Strange when it was introduced to back up a theory it was windy...
Actually you are entirely wrong.
I was originally asked by another if there was anyone sailing at 10pm. The answer to that was that there was at least one but at least one which was unaccounted for at the time of Madeleine's disappearance.
Therefore the theory being 'backed up' was not entirely the irrelevance of whether or not it was windy but how Madeleine could be abducted from her bed to vanish as completely as she did. Abduction, transport and the means and planning to do so.
She and the other children were very visible in their routine such as when playing in the play area before bedtime.
SnipThe mystery boat had been sailing along the Algarve coast close to Praia da Luz where Madeleine disappeared.
And records show it has previously docked at Barcelona’s Marina Port Vell, next to the Olympic Marina where the Australian woman was spotted.
The Portuguese source said: “It’s possible that the boat went to Barcelona. The yacht left Portimao on the morning of May 4, 2007.
“It left saying it was going to Albufeira in Portugal. It is a legal requirement to give a destination but it did not arrive in Albufeira.
“There were six boats that left Portimao that day. All have been accounted for apart from the Swedish boat.”
In Sweden all vessels measuring over 12 metres (40ft) long must be registered with the Swedish Maritime Administration.
But inquires with their head office in Stockholm yesterday found no record of the yacht.
