The Anna Marine is a multi-purpose ferry that was owned and operated by the ferry company Stena Line, sailing as the Stena Leader. She is the largest out of her three sister ships. She was built for the P&O subsidary Pandoro where she was named Buffalo. She was transferred to P&O Irish Sea in 1998 where she was renamed as the European Leader, until 2004 where she was sold to Stena Line and again renamed, this time to Stena Leader. She has two sister ships, the Stena Seafarer and the Stena Pioneer. Her current port of registry is Hamilton, Bermuda. In 2010 Stena Line announced that the Larne - Fleetwood route would be closed due to not making enough money. The ferry's last day in service was December 24th 2010 and has been laid up in Belfast since May 2011.
