''Stettin'' is a steam icebreaker built by the shipyard Stettiner Oderwerke in 1933. She was ordered by the Chamber of Commerce of Stettin (until 1945 Germany, since 1945 Szczecin, Poland). The economy of the city of Stettin strongly depended on the free access of ships to and from the Baltic Sea. Therefore, icebreakers were used to keep the shipping channels free from ice during the winter. For the first time in Germany, the construction was characterized by a new bow design called Runeberg-bow. This new bow design broke the ice using a novel method. It was not broken by the weight of the ship but by a sharp cutting edge. Future development of icebreakers was influenced by this bow form. Although diesel-engines were already in wide use by 1933, ''Stettin'' was equipped with a steam piston engine. Unlike diesel engines, steam piston engines can be reversed within a very short period of approximately 3 to 4 seconds. This was important during manoeuvres of the ship under icey conditions in order to liberate the ship if it were to get stuck. The icebreakers of Stettin were handled by the shipping company Braeunlich, which ran a seaside resort ferry service along the coast during the summer. Its other ships had similar engines, so a single technical staff could be employed year round. ''Stettin'' was run by a crew of 22 men. This system was in place until the end of World War II. With the special hull design and an engine power with a maximum horsepower of 2200, measured at the cylinders, ''Stettin'' was able to break ice up to a thickness of half a meter, at a constant speed of one to two knots. Thicker ice could only be broken by boxing. Boxing was a process in which the ship ran several attacks until the ice gave way. From 1933 to 1945, ''Stettin'' was used on the Oder River between Stettin and Swinemünde (Świnoujście), as well as on the Baltic Sea, in German Navy (Kriegsmarine) service. On the night of 8 April 1940, ''Stettin'' participated in the capture of Copenhagen by participating in a surprise landing of German troops in Copenhagen together with the railway ferry/minelayer Hansestadt Danzig. ''Stettin'' is also one of two or three surviving vessels of the east Prussia evacuation fleet. From 1945 on, she was used by the waterway and navigation authorities in Hamburg on the river Elbe. In 1981, ''Stettin'' was slated to be scrapped due to uneconomic costs. With the establishment of a development association, thousands of working hours, and support by generous sponsors, the ship was saved. Today, she is a technical culture monument. Her homeport is the museum port of Oevelgoenne in Hamburg, Germany. During summertime, ''Stettin'' cruises with guests on occasions like "Hamburg port birthday," "Hansesail Rostock," and "Kieler Woche," and is also used as a charter vessel. == External links == * (Website of Hansesail ) * (German site about the Stettin ) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SS Stettin (1933)」の詳細全文を読む スポンサード リンク
