56M Perini S/Y Bayesian Sinks During Palermo Storm

Well in that case, delivered from the yard with a built-in stability problem, ouch..

As for the night of the accident: She was dragging anchor and therefor never got the bow into the wind, now she is constantly subject to strong downdrafts with gusts @ hurricane strength from the side, that and the centerboard being retracted, worst case scenario.
Interesting if the anchor and chain will be retrieved and looked at, possible damage/deformation may yield clues as to the wind strength and/or weaknesses in the ground tackle/chain.
What is the sea bottom in the area, sand, mud, grass, rocks?

Another large sailboat tried to ride out a hurricane for anchor in the Florida Keys, not only did she drag but I seem to remember the anchor came apart and was rendered useless (?)
We had a long thread on that fiasco right here on YF, time to go digging.

Found the thread on Perini Navi SY Legacy, she dragged anchor in Hurricane Wilma and got beaten up pretty bad.

In reverse order:

Investigation is a legal requirement in Italian law, in an accident like this. You may not like that, but a whim of the moment it was not, by any stretch of imagination.
Regardless, I would call outrageous not investigating at all. How would you like police not making an alcohol test to a driver involved in an accident where some relatives of yours were killed?

Ref. US justice, I suppose you actually meant digress rather than distress, because the latter gives a weird meaning to your sentence.
Anyhow, if you think integrity of US justice is being restored, that's your opinion, and as such respectable.
But FWIW, anyone involved with the US that I occasionally speak with (both around EU and in the US) think exactly the opposite, i.e. that it's going from bad to worse.
Just other opinions obviously - but less biased than yours, I reckon.

Last but not least, ref. Senna, blaming the prosecution length instead of the Williams attitude to hide and/or destroy all evidence of the true accident reason (eventually proved beyond any reasonable doubt) is sort of funny.
If it weren't tragic, that is.

Not sure of what your distinction between a "plain" investigation and a criminal investigation means, but according to our law whenever there are casualties (or even just injuries) involved in an accident, the legally required investigation is classified as criminal no matter what.
If to you that smells of a coverup, again, that's your opinion.
But one thing I'm sure of is that the LACK of a criminal investigation would have smelled of negligence - to the point that the competent authorities could have been charged of that, if they wouldn't have started it.

Ref. US politics, far from be willing to dig deeper, also because I'm well aware that it's a topic that Carl doesn't fancy seeing discussed on the forum.
But as I said, I was actually referring to personal contacts with persons directly involved with (and some of them actually citizens of) the US.
Anyhow, if European media coverage of US politics makes you laugh, well, I could argue that to many people it's the actual US politics that is laughable, not its media coverage...
