Buying Guide
What should I consider when choosing hull-number decals?
Certification and legality: Ensure the kit is USCG compliant and matches your state’s size and visibility requirements. Material durability matters: four-mil vinyl with UV coating lasts longer in sun and saltwater.
Color and finish: How to match your hull?
Contrast matters. Lighter hulls benefit from darker lettering, while darker hulls may need light colors. Gradient or two-tone options can provide OEM-like aesthetics but verify legibility from a distance.
Completeness and spacing
146-piece sets typically include enough letters and numbers for multiple configurations. Confirm whether you need both port and starboard sets. Check whether the kit includes the full A–Z and 0–9 sets for your registration code.
Ease of application
Peel-and-place designs simplify installation. Look for decals with a protective coating to resist fuel spills and abrasions. Some kits mention that international variants may have different labeling or instructions; ensure local compatibility.
Maintenance and replacement
Choose UV-coated vinyl to minimize fading. If you anticipate rebranding or changing registration numbers, ensure the kit provides enough characters for potential updates without purchasing a new set.
