What affects lifespan
UV exposure is the biggest factor, followed by saltwater, temperature swings, and abrasive cleaning. A boat kept covered or in a slip house holds its decals far longer than one that sits uncovered year round.

How long do marine vinyl decals last?
Our decals are cut from Oracal 651, which carries a six-year rated outdoor life. Real-world lifespan depends on sun exposure, saltwater, and how the boat is cleaned and stored.

The material we use
Oracal 651 is a durable outdoor calendared vinyl with a six-year rated outdoor life — the standard material for registration numbers. It stays flexible on a hull and releases cleanly at replacement time.
Maintenance
Wash with mild soap and water, rinse salt off after every trip, and keep abrasive pads and close-range pressure washing away from the decal edges. A coat of marine wax over the decal helps with UV.
When to replace
Replace when characters crack, curl at an edge, or fade until they no longer contrast with the hull. A faded number is a legibility problem, and legibility is what the law actually requires.
Related questions
Does saltwater shorten decal life?
It accelerates edge wear. Rinsing with fresh water after use meaningfully extends life.
Can I wax over vinyl decals?
Yes. Marine wax adds UV protection and makes cleaning easier.
Will the color fade evenly?
Usually gradual, though sun-facing areas fade first. Check the starboard set if the boat is always moored the same way.
