Buying Guide
- What size and style do I need? Consider hull surface, color, and visibility requirements. 3″ decals work well on mid-sized hulls; larger vessels may benefit from bigger numbers.
- Is the vinyl UV- and fuel-resistant important? For sun-exposed and fuel-rich environments, choose UV-coated, fuel-resistant vinyl to prevent fading and peeling.
- Do I need single-color or multi-color sets? Solid colors simplify matching brand colors; mixed colors support more design flexibility.
- Two-sided decals or single-sided? Two-sided sets simplify symmetrical branding, especially on boats with visible both sides.
- Is a transfer aid important? Clear transfer tape improves alignment and reduces misplacement during installation.
- Are there regulatory considerations? Ensure the kit meets USCG lettering guidelines and hull registration requirements for your vessel.
FAQ
