#21: CONSTELLATION—290'3"

Sometimes mistaken for a cruise ship, since that's what she was originally launched as, this charter yacht caters to large groups, with 13 guest suites and a palatial (nearly 256-square-foot) owner's suite. An additional ten staterooms are available for nannies, personal assistants, bodyguards, or other staff members. A grand piano and a well-stocked wine "cellar" containing 55 different wines and champagnes keep celebrations festive, while a massage room, beauty salon, and sauna keep everyone relaxed.
