She was found unconscious at the back of the vessel at 1.45am.

She had worked her final shift as a stewardess onboard the six-storey yacht and was due to meet her mother and sister the following day after they had flown from Australia especially to see her. Her body is expected to be flown home on Tuesday afternoon. A British yacht, the Lady May of Glandore, had been docked next to the Mayan Queen IV when Ms McNamara was last seen alive. A crew member, who asked not to be named, said: 'The incident happened overnight when we were asleep. 'However in the morning it was clear something had happened and I asked someone who was delivering supplies to the Mayan Queen what had gone on. 'She had apparently been seen talking to another member of the crew, a security guard, some 15 minutes or so beforehand. 'I see the guard walking around the yacht at night making sure everything is kept secure. 'I don't know if he found the girl and raised the alarm but a captain of another yacht which had been docked on the other side to us went to go and help. 'He was unsure at first of what was going on and whether it was some sort of prank or hijinks but when he got nearer he could see that it was serious.'

However, a source at the Coastguard told MailOnline: 'She was found at the back of the yacht attached to one of the mooring ropes. 'The yacht had been docked immediately outside the Coastguard offices, which are manned 24-hours a day, so we were able to react to the situation quickly.' The coroner revealed he had advised Ms McNamara's mother, Kylie, and her sister, Lauren, against visiting her body in the morgue, saying they should not go 'to see her in such bad state'. The captain of another luxury superyacht made the grisly discovery of Ms McNamara's body, and has detailed how he tried desperately in vain to save her life. The captain of the boat, who asked not to be named, told news.com.au that he saw Ms McNamara's body about 1.45am on Friday. He shouted out to her but after receiving no response, he began screaming for help. The captain said a police patrol passed the Mayan Queen IV but did not see the young woman's body. Ms McNamara's mother and sister were on their way to Greece to holiday with her when crew on-board the Mayan Queen IV made the grim discovery A doctor on-board the Mayan Queen IV then tried to resuscitate Ms McNamara for several minutes after being alerted. After falling into a coma she was airlifted to an Athens hospital, but died on the way. 'We were actually celebrating at first because we thought she had been saved. It was later we heard she had died,' the captain said. He said he was deeply affected by the incident. The bikini model had been working as a crew member on the six-storey superyacht, owned by Mexican billionaire Alberto Bailleres, since May this year. She was just hours away from reuniting with her mother and sister who were mid-air on their way to Greece when she died last Thursday. Having been forced to cancel the holiday of a lifetime, they will now accompany Ms McNamara's body back to Australia. The Mayan Queen IV finally left the port on Monday night after being detained by the local authorities until the crime scene had been examined.
