Professional hull identification that blends with your boat’s finish

The Hardline Products USA Series 350 Boat Registration Numbers Kit offers a ready-to-apply solution for compliant hull IDs in a bold 3-inch solid blue. Built to endure sun, spray, and fuel exposure, it maintains a clean, OEM-like appearance while staying highly legible from a distance.

Why choose the Series 350? This kit pairs a 4-mil outdoor marine vinyl with a UV protective gloss coating and Hardline’s pressure-sensitive Super-Stick adhesive. The result is a decal that grips fiberglass, SMC, painted surfaces, and metal with a secure, long-lasting bond that resists peeling during high speeds or after wash-downs.

What you get

  • Complete USCG-compliant set: four A–Z letter sheets and four 0–9 number sheets, plus enough material to cover both sides of most vessels.
  • 146 decals in total, all factory-matched in a solid blue to blend with OEM paint schemes.

Product features at a glance

  • COMPLETE USCG COMPLIANCE: 3-inch block letters ensure visibility on lakes, rivers, and open water across boats, pontoons, PWCs, jet skis, and tenders.
  • MARINE-GRADE DURABILITY: 4-mil vinyl with UV protection, resistant to fuel spills, saltwater, and everyday wear.
  • SUPER-STICK ADHESION: Bonds permanently to most hull surfaces, including fiberglass, plastic, gel coat, painted wood, aluminum, and metal.
  • FACTORY-MATCHED COLOR: Solid blue finish delivers a seamless, painted-on appearance rather than a sticker look.

Easy to install, easy to inspect

With a simple Peel & Apply method, you prepare the surface, align the characters, and press. The kit is designed for straightforward application by boat owners, mechanics, or marina staff.

Real-world uses

Ideal for a high-performance Waverunner, a family pontoon, or a fishing skiff. Expect legible IDs that withstand sun and splash and a clean finish that complements your vessel’s paint job.

FAQ

Q: What surfaces do the decals adhere to?
