45 degree downflooding angle on a sailing yacht. Unbelievable. No wonder the design firm is trying so hard to deflect blame. Any staircase should be as close to centerline as possible. Any large sliding doors should have a centerline normal width door section, and the locking mechanism for the large doors should be strong and easily closed even with power off conditions.

[@chrisk1732]

Downflooding :- ( Angle ) ThisYacht …. Keel UP # 40, dg *Angle Keel fully DOWN # 90 o dg * Angle Very LOW for this length / size of yacht !,, ???

[@justadam1917]

Compounded by the fact at 70° it was beyond self righting so just fell over

[@eleanorjames1118]

Just a point. When the yacht was actually heeling under sail, the vents could be closed off and so the downflooding angle wouldn't be an issue. Of course, being at anchor, with generators and aircon running, all tbe vents would have been open.

[@jpdj2715]

From eSysman's (referenced in this video too) analysis and shared (public) video footage, I get the impression that sliding doors and doors to engine space were closed shut. What seemed already open when the divers went in, were the hatches over the stairs to the crew layer in the bottom of the boat. Suggests human error. If the keel was still up, then that was a human error. If these hatches were still open then that was a human error. Part of the crew may have been shifting furniture on the owner/guest floor in order to free escape hatches in those floors - and such furniture having been placed there in the first place was human error. And safety/rescue procedures probably never got rehearsed because, imagine, owner and guests would have to look crew in the eyes or take orders from them. Human error. Yes, it was "sinkable". With the keel up that was very easy. The boat is just too small relative to what can happen on the oceans. More or less random "super waves" happen out there - at the deepest physics level not random at all, we just aren't able to predict them in reality with current computer models because we don't have all the data needed all the time. And this does not include tsunamis.

Thank you for the post. I am italian and our daughter was on their boat, that night, a few miles away from the Bayesian, getting ready to partecipate to the Palermo Montecarlo sail race. Thay had no issues that night, but we followed the whole event quite closely, of course. You showed professionalism and competence in commenting the available material, great video.

They need to name a vessel "The Most Sinkable". Then there will be a story 300 years from now... "The ship known as 'The Most Sinkable' has survived 37 collisions, 22 undiscovered WW2 sea mines, 26 hurricanes, 17 rogue waves, and 4 groundings. Thankfully, no passengers have ever been injured. We expect this ship to be decommissioned in about 100 years."

@@SSPDIVING Fantastic information. So much great technology, so much courage involved in using it. As for the "Bayesian", those flooding and righting angles are insane. For such a tall sloop rig, how can a knockdown be let go as inevitably fatal? Glad you mentioned the Contessa 32, a legendary tough boat, but time is passing and people forget.

[@Yachtwhisperer]

Thank you for posting the video. One of the most disappointing things I saw after the unfortunate incident, was that Mr Costantino, the president of the Italian Sea Group was assigning blame prior to the results of a proper investigation. Let’s start with the fact that when the yacht was built, Italian sea group didn’t own the Perini Navi yard nor they had anything to do with the build. The Perini Navi brand was acquired in December 2021 from a bankruptcy court. So they had nothing to do with the build, design or engineering of the ship. Furthermore, to say that a yacht is “Unsinkable “, has been historically proven to be the epitome of arrogance. I do hope that the truth comes out after a proper investigation and that we all learn from this unfortunate incident.

[@michellefields2115]

Totally agree I think what this company did is very sleepy if I had the money to buy a yaht I would not buy one from them!!

[@sailorlac]

Rather than a waterspout which sucks water up, it's more likely now that to have been a downburst, which does the opposite. There are intrinsic flaws in design, namely the two outdoor lounging areas, one forward of the mast, the other aft, both "sunken" with limited ability to drain the water out in a weather event like this which was accompanied by 100 kts of wind, and yeah, that mast was way too big. And BTW water capacity in the tanks is not so important as the yacht would have been equipped with water makers. Another issue is the lack of handrails on both the stairways, companionways, and in the wider open spaces like in the main saloon.This possibly could have aided in the survival of passengers if, which sadly they did not, had made it out of their cabins. Bayesian was, officially on paper, considered to only be a sailing yacht when under sail, a motoryacht the rest of the time. Great video, adding new expertise to the investigation, great complement to The Yacht Report. Did you know Brett Gilliam (RIP), he was pioneer in deep diving.

[@juliettedonohue7069]

100 kts wind on a ship which is dragging its anchor and is no longer facing the wind will keel more than 50 degrees.

Lots of excellent information. I know very little about diving, but from a lay perspective, it seems unbelievable to me that being "only" 164 feet below the surface requires huge protocols for divers to operate safely at that depth. Water is heavy, but for many of us (or at least me) who spend their whole life above water, it is hard to appreciate what a huge effect the weight of water has on the human body. It also gives new perspective to how stupid the Ocean Gate dive to the Titanic was. My hat is off to you and the other people do this hugely important and dangerous diving work. All the best.

