Then there's Meduse, which may be Number 90 in the list of top 100 superyachts but remains a favorite within Paul Allen's fleet. Built in 1996, and named rather ominously after the opera Le Naufrage de la Méduse ("The Wreck of the Medusa," written in 1839 by the German-born French composer Baron von Friedrich Flotow), the yacht has served the Microsoft cofounder on cruises up the Amazon River and many other undisturbed areas of the globe. A keen student of music who has broken his share of Fender Stratocasters, Allen had her fitted out with a full digital recording studio with the reported assistance of Peter Gabriel, who has cut tracks on board, as have other stars, including the Eurythmics. The vessel also boasts a 12-seater acoustically optimized cinema. This Feadship has the owner's and principal guest suites on the main deck and four other staterooms below, together with a gymnasium for guests to work off the five-star a la carte fare. Essential toys include a helicopter and a garage full of tenders, PWCs and scuba equipment. Meduse has a maximum speed of only 16 knots, but a range of more than 5,000 miles that allows her to "disappear" from the prying lenses of the paparazzi for long periods, reappearing almost anywhere in the world.
