Sharon Bugeja, the wife of the only survivor, said she completely believed her husband's version of events even after the two had separated.
Mrs Bugeja said she had no reason not to believe her husband's version of how 11-year-old Theo had died in the evening of July 17.
The mother said her separation from Mr Bugeja had nothing to do with the accident and their relationship had been deteriorating for some time.
Mrs Bugeja was very bitter that the captain of the Laura II had been instructed not to say anything by the AFM when Noel Carabott was found on Thursday afternoon, saying that if fishermen had been informed of the corpse's find they might have found her son alive.
When it was suggested that the boat could either have been carrying explosives or fishing illegally, she said she would not have sent her son out on the boat had she thought, or known, of such a situation.
Mrs Bugeja said she did not think she had told Mr Carabott's widow, Stephania, that she did not want to inform the authorities the boat was missing since it could be confiscated.
Mrs Carabott had insisted on this in every interview she gave on the subject in the past year. But Mrs Bugeja said that if she had a clue of what had happened, she would not have cared less about the boat.
In the first of two interviews, Mrs Bugeja said she was unable to access the Simshar's vessel monitoring system during that trip, even though she had a computer system at home. The reply was always "season closed".
She last heard from Mr Bugeja on Wednesday, July 16, when he sent her a text message by satellite phone asking for a weather report for Lampedusa. Although he later said their son had answered another text message from her, she never received this.
Although she said it was normal for the fishermen to return on a Friday, when they did not go back home she assumed they had cast another line. When they had not returned by Saturday afternoon, she went down to the harbour and asked fishermen whether it was normal for the Simshar to cast its lines for the sixth night in a row, but was told that they did not know. This was when she started to panic and contacted the armed forces. She went to hand them a photo of the boat the next day.
