I love finding new ways for people to enjoy the water.  I came across this rare opportunity to own 590' of floating metal that can cruise at 31.5 knots.   This happens to be the world's largest yacht and was built for the royal family of Abu Dhabi of the United Arab Emirates.  This one may not be available currently, but if you have 10 years to wait, the German manufacturer, Lurssen, could build you one just a couple of feet longer.
