The Sea Princess, on which this episode took place, was originally the Kungsholm, a Swedish American Line vessel. It was purchased in 1979, refit, and was renamed Sea Princess, sailing out of Australia until 1982. The current Princess Cruises Sea Princess, a much larger, elaborate, and streamlined ship, was commissioned in 1998 and is still in service.
Patrick Duffy (Ralph Sutton) and Jenilee Harrison (Connie Wilker) will go on to work together again on Dallas (1978) as Bobby Ewing and Jamie Ewing respectively.
