What's the metacentric height on one of those?
Now there's a blast from the past.
Next you'll mention "Lost in the hurntgen forest", or more recently "TLBshow".
The largest ship I have captained is a 32 footer cabin cruiser. With it's twin turbo diesels and twin stainless steel shafts and props, I could give her full speed full port and it still was slow to turn. Radical abrupt turns can happen in speed and sport boats, but not on cruise ships of this size.
So no, it didn't happen in the manner offered.

Perhaps, but something sent 92 people to the hospital.
Think it's possible that a control system failure made the rudder go hard over?

Hope so, but everything worked fine all way back to port and they can find no problems now.
The possible cause being bandied about is similar to 'Uncoordinated Turns' which happen in an aircraft when the rudder and ailerons are turned in 'opposing directions' for lack of a better term. they think the thrusters/stabilizers and rudders moved in opposite turn directions.
That's what I would have guessed.
Obviously SOMETHING serious happened, if the ship turned on a dime, all the water in the swimming pools slopped out, and that many people were thrown around and badly hurt. Either sabotage or an accident.
Or an uncharted shoal or incompetent navigator, maybe, if they were approaching the Bahamas.
11 miles off FL coast.
Deep water, then.
I don't claim the slighest expertise on that. The cruise line is blaming it on a massive steering failure, so maybe something made the rudders, thrusters, and everything else suddenly kick in.
The idea that it was a terrorist attack blows my mind, but everything since 9/11, including a smidgeon of coffee creamer on the counter in the coffee bar at the office, has been attributed to terrorists, at least temporarily.
The WESH story is good, but read between lines. In this case was no commanded turn. Why did ship turn / list as it did in this case?
Yes.
Even in rudder hard over it would still take several football fields to turn.
These ships have redundent steering systems. For a rudder to go hard over like that, a steering rod would have to snap, or the rudder post would have to fail. I investigated a 36 inch rudder post failure on a super tanker once. But, on a new vessel, I don't think that was the issue. These vessels have gyro-stablizers, stabilizer fins, and I believe quick ballast water movement to provide passengers with a puke free enviornment. My best guess at this point is that the stabilizers may have malfunctioned, not the steering system.
That's interesting, I'd like to read it when it done. plz ping me.
Interesting theory.
Perhaps a whale was surfacing under the ship and nearly knocked it over. (My own fanciful take--for entertainment purposes, only.)
It's a mystery, for sure.
I think the folks who insure these ships would agree with you... Also, almost the same thing happened a few months ago when a family member and friends went on a cruise out of the same port. The ship engines stopped and the ship listed wildly to one side. Up until that time, no one in that group had ever heard of such a thing...
