#79: AMBROSIA—213'3"

This six-decker, gracing our cover, is the pride of Hong Kong businessman Ambrous Young, who's a repeat client and a business partner of Azimut-Benetti. The yacht has more than 400 rooms and several Art Deco touches, but the best is the ceiling detail in the aptly named Stargate room. A round portion depicts the northern and southern hemisphere constellations in fiber-optic lighting and revolves (thanks to GPS-controlled motors) according to wherever Ambrosia is cruising.
