STIFFIE Uniline Black 3″ Boat & PWC Registration Decals
Best for: Small boats and PWCs that need clear USCG-compliant numbers. This kit includes four sets of numbers and letters (0-9, A-Z), all 3 inches tall. It is 100% made in the USA and designed to meet Coast Guard guidelines. The durability comes from durable vinyl designed to resist outdoor conditions. Use this if you want ready-to-apply, uniform markings without drafting custom decals.
Caution: The data notes 146 decals total; consider storage or portioning if you only need a subset for a specific project.
Hardline USA Series 350 Boat Lettering & Registration Decal Kit
Best for: Boats requiring a full high-visibility black decal set with durability. This 3-inch kit is fuel-resistant and UV coated to protect against sun exposure and fading. It follows US Coast Guard guidelines and includes a solid black outline for legibility on dark hulls or waterline areas. Choose this if you need a rugged, comprehensive kit for vessel registrations and names.
Limitation: May be more than needed for small crafts with limited labeling needs; plan your lettering layout before applying.
Hardline USA Series 200 Factory Matched 3-Inch Kit
Best for: Boats and PWCs needing smooth, legible black lettering with reliable UV protection. The factory-matched set ensures cohesive style, and the fuel- and fade-resistant vinyl helps maintain appearance over seasons. It’s ideal for retrofits or new registrations where clean, consistent typeface matters.
Limitation: Solid black font may not contrast well on very dark hulls; plan contrasting outlines if needed for visibility.
STIFFIE Whipline Metallic Silver/Black 3″ Decals
Best for: Boats and PWCs seeking a premium look with metallic accents while staying within USCG guidelines. This set mirrors the Uniline in size and composition but adds metallic styling for enhanced visibility and style. The decals are 100% made in the USA and contain comprehensive number/letter options (146 decals).
Caution: Metallic finishes can require careful handling to prevent scratching during installation.
Attwood 14142-7 Waterproof Vinyl Letter & Number Kit
Best for: New registrations and quick replacements where reliable, sturdy lettering is essential. The kit features tough, waterproof vinyl that resists scratches and fading, with a pressure-sensitive label design for easy, fast application. It adheres to US Coast Guard guidelines, making it a practical choice for primary registration decals or vessel identification panels.
Limitation: Some users may prefer pre-measured, factory-matched sets for precise layouts on larger boats.
Buying Guide: Key Considerations for Boat Sticker Purchases
- USCG Compliance: Ensure the decals meet Coast Guard guidelines for readability, size, and placement.

- Installation: Preference for pressure-sensitive or self-adhesive decals; ensure surface is clean and dry for best adhesion.
- Aesthetic and Visibility: Consider solid black, metallic accents, or outlined letters to improve legibility from a distance.
- Maintenance: Favor vinyl with fade and scratch resistance for longer intervals between replacements.
