What was the largest ship in the world between the years 1858 and 1899?

SS Great Eastern was an iron sailing steam ship designed by Isambard Kingdom Brunel, and built by J. Scott Russell & Co. at Millwall on the River Thames, London. She was by far the largest ship ever built at the time of her 1858 launch, and had the capacity to carry 4,000 passengers from England to Australia without refuelling. Her length of 692 feet (211 m) was only surpassed in 1899 by the 705-foot (215 m) 17,274-gross-ton RMS Oceanic, and her gross tonnage of 18,915 was only surpassed in 1901 by the 701-foot (214 m) 21,035-gross-ton RMS Celtic. The ship's five funnels were rare. This was later reduced to four.

Brunel knew her affectionately as the "Great Babe". He died in 1859 shortly after her ill-fated maiden voyage, during which she was damaged by an explosion. After repairs, she plied for several years as a passenger liner between Britain and North America before being converted to a cable-laying ship and laying the first lasting transatlantic telegraph cable in 1866. Finishing her life as a floating music hall and advertising hoarding (for the famous department store Lewis's) in Liverpool, she was broken up in 1889.
