>Big ships like this one can't make radical abrupt turns.
But this one did, didn't it? (see MSM reports, please)
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.
