Boat owners, these Stiffie registration numbers are exactly what you need to stay compliant and look good doing it! The electric yellow color is super bright and visible against any boat color. Each character measures 3 inches tall, meeting USCG requirements when installed properly. The Whip-One font has this cool flowing brush stroke look with a forward slant that gives it some personality without being hard to read. The kit includes 4 of each letter A-Z and numbers 0-9 (146 decals total), so you have plenty to work with for multiple boats or if you make a mistake during application. The marine-grade vinyl is seriously durable - resistant to fuel spills, chemicals, fading, scratching, and curling. The UV clear coating protects against sun damage, and the lead-free inks are environmentally safe. Application is straightforward - just peel and stick with the permanent waterproof adhesive. I put mine on my personal watercraft six months ago and they still look brand new despite sun, water, and general wear. The quality is impressive compared to cheaper alternatives that fade or peel quickly. If you need registration numbers that will last season after season while still looking sharp, these Stiffie decals are definitely worth the investment!
