Hi, Eyglo!

"The world’s largest rigged sailing vessel, the three-masted Sedov, is on its way to Iceland" . It isn't true - because the biggest sailing vessel is the "Royal Clipper" :

Royal Clipper (From Wikipedia, the free encyclopedia)

Royal Clipper is a steel-hulled five masted fully rigged tall ship used as a cruise ship. She was designed by Zygmunt Choren, and built using an existing steel hull that was modified by the Gdansk 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.[1] 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.[2]

Royal Clipper cruises the Mediterranean during the summer. During the winter she offers Caribbean trips through the southern parts of the Lesser Antilles area. Because of her size, she can visit smaller ports that larger cruise ships can't reach. Transatlantic crossings are available between seasons.[3]

And one more thing:  "Sedov, which means “bark”," - the vesel was named the Sedov after the Arctic explorer Georgy Sedov who died during an investigation in the Arctic in 1914.
