BILLIONAIRES YACHT BAYESIAN SINKS : DESIGN QUESTIONS

[@Paul-k6w]

Saying a sunk boat is "unsinkable" might be the dumbest statement of all time. I'm surprised that an "ocean-going" sailing yacht is unable to recover from a knockdown. If it sunk that fast, something was open.

[@DavidTangye]

Forget about that issue of losing positive stability at around 80°. Just take a look at the photo at 5:00. If she were healed to 45°, roughly twice as much as you see there, imagine how much water would pour down into that aft saloon via the cutaway deck. She would ship far more water that way than she would through a few vents. That seems to be much more of a likely cause.

[@slopermarco]

That photo can be misleading if you don't consider that at the moment of the shot the wave covers the side of the ship. Nonetheless, 45 degrees of downflooding angle is a bit low.

[@labeate]

do you think the engeneers were even less than you??

[@rcajavus8141]

huge doors, unstable when keel is up. the manufacturer will get manslaughter charges as Captain did everything by the book and manufacturer is ignoring real issues and that just admision of quilt as all statements will be used in italian courts. That mast was too high demanding boat uses keel even just on anchor, the manufacturer wrote down just opposite, dont use keel when close to shore - no engineering reason to do so. Either you have mass you need to ballance or you dont need to ballance. This boat was built 2008 when crisis struck and they did stuff just to sell it - you want largest mast, sure no problem - but that mast needs calculations and operating procedures manufacturer did not confirm were safe but they gave it to captain or owner and misinformed them in fact. In italy every death is judicial investigation

[@k53847]

Constantino is making absurd assertions, like "the yacht was unsinkable", when in fact if the yacht heeled 45 degrees you'd get down flooding of engines and the lounge due to the door to the main lounge that opens as it heels and is in a scoop below the main deck.

[@janentomenkafka]

The Bayesian relates to a classical blue water sailing yacht like modern cruise ships relate to classical ocean liners. More focus on luxury and comfort, but less robust and with lower margins. That is fine as long as you stay within these margins, just like modern cruise ships avoid stormy weather. Sturdy ocean liners like the QE2 sailed on a schedule. They crossed the Atlantic regardless of the weather. And unsinkable does not exist. Closest I have seen were the sailing dinghies we used in my sea scout days... front and aft deck were airtight compartments. As long as they didn't rust through and through, the boat would stay afloat. Even if completely filled up with water or if it capsized.

[@kahhowong3417]

Long time sailor and ex yacht broker here... Dispensing with comeings seems like really bad design to me but having a cockpit area sunken below deck level is simply inviting trouble. I feel for the captain and crew who look like they are being stitched up by the Italians, who appear to be rallying around their local ship builders, who've described this yacht as unsinkable.

[@christianfournier6862]

I understand your wish for the Captain & Crew to have a fair trial, but you should'nt surmise from the start that an Italian court will not give such. We should all give our respects to the 7 persons who lost their lives, and the frenzy to draw conclusions & find culprits while the investigation is not yet complete is, in my view, disrespectful. Only thing we should conclude at this point is that the worldwide emotion provoked by this freak accident shall provoke a thorough review of both the sailboat design rules & regulations and the professional crews standard operating procedures. Sailing is thousand years old, and the sea is usually more forgiving than air: that is why airline safety R&Rs have progressed on both counts (designs & SOPs) much further than maritime safety. But, whatever the rules, there will always be danger at sea, and this freak accident is here to remind us that an Act of God is possible anytime anywhere. __ .

@@christianfournier6862 Thank you for your reply and careful consideration. If it is true that the captain and engineer have been charged so soon after the incident, it does seem to be pointing fingers even before the yacht has been raised and properly inspected. Charging those in command without any real evidence does appear to be hasty and will be at great cost to these individuals as well as to their reputations, even if found innocent. The previous captain of Bayesian has issued a statement importantly stating that the Stability Book for Bayesian quoted the downflooding angle, which is the angle at which water inundation begins, for the yacht to be a mere 40 to 45 degrees. I have delivered, sailed and owned many yachts over course of my long life, and I would not consider a yacht to be in a seaworthy state if it risked inundation at only 45 degrees of heel. To be fair it should be the yacht design that should be first investigated before aspersions are placed upon the relatively low paid crew, in the all too familiar role of "the low hanging fruit". The Italian Air force has already made a comment that the storm was unforeseen, extremely localised and unpredicted. Scant crew and a surviving female passenger have also reported being on deck one minute and in the water the next which leads me to believe that this event, which happened in the dead of night was nearly instantaneous and pushed the yacht well beyond its 44 degree downflooding limit. I have been below decks during a knockdown and can report first hand that when you upright one second and standing on the cabin top the next, and everything is upside down and falling upon you disorientation takes hold even on a very familiar and relatively small yacht compared with Bayesian. These are the reasons for my original comments.

