The Santa Rosa's had two aft cargo holds had side doors and automatic conveyors to quickly move pallets on and off the ship, thus giving her a rapid turn-around at port.

Santa Rosa’s bow punched a cavity extending halfway into the tanker and caused flooding of the lower engine room with resultant loss of power.

[11] In 1975, Santa Rosa was obtained by the U.S. Department of Commerce and in 1976, she was sold to Vintero Corp. of New York City and renamed Samos Sky.

In March 1990, Samos Sky arrived in Chalkis, Greece and was renamed Pacific Sun and then, later that year, Diamond Island.

[5][15] At the cost of $70 million, she was converted into a cruise ship; her superstructure was expanded, whilst her hull remained largely unaltered and she retained her original steam turbine engines, which were renovated with parts from the former Santa Paula.

[6] During her time with Thomson she became the company's most popular ship,[17] and remained in service with them until October 2008, when she was dropped in favor of a larger, more modern and economical vessel.

[19] Following the departure of The Emerald from their service, Louis looked for other owners who would operate her for further use, since she met SOLAS 2010 regulations, but she remained laid up at Eleusis, Greece.
