SS Guglielmo Marconi

SS Guglielmo Marconi was a ocean liner launched on 24 September 1961 for Lloyd Triestino's Genoa—Sydney service. Her sister ship was SS Galileo Galilei. Guglielmo Marconi made her maiden voyage in November 1963. In 1976, Guglielmo Marconi was transferred to the Naples-Brazil-River Plate service of Italia Line. In 1979 she was transferred to Italia Crociere as a fulltime cruise ship. This was not a success and she was destined to Costa Lines in 1983.

After a two-year rebuild, the ship reappeared as SS Costa Riviera for Costa Cruises in 1985. Costa Riviera alternated between Caribbean and Alaskan cruising until 1993. In this year American Family Cruises was launched, a joint venture between Costa and Bruce Nierenburg, to operate cruises aimed at young American families with children. AFC were not successful, and the ship sailed for Genoa in September 1994 where she was converted back to the Costa Riviera, and began cruising in Europe. Costa Riviera was sold for scrap in 2001.
