SS Potsdam was a steam ocean liner that was launched in Germany in 1899 for Holland America Line.

The combined power of her twin engines was rated at 1,355 NHP[2] or 7,600 ihp, and gave her a speed of 15 knots (28 km/h).

In her winter overhaul of 1900 to 1901 her funnel was increased in height by 23 feet (7.0 m) to improve the draught through her furnaces and boilers.

[4] Holland America Line ordered two sister ships for Potsdam, built by Harland & Wolff in Ireland.

[9] On 15 April 1912 White Star Line's RMS Titanic sank with the loss of 1,517 lives.

Under public scrutiny after the disaster, other companies admitted that their passenger ships carried too few lifeboats.

Holland America Line was one of them, and the company duly had two more pairs of lifeboats installed aboard Potsdam, positioned aft on a deckhouse.

But passenger numbers declined, and Holland America Line laid Potsdam up in Rotterdam and advertised her for sale.

[4] In September 1915 Swedish America Line acquired Potsdam,[1] renamed her Stockholm, and registered her in Gothenburg.

[4] Stockholm began her final transatlantic voyage for Swedish American Line on 29 September 1928.

[14] On 14 January 1941 the German auxiliary cruiser Pinguin captured a Norwegian fleet of 11 whalers and three factory ships in the Southern Ocean.

[1] The Kriegsmarine kept the ship as a prize, renamed her Sonderburg, after Sønderborg in North Schleswig, and registered her in Hamburg.

[4] In January 1947 the remains of her wreck were raised and towed to Britain, where the British Iron & Steel Corporation scrapped her.
