Attwood Marine Boat Registration Letter & Number Kit, 3 in Waterproof Vinyl, Pressure-Sensitive Labels, 148 Pieces, Meets USCG Guidelines

Overview

This Attwood Marine Letter & Number Kit is a 3-inch waterproof vinyl registration kit for marking boat hull numbers with pressure-sensitive letters, numbers, and dashes. It is made for marine use where the decals need to stay readable through sun exposure, washdowns, fuel contact, and routine handling around docks and ramps.

Each kit includes 148 pieces, with four of each letter and number plus twelve dashes. The letters and numbers meet USCG guidelines, making the kit a practical choice for replacing faded registration markings or setting up a newly registered boat, tender, dinghy, jon boat, or small utility craft.

Key features

• 3-inch letters and numbers support standard boat registration marking requirements.
• Waterproof vinyl helps the markings hold up on hulls exposed to spray, rain, and washdowns.
• Pressure-sensitive backing keeps installation simple on a clean, dry, properly prepared surface.
• Resists fuel, fading, and scratches, which matters around fill areas, docks, trailer bunks, and covers.
• 148-piece kit includes enough duplicate characters for most common registration number combinations.
• Meets USCG guidelines for boat lettering and numbering.

Variants

The kit is offered in two color configurations so the registration markings can contrast with the hull color.

The color of the vinyl pieces changes between variants, while the 3-inch size, waterproof vinyl construction, pressure-sensitive application, 148-piece count, and USCG guideline compliance remain the same across the kit.

• 14142-7: Black. This option works well on light hulls where dark registration characters are easier to read from a distance.
• 14141-7: White. This option suits darker hulls where light registration characters give stronger visual contrast.

What’s included

• Four of each letter in the selected color
• Four of each number in the selected color
• Twelve dashes in the selected color
• 148 total vinyl pieces

Installation and use

Apply the decals to a smooth area of the hull where the registration numbers will remain visible and easy to inspect. Clean the surface first, remove wax, salt, fuel residue, and oxidation, then let the surface dry before placing each character. Careful spacing and a straight reference line help the finished number set look clean on the boat.

This kit is a good match for boat owners replacing worn decals before an inspection, refreshing a hull after detailing, or adding registration numbers after a new purchase. Select the color that gives clear contrast against the gelcoat or painted surface, then confirm local registration layout rules before final placement.
