But why does it have room for 20 staff but only 12 guests?
Because it's for villains. Who else has a staff of 20 but so few friends? Some of the people I could see owning a WHY yacht are: Jackie Treehorn, Lex Luther (he owned a yacht in Superman Returns), Glenn Close's character in Fatal Attraction, and the husband from Sleeping with the Enemy . Ultimately, whoever owns this yacht must keep a pet puma, have a laser in one eye, and must attempt to annihilate his enemy on the beach deck, only to find that his enemy has been saved by a team of kindly manta rays and dolphins.
Most villains are minimalist design types -their surroundings are supposed to be cold and elemental. Heroes are seldom minimalists - Wayne Manor was a sprawling and ancient castle, as was Dr. X's X-Mansion. Clark Kent's boyhood home was a modest farm house. I'm staying away from this yacht. Not because I can't afford it, but because I don't want to be the bad guy. Okay, it's because I can't afford to.
After finding out about this gem I became interested in other expensive yachts. Check out these beauties. There are pictures of the marble bathrooms and cineplexes too.
