The Lensahn (III) was a luxury yacht owned by Grand Duke Friedrich August von Oldenburg , with which he and his family made several extended trips. Her home port was Oldenburg . During the First World War , she served the Imperial Navy as a hospital ship . It was sold to Sweden and the USA after the war and sunk off the coast of Florida in 1934 . The wreck , located at a depth of over 20 meters, was identified around 2007 and is now known as the South Jack Wreck of Tampa Bay .

The ship was named after the ducal estate Lensahn in Holstein .

Furnishing

The Lensahn in Brunsbüttelkoog

It is known that Grand Duke Friedrich August dealt intensively with ship technology, so he developed his own type of propeller, the NIKI propeller with improved efficiency, which he patented and which was also used on this yacht. He also had a high-performance radio system from DEBEG installed, which was not exactly common at this time.

The Lensahn (III) was the successor to the Lensahn (I) (1881–1890) and the Lensahn (II) (1890–1901), both of which had also been built at the Howaldtswerke shipyard in Kiel . Friedrich August was not present either when the yacht was launched or when it was put into service. As early as 1903, the yacht was massively rebuilt under the direction of Johann Schütte , so that the external dimensions changed considerably. A second chimney was also installed.

The yacht served various trips abroad until 1914, including to Morocco and Constantinople . The berth in the Oldenburg harbor was the turning port, which is still used today as a berth for yachts of an Oldenburg water sports club.

When war broke out in 1914, Friedrich August made the ship available to the Imperial Navy, which put it into service as a hospital ship on October 19, 1914. Special features of the service are not known; the war diary is in the Federal Archives-Military Archives . On November 13, 1918, the Lensahn was decommissioned.

Presumably in the context of the abdication of the Grand Duke on 11 November 1918, due to the November Revolution , the ship was in 1919 for 1.75 million marks to Hugo Stinnes sold.

Abroad

In 1923 the Lensahn was sold to Sweden, where it was renamed Nohab (= abbreviation of Nydqvist och Holm ). As early as 1926, the Nohab was sold to New York lawyers who wanted to use the yacht for pleasure trips under the flag of Panama between Florida and the Bahamas . The background to this was the prohibition prevailing in the USA .

The project failed, however, when the Nohab half overturned in a hurricane in Biscayne Bay in September 1926 , killing five of seven crew members , including the captain , and seriously damaging the yacht. She was recovered and towed first to Miami , then to Tampa Bay in 1928. Due to the global economic crisis, there was a lack of funds to restore the ship. When it sank in Tampa Bay Harbor, apparently due to owner neglect, it was lifted and sunk 15 nautical miles west of Egmont Key to a good 20 meters.

Rediscovery of the wreck

Around 2007, scuba diver and journalist Michael C. Barnette managed to identify the now-unknown wreck that is now known as the South Jack Wreck . Barnette posted footage of the wreck on YouTube .
