The Big U would remain unchallenged for the next 38 years - until 1990 when the catamaran Hoverspeed Great Britain claimed the transatlantic record with a time of 3 days and 7 hours. When her owners tried to obtain the old Hales Trophy, however, a controversy erupted.
The award had been set up specifically for passenger liners; the United States Lines American Merchant Marine Museum - which displayed the prize - refused to relinquish the trophy. The Hoverspeed Great Britain had not carried any passengers on this crossing, which was considered a key requirement for the award. It had been an eligible contender, however, as the award's British trustees approved the attempt.
The Americans were ready to take their claim to court, but ultimately decided against it. Carnival Cruise Lines would later give the American Merchant Marine Museum a replica of the Hales Trophy.
