High Quality Content by WIKIPEDIA articles! A four funnel liner, four funnelled liner or four stacker is an ocean liner with four funnels. The SS Great Eastern, launched on January 31st 1858 (a full 40 years ahead of her contemporaries), became the only ocean liner to ever sport five funnels. As one funnel was later removed, the Great Eastern, by default, became the first ocean liner to have four funnels. The SS Kaiser Wilhelm der Grosse, launched on May 4th 1897, was the next ocean liner to have four funnels and was one of the first of the golden era of ocean liners that become prominent in the early to mid 20th century. The most famous four funnel liners are the RMS Titanic, which sank after striking an iceberg on her maiden voyage on April 15th 1912, and the RMS Lusitania, which was torpedoed on May 7th 1915 during World War One.
