Norwegian America Line
On 22 May 1973, Vistafjord set on her maiden voyage, a transatlantic crossing from Oslo to New York.[1][5] In early 1980, the vessel was famously chartered by car manufacturer British Leyland to internally launch the Austin Metro to its British dealer network.
Although their ships were high-rated, Norwegian America Line had trouble making profit.[8]
Cunard Line
In 1983 Trafalgar House, the owners of Cunard, purchased NAL[9] and in October 1983 Vistafjord joined the Cunard fleet together with her fleetmate Sagafjord. She retained her original name and the grey NAL hull colour, but received Cunard Line funnel colours and was re-registered to the Bahamas.[1] Despite the flag change she retained Norwegian command staff.[10]
During this time, both Vistafjord and Sagafjord, were considered to be amongst the most luxurious cruise ships in the world, sharing the top 5 in Berlitz Complete Guide to Cruising, together Sagafjord and Royal Viking Line's Royal Viking Star, Royal Viking Sky and Royal Viking Sea for several years.[11]
In 1999 the decision was made to rename Vistafjord with a more traditional Cunard Line name. On 10 December 1999 she was renamed Caronia and re-registered in the United Kingdom.
Saga Cruises
She continued service with Cunard until November 2004, when she was sold to Saga Cruises. Following a £17 million refit[12] at Valletta, Malta Caronia reappeared as Saga Ruby in March 2005.[1] In the Saga Cruises fleet she joined her former Norwegian America Line fleetmate Sagafjord (now named Saga Rose).[13][14]
It was reported in 2012 that Saga Cruises would retire Saga Ruby in 2014 and the Quest for Adventure would move back into the fleet as Saga Pearl II.[15]
Farewell voyage with Saga
She sailed her final world cruise in the first months of 2013. However it was marred by technical difficulties which kept the ship in Southampton until late February, which led to the cruise being renamed the 'Grand Voyage' visiting South America and South Africa.
It was reported that Saga Ruby would depart on her final cruise with Saga Cruises on 7 December 2013 round trip from Southampton on a 31-day voyage to the Caribbean.[16][17] While on her final cruise she was forced to change her itinerary to a Western Mediterranean cruise finally returning to Southampton on January 7, 2014. The cruise returned to Southampton late due to poor weather in the Bay of Biscay, eventually arriving on 9 January 2014, with passengers disembarking on 10 January.[18]
Floating hotel Oasia
In January 2014 she was sold for $14 million USD to Millennium View, a privately held company based in Singapore. The new owners planned to convert her into a floating hotel in Myanmar.[19] In mid-February 2014 she sailed from Gibraltar as Oasia under Bahamas flag and management of FleetPro Ocean.[20][21] In February 2017, it was announced that Oasia was being sold for scrap. The ship, was still SOLAS compliant and had recently undergone a US$10 million overhaul as a hotel and museum ship. She was found in Thailand, awaiting tow to scrapping, after having US$20 million invested in her.
