Bayesian sank

Wow! Sounds like it might be a waterspout is suspected of taking it out. Waterspouts are common in FL There are hundreds per year in the FL Keys, as well as many in FL Bay. I didn't know they get any in the Mediterranean.
 
Supposedly it was knocked down by a waterspout and took on water real fast
 
The weather in Italy can get really fierce. As a matter of fact the last time I had a hard wind shear warning was on approach to Rome. We struggled on the go-around to maintain needed performance. This boat was a monstrosity with an excessively large sloop design. That is all fine, but he had it set up with lots of automatic systems to handle the rigging and sails to minimize the manpower required. There is a reason why in the old days sailing ships required substantial crew to handle them, and a sloop rigged boat of this size would require quick action with a substantial crew. Automation is just fine until the excrement hits the fan. There was a motor vessel in front of it, the Captain said he started his engine and held position just fine with the prop. If you were going to go sail on a boat this large, yawl or ketch would be better requiring less heights on the main mast.
 
Looking at AIS, they dropped anchor at 19:32 UTC and started dragging at 01:59. They dragged about 1000’ till the last position was sent 6 minutes later.

If she was knockdown by a waterspout all the large opening, sliding doors etc must have caused a massive amount of water to rush in.
 
What happens when you let Greta Thunberg design boats.
 
Overmasted may not be the right word since she had been sailing incident free for 16 years.

Some of the articles on this story arr just too much.

The BBC is quoting the editor of a sailing magazine explaining that because it was warm they must have had windows and hatches open! Typical sailor who doesn’t understand the concepts of generators and air con! No way that boat was open to catch some breeze.

 
All it takes is a few greenie weenies to make a mess of things. BTW isn't the blow over more a function of the area of the sails? They could be short on the boom.

She has been sailing in conditions which prevented an incident for 16 years. Many ocean going blow boats have a "summer mast" and a "winter mast" which is shorter to handle high winds. Indeed the ships of the line often shortened masts for rough sailing conditions. Most 18th century ships heading for the Horn often left with shortened masts. The problem with a tall mast is the period of the roll becomes longer, meaning the mast and the gunwales stays closer to the water longer. Thus any problems with the decks awash, do not go away quickly as the boat does not upright itself quickly. Instead the mast holds the boat heeled over to continue to ship water.
 
This boat and her sisterships have been around the world multiple times and faced multiple episodes of rough weather with far worst waves than was caused the sinking. At this point it all points to the keel having been retracted (as per divers reports) likely to reduce draft at anchor.

How much weight is in the keel vs the lower hull?
 
Ah-ha! The keel was retracted and it was in a heavy wind, so more mast than keel. Yep. That's Italian weather!
 
Fellows this vessel was built to American Bureau of Shipping requirements and under the supervision of A.BS. surveyors. She was built to ABS (American Bureau of Shipping) ✠A1, Yachting Service, AMS, ACCU classification society rules, and is MCA Compliant.

The intack stability of the vessel, with the Mast in place, with the keel fully retracted and fully extended has been calculated, modeled, tested and proven. Regular inspections by A.B.S. surveyors insure that no modifications are made that would affect stability and that watertight integrity and structural integrity are maintained. There is also a Stability Booklet prepared for the vessel, that details how the vessel's ballast water, potable water and fuel tanks should be loaded. It is the responsibility of the Captain and Engineer to follow the requirements of the Stability Book and make sure the tank levels are correct and the vessel, the trim is level and the draft is proper. It will be interesting see the cause/causes of this loss.

Here is the automatic iOS translation of a statement by the CEO of the group that owns Perini Navy. He is obviously defending his company but he makes some valid points.


Being italy where local prosecutors love to get their 15 minutes of fame, the captain Ian tgokgn to sleep well for next few months.

Everything that has been done reveals a very long sum of errors" - Giovanni Costantino, founder and managing director of The italian sea group, the listed company that owns the assets of Perini navi di Viareggio that built the Bayesian in 2008 - told Corrierere. "People didn't have to be in the cabins, the boat wasn't supposed to be at anchor. And then why didn't the crew know about the upcoming disruption? The passengers reported something absurd, and that is that the storm came unexpectedly, all of a sudden. It's not true. It was all predictable. I have the weather maps here in front of me. Suddenly nothing came. Ask yourself: why was no Porticello fisherman out that night? A fisherman reads the weather conditions and a ship doesn't? The disturbance was fully legible in all weather maps. You couldn't help but know."

Constantine is not indicted that sailing jewel that he calls "one of the safest boats in the world". Practically "unsinkable. Of course, unless you board water. There is no other explanation." For the CEO of The Italian sea group, the shipwreck of Palermo would certainly have represented a zero risk if the correct maneuvers had been made if situations had not intervened that compromised the stability of the ship. "The boat - he noted - was at anchor. At some point the anchor loses her grip and she moves dragged by the wind pushing her by taking her in her belly. He pushes it for four minutes that we define as a wheel and puts it in the position where it sank. In these four minutes - and I take responsibility for what I say - the ship has already taken water."

To confirm Constantine's thesis there would be the video images, where you can see the tree vertically first all on and then off, except for the bulb in the head that takes energy from a battery. If the ship went black out, it means that it would have been the water on board that caused the short circuit.

To avoid the shipwreck, the CEO continued, "it was inappropriate to have, as I read, a party. Not that evening. The hull and blanket had to be secured by closing all the doors and doors, after putting the guests in the ship's meeting point as per the emergency procedure. Then turn on the engines and pull up the anchor or unhook it automatically, put the bow in the wind and send the keel down. The next morning they would start at zero damage." He remarked that "mistakes have been made." And he added: "Between the arrival of a storm and the boarding of water there is a world. A number of activities had to be done to avoid being in that situation. I as commander of the ship would have moved, but even if for some reason I had to stay there, I would have managed those weather conditions which then, let's face it, were not so crazy. After all, the commander of Sir Robert, next door, managed to manage everything without any problems."
 
Sounds like a bigger interest in the party than in operations by the crew in a boat that was absurdly believed to be "unsinkable". A mast that tall, without a keel is begging for trouble.
 
I suspect there is going to be a finding that there is a big difference between static stability and dynamic stability.

Not phrases I am familiar with. Will have to look them up..


on edit: understand now.

Indeed. From what I read dereliction of duty. They were pulled into the party by the gang, and it led to their demise. The crew let them down. Professional? I don't think so.
