Overview
SS The Emerald was a passenger ship whose career spanned the transition from traditional ocean-liner service to the modern cruise industry. Built in Newport News, Virginia, for the Grace Line, she entered service in 1958 as Santa Rosa, one of two new liners intended to replace Grace Line's earlier 1930s vessels. Her sister ship was Santa Paula. The ships were designed by Gibbs & Cox and featured a number of advanced characteristics for their period, including full air conditioning for passengers, Gyrofin stabilizers, all-outside passenger cabins, private bathrooms, fire-resistant aluminum interior construction, and cargo-handling arrangements intended to accelerate port turnarounds. Santa Rosa initially operated scheduled passenger and cargo services between New York, South America, and the Caribbean. Her maiden voyage took place on October 10, 1958. During that voyage she became the largest ship to travel up the Hudson River to Albany, New York, and she also made a notable first appearance in New York Harbor from the north. Her early career was interrupted by a serious collision with the tanker SS Valchem in heavy fog on March 26, 1959. No one aboard Santa Rosa was injured, but four tanker crew members died and sixteen others were injured. The liner suffered substantial damage, including damage to her bow, boilers, and power systems, but she was repaired and returned to operation. The decline of scheduled transatlantic and international liner services led to the end of Santa Rosa's original career. After Grace Line merged with Prudential Lines in 1970 to form Prudential-Grace Line, passenger operations stopped in 1971. The ship was laid up at Hampton Roads, Virginia, alongside Santa Paula. A number of proposed revivals followed. The vessel was obtained by the U.S. Department of Commerce in 1975 and sold in 1976 to Vintero Corporation, which renamed her Samos Sky. A planned South American service did not materialize, leaving her inactive for many years. In 1989, Samos Sky was sold to Coral Cruise Lines, part of the Lelakis Group, and moved to Greece. She was renamed Pacific Sun and later Diamond Island during a major conversion. The approximately $70 million modernization expanded her superstructure and transformed the ship for cruise operations while retaining her hull and original steam-turbine machinery. The machinery was refurbished with parts from the former Santa Paula, and the conversion was completed in 1991. The rebuilt vessel entered service in 1992 as Regent Rainbow for Regency Cruises. Regency later suffered major financial losses and entered bankruptcy in 1995; the ship was placed under arrest that November. Louis Cruise Lines acquired her in December 1996 and renamed her The Emerald. From 1997 she was chartered to Thomson Cruises, serving the British holiday market. The ship became Thomson's most popular vessel, but the company removed her from service in October 2008 in favor of a larger, newer, and more economical ship. After limited subsequent service for Louis Cruise Lines, the vessel was laid up in Greece in 2009. Although her owners sought another operator and considered her compliant with SOLAS 2010 requirements, no long-term service was secured. She remained at Eleusis and was eventually sold for demolition. In July 2012 she departed Greece for Alang, India, where she was scrapped under the shortened name Emerald. Her retirement ended the active career of what was described as the last passenger ship built at a U.S. shipyard that remained in service.
History
The vessel that later became SS The Emerald was ordered in 1956 by the Grace Line as part of a pair of replacement liners for the company's aging Santa Rosa and Santa Paula, which had been built in 1932. Gibbs & Cox designed the new ships, while Newport News Shipbuilding and Drydock constructed them at Newport News, Virginia. The new Santa Rosa was launched on August 28, 1957, and delivered on June 12, 1958. The ship embodied several features associated with advanced postwar liner design. She was fully air-conditioned for passengers and was among the first American passenger ships equipped with Gyrofin stabilizers. Her interiors were designed by Dorothy Marckwald and Anne Urquhart, designers also associated with SS America and SS United States. The accommodation plan gave every passenger cabin an outside view and a private bathroom. Aluminum fireproofing was used in the interior, while two aft cargo holds included side doors and automatic conveyors for rapid pallet handling. This combination reflected the Grace Line's need to carry both passengers and cargo efficiently. Santa Rosa entered scheduled service between New York, South America, and the Caribbean. Her maiden voyage began on October 10, 1958, and included a trip up the Hudson River to Albany. She became the largest ship to make that voyage and made a distinctive first appearance in New York Harbor from the north. Her early service was not uneventful. On March 26, 1959, while returning to New York in heavy fog, she collided with the tanker SS Valchem approximately twenty-two miles east of Atlantic City, New Jersey. Santa Rosa's bow penetrated deeply into the tanker, whose lower engine room flooded and whose power was lost. Four tanker crew members were killed and sixteen injured, while the liner's passengers escaped injury. Santa Rosa sustained heavy damage, including the destruction of two boilers, but was repaired. The economics of scheduled passenger shipping deteriorated during the following decade. Grace Line merged with Prudential Lines in 1970, creating Prudential-Grace Line, and passenger operations ended in 1971. Santa Rosa was laid up at Hampton Roads with Santa Paula and offered for sale. The U.S. Department of Commerce obtained the ship in 1975, and Vintero Corporation of New York bought her in 1976, renaming her Samos Sky. An intended revival of South American service failed, leaving the ship idle. Coral Cruise Lines, part of the Lelakis Group, acquired Samos Sky in 1989 and towed her to Greece. She reached Chalkis in March 1990 and passed through the names Pacific Sun and Diamond Island. A major conversion costing approximately $70 million transformed the former liner into a cruise ship. Her superstructure was enlarged, but the original hull remained substantially intact. Her steam-turbine machinery was retained and refurbished using parts from the former Santa Paula. The work was completed in 1991. The converted ship entered service in 1992 as Regent Rainbow under Regency Cruises. Regency experienced substantial losses and entered bankruptcy in 1995, after which the ship was placed under arrest in November. Louis Cruise Lines purchased her in December 1996 and renamed her The Emerald. From 1997 she operated under charter to Thomson Cruises, now known as Marella Cruises, primarily for the British holiday market. Thomson regarded her as its most popular ship, but withdrew her in October 2008 as larger and more efficient tonnage became available. Louis retained the vessel for limited further use after the Thomson charter ended. In 2009 the company announced that she would be laid up and was unlikely to return to service. The owners explored the possibility of another operator, noting that the ship met SOLAS 2010 requirements, but no new sustained commercial role emerged. She stayed at Eleusis, Greece, and was inspected by shipbreakers in 2011. In July 2012 she sailed to Alang, India, where she was scrapped as Emerald. Her disposal marked the end of the active career of the last passenger ship built at a U.S. shipyard that was still in service.

Ocean liner · 1958
Santa Rosa
The ship's original identity under Grace Line. Santa Rosa was a postwar passenger and cargo liner serving New York, South America, and the Caribbean. Her design combined spacious, fully air-conditioned passenger accommodation with cargo-handling equipment intended to reduce time in port. All passenger cabins faced outside and included private bathrooms, while Gyrofin stabilizers and fire-resistant aluminum interior construction reflected contemporary advances in passenger-ship design.
Cruise ship · 1992
Regent Rainbow
The name used after the ship's extensive Greek conversion for Regency Cruises.
