What is the green build-up on my boat cover?

  • green build-up are algae and moss.
  • Algae and moss are organisms.
  • These organisms grow easily on a wet, moist and shady surface.
  • Take a good look at your boat cover. One side is probably greener than the other.
  • That green side, with lots of algae and moss, probably gets less sunlight.
  • Less sunlight means that the fabric stays moist longer there.
  • That is also the reason that this annoying green build-up mainly occurs in the fall, winter and early spring. After all, these are the months with the least sunlight.
