Hardline Products Boat Registration Decals Kit — 3in Marine-Grade Vinyl, Brown-Black Gradient, USCG-Compliant, 146-Piece

Hardline Products Series 200 is a 146-piece set of 3-inch marine-grade vinyl registration decals designed to give your hull a factory-style, USCG-compliant appearance while resisting sun, salt, and fuel exposure.

These registration numbers are engineered for boats that need to meet visibility and marking regulations without sacrificing looks. The Series 200 kit uses 4-mil outdoor marine vinyl, a proprietary high-gloss UV finish, and a gradient airbrush-style color that blends Brown into Black to deliver a clean, professional appearance. With four copies of every letter and number, this set supplies enough characters to mark both port and starboard sides of most vessels and to replace or reposition characters as needed.

How durable are these decals in real boating conditions?

The Series 200 decals are made for the elements common to marine use: strong sunlight, salt spray, and incidental fuel contact. The 4-mil thickness plus a UV-resistant coating help delay fading and reduce lifting or curling at edges.

• 4-mil marine-grade vinyl resists tears and abrasions.
• High-gloss UV coating reduces color fade from sunlight.
• Fuel- and salt-resistant surface protects appearance in common exposures.
• Pressure-sensitive Super-Stick adhesive resists peeling at speed.

Will these meet US Coast Guard and state registration requirements?

Yes—the characters are sized and shaped to comply with standard Coast Guard guidance for registration numbers and spacing when using 3-inch block characters. The kit provides multiple copies so you can assemble legally required sequences on both sides of the hull.

• Each character measures 3 inches to meet common regulatory minimums.
• Includes letters A–Z and numbers 0–9, four of each for flexibility.
• Total 146 decals supply both port and starboard installations plus extras.
• Instructions and installation tips help achieve proper spacing and alignment.

What surfaces and boats are the decals compatible with?

These decals bond to a wide range of marine materials including gelcoat, painted wood, aluminum, plastics, and fiberglass. The Super-Stick adhesive is designed to form a long-lasting bond on common hull finishes when applied to a clean, dry surface free of wax or oil.

• Works on fiberglass, gelcoat, painted wood, aluminum, and plastic hulls.
• Best adhesion on surfaces cleaned of wax, oil, and marine grime.
• Suitable for pontoons, center consoles, bass boats, personal watercraft, and more.
• Durable through regular hull cleaning and typical dockside exposure.

How easy is installation and what comes in the kit?

Installation is straightforward for anyone comfortable with adhesive decals—use a clean surface, align the characters, and press firmly using a squeegee or similar tool. The kit contains every character multiple times so you can spell registration numbers and maintain a matching look on both sides of the boat.

• Includes 4 of each letter A–Z and 4 of each number 0–9 (146 total decals).
• Pressure-sensitive backing for quick peel-and-stick application.
• Apply at moderate temperatures on a clean, dry surface for best results.
• Extra copies allow for repositioning or replacing damaged characters.

Who is this for: The Hardline Products Series 200 kit is aimed at boat owners who need compliant, easy-to-apply registration numbers that look factory-installed. It's a good match for recreational boaters, marina operators, rental fleets, and anyone restoring a hull's exterior who wants an OEM-style gradient finish and durable marine adhesion without custom painting.
