The Great Eastern carried a suit of sail, but I don't think it was ever used. She was, in many respects, a transitional design. Sail and steam, paddles and a screw. Titanic was another transitional design. Three screws, two powered by the biggest reciprocating steam engines ever designed for a ship, with the center screw driven by one of the first large marine turbines, using the low-pressure exhaust from the piston engines. It was a cool idea, that salvaged some power that would otherwise have been dumped into the condensers.
P.S.: Anybody know how to tell Firefox's spellchecker to use U.S. conventions? It wants to see that "center" spelled "centre."
