High Quality Content by WIKIPEDIA articles! Royal Clipper is a steel-hulled five masted fully rigged tall ship used as a cruise ship. She was designed by Zygmunt Chore , and built using an existing steel hull that was modified by the Gda sk Shipyard, and the Merwede shipyard completed the ship's interior in July 2000. The renovations included frescography murals by Rainer Maria Latzke completing the ships' Mediterranean interior. Her design was based on Preussen, a famous German five-mast Flying P-Liner windjammer built in 1902. Star Clippers claims that she is the largest "true sailing ship" built since Preussen. She is listed in the Guinness World Records book as the largest square-rigged ship in service, with 5202 square metres of sail. Her sails can be handled with a crew as small as twenty using powered controls.
