Hardline Products Boat Registration Kit — 3 in Silver/Black Vinyl Decals, UV-Resistant & USCG-Compliant

This kit is engineered to give your boat, PWC, or kayak a clean, factory-installed appearance while meeting legal visibility standards. Each decal is precision-cut from 4-mil marine-grade vinyl and finished with a UV-gloss topcoat to resist fading, chemicals, and abrasion. The Series 400 set includes multiple alphabet and number sets so you can mark both sides of your hull with matching style and spare characters for repairs or reconfiguration.

How does the Series 400 hold up to sun, salt, and fuel?

The decals use a UV-protective gloss layer and a chemically resistant vinyl core to minimize color loss and surface degradation over time. They resist staining from gasoline and other common marine contaminants and stand up to occasional scrubbing during cleaning.

• 4-mil marine-grade vinyl with UV-gloss topcoat
• Lead-free ink and chemical-resistant finish
• Designed to resist fading, fuel spills, and saltwater corrosion

Will these decals stick to my boat's material and shape?

Yes—Hardline’s Super-Stick Adhesive is formulated to bond to a wide range of hull surfaces, including complex contours and textured gel-coats. Proper surface prep is important: clean, dry, and degrease the area before applying for the best long-term adhesion.

• Bonds to fiberglass, gel-coat, aluminum, painted metal, and many plastics
• Pressure-sensitive adhesive forms a permanent bond after application
• Peel-and-apply installation; conforms to mild curves and compound surfaces

What exactly comes in the package and will I have enough characters?

The kit contains 146 decals total: four full sets of A–Z and four full sets of 0–9. That quantity allows you to register both port and starboard sides of most vessels and keep extras for replacements, alternate registrations, or future boats.

• 146 total decals: four sets of letters and numbers
• Each character is a legal 3-inch height for US requirements
• Silver fill with black outline in a forward-slanted block font for high contrast

Is this kit compliant with US Coast Guard and state registration rules?

The Series 400 meets standard U.S. Coast Guard visibility and size expectations by providing 3-inch high characters in a high-contrast style. Since some states add spacing or placement rules, confirm local registration placement guidelines before applying.

• Characters are precisely 3 inches high to satisfy common USCG and state standards
• High-contrast black outline improves readability from a distance
• Comprehensive supply reduces the need for aftermarket adjustments

Who this kit is for: The Hardline Products Series 400 registration kit is ideal for boat owners, PWC riders, marina managers, and rental operators who want a professional, long-lasting registration solution. It suits vessels with fiberglass, aluminum, painted metal, or plastic hulls and is particularly useful for anyone seeking a factory-style look without paying for custom painting. If you need a complete, ready-to-apply set that balances legal compliance with durable performance and clean aesthetics, this kit delivers.
