Peacetime HAPAG service
HAPAG registered Prinz Joachim at Hamburg. Her code letters were RNBJ. In October 1903, she joined her sister ship Prinz August Wilhelm on HAPAG's route between Hamburg and Mexico.
In September 1905, the Royal Mail Steam Packet Company (RMSP) announced that it would start running a fast passenger service between New York and Jamaica. HAPAG responded by announcing that it would put Prinz August Wilhelm and Prinz Joachim on its Atlas Service, which ran various routes between New York and the Caribbean.[2] In June 1906, HAPAG announced that it would transfer its cruise ship Prinzessin Victoria Luise to the New York – Jamaica route, and that Prinz Eitel Friedrich, Prince Waldemar, Prinz August Wilhelm, and Prinz Joachim would all work the route between New York and Colón via Kingston.[3]
On 14 January 1907, an earthquake struck Kingston. New Yorkers formed a relief committee, which had Prinz Joachim loaded with relief supplies including food including barrels of beef, flour, and lard.[4] She was to sail on 19 January, but fog delayed her until the next day.[5][6]
On 5 June 1907, Prinz Joachim reached New York from Central America carrying passengers including former President of Honduras Marco Aurelio Soto, and the US explorers Hiram Bingham III and Alexander H. Rice Jr.[7][8]
On 4 November 1909, just after Prinz Joachim docked in New York, the Purser's personal steward let himself into the Purser's office, unlocked the safe, stole $8,065 in US currency that passengers had entrusted to the Purser, and then absconded from the ship.[9] It was the first such theft from a ship in New York for 25 years.[10]
On 9 January 1910, Prinz Joachim was leaving Kingston for Colón when she ran aground on soft mud. The German cruiser SMS Hertha (1897) went to her assistance.[11] The next day, both her sister ship Prinz Eitel Friedrich and Hertha tried to pull her free, without success.[12] However, by 11 January, she had been refloated, undamaged, and resumed her voyage to Colón.[13]
In April and May 1910, a series of earthquakes destroyed the city of Cartago, Costa Rica. Prinz Joachim was in Puerto Limón at the time, and contributed her ship's doctor and five of her stewards to a relief expedition that was sent by train to Cartago. The five stewards were all former Imperial German Army nurses.[14]
By 1910, Prinz Joachim was equipped with wireless telegraphy. By 1913, her call sign was DSP. In the fall of 1910, Prinz Joachim made a 51-day Caribbean cruise. She used her wireless to report her progress to HAPAG's New York office. The cruise included a visit to Colón, which coincided with President Taft visiting Colón aboard a United States Navy squadron. Prinz Joachim displayed an illuminated sign of more than 2,000 electric lights saying "Welcome Taft".[15]
Aground off Samana Cay
On Saturday 18 November 1911, Prinz Joachim left New York for Kingston. The former Congressman William Jennings Bryan and some of his family were among her passengers. At 03:40 hrs on 22 November, she grounded on rocks off Samana Cay in the Bahamas.[16] Prinz Joachim sent wireless signals calling for help, but received no answer for "several hours", because not all ships carried wireless equipment, and not all those that did carry it had enough wireless operators to man their receivers 24 hours a day.[17]
The Ward Line steamship Seguranca was the first ship to arrive to help. She took off all 84 of Prinz Joachim's passengers, plus some of her mail.[18]
A number of boats transferred passengers between the two ships. At the end of the operation, a high sea drove one of Prinz Joachim's boats off course, and prevented it from returning to the ship. It had 18 crew, commanded by her second officer.[19]
