Salt air and sun: what they do to your boat

The two most common causes of gelcoat fade in Southern California, and how routine care slows both.

The two forces that quietly age a boat in Southern California are salt and UV. Neither is dramatic day-to-day, and both are cumulative. Understanding what they do makes it easier to choose care that actually slows them.

What salt air does

Salt draws moisture, accelerates staining at the waterline, and works into stainless, hardware, and fittings. Regular rinsing removes the daily deposit before it becomes a longer-term problem.

What UV does

UV breaks down the surface layer of gelcoat. That's what oxidation is: a chalky, faded layer where the resin has degraded. Interior vinyl, headliners, and canvas suffer the same process on a different timeline.
