56M Perini S/Y Bayesian Sinks During Palermo Storm

For this thread, start at 6:00.
Around 6:30 some comments on Bayesian sliding doors.

I think the problem and quotes on the doors, for a fourteen year old yacht are over-kill. Getting it from a live TV-show is also even more over-kill.
Honestly I did not accept it from Essyman who gets carried in these things. But hey everyone on social media is looking for the extra click nowadays.
The next thing we should say is how many people actually crashed into the glass of a patio door, because your visual thinks it is open, but also it is closed.
I do not know to how many it happened (me included), and how many slipped in some cabin stairs cause they are too steep.

Door problems are common on new yachts (one of many,), if the first captain was responsible they are fixed usually after some weeks or a couple months, and then after a couple years stuff breaks again. No big deal. I do not know how many new yachts I have seen, that they have to duct tape side doors, on the first delivery trip cause they could not be close correctly.
I am not saying the door could not have that defect at the time of sinking, stuff on yachts breaks every time, it is a fact, whatever the yacht is, even a Perini or a Lurssen.
But please do not over kill it on the subject, without any proof.

Hi Pascal
Sometimes/often there is a fresh air makeup unit (FAMU) which draws outside air into the boat to mix with the board air and provide a slight positive air pressure which in theory prevents humid warm air entering the yacht when exterior doors are opened.
The FAMU “supercools” the exterior air to about 60F to remove humidity and then heats it to ambient (such as 70F). But not all boats have that. I’ve seen mostly on 50M+ yachts.
The FAMU intake is usual up forward and up high, like in the Portuguese locker forward of the bridge, away from galley & engine exhaust.
Don’t know if this is installed on Perinis. If it is it is probably just a 10-12” intake duct.

Horrible subject, but it belongs smack in the middle of this thread, 6 died, 5 stuck inside the sinking boat, but it seems the chef drowned outside or got out too late.

I googled death by drowning out of a somewhat morbid curiosity:
(Been close a few times)
Supposedly drowning may be somewhat peaceful after the initial reflex reaction to hold the breath is over, and you start inhaling water then breathing it in and out, not much oxygen in the water, no gills, you die.
Don’t want to try it, but several victims who almost drowned then got resurrected said the same, Including my dad, who grew up in Northern Norway next to the beach and fell in after playing dare-you on a chunk of ice in the fjord. He was pulled in motion less, the doctor came but gave up on resuscitation, the mother didn’t give up and after 1/2 hour my old man was alive again: Cold water helps, not sure what is was in the Mediterranean in August, 24 Celsius perhaps, less at 50 meter depth, 5-6 C maybe.
Too bad the trapped owner and his guests couldn’t swim out from the air bubble.
If this is a learning experience, every Big Yacht owner should specify battery powered and water proof emergency signs and lights with arrows pointing to the nearest exit after this disaster.
I would.

Mentions the likelihood of the side deck wells and the salon doors causing the downflooding. Which, if a factor, questions the CEO of Italian Sea Group.

Taken from the stability booklet, this table shows downflooding actually begins around 30° with the board up. The opening is a 'small' opening forward, with a cross-sectional area of 500cm^2.

This opening was not determined to be critical due to its size and possibility of progressive downflooding. However, it's highly likely that any volume of water taken in through this opening would result in a reduction of the calculated righting characteristics, leading to greater heel angles being reached more quickly than anticipated.

I wouldn't say this theory was largely dismissed.

It was discussed back on page 3, on 22nd August. And several times since. Before additional information was made available, e.g. the excerpts from the stability booklet, it remained a hypothesis that may or may not have been realistically feasible.

Although still hypothetical, it looks much more likely as the technical data shows a vessel that would be readily susceptible to such an event.

Damage to the image of the builder was hampered when "the bow fell off".
