I would beware of taking a cruise ship with more than 1000 passengers. Or a cruise ship weighing more than 75,000 tons.
We now have cruise ships with 4000 passengers and 400 crewmembers. Some over 130,000 tons. Most of these go on cruises of 5 to 7 days.
What is the difference between a carrier and a cruise ship?
The Navy has been building larger and larger ships with longer tours of duty for the last 75 years. The Navy has a highly disciplined managerial structure and a century of experience with large groups of men and women living in very close quarters. The military has learned from experience.
The private commercial world of ships and ships’ engineers have a long experience but it's experience with large ships and large populations on the ships is less than 30 years old.
Based on the multiple disasters in the past five years on the Carnival cruise ships, it is my opinion that we do not have institutional knowledge sufficient to operate ships of this size.
Carnival Cruises have had engine failures, rampant communicable diseases of many sorts and a number of mechanical failures from a variety of causes. They even have a sinking off the coast of Italy with a totally incompetent captain and untrained passengers.
It isn't that the commercial world lacks a history of occasional disasters and a history of learning from these passenger ship problems The problem is that the rapid growth of cruise ship size over a short period of time has not resulted in the necessary institutional learning time to provide safety.
Don’t go. Don't take the chance.
