MV Regent Sky was an unfinished cruise ship that travelled to several locations during her incomplete construction.

[6] Stena Baltica was towed to the Avlis Shipyards at Perama, Greece (also owned by Lelakis), where a US$200 million process to convert her into a cruise ship began.

The vessel was renamed Regent Sky at this time, and 7,000 tons of steel were installed after she was lengthened 50 meters at Elefsis Shipyards in Greece.

In 1995, while Regent Sky was at the Avlis Shipyards of Chalkis, Greece and about 60% finished, Regency Cruises ceased operations.

[1][7] This ship, the longest-lived passenger liner that was never completed, finally arrived for demolition in Aliaga, Turkey on 16 July 2012.
