Hardline USA Series 350 Boat Lettering & Registration Decal Kit – 3-Inch Black

This 146-piece kit provides solid black, 3-inch characters designed for boats, PWC, and pontoons. The UV-coated vinyl resists fading, and the decals are fuel resistant with a protective finish. Best for budget-conscious buyers who need durable, US Coast Guard-compliant markings. Limitations: black-on-dark hulls may require contrasting backgrounds for visibility in low light.
Hardline USA Series 350 Registration Numbers Kit – White

This kit offers 146 white 3-inch characters, suitable for light hulls or darker backgrounds. UV-coated for sun protection and designed to resist fuel and scratches. Best for craft with white-on-color schemes or for vessels where high contrast improves visibility. Caution: ensure compliant sizing for your state’s hull markings.
Attwood 14142-7 Waterproof 148-Piece Vinyl Letter Kit

Attwood’s kit features 148 pieces with a durable, waterproof vinyl finish. The pressure-sensitive labels enable quick, clean application, and the materials meet US Coast Guard guidelines. Best for rapid, clean installs on multiple surfaces. Better for owners who want a premium feel without complex prep, but limited color options may be a constraint for highly customized designs.
Custom Vinyl Boat Numbers & Letters (Two Decals)

These decals support personalized text with multiple font, color, and size options. Sold individually, making them ideal for adding a boat name or custom branding on each side. Best for owners seeking bespoke typography rather than a standard set. Limitation: pricing may require careful quantity planning for full hull coverage.
Hardline USA Series 400 3-Inch Numerals & Letters Kit

US Coast Guard compliant and designed for durability, this kit includes multiple sets of letters and numbers in a single package, with four complete A-Z sets and four 0-9 sets. Best for boats with long hulls or for owners who require consistent, legible markings on both Port and Starboard sides. Caution: 3-inch characters may be smaller than some large vessel requirements—verify local regulations before use.
Hardline USA Series 200 Solid Black

Simple, smooth cursive black lettering with UV protection offers a traditional aesthetic. Best for classic boat designs or when a stylish script is desired. It’s fade and scratch resistant, but fewer characters per kit may necessitate more purchases for larger hulls.
Buying Guide
Key considerations when choosing vinyl lettering for boats include size, color contrast, durability, and compliance. Use these questions to compare options:
- What size characters do I need for my hull? Most kits offer 3-inch options, which meet many USCG guidelines, but check local requirements.
- Is the color appropriate for my hull color and visibility in daylight?
- How resistant are the decals to fuel exposure, saltwater, and sun exposure?
- Do I require a complete set for both sides of the hull, or just a single side?
- Is installation simple (pressure-sensitive or pre-spaced decals) or will it benefit from an application squeegee?
- Does the kit meet US Coast Guard guidelines or state-specific visibility requirements?
- What is my plan for future updates or replacements—do I need spare letters and numbers?
Durability matters: UV coatings, solvent resistance, and a robust adhesive determine how long the letters stay legible under sun, salt, and fuel exposure. For fleet or multiple-boat use, kits with bundled A-Z and 0-9 sets reduce reordering and ensure consistent typography. If legal compliance is important, prioritize USCG-compliant options that specify visibility and size. For aesthetic projects, consider font style and color contrast to match the vessel’s design while maintaining readability from a distance.
