What affects decal lifespan
Sun exposure, saltwater, temperature swings, and how often the boat is cleaned all affect how long a decal lasts. Boats kept in covered storage last longer than those left in direct sun year-round.

How long do marine vinyl decals last?
High-quality marine-grade cast vinyl decals typically last 5 to 7 years in outdoor marine conditions. UV exposure, saltwater, and maintenance affect the actual lifespan.
UV stability matters
Marine-grade cast vinyl uses UV inhibitors that resist fading and cracking. Cheaper calendared vinyl may last only 1–3 years in the same conditions.
Maintenance tips
Wash decals regularly with mild soap and water. Avoid harsh solvents, abrasive pads, and high-pressure washers held close to the edge. Wax over the decal to protect it from UV.
When to replace
Replace decals when they crack, peel, fade badly, or no longer contrast with the hull. Faded numbers can make a boat fail inspection.

Does saltwater shorten decal life?
Yes, saltwater can accelerate wear at the edges. Rinse decals with fresh water after exposure to extend their life.
Can I wax over vinyl decals?
