Hyperion is a 155.5-foot (47.4 m) sailing yacht built by the Royal Huisman in Holland in 1998 and designed by German Frers. At the time of her launch, she was the largest sloop ever build and the tallest mast ever built. The 194-foot (59 m) carbon-fiber mast clears the deck of the Golden Gate Bridge by only 30 feet (9.1 m).

However, Hyperion is famous primarily for her owner, silicon valley entrepreneur Jim Clark, founder of Silicon Graphics and Netscape, who built the yacht with the aim of replacing all conventional ship board electronics with an array of integrated, touch screen computers.

At the time of launch, all systems aboard the yacht including engines and sailing systems, environmental systems, lighting, HVAC and entertainment were controlled by a network of 30 customized Silicon Graphics computers and 22 LCD touch screens at various locations throughout the yacht.
