1. What I'd like to know is why no one is asking why they didn't get divers in the water asap to look for trapped survivors? These people tried to fight, but ran out of air.

   The cause(s) of death lists the primary biological mechanism of death, (ie which body organ failed first) not the thing that caused that mechanism to occur. If someone is breathing when immersed in water they will inhale water into the lungs in which case it reaches all the way down to the bronchioles and alveoli, it's the presence of excess water in those regions that prevents gaseous transfer and cold water does not contain enough oxygen to sustain life. In this case the cause of death listed would be drowning… though it can occur if someone has advanced cardiopulmonary disease or has toxic substances causing the alveoli to produce an excess amount of fluid.

   Asphyxiation is listed as the cause of death when someone cannot expel sufficient CO2, either due to airway blockage or high concentration of CO2 in the inspired air. High (a relative term as the amount is very small) CO2 causes changes to blood flow and body cell metabolism. The body organ most sensitive to higher levels of CO2 is the brain.

   Once breathing has stopped water / inhaled fluid does not generally penetrate down to the level of the bronchioles and alveoli. An autopsy usually lists primary and secondary causes of death, the biological mechanism is the primary and the mechanical cause – immersion in liquid, strangulation, etc is the secondary. Though this can vary. It may also be that there is some water present in bronchioles and alveoli but not judged sufficient to be the primary cause of death as water can gradually get down into the lungs after a dead body has been immersed in water for an extended period of time

   When someone is immersed in water, particularly if it is cold, they have a 'dive reflex' which causes the muscles of the larynx to tighten narrowing the upper airway (it can be painful), the heart rate temporarily reduces and there is a release of adrenaline which worsens the airway muscle laryngospasm – it is a similar mechanism in an asthma attack. As CO2 levels rise in the blood the heart rate increases and the effect of the adrenaline and raised CO2 causes the fight or flight response – so panic. This is when the person begins to inhale water if their airway is immersed while they still have sufficient brain function to drive respiratory effort. When CO2 is dissolved in water it becomes acidic and brain cells are extremely sensitive to blood pH, it is that acidity that damages brain cells and causes the very small blood vessels to leak more fluid into surrounding tissue, if there is enough damage the brain as a whole ceases to function.

   Humans can tolerate low oxygen levels longer than higher CO2 levels (low blood pH), if someone is trapped in a confined space (or has taken a substance that can cause the part of the brain controlling breathing to cease functioning) the build up of CO2 causes asphyxiation that causes organised brain function to gradually cease, it is the brain function that drives respiratory effort hence an asphyxiated person lost brain function driving breathing before full airway immersion. In a normal person (without chronic heart or lung disease) it is not low blood oxygen levels that drive the breathing response, it is the elevated level of CO2 (low pH) that drives the breathing response. When we decide to give mechanical ventilation to a patient in ICU for example we do it to control blood pH, rather than to supply elevated amounts of oxygen as a person with weakened breathing has trouble expelling CO2. The part of the brain that controls breathing gradually ceases to function as CO2 levels rise above a certain level causing the blood pH to drop. So the question an autopsy is undertaken to determine is, did they inhale or retain too much CO2 before immersion causing breathing to cease before airway immersion (asphyxiation), or were they still able to breathe after immersion in water (drowning)? Water is heavier than air and more viscous, it takes quite a lot of respiratory muscle effort to pull in enough water to get down to the bronchioles.

   It may seem academic which was the primary cause of death for an individual, however these findings help to determine safety procedures and equipment provision, or design, in the future. Example escape hatches that do not have some illumination can become less useful in the dark to a disorientated person.

   Hope that helps.

3. Would not the divers mention if the bodies were found in a place with an air pocket ?

4. Did Bayesian only have one life raft ?

5. About 15+ years ago in Broward Shipward a couple working on another boat returned after a night out. Apparently the guy got back to the boat first and fell in his bunk. His girlfriend fell into the water and no one knew she was missing until the morning. The police dragged the water all day then finally found her body. Also, Ive often had to kick people off boats who thought it was a good idea to board for a laugh. Happened in Florida, Cannes, and the Bahamas.

6. It's all very, very suspicious given the people who died

7. I think some dirty low life is having nightmares over what `thev`ve` done…Accident my arse. The truth will out as they say [if Karma fails]

8. Stray AC voltage in a marina's water can be lethal. They used to assume it was accidential drowning, but actually electrocution. That's why swimming isn't allowed in marinas anymore. The stray voltage can leak from the boat's onoboard AC into the water via the hull's grounding to shore power. Or from a nearby boat to the shore hotel AC grounding at the pier.

   Away from other boats or the dock is much safer.

9. Was it that Australian break dancer?

10. That video of the girl jumping onto the stern was taken in Port Canto, Cannes. Seen it there for many years, docked right infront of Baoli (night club)

    Never seen a crew member at night, assumed no one stayed onboard. Its not uncommon for people to take chances and jump onboard yachts. Seen it many times. We often have people try to step up on our passerelle to take a look. Dangerous and disrespectful if you ask me.

11. Where is portside?

12. While this was a tragic accident it should be compared to the thousands of men, women and children who drown in the Mediterranean every year while they seek a better life in Europe. Not rich, not powerful, and not from luxury yachts.

13. Another reason for removing the boarding plank it to stop rats getting in the boat. We had rat lines, with discs to stop them coming aboard. Still got one in the boat in Egypt (rat infested dump) that took a week to catch!

14. About the careless young women.
    
    There is a rope at the lower left, she didn't hit her head, and I hear a concerned voice at 10:30.
    
    So I have high hopes that all ended well.

15. He could do this chat in 5 minutes instead of 13, if only he would not repeat everything all the time

16. That yacht was dinky looking relative to what a billionaire can afford to charter. As with most things in life, cheaping out has consequences.

17. if only he had some cans of peri-air 😅

18. Darwin Awards used to be awarded to people who died doing things like this. Very easy to get seriously hurt in that situation … but drunks seem to have at least 80% of the luck with regards to these accidents.

19. All people of the sunken boat look totally evil. They woukd not care as long as they make another Euro or Dollar. Time was up. And why I would care what happened to them? Please explain that because there you might need not to speculate.

20. 11:32 it looks like that “jumper” didn’t land well and face-planted on the transom! She collapsed when she landed- her fail

21. Is it possible that the victims died suffocated and not drowned because of the effect of the air making a vacuum effect inside the cabin ? I myself experienced being breathless with a suden gust of wind, but nothing compared with this disaster.

22. There is also something called secondary drowning. When lungs get inflamed from being exposed to water and swell and exude fluids…

23. Probably no one o the bridge?

24. I am no Dr. but 5 people in a air pocket with water around them would not last very long. The oxygen levels would have depleted rapidly and they in turn would have excelled carbon dioxide. Any further rescue attempt would have been futile due to the depth of the sinking. As previous professional comments as to decompression and no diving bell, the poor souls were doomed.