[@r.j.martin1818]

Across all media channels, this is the first useful presentation I've heard regarding the Bayesian sinking. If, by design, a loss of stability occurs at 77°, were the crew and passengers aware, and had they trained and rehearsed for such an eventuality? It seems they certainly should have.

[@bigbono12]

The angle of vanishing stability of 88° is low on this boat because it is not a racing sailboat but rather a composite sail- motor yacht with 2 diesel engines. It is some way between a motor yacht and a racing sailboat designed for pleasure sailing and motoring.

[@allangibson8494]

The Bayesian would free flood if heeled more than 44 degrees with the lazaret closed. The lazaret wasn’t properly closed.

Minimalist keel with non deployed centerboard, heavy sliding glass ports prone to frequent closing deficiencies, a record breaking tall mast, unqualified crew and understaffing. Seems there are enough fails for a boat of this type and size. A lot of useless bling and cut corners...

[@717379]

There are toy boats that are literally unsinkable: no matter how hard you hold them under water, they always pop up. I quite understand that designing a ship is very different from designing a bath toy, but isn't it the case that you always end up compromising absolute buoyancy for function, practicality and comfort? Isn't it the case that every single element that goes on a boat has to be considered as a potential hazard to some degree? Something to keep in mind when installing heavy glass sliding doors for example? Imo, a ship should be able to stay afloat no matter what the captain does or doesn't do. But what do I know 🤷

[@Edward8855]

When a bout is at anchor and something like this happens and it is on its side, the anchor will prevent it from righting itself because there is an extra force keeping it down as well as the wind and the ballast and keel will not be able to upright the boat. Thus, the anchor could have helped to pull the boat under the water, especially in a strong wind. The ballast and the keel would have done their work if the boat was not at anker and free in the water and the working of the waves. The anchor could also have gotten entangled with the keel once the boat ended up laying on its side.

Yes...or by a rogue wave or rogue gust that knocks the spreaders into the water. I've given spreaders a bath under a bridge in mild winds, where the turbulence is unpredictable and a venturi forms between bridge piers, accelerating the wind far beyond the surrounding wind speed. In the opinion of this sailor, sailing instructor, and Marine Engineer (not a naval architect), the ship in question is not an inherently safe or seaworthy design for blue water sailing, nor is it an adequate blue water motor yacht...due to the downflooding and stability issues that you and the producer of the video describe.

[@peggypasson8794]

How can they press charges for manslaughter ? The weather was so much a factor in this .in order for it to be manslaughter they have to order a squall ? 😢

[@andrewvaughan4256]

@@peggypasson8794 My understanding is that they have opened a formal investigation and are considering whether manslaughter (or other charges) are warranted. Things like were the watertight doors and hatches closed? (And probably whether the Captain should have ordered them closed). I hope they also do a though consideration on whether the design of the yacht was flawed, and whether the relevant class rules also need tightening.

[@peterazlac1739]

Neither the captain or other crew have been charged with manslaughter only that the Prosecutor is examining the evidence for such charges. According to the previous captain of the boat it is the flooding angle that counts which is 40 to 45 degrees. This is the angle at which the engine air intake and exhaust as well as the cabin exhaust vents for the air conditioning would be under water and allow flooding of the whole vessels from which she would not recover. Apparently the air conditioning vents are simple flap valves rather than one way vents that would not accept water inlet. This seems to be a more realistic reason for the sinking than the deck openings. But the real open question is what wind conditions was the mast with its radar units designed to withstand and could h designer reasonably have expected those conditions to be exceeded, and especially the flooding angle, when the boat was anchored off shore. It is similar to the wind sheer aircraft crashes that occurred before radar was developed to detect them. This also means that the prosecutor should not be holding the inquiry but an expert body like the NSTB that has the necessary knowledge and is unbiased. A criminal probe should only follow their report if there is clear evidence of negligence.

