Lynn,

With all due respect, assuming your assertion that there has never been a recorded instance of someone starting a fire in their cabin by falling asleep with a lit cigarette is correct, what's the point? While your assertion may or may not be correct, there have been many verified reports of fatal fires in homes, apartments and hotel rooms caused by people falling asleep while smoking in bed. The fact that such a fire may not have occurred in a cruise ship cabin yet does not lessen the probability that it will happen in the future. Smoking in bed leads to fires. They are just as likely in a cruise ship cabin as elsewhere.

I also disagree with your comment about drunks falling overboard. The crucial difference is that a drunk falling overboard only harms himself or herself; a fire on a ship endangers the lives of everyone on the ship.
