Lynport Marina was a harbour.
Paul Langer went there with his son Clyde Langer. He used the Berserker pendant to make Clyde forget about his mother Carla, Rani Chandra and Luke Smith. At Lynport Marina Paul wanted to rent a yacht and travel the world with Clyde. They were stopped by Sarah Jane Smith, Rani, Carla and Luke. Paul Langer stopped using the pendant and Clyde threw it into the water. (TV: The Mark of the Berserker)
