Looking for something different for your next cruise? Our latest Cruise Ship Tour, in the carousel above, offers a deck-by-deck look at one of the most unusual passenger vessels afloat: sailing line Star Clippers' Royal Clipper.

Measuring 439 feet long and 54 feet at the beam, the five-masted, fully rigged sailing ship is billed as the largest square-rigger at sea and, as can be seen in the tour, it's a sight to behold. With room for 227 passengers, the 5,000-ton vessel is based on the design for Preussen, a legendary German windjammer built in 1902.
