In 1966 she was sold to the South Africa-based Safmarine and renamed S.A. Vaal for further service on the same route. Following cessation of the service between the UK and South Africa in 1977 the ship was sold to Carnival Cruise Line and rebuilt in Japan as the cruise ship SS Festivale, re-entering service in 1978. In 1996 she was chartered to Dolphin Cruise Line and renamed IslandBreeze. In 1998 the ship was sold to Premier Cruise Line, which renamed her The Big Red Boat III. Following the bankruptcy of Premier Cruise Line in 2000, The Big Red Boat III was laid up until 2003 when she was sold to scrappers in Alang, Indi
