St Helena

 St Helena at Fairlie pier, the former Royal Mail cargo-passenger vessel, was one of the final two ships to carry the RMS title. She acted as a supply ship and ‘lifeline’, sailing between Cape Town and the remote British Overseas Territory of Saint Helena – a volcanic tropical island in the South Atlantic Ocean – between 1990 and 2016.
