Is it a yacht or a spaceship?

Oceanliner cruises are OK and all, but who needs all those strangers around? Craig Loomes Design apparently shares that sentiment, which is why it developed this concept for the "most extreme superyacht," as described by Yachting Magazine. This 485-foot monster includes a helicopter pad, swimming pool, piano bar, grand hall and an internal harbor. Split-level staterooms can accommodate up to 28 guests, and the three-deck master suite has its own private elevator. Most impressive of all is the design of this ultra-luxury trimaran, which looks like it would be as comfortable in outer space as in the Caribbean.
