The CS Faraday was a cable ship built for Siemens Brothers and launched in 1874. Faraday was specially designed for ocean cable-laying by William Siemens in collaboration with his friend William Froude, the pioneer of hull design. Built with bows at each end she had twin screws positioned so that using one screw she could turn in her own length. The two funnels were located to either side to maximise clear deck space. To minimise rolling there were, at Froude's suggestion, enormous twin bilge keels. William's wife Anne launched the ship with the traditional smashing of a bottle of wine.
