Hi - If it's REALLY bad and has stained things a bit there is a marine cleaner called On/Off that does a remarkable job. Be warned though, that this stuff is powerful and that while it won't damage your boat's finish, it can hurt you if you don't follow the safe handling precautions (especially ensuring adequate ventilation). This should handle any stains resulting from moss and mold as it makes fairly short work of rust stains too.