[@hillbilly4christ638]

I was certified in 1985. That was taught back then. When you dive, you can feel the effects of depth. Initially you have a comforting feeling, then relaxation and if you go deep enough inebriation. As a young diver I was on a group dive and some of the group descended to max depth and then ascended after five minutes. They did it for the thrill and the feeling they got. I recognized it as recklessness and was dangerous. The dive master could have put a stop to it, but refused to say anything. I had unique first hand knowledge of some accidents that took place and in one event this type of recklessness claimed the lives of four divers and only one survived. Diving can be very satisfying, but it always carries an element of danger in open water. Never ever underestimate that danger or be so confident that you overestimate your ability.

[@flybywire5866]

There are many unsinkable ships on the ocean floor that you can buy for free. I think it's strange that the ship's designer, or was it the yard who built it, knew exactly who was at fault, just not them, even before it had fully settled on the seafloor. I wonder why it was so urgent to make that statement. Calling a vessel, supposedly in perfect condition, that sank within 60 seconds unsinkable is hilarious.

Everyone with eyes and ears could see a big storm coming, they sailed there to protect themselves from the storm.

@@helenorgarycrevonis2022 There are a few coincidences and rare events at play and it makes sense to ask "what if" and wonder if something nefarious happened. The danger is that of confirmation bias: a person chooses to believe in a theory (say he was murdered by spies), then looks at every piece of information that might align with that foregone conclusion, while ignoring and dismissing evidence of the contrary. The better way is to prove competing theories wrong and then look at what is left. Some people might want to dismiss the theory that a microburst could have knocked the yacht on its side beyond angle of vanishing stability. Others might want to prove that with the various doors, even on its side the vessel would have floated. Or people might check how quickly would a sleeping person escape the vessel when water is flooding etc. A person might also look at how complex is to stealthy attach a line to the top of the mast, then tug it unobserved with some submarine? to overcome yacht righting moment, maybe infiltrate an operative aboard to ensure the keel was retracted, certain doors were open and orchestrate crew to be on deck to handle furniture. Bottom line, be wary what you pay anyone who sells you their theories. Unfortunately for us, we don't have the data/information to know, so it will always boil down to give credence to some experts. I personally believe it was a black swan weather event that pushed the vessel beyond its design limits. It is unfortunate that all passengers below deck were trapped and lost their lives. But I confess I go with Occam Razor here. I think a conspiracy would be too complicated - but not impossible.

Many subway cars have a problem with the sliding connecting doors, at each end of the car, opening and slamming closed as people pass through while the train is rocking. The problem was solved pre-WW2 by using an automatic gravity latch at the top of each door. Once it slides closed, it stays closed. But simply twisting the door handle unlocks it as you open the sliding door. The same latches would have kept the sliding doors on the Bayesian closed. If the designer thinks the problem is unsolvable, he's at least 75 years behind the times. He screwed up big time if those doors couldn't be kept under control.

The builders/designers are doing thier best to blame the crew. Wrong. The crew were not at fault. The blame is clearly in the design of this vessel. This is a very large company that is trying to shove the blame on the crew. I have followed this from day one. I am a professional diver also and a master captain of a 300 passenger ferry. I have “been around the block”.

I have never been diving. What happens if you have to sneeze or does that not happen when your underwater breathing from a regulator?

[@SSPDIVING]

You know what that’s a great question! When we exhale say through a scuba regulator for example all of our air we exhale leaves the regulator through the exhaust on the sides of the regulator… same principle applies if we sneeze. I think it’s a natural reaction to put one hand on my mask to make sure it doesn’t slip off my face lol To be honest it doesn’t happen often. 1) we have filtered air probably cleaner than the air both you and I are breathing as I’m writing this. So breathing in anything you’re allergic to is pretty much eliminated. 2) if on scuba, you will be mouth breathing anyways so not much to irritate your nose. Only things we have to be cautious of is diving with a stuffy nose, etc. as it can cause blockages and sinus squeezes which hurt like a mofo. I’ve only had one that was bad early in my career, that was enough for me to pass on diving with a cold from there on out lol

The so called "Comando raggruppamento subacquei e incursori «Teseo Tesei»" also known for short as Comsubin, it's an elite battalion part of the italian Navy and it's subdivided in two groups: the first one called Gos (Subaqueous operative group) and it's most likely the one that intervened in this instance.

[@3613jeremy]

I cant remember where i seen it or if it was even considered hot tapping but it seemed identical with the exception of them using some kinda suction cup system to lock the valve down to to the hull of the ship but i definitely enjoyed hearing a professional point of view

[@SSPDIVING]

You know what, that’s a great point. I haven’t seen a suction cup system but I’ve used suction cups underwater before. They would probably work well on this smooth aluminum hull.

