56M Perini S/Y Bayesian Sinks During Palermo Storm

Niii which means a yes or a no.

The stability issue becomes as much a problem for Bayesian as it is for the Class.

Because at the end of the day this is a classed yacht, certified by ABS.
That stability booklet is certified by ABS (American Bureau of Shipping) to a yacht ✠A1, Yachting Service, AMS, ACCU classification society rules, and is MCA Compliant for charter.
If the class would have not been happy with the booklet Perini Navi as probably any other yacht builder would have complied.
You cannot sell a 50 meter yacht if not build up to class, or it very hard.

As for the captain probably his only fault is that he probably under estimated the Med Thunder Storms when seas are around 30 degrees.

You can try as much blame the builder as much how you want, but really the Class is much as fault as much as them.

I know I heard a report, "wake me at 20 knots", and the time line seemed to require a few extra minutes beyond 20 knots, to 30 knots, prior to awakening. That aside, no discussion of weather equipment monitoring? If the vessel is underway, and the captain sees the weather that the mate was filming for social media, he'd be on the gear looking into the details of what was headed in his direction.

The stability booklet is certainly troubling. Was it not updated to speak to the terms of the new, taller mast? That mast is a hell of a sail...and it seems to me that I have a standing order to lower the keel if the wind reached 20...

It's a bad accident. I don't see anything that screams manslaughter, to me. But I do see room for improvement. I think...

Was the boat even in deep enough water to drop a 10 meter board? Remember she dragged quite a ways from where she was anchored. That a sail boat couldn't recover from a knock down with out sinking is another thing.

Stability is approved by flag state.

I m pretty sure they be already established the big shell door was closed and that the flooding was caused by inadequate stability thru the vents

I would also put my money on that if I should bet, but how can you be so sure, Pascal?

I mean, surely the investigators already know more - possibly MUCH more - than what has been disclosed so far, also because I would expect the salvage divers to have photographed/filmed extensively the wreck, before touching anything.
But aside from all the speculations internet is flooded with, I've yet to see any official report on their findings.

A few months ago there was some underwater video of the garage and engineer quarter which showed a closed external door.

IDK is the short answer.
I guess they aren't considering the matter urgent because, as opposed to planes falling from the sky, the risk to kill hundreds of people in another identical boat doesn't exist, since there's none.
