The sinking of the luxury Bayesian yacht off the coast of Sicily this week resulted from an "endless chain of errors" by the crew, the ship maker's CEO is speculating.

"This episode sounds like an unbelievable story, both technically and as a fact," Giovanni Costantino — who leads The Italian Sea Group, the company that now owns Perini Navi, which built the Bayesian in 2008 — said, accord

More details not looking good for the captain:

Yacht Sank in Sicily Due to ‘Endless Chain of Errors,' Ship Maker's Owner Speculates: ‘Everything Was Predictable’

Maybe captain wanted to batten down hatches but rich owner insisted on having a party, so doors/hatches were open, people were wandering around above-decks with cocktails and crew was scattered around serving canapes not at battle stations, tornado / spout knocked the boat down, water entered too fast for crew not themselves injured to recover the situation.

Well yeah... he's alive and has a stake in the outcome, and everyone responsible is dead. He's getting ahead of the media blame game.

I guess I'm surprised a big beautiful and very expensive boat like that would be allowed to make itself unseaworthy. Pretty much job one is to not sink to the bottom. Retractable keel? Sure, but there should be some a mechanical system that fires into action if the boat tips too far.

Its like if gulfstream would let me order a g800 with windows that could be rolled down while at altitude. Some things are just a terrible idea and canapes be damned.

That was what I had been thinking too. And at about 4 am they had gone to be and had the windows open to let some fresh air in. I read somewhere that it dragged the anchor for quite some time. They should have just lost the anchor and I'm sure the boat would have managed the conditions better.

I expected to see a discussion about Bayesian Statistics. My bad.

More likely some alphabet agency.

I was actually watching that very video when I checked this forum earlier today. It amazes me that a vessel would have doors like that. A door = hole in the hull.

Why would the keel be up? The ship sank in 160 ft of water. The draft with the keel down is about 30 feet. There's no risk of touching bottom. So why raise the keel? A lower keel will result in lower rolling motion, even if at anchor. Would that increase roll frequency enough to noticeably make the boat less comfortable?

[crb07]

My understanding is the keel in the down position will bang around in the keel box while at anchor. For this reason it was common practice to leave the keel in the up position while at anchor. I would imagine the keel would make a significant amount of noise banging around in a steel box.

So a sailboat keel isn’t rigidly fixed in place? It has some lateral play?

[ramonesfreak]

Some are retractable, vertically


Also read some thoughts about the mast being 240 ft and so may have snagged the bottom, holding the boat down

Some boats will have a fixed keel, and some will have retractable keels, mostly for trailering. When I was a teenager, we had a 24 foot Venture that had a swing keel. It is my guess that the Bayesian had a retractable keel so that it could enter shallower ports? Otherwise, I don't really understand why it would have had a retractable keel.

In this video, you will see footage of a storm in New Zealand showing another large sailing yacht that is shown drastically heeling over and then rights itself back up. It had a fixed keel. There is also mention of a catamaran that was flipped over. Catamarans do not have a traditional keel like a monohull would have.

The builder of the Bayesian said the vessel was "unsinkable" because it had several water tight compartments, which is an absurd thing to say, hmmm, I can remember someone else claiming their vessel was "unsinkable" and we all know how that turned out.

If the sea wants you, it will take you. Pretty much the way it is.

[Sooner or later]

I had no idea it's mast was that tall.
