With modern day technology, the cruise ship companies believe they can outmaneuver mother nature, and believe that the fear created by encountering rough seas and rough weather, as well as the unpleasantness and dangers that can result, is not enough to cancel a cruise. I have written many times about cruise ship companies deciding that their mega cruise ships are capable of withstanding storms, and their reluctance to cancel cruises, resulting in passengers being endangered when cruise ships are driven into severe weather, including tropical storms and even hurricanes.
I also have also written about the Anthem of the Seas, a Royal Caribbean cruise ship, too many times this year. This includes its decision to navigate into a storm this past February. For some reason Anthem of the Seas had not learned from its mistakes, and again, the ship decided to not to cancel its itinerary despite Tropical Storm Hermine warnings.
Often times, severe weather causes dishes, plates, furniture, and other items to fly across areas on the ship, creating dangers to passengers and crew. Of course, seasickness is also common during encounters with rough weather. There is also the danger of the ship losing power during a storm, and being at the mercy of strong season winds. In extreme cases, ships have sunk during hurricanes because a ship-owner decided to take a chance and outmaneuver a storm as was in the case of El Faro.
