And that is why I only drink bottled water or alcohol on a ship.
I cruise on my own boat but.......we have a 100 gallon water tank on board that literally doesn’t get used for anything except washing dishes. First thing I always tell everyone is.......don’t drink the water, there is plenty of bottled water and beer. ;)
We add the water additive that supposedly keeps it drinkable but I just don’t trust it. It sits too long.
I tried that one cruise. I just threw out the water. Worked like a charm! I don’t remember getting sick, but then, I don’t remember the cruise. :^)
