The Greatest Sailing Ship ever built

 The five-masted full-rigged ship Preussen was the only ship of her type ever built. She was a steel ship 430 feet long with a beam of nearly 54 feet, displacing over eleven thousand tons and carrying 8000 tons of cargo. She was propelled entirely by her 60,000 square feet of canvas and the only power aboard her was for working her cargoes and raising her heavy anchor when she was getting underway. She set thirty square sails, six on each mast and from 15 to 18 fore and afters. Her mainyard was over a hundred feet long. Her best speed was a shade over 17 knots- no more. Tank experiments made with a model of her, years after the ship herself was lost, showed that, to shift her 8000 tons of cargo through the sea at a speed of 17 knots, her sails had to develop and maintain more than six thousand horsepower. The whole great fabric of her tremendous driving power was controlled by a total crew of forty seven officers and men. Excepting perhaps the steward, cabin boy and two cooks, every one of these was a sailor in the true sense of the word. Her  master was a veteran of the Laeisz Flying "P" Line, a man trained in the Potosi under the genius Hilgendorf.
 The Preussen was without a doubt the greatest sailing ship the world has ever seen. Her career was brief, for a blundering steamer,  was unable to judge speeds or to comply with the International Rule of the Road, knocked her down at the Channel mouth when she was outward-bound. She was built in 1902, she sailed only a short eight years. But in that time she moved large cargoes faster through the water, over long distances than they had ever been shifted under sail before.
