Bentivoglio Fiandra, chief of Palermo's fire brigade and part of the divers' rescue team, explains that the Bayesian sank stern-first and then rolled onto its right side.
As a result, the victims sought refuge on the left side of the boat, where the last air pockets remained as the vessel was sinking.
They found five bodies in the first cabin on the left and one, Hannah's, in the third cabin on the left.

Palermo coastguard deputy commander Raffaele Macauda then comments on the technical aspects of the rescue.
He highlights that the coastguard is conducting in-depth environmental monitoring and notes that the yacht's owner has expressed a desire to recover and resurface the vessel.
He also emphasises that the owner has been in contact with the coastguard regarding this matter.

Why was the crew able to get into a lifeboat, when the passengers couldn't?
The first question from reporters is: how come the crew were able to get into a lifeboat, when the passengers couldn't?
In response to the question, one Italian official says the incident happened "really suddenly" and the inquiry will be looking into this closely.
"That's all I can say at the moment," the official added.

'Is there a black box?'
The next question comes from La Repubblica newspaper, as one of their reporters asks if there is a black box and why the hatches were left open.
"We haven't got exact information about the black box," the official says.
"It was extremely difficult to get inside the cabins and the yacht itself," adding that the first phase of the inquiry will be looking into this further.
He says they cannot reveal anything further at this stage, but the facts will be confirmed by the later search amongst the wreckage - including whether the divers found them open or closed.
"We don't want to give mistaken information now that we'd have to deny later," he adds.
Captain and crew of the vessel are not required to stay in Italy

Cartosio confirms that charges could be pressed against one or more specific individuals well before the recovery of the Bayesian.
He also states that the captain and crew of the vessel are not required to remain in Sicily for the entire duration of the investigation.
However, the chief prosecutor expresses a desire for them to "remain available for further questioning," as this may be needed in the future as the investigation progresses.
Downburst appears to have caused sinking rather than waterspout

Reporting from Sicily
Deputy Prosecutor Cammarano explains that the reason why almost all the crew, except for the yacht's chef, managed to get to safety and the passengers didn't, is likely that the passengers were asleep at the time of the incident.
He also adds that, based on what they know now, it is unlikely that a waterspout caused the sinking of the Bayesian. Instead, it appears to have been caused by a downburst.
A downburst is a localised, powerful wind that descends from a thunderstorm and spreads out rapidly upon hitting the ground, generally in an unpredictable manner.
Diver describes rescue operation
10:25 BST
We're now hearing from one of the divers, an engineer diver, who describes the rescue operation from his perspective.
He recalls that the vessel was sunk at 50m depth, and getting into the cabins made it even more difficult.
He describes all the obstacles preventing them from getting into the vessel, adding all safety measures had to be properly observed to ensure divers did not risk their lives any further.
"It was particularly difficult, and it was very slow, very slow work," he adds, as it required "very lengthy periods to remove the obstacles through the cabins".
'Why were passengers left behind?'
10:35 BST
Local officials are also asked about the location of the bodies in the yacht, as most bodies were found in a particular part of the ship - does it imply the passengers tried to save themselves?
"There is no certainty of the behaviour of the passengers on board, but it's probable that they tried to escape, but we have no real details about that," an official on the panel says.
He says there should be some evidence emerging from the wreckage retrieval location.
Officials are also asked why passengers were not able to flee the boat at the same time as crew members and whether someone alerted them.
"Well, that's precisely what we're trying to ascertain from the statements from the survivors," one of the officials says.
Asked about the cost of the retrieval, the coastguard admiral says the owners will bear the full cost of the retrieval and he cannot estimate how much that will be at this stage.