[@elinorbullen1034]

Being anchored, her bow was possibly being held down, so making it easier for her to corkscrew over in the high wind & rough sea.

[@philg5132]

There was another ship nearby , the Sir Robert Baden Powell The captain and crew were awoken and ready to brace at 3 AM , they started the motors to stabilize their ship .They helped the survivors and saw the sinking Bayesian When bad weather is incoming is it so unusual to alert everyone onboard including passengers ?

[@annafdd]

I have to say, having been around boats since I was four or so, the interiors of the Encore are what a yacht should look like for me. The Bayesian interiors didn’t feel like luxury, they felt like dictator kitsch.

[@evanshaw17]

One cubic m³ of water weighs 2200 pounds! The huge mast the huge amount of water and upright kill and the boat sinks within 10 to 30 seconds. No one had a chance the design of the boat was an accident waiting to happen.

[@nurgle11]

easy to think of a cubic meter of water ( which is 1000 liters) weighing at 1 kg per liter i.e a ton (salt water is not the same density but close enough) 2.2lb = 1kg, 1000kg or 2200lb = 1 ton.

Why was the yacht designed with low recessed stair wells in the side decks which are sometimes under water when sailing hard?

[@theoldcurmudgeon7649]

This yacht is not designed for "sailing hard". It is designed to be a 5-star vacation toy to impress people who are not seamen.

[@allangibson8494]

The yacht would free flood when heeled 44 degrees via the air conditioning vents.

[@slopermarco]

Because this yacht is essentially a "floating resort" equipped with all the automatisms made available by the best modern technology to navigate as levelly as possible, or in any case not too heeled, as a VIP with wife, children, babysitters, butlers, guests etc. probably demands. Automatisms that work perfectly when it comes to "actively" counteracting the "laws of physics", but can do little when you are at anchor and are forced to suffer their effects "passively". 🙂

[@dianamincher6479]

A major cause for concern is the narrow stair case connecting the VIP cabins with the upper deck and freedom! It would have taken 8-12 secs to climb the narrow staircase and all the victims did not take this exit route and searched for air bubbles on the port side which was lethal. No emergency alarm was sounded and no emergency exit signage was put above the stair case as the only emergency exit from the lower deck to the upper deck! No emergency lighting was functioning either it appears!

[@lawrencehicks9607]

Some of the major design flaws in my opinion are the layout and lack of access to the owners, guests and crews sleeping areas. The only stairway access to the owners and guests sleeping areas is located on the starboard side? The crew had their own entrance to the ships galley and their sleeping area. There is a watertight bulkhead with no emergency hatch between the two areas? I think all access to the areas below waterline need to be along the centerline of the boat. Big sliding glass doors should be locked in place by hydraulic pins at sea, at anchor at night etc. A smaller watertight door on either side of the glass slider would be used during those periods. The vents for the engine room and ac units seems to be along the top of the hull? Not a good location for a sailboat. The aft area of the boat is designed like a swimming pool? It's below the surrounding desk area and has large below desk stairs which are open to the sea? Crews are small and spread thin especially on a boat this big. Was there anyway for the captain to communicate with people in different ares of the ship? Was the ship equipped with a fire alarm system? Was it used?

[@sailnattie]

One thing I have not heard any one talk about is the loss of bounce when the vessel is on here side. My guess is that she settled lower in the water when on her side. Thus aggravating the down flooding

[@triumphbobberbiker]

The captain is not being blamed by the Italian authorities...in all countries captain and crew are always the first ones to be questioned in fatal occurrences such as this. It is difficult to understand how this can prove upsetting to some... I may be wrong here, but I sense a sort of victimhood (evil Italians vs hapless kiwi captain) that is starting to emerge, and that is out of place. This is not a football match. I agree that the Italian CEO should have stayed silent (for now, at least). Yet, saying that 'the Italians' (as if they were a gang) are hell-bent on 'scapegoating' somebody is plainly wrong. Besides, UK authorities are carrying out an investigation of their own, independent of the Italian one. If UK findings will turn out to be different from the Italian ones, we will be asking why.

[@hoozleup]

If the boat was at anchor - why didn’t it just weathercock into the wind (as all other anchored vessels do)?

