Hardline Products USA Series 800 Boat Registration Kit –

Hardline Products Series 800 is a 146-piece boat registration decal kit that delivers durable, US Coast Guard–compliant 3-inch vinyl letters and numbers with a 3D shaded, airbrushed look.

Replace fading, flimsy stickers with a professional-grade decal system built for marine conditions. These 3-inch block-font decals are manufactured from 4-mil outdoor vinyl with a UV-protective gloss and a chemically resistant finish, giving you long-lasting legibility and an upscale painted appearance. The kit includes four full sets of A–Z and four sets of 0–9, so you can register both sides of your hull plus keep spares for repairs or future vessels.

How will these decals hold up in sun, salt, and fuel exposure?

The Series 800 decals are designed for harsh marine environments. A UV-resistant gloss helps prevent fading from sunlight, while the vinyl substrate and chemical-resistant coating repel damage from salt spray, cleaning solvents, and occasional fuel contact.

• 4-mil heavy-duty outdoor vinyl resists tearing and lifting.
• UV-protective gloss reduces sun-related color loss.
• Chemical resistance protects against fuel and cleaning solvents.
• Adhesive stays secure through wet conditions and washdowns.

Will these meet legal registration size and visibility requirements?

Yes — the kit uses a 3-inch block font designed to conform with US Coast Guard and most state boating regulations that require clear, legible registration characters. The high-contrast shading and pinstripe outline increase visibility at a distance, helping officers and other boaters read your number quickly.

• 3-inch character height meets typical USCG and state rules.
• Bold block style improves readability from the water.
• Shaded 3D finish creates contrast against hull colors.
• Includes multiple sets so both port and starboard are covered.

How easy is installation and what surfaces will they stick to?

Installation is straightforward: peel, position, and smooth for a bubble-free finish. Hardline’s Super-Stick adhesive is engineered to form a strong bond on most common hull surfaces, and the kit is sized to make aligning and applying characters simple for DIY fitment.

• Bonds to fiberglass and gel-coat without lifting.
• Adheres to aluminum, painted wood, and many plastics.
• Peel-and-apply sheets allow precise placement and alignment.
• Durable bond holds at speed and through rough water.

What aesthetic options and extras come with the kit?

The Series 800 blends a factory-painted appearance with practical durability. The beveled interior and contrasting outline create a 3D airbrushed effect that upgrades a vessel’s look while remaining functionally compliant. With four sets of letters and numbers, you also get spare characters for future reapplication or replacements.

• Beveled interior and pinstripe outline for a custom-painted look.
• Red and black color combination for high contrast on many hull colors.
• 146 total decals — four full A–Z sets plus four 0–9 sets.
• Spare characters included for repairs or multiple boats.

Who is this for? Boaters who want a legal, long-lasting registration solution that looks like custom paint will appreciate the Hardline Series 800. It's ideal for personal watercraft owners, anglers, center-console cruisers, and anyone replacing worn or temporary stickers with a more permanent, high-quality option. If you need decals that combine strong adhesion, weather resistance, and an elevated visual finish, this kit provides a complete, ready-to-apply solution for both sides of your hull.