Well Done, Thank You. LEFT and PORT are four letters.

[@Paul-k6w]

@@SSPDIVING Several things about this boat are "misleading". This really isn't a sailboat. It has two engines and the above-water surface area of a motor yacht. It is a motor-sailboat. Even the smallest of sailboats can point into the wind and survive just about anything. I suspect the inability of this motor-sailboat to point into the wind caused many problems. The retracting keel can help with stability, but its primary use is in upwind sailing. The aluminum mast was a big mistake. Aluminum is too heavy and carbon fiber should have been used. Putting the biggest aluminum mast on a motor sailor is just looking for trouble.

[@StefanMochnacki]

In elementary school, we were taught, "I left Port".

[@flowsnake8732]

Yes port is a shorter word than starboard, left is shorter than right, and red is also shorter than green. And "there's a bit of RED PORT LEFT in the bottle" (if you're lucky) ;)

[@Hhllbb2476]

L is next to P, R is next to S but the red port in the bottle is good. Red like port is short, green like starboard is long.

[@jfmezei]

Was sent here by eSysman. s PADI just Advanced, I really appreciated the Nitrox/Heliox explanations. Portions of the footage was on the bridge, portions in the engine control room, I think you use "control room" for both. They would not have gone from engine control room up to bridge, they would have gone back out and then swam outside ship up to bridge (otherwise their cables wou;d have to be strung through all the complex corridors/stairs/doorways up to bridge) and they wouldn't be able to escape from bridge. Leaked videos always removes context and valuable information, it is just clickbait. It is like NTSB preliminatry reports that provide pictures of incident that were carefully chosen to prevent people making conclusions. Yet, you were able to extract plemty of info from it and thanks for taking the time to explain. On the salvage, MUST they epmty the fuel tanks? What if they infated a couple of balloons attached to the end of the mast, could this provide enough leverage to right the ship, at which point they could inspect the starboard side hull and if there is no damage, could raise it without needing to empty the fuel tanks? In a salvage operation would they try to replace the fuel with air to make ship less negatively bouyant? (I guess they would need to keep the valv open somwhere to prevent tank from overpressure as it rises if filled with air). Watertight doors are of use when there is a breach in the hull. But when the water comes from above, there is 0 protection.

[@gdmonks1959]

The fuel is way more buoyant than the water that surrounds it, oil floats on water! The reason for removal is mainly to prevent spillage and thus prevent pollution. Depending on the location of the ships fuel tanks can affect stability but I imagine they are low in the bottom areas of the hull

[@edmundwest5636]

Are stability calculations made with or without weight of furniture / fittings.

[@NiteCourt]

"LEAKED" footage! Makes sense!

[@SSPDIVING]

Lmao My kind of humor 😂

[@thedolphin5428]

Why not just lift the top of the presently horizontal mast to vertical to at least get the hull upright. Then, surely, bringing the hull upwards to a more manageable dive depth would be greatly advantageous.

[@SSPDIVING]

To do that I would imagine they would need to rig directly to the mast, probably 50’ or so from the top of the mast since it will be sticking out if the water if stood vertical. The rigging location on the mast would need enough strength to secure rigging to. (Either a crane from the barge or flotation, which it would take a lot of) With smaller pleasure crafts we have rigged lift bags to the top of the vessel or the fly bridge in order to right the vessel first. After that we’ll rig belly straps under the hull OR lift bags below the gunnel. Once it’s at the surface, pump out the water and let it float OR pick it up and set it on a barge. Anyways… I don’t even know how to calculate for this vessel but in short, the rigging needed may be too much work than sliding some belly straps under the vessel and lifting with a crane. It will in theory right itself, they may rig something to the mast, or may cut it all together. Not sure but I’m excited to see how the salvage unfolds. I will provide updates when it happens. Cheers.

[@hughajk]

Well done. Am just a PADI AOW but have been down to 55M while qualifying but only know a little of the world of commercial diving through reading. Yes, I was immediately struck by the bottom time being so short for the initial divers and was interested in your comments about gas types/mixes as a professional diver. Wreck penetration with all the gear must have been hard and even more so with the lines to keep clear. I too wondered about having the tender inside the wreck although it does happen with cave diving, but they tend to stick with SCUBA rather than using an air umbilical. As for your comments about the quality of first video, it was done just after the storm so wouldn't the sediment have been stirred up, even at that depth?

