Hardline Series 300 Boat Registration Kit – 3-Inch UV-Coated USCG Decals

Durable, Easy-Apply Registration Decals for Your Vessel

Upgrade your hull with the Hardline Products Series 300 marine registration kit. This complete DIY set replaces generic letters with a factory-style look that stays sharp in sun, salt, and spray. It’s designed to be USCG compliant and visually polished, whether you’re outfitting a high-performance PWC, a bass boat, or a luxury pontoon.

Built to endure harsh marine conditions

Printed on 4-mil thick vinyl and sealed with a UV-protective gloss, the decals resist fading, cracking, and yellowing. They’re fuel-resistant and scratch-resistant, ready for long days in the sun and fast rides across choppy water.

• 4-mil vinyl with UV gloss protection
• Fuel- and scratch-resistant surface
• Designed to resist common hull wear

Universal compatibility for a variety of hulls

Using a pressure-sensitive Super-Stick adhesive, these decals bond to most hull surfaces, including uneven fiberglass, powder-coated aluminum, and textured plastics commonly found on kayaks and canoes. This makes the set suitable for multiple vessel types and configurations.

• Adheres to uneven fiberglass and powder-coated aluminum
• Works on textured plastics and diverse hull shapes
• Includes 146 decals to cover both port and starboard sides

What’s in the box

This complete kit includes:

• 4 sets of letters A–Z
• 4 sets of numbers 0–9
• Enough decals to mark both the Port and Starboard sides

With a factory-like typography and carbon-fiber style texture, the Series 300 decals blend visual appeal with practical durability. Peel-and-stick installation is straightforward, and the kit is designed to provide a clean, professional appearance that stands up to sun and water exposure.

Real-world uses and care tips

Boats of all sizes—from PWCs to pontoons—benefit from a crisp, legible registration that holds up to sun and splash. For best results, apply to clean, dry surfaces and avoid repositioning after initial contact. Regular cleaning helps maintain the decals’ appearance.