[@Ps119]

Built for looks rather than safety. Traditional stout design is not only safer but looks better than these modern sleek yachts that all look the same. Bayesian needed about a 10 foot wider beam, a one foot higher freeboard with no cutouts to let water in like this stupid thing, a proper heavy sailing vessel fixed keel to give a proper sailing vessel stability curve, AC and engine intakes along the centerline only and higher up so they stay well above the water even if the vessel is knocked over to a heel of 90 degrees. Windows in the superstructure that do not break due to water pressure in the event they become submerged when heeled right over. And to help occupants escape a sinking or burning vessel it needed automatic waterproof emergency lights with their own batteries to mark exit doors and hatches and paths to those exits as well as having at least 3 exits for every watertight compartment so if one exit is blocked they can still get out and get out by the shortest route - emergency escape hatches in the deck that can be popped if needed, with adjacent ladders, to allow occupants to escape up to the next deck if they got trapped. None of this is new or expensive so there is no excuse for building crappy looking vessels that stay afloat nearly all the time.

[@Gottenhimfella]

Most of all, Bayesian needed a mast height that was driven by practicality and the constraints of shallow draft, instead of the one-upmanship of an attention- seeking owner. Designers have to push back when clients and interior designers come up with foolish and incommensurable wish lists. Sliding glass doors, especially athwartships, are a death trap. Guests heard shattering glass at the time of the knockdown, and it seems to me that can only have been one of those massive automatic door panels crashing vertically down in its sliding track like a 150kg guillotine blade.

[@anjou6497]

How amazing, I will look up his story, thanks. ☺️☕

[@knowledgeandmultiskilled]

Try looking at the plumbing. A boat that size should have drainage, but it looks like it did not had any. When the boat was flooded it did not redirect any water out of the boat, and that is why it sunk, so this is a design flaw. It would make no difference if something was left opened, or closed, and no drainage should have been acknowledged by the captain, crew, and especially the Yacht builder, and designer. The pumps can only handle, so much water, and if the boat had working bilge pumps then it was overwhelmed!

[@anjou6497]

Surely it would have some kind of drainage system.

[@knowledgeandmultiskilled]

@@anjou6497 I doubt it!

[@BillyG869]

Exactly, that’s my answer. Design made it easy. But someone cold have seen that one coming. Granted they got slammed. Keel should have helped it stay flatter, but then I’m not completely knowledgeable.

[@testboga5991]

Downflooding angle may have been a bit low...

[@hugohabicht9957]

That is an understatement

[@DrJuan-ev8lu]

That is a complete understatement ! There are open canoes with better downflood angles.

[@alechiodakat9057]

Why didn't they lower the freeboard to match the inside? Seems like it would be easy? We can't get our feet wet? Mind you every yacht has a sunken lounge but the entire deck slopes away from the entrance point not inward?

[@dianamincher6479]

What's a multiple redundancies?

[@jacobdanielkuiper5744]

Can’t believe how much attention this got. Boats sink when they encounter god’s fury. RIP.

[@johnsonevans8616]

More about who owned or chartered it

[@salridulfo4065]

I am not sure where the 88 degree of righting momentum come from, looking at the diagram of stability shown here it is showing a lps of 140 degrees or more. Is the a s shown of another yacht or is it from this yacht ?

[@DavidTangye]

That is a general diagram that does not apply to this yacht

[@Dennis-vh8tz]

In an interview the -Perini- ISG CEO said Bayesian had an 88 degree angle of vanishing stability with the keel fully down, and 73 or 77 (I've seen both quoted and don't recall which is correct) degrees with the keel fully retracted.

[@k53847]

I think that is one he had on hand. I'm not sure if the former captain published the actual stability charts for the vessel, or is legally allowed to. You can be pretty sure that the builder won't be voluntarily releasing them.

[@ginog5037]

​@Dennis-vh8tz Regardless, these numbers are horrible even for a Motoring Yacht...

[@George-xb5ey]

That sail is just ridiculous

[@RumblesBettr]

Its really simple how it sank. Wet bits got into the dry bits

[@svens.5139]

Thank you Sir for this video. By the way: my personal favorite yacht is the "Borkum Riff" build by the Dutch company Royal Huisman. Kind regards from Germany.

[@liberationyachts007]

You have very good taste!

[@spacecadet35]

The yacht manufacturer is already trying to blame everyone else. They know that they will lose all of their rich customers if it can be shown to be a fault with the yacht. And it would appear, that to them money is much more important than peoples lives.

[@subpar6812]

Excessive long mast + extra tonnes of lead ballast to counter balance🤔 Defenitly will sink like a stone!