[@lyfandeth]

55 meters is 180 feet. The normal limit for recreational diving is 130 feet, so 180 becomes a risky bounce dive. The Italians "had to" dive on surface air, simply because working for prolonged times at that depth requires long decompression times. And that means lots of bottles and swaps, or surface air. I assume they were diving on air, not mixed gasses. First, because that's the surface air supply. Second, you can see the twin tanks have no color code for mixed gas. I think Italy follows the international convention of using large black and white segments on the tanks to mark that. Unmarked tanks are air--same as the US. PADI used the standard USN tables for many years. I raised that point with a USN Chief Diving Medical Officer, and he confirmed that is WRONG. "If you need a wetsuit, you need to use the COLD WATER TABLES." Which basically bump you up and back 2 steps in the NDT tables. Again, making 55 meters a risky bounce dive. PADI may have their own custom tables now?

[@vincentchevallier9177]

AOWD at 55 m??? You are a idiot and so is your instructor!!!!!..

[@jo.s7993]

@hughajk When I was a PADI Divemaster in the nineties, we used Canadian dive tables, because they were the most conservative. Thirty meters was the recreational limit at that time, but we were dry suit diving off the Cornish Coast of the UK I.e. the North Atlantic, so cold water. Maybe things have changed in the twenty - five plus years, but I'm surprised that your instructors were happy with you diving to fifty-five meters, as an advanced open water diver on air.

FYI Teseo Tesei (3 January 1909 - 26 July 1941) was an Italian naval officer, who invented the human torpedo (called Maiale, Italian for "pig") used by the Regia Marina during World War II.. in the italian (marine) corps it is quite standard to name a team with a former (military) hero the dives were supposingly done with trimix and in case I expect, at least on the most experienced or specialized units, with rebreathers I think the most already know that these provide mixture ratio optimization with the onboard computer Apart of leaked videos I would assume the most of things, facts and information as well as emplyed persons and equipment is not disclosed

[@brianperry843]

Given the Special Forces divers total dive time I would think dry suits would be used for thermal comfort. Was that what you were referring to regarding the hose for the diver’s buoyancy? Without that hose connection the diver would experience quite a suit squeeze.

[@SSPDIVING]

Sorry, I was referring to their BCD. Buoyancy compensation device. The vest they wear with the tank strapped to it. From what I can tell August & September water temps would still be close to 80 degrees F. Even now in October it appears to be 70F. So wetsuits are totally doable. Idk what thickness they are wearing so we have to make an educated guess but we can dive 50F for 1-2 hours no problem with 7mm wetsuits.

[@patrickchase5614]

wrt the tender entering the wreck, is it possible that there's a third diver acting as an additional tender outside of the wreck, or is that simply not done? If a penetration dive is particularly complex such that the umbilical needs tending at multiple points, could/would they send additional divers down?

[@SSPDIVING]

Oh it’s 100% possible. I sort of touched on that when reviewing the baby’s procedures for wreck diving. In fact the navy requires an additional in water tender for each level a diver penetrates they would also require one if the dive plan included two divers entering the wreck, The thing is, logistically I highly doubt they planned on that as they would need three divers plus an additional standby diver topside in case of an emergency. I speculate that diver 1 was having difficulty with the door and they allowed diver 2 to help considering the limited bottom times. This is of course, assuming they are following similar procedures to the United States Navy.

[@patrickvonstieglitz5836]

While you are looking into the issue of the mast. Look at the fulcrum power that exhibited when two thirds of the mast is below the water line. The head of the mast as much as three metres below the surface. This is where the real Issue lies. How much power it takes to recover wether it’s full of water or not

[@zombieshoot4318]

They might simply just cut the mast from the boat to make it easier to raise the boat.

[@patrickvonstieglitz5836]

The investigation team already know the answered to the most important issues. The mast being removed absolute possibility by the time they have finished the boat will be in a million pieces.

The legal boat owner was actually Mike Lynch’s wife, Angela Bacares. She survived so I suppose she could have informed them. The captain also survived, I would imagine he knows that vessel better than anyone.

you shouldn't say the sliding doors are open and use the yacht report as a reference -because he didn't know for sure whether they were open or closed, so you are building on a secondary source and it turns into rumour stated as fact...

What is it about big boats that people see them and think, "Surely it must be unsinkable!"

[@SSPDIVING]

The Costa Concordia is a great example. I guess technically it didn’t sink though it ran aground 😂

[@tjroelsma]

Because the builders/owners always boast about the boats being unsinkable because they have watertight seperations, bouyancy that supposedly is greater than any amount of incoming water can overcome etc. Essentially, people tend to believe the lies that they're being told.

[@user-se7vt5ow4e]

As a retired yacht captain I always hated those large sliding glass doors and even more so the large transom doors. The last yacht I was on the sliding glass doors used compressed air to open and close the doors but if the compressor quit and the air pressure dropped the doors would freely open and close. The large transom doors are usually electric over hydraulic. There was a switch on the transom to open and close the door, the switch was supposed to be water proof but water got into the switch it shorted and the transom door opened while we were at sea. Murphy’s law is in full effect when you are at sea.
