These comments expose your ignorance of cruising. Why you fill your head with false preconceptions instead of experiencing the truth is beyond me.
Cruise ships are incredibly stable, even the huge tower block ships of recent years. I’ve sailed in a vast array of conditions including force 11-12 winds and large swells. There is nothing “unstable” about cruise ships. Of course they move on the waves like any ship, rolling side to side sometimes, pitching back and forth but the motion is slow and wallowing not frantic tossing about. The ships are designed and built to sail in such conditions.
This is again nonsense imo and is the kind of image you would have gotten from watching WWII movies of destroyers and submarines. It would take ages for a cruise ship to sink if it hit something and developed a hole in the hull. The ships have massive ballast tanks of water at the bottom which the captain can pump from one side to another to keep the ship level. They use these in high winds if the force of the wind from one side makes the ship list slightly.
Long before the ship came anywhere near sinking, passengers would have experienced a constant list to one side and they would have at that point gotten themselves ready for a possible exit (unless they are clueless dolts).
A recent case in point was the Costa Concordia “disaster”. I say disaster in quotes because, imo, it was a clear setup of some kind. The Concordia got too close to a coast line and hit a rock which punctured the hull.
As I mentioned above, that didn’t mean the ship immediately sank with passengers running in panic. In fact the ship (bizarrely) then changed course and sailed away out to sea for an hour with water flooding into the affected compartment below and then sailed back towards the coast again. During this odd diversion the ship began listing and it should have been obvious to passengers that something was wrong.
On the understanding that the entire event is sensitive I will state this now, no-one, but no-one needed to have died on that ship. The very moment it struck the rock and water began to flood in, the captain should have sounded the alarm, got passengers to their muster stations, lowered the tenders and life rafts and got everyone off. The entire process could have been done simply and calmly with no panic at all. Everyone would have walked away and the ship might even have been saved.
Instead, the captain sailed the ship away to sea for an hour before then turning back. A highly suspicious action which convinces me that something deliberate was going on that day but of course we will never get to the bottom of it.
The point overall is that a modern cruise ship would take ages to sink unless it was purposely torpedoed or blown up. It would start to list long before sinking and passengers would be prepped, have their life jackets on and decent clothing and be ready to take to the life boats. The SOS call would have gone out ages before the ship sank. So on balance, I have no worries on this score.