[@DavidTangye]

You have no idea what you're talking about

[@bobcornford3637]

Maybe leave it to someone that has some idea of what they're talking about.

[@The_Reckoning617]

I find it tacky and annoying that they are out there blaming the captain within 24 hours it’s extremely disrespectful to the victims and their families. There’s other access points the water could have gotten in through the A/C ducts and vents the ship was not airtight. Even if they seen the water spout coming they wouldn’t have had time to react do anything they nice quickly and it was rain wrapped meaning you can’t see it because of rain. You can’t control the weather - this seems like a freak accident.

[@jonathanarmasmcglinn1747]

Contract kills

[@Itsallwrongbutthatsallright]

Do they test the heeling angles ? Do they physically force the finished boat to heel to prove it works according to specs ? Or is it all engineer calc's and computer simulations as any heavy heel will wreck havoc on everything inside. All sailing boats should be tested IRL before handing over to owner !

[@davethewave7248]

Yep, all about design flaws, which should take into account extreme conditions.

[@paulhenry7]

It should be: BILLIONAIRE'S YACHT BAYESIAN SINKS

[@mamazalama]

I noticed that you did not speak (pronounced) the name of the boat, "Bayesian"...why or why not? It seems there is some question as to the correct pronunciation of the name, was that the issue? Is the "e" totally silent as in "Baysian" or is it spoken, as in "Bay-E-sian"?

[@margaretmatzener3752]

Why don't you watch the video of the incident...? To waste time looking for someone to blame is a no brainer.... It was a freak of nature..... The crew were busy attending down the hatches... They were swept off the deck... A down burst..!!!

[@alexhayden2303]

Surely it can be raised for less?

[@Tomm9y]

By commenting on the Bayesian, Constantino is directly acknowledging the ongoing involvement of the Peri Navi. So he, Perini Navi and the naval architect should be investigated by the police immediateley. Often builders & naval architects issue advisory changes to yachts of all sizes. It seems there are serious design flaws in Bayesian. Whatever failings of the owner, captain, crew there were, the boat should withstand severe, rapid, unexpected events. The storm was not unexpected as othe yachts had already lef the country due to the severe risks forecasted. Importantly this should also be a criteria for the UK's MCA and insurers.

[@genevepolyte8486]

This was not a manufacturer defected ship it’s the setup for it to sink by professionals…

[@GML_HRO]

Scuppers CAN NOT HELP in such a situation. Scuppers work when the water level inside is higher than outside. Here we have the opposite case: When the downflooding into the cockpit starts, the sea level outside is higher than inside. (That makes the water flow in.). The flooding stops when the level inside has reached the same height as on the outside. But as said before, the scupper would need an even higher water level inside.

[@judieg.7945]

Back ground music, the bain of many otherwise good videos.

[@carlesmiquel]

Extremely popular because extremely wealthy and influential people were on board. But science IS science. Nature IS Nature. Engineering is based on Nature. Killing the messenger never solves the question. Every yacht, small or big, owner need to understand the physics involved in sailing, understanding weather radars, deciphering Doppler signs. Even when all this is just a small part of what a Captain knows, Nature vs not perfect (we have a 10B spacecraft stuck because of some engineering issues) engineering will always win. And since engineering will never be perfect, Nature will win over us many times. It’s sad to put the entire guilt of this on a human being, especially after knowing how extremely rare are huge downdrafts falling exactly on the tallest mast ever built on a boat at mooring, so, logically, without the stabilising effect of the blades. The key here is who’s going to lose the most money. Sad.

[@ginog5037]

Many unanswered questions from the boat design, crew, weather, to foul play. Hopefully, the truth will come out soon and verified by many experts...

[@edwinodus]

It seem this mast gets knocked over often

[@sniper10666]

My question is why have a yacht that anyway what’s the point .

[@DrJuan-ev8lu]

Is there any way to save a boat that gets knocked down near horizontal which is past self righting recovery angle and way way past the designed down-flood angle? This ship is a founder waiting to happen ... The Shamwow of the sea!

[@k53847]

The various ventilation systems can be made to automatically seal and you can avoid installing water tight doors that prioritized looking cool over the whole water-tight bit. But basically, past that point you need some outside agency to save you before you slowly sink. Or you need a method to sever the absurd mast and get the vessel upright.

[@skippco8930]

a captain is responsible for his/her ship. no excuses. weather was predicted. buck stops with james cutfield.
