I'll take a guess... It's a Minett Shields called the Alzeda, once owned by Tom Mittler. She has been sunk and rebuilt on at least 2 ocasions.
The second one (via simple Google Image search) The 111.91ft /34.11m Leopard 34 open 'Koji' was built in 2012 by Leopard.
Social networks, for instance someone post a picture of his car in front of the harbour, I don't care about the car I want to know the name of the yacht, this is curiosity.
