True, but only sort of. Ablative paints are designed with carefully placed chemical decay. The surface of the paint disolves (helped by the boat's motion) and as it does, fresh surface and biocide are exposed. The point is, both ablatives and epoxies release copper at a controlled rate during the life of the paint, whether the boat is moving or not. And when the copper is gone the paint becomes ineffective, regardless of how much is left on the boat.
