SS Koning der Nederlanden was a Dutch ocean liner of the Netherland Line. She served from 1872 until her sinking in 1881 in the Indian Ocean while en route from Batavia to Amsterdam. Three of her lifeboats, with a total of 90 passengers and crew, were never found. At that time screw propulsion was already recognized as more efficient than paddle propulsion, but the construction of long drive shafts that were strong and yet flexible was still problematic.
