The Azores have a nice cool wet winter climate, perfect for growing mold.
We left the boat for about a month of the Christmas holiday and when we returned, the inside of our home was covered in a milky green hue.
This fuzzy surface was most disturbing, as it is just the equivalent of a plants flower. The real organism was living deep inside all of the wood on our boat. Our home is but a varnished and painted fungus.
