at 105,000 displaced tons, traveling at 20 knots, it would snap with a thunderous explosion, dent up the outer hull a bit and ensure that the continual endless evolution of painting the ship is safe.
The Navy? Yeah you’d be looking for another line of work...
You are comparing a Battleship, with armor - against a cruise ship. Do you honestly think this is a fair comparison?
Here’s a hint ... the cruiseliners are not designed to go into battle. They are not designed to take this kind of stress.
That’s why they don’t land aircaft on them, or have gun mounts on them.
>> it would snap...
Yes, unlikely a anchor assembly would be designed to sink the ship is supposed to simply tether. No doubt there would be some significant dredging before that “thunderous” snap.
Maybe on a Battleship. You want data, let's throw some math at this.
Kinetic Energy = 1/2 (mass) x (speed)^2.
Look it up.
70,000 tons = 63 502 931.8 Kg 20 knots = 10.288 Meters/sec The energy that would be expended at a absolute stop would be
0.5 x (63,500,000) x (10)^2 Joules
~3.175 Billion Joules. That is a lot of energy to dissipate.
Now we both know that the ocean floor will likely not grab the anchor and stop it and snap the chain ... it will dissipate this energy, or some percentage of this energy over time. But, the energy will be dissipated in stopping the ship quickly, possibly permanently damaging the structural integrity of the ship, certainly impacting the passengers (who are travelling at 20 knots with the ship) who will be propelled forward without warning, into God only knows what fate. As for the shear point of the anchor chain - assuming that the shear point is reached - there will be a horrible explosion if that happens - assuming the shear point is reached. Personally, I doubt the chain will break, I do expect the ship will face extensive structural repairs - if the damage isn't to the extent that the ship can be repaired vs 'totaled' and condemned.
Meanwhile the cruise line has either extensive repairs, or a lost ship; certainly lots of unhappy vactioners who planned their vacation monthes or years out, an unknown number of
