Hardline Products 3-Inch Boat Registration Numbers Kit - Silver with Black Outline, USCG-Compliant, UV & Fuel Resistant

Hardline Products Series 700 is a complete 3-inch marine vinyl registration decal kit — silver bodies with black outlines — built to meet USCG and state requirements while resisting UV, fuel, and abrasion.

When you need registration numbers that look professional and stay put in harsh maritime conditions, the Series 700 kit supplies everything required for both sides of your hull. These ready-to-apply decals are made from thick marine vinyl with a high-contrast design that satisfies visibility rules and gives boats a clean, factory-quality finish.

How durable are these decals in real boating conditions?

The Series 700 decals are constructed from 4-mil marine-grade vinyl and printed with lead-free inks, then finished with a UV glossy coating. That combination reduces fading from sunlight, withstands occasional fuel splashes, and tolerates light abrasions from docking.

• 4-mil outdoor marine vinyl for long wear
• UV glossy topcoat to limit sun fade
• Resistant to fuel and light scuffing
• Printed with 100% lead-free inks

Will these stick to my hull material?

Yes — Hardline’s Super-Stick adhesive is formulated to adhere strongly to common marine substrates. It bonds to fiberglass gel-coat, painted aluminum and powdercoat, plastics used on PWCs and kayaks, and typical wood finishes without lifting at speed.

• Designed for gel-coat, aluminum, plastic, and wood
• Adheres under high-speed and wet conditions
• Applies smoothly to contoured or flat surfaces
• Best results when surface is cleaned before application

What does the kit include and how many characters can I make?

The package contains 146 individual decals: four complete sets of A–Z plus four sets of 0–9, providing enough characters to register both port and starboard sides with extras. Characters use a 3-inch block font with a black outline to meet USCG contrast requirements.

• 4 sets A–Z and 4 sets 0–9 (total 146 decals)
• 3-inch block numbers and letters with black outline
• Enough extras for multiple boats or replacements
• DIY-friendly application: peel, align, press

How do I install the numbers so they look factory-finished?

Preparation is the key. Clean the area of wax, oil, and grime, lay out characters to check spacing, then peel and press each decal firmly to eliminate bubbles for a professional result.

• Clean surface with solvent-free cleaner
• Dry and position characters before sticking
• Press from center outward to avoid air pockets
• Allow adhesive to set before heavy use

Who is this for: The Hardline Products Series 700 kit suits boat owners who demand compliant, long-lasting registration decals that look factory-applied. It’s ideal for owners of center consoles, pontoons, bass boats, personal watercraft, kayaks, and aluminum fishing boats who want a durable, high-contrast identification solution that endures sun, water, and dock wear.
