Priwall was a distinguished four-masted steel-hulled barque built for the F. Laeisz shipping company of Hamburg. Launched on 23 June 1917 at the Blohm & Voss yard in Hamburg, her construction faced delays due to material shortages during and after World War I, resulting in her completion on 6 March 1920. She featured a classic rig with royal sails over double top and topgallant sails, embodying the traditional windjammer design revered during her era. Primarily used for the nitrate trade to the west coast of South America, Priwall also transported grain from South Australia's Spencer Gulf ports to Europe. Her official code letters were RWLN, which were later changed to DIRQ in 1934. During her construction, Priwall, along with other German merchant vessels, was identified in 1919 for confiscation by the Allies as part of war reparations. However, due to her incomplete state, she was not seized, allowing Laeisz to complete and operate her as planned, maintaining her reputation as a reliable and well-maintained vessel under the famed Flying P-Liners. Priwall was renowned for her sailing performance and operational excellence. Notably, she achieved a remarkable 24-hour distance of 384 nautical miles during a 1932 voyage, averaging 16 knots. In 1935, she won the Great Grain Race by sailing from Port Victoria to Queenstown in 91 days. Her record-breaking achievement came in 1938 when she recorded the fastest westward rounding of Cape Horn by a commercial sailing ship, completing the passage in just five days and fourteen hours under Captain Adolf Hauth. Her final voyage commenced on 23 May 1939 from Hamburg to Valparaiso. During this voyage, she encountered other vessels at sea, including the Finnish barque Lawhill and the liner Cap Arcona. She successfully rounded Cape Horn on 21 July amidst gale-force winds, becoming the last commercial windjammer to complete an east-to-west passage of the cape. She arrived at Valparaiso on 3 September 1939 and was subsequently interned at the outbreak of World War II. In 1941, she was transferred to Chile as a gift, renamed Lautaro, and used as a cargo training ship by the Chilean Navy. Her service ended violently when she caught fire off the Peruvian coast on 28 February 1945 while loading nitrate. She sank the following month while being towed to Callao, Peru. Throughout her career, Priwall exemplified the endurance and skill of the great windjammers of her time, leaving a lasting mark in maritime history.
