Early post-war years
On October 29, 1947 Nieuw Amsterdam left Rotterdam for Hoboken for the first time in seven years.[66] She called at Southampton,[67] and on November 6 entered the Hudson River to a traditional welcome of fireboats making a display with jets of water, and ships and boats giving three blasts on their whistles. At Hoboken she landed 1,256 passengers.[62] On November 10 she left Hoboken for Rotterdam, carrying 604 passengers, and 44919 lb of charity relief supplies for the Netherlands.[68]
On December 4, 1947 Nieuw Amsterdam left Hoboken on a cruise to the Caribbean: her first cruise since May 1940.[69]
Until 1940, NASM transatlantic ships had served Boulogne. After the war this did not resume, because the port of Boulogne was not yet in a condition to resume handling large ocean liners. Instead, from February 3, 1948, Nieuw Amsterdam started calling at Le Havre.[70]
In 1948 some of her westbound crossings were almost fully-booked. The number of passengers she landed at Hoboken from Europe was 1,190 on August 10,[71] 1,244 on November 3,[72] and 1,201 on December 19.[73] Among them were the writer Aldous Huxley on November 3,[72] and Ralph Bunche on December 19, returning from his work assisting the United Nations Special Committee on Palestine.[73] Notable passengers sailing east on Nieuw Amsterdam that year included the exiled royal family of Yugoslavia: King Peter II, Queen Alexandra, and their young son Crown Prince Alexander, who left Hoboken for France and Britain on July 24.[74]
Nieuw Amsterdam was scheduled to make five cruises in the 1948–49 season.[75] The first carried 800 passengers.[76] It left Hoboken on December 21, called at San Juan, La Guaira and Kingston, Jamaica,[77] and got back to Hoboken on January 3, 1949.[78] Her third cruise was an 18-day voyage that added Cap-Haïtien and Ciudad Trujillo to her more usual ports of call. It left Hoboken on January 21, carrying 650 passengers. Two similar cruises followed.[75] On March 24, 1949, she resumed her transatlantic service, leaving Hoboken with 1,120 passengers for Europe.[79]
The Master of NASM's flagship was customarily commodore of the company's fleet. Nieuw Amsterdam was the flagship from her introduction in 1938 until the introduction of the new SS Rotterdam in 1959. The flagship was entitled to a special version of the NASM's green and white house flag, which had an orange star in one corner.[80] In June 1949 NASM appointed a new Master to Nieuw Amsterdam, Cornelis HP Coster, who was also a commandeur in the Royal Netherlands Navy Reserve. This entitled Nieuw Amsterdam to fly the ensign of the Dutch naval reserve while he was in command.[81] Coster retired in October 1950.[80]
In 1949 the ship continued to be almost fully-booked on some crossings. The number of passengers she landed at Hoboken from Europe was 997 on June 28,[82] 1,230 on September 4,[83] 1,201 on October 19,[84] and 1,038 on December 14, including the composer Samuel Barber.[85] On August 16 she left Hoboken for Europe carrying 1,025 passengers, including the sculptor Jacob Epstein, pollster George Gallup, and actor Walter Pidgeon.[86]
For the 1949–50 cruise season, Nieuw Amsterdam was to make a series of Caribbean voyages, and then end the season with a 50-day circumnavigation of South America. Her first Caribbean cruise left Hoboken on the night of December 17–18, 1949, carrying 600 passengers. New ports of call included Fort-de-France, and Cartagena, Colombia.[87] On January 6, 1950, she left Hoboken on a 13-day Caribbean cruise carrying only 400 passengers.[88] However, on January 21 she began her next 13-day cruise with 675 passengers.[89]
Her voyage around South America began from Hoboken on February 8. 607 passengers paid a total of US$2.7 million in fares. Her route was via Havana to the Panama Canal, then anti-clockwise around the continent: down the Pacific coast of South America, up the Atlantic coast, and into the Caribbean to visit Trinidad, Curaçao and Jamaica before returning.[90] She got back to Hoboken on March 29.[91] On March 31 she resumed her transatlantic service, leaving Hoboken for Rotterdam.[92] NASM claimed that demand for transatlantic travel in 1950 was high, with many sailings scheduled for later in the year already fully-booked by February.[93]
On December 20, 1950, the ship left Hoboken on her first Caribbean cruise of the 1950–51 season.[94] She returned on January 1, 1951.[95] That winter, using both Nieuw Amsterdam and a smaller liner, SS Veendam (1922), NASM ran seven cruises, which carried a total of about 4,000 passengers.[96]
