the available font styles and confirm 3-inch height is appropriate for your vessel class and regulations.
- Adhesive Quality: A strong waterproof adhesive reduces peeling; peel-and-apply options speed up installation but ensure careful alignment.
- Bundle Size: Most sets include 146 decals; confirm you receive enough characters (numbers and letters) to meet your registration numbers.
- Application Aids: Transfer tape and clear instructions simplify alignment on curved or riveted surfaces.
- International vs Local Terms: Some products note variations; ensure you’re selecting a kit compatible with your locale and regulations.
