The Tornado is a double handed multihull class recognised as an International Class by the International Sailing Federation. It was used for the Olympic Catamaran discipline for over 30 years.

Background
The boat was designed in 1967 by Rodney March from the Isle of Sheppey, England. At the IYRU Olympic Catamaran Trials for international status, it easily defeated the other challengers.
To increase its performance even further, the Tornado was modified in 2000, with a new sail-plan which included a Spinnaker and Spinnaker boom, as well as an increased sail area of the existing sails. An additional trapeze was also added, and the jib was made self tacking.
The Tornado typically flies one of its two hulls; the crew balancing the boat with their own weight and by controlling the sails. With only one hull in the water, drag is significantly reduced. The Tornado also features an adjustable, rotating mast, which not only greatly improves the aerodynamics of the crucial leading edge of the sail, but also allows improved control over mast bend and thus mainsail flatness. For the high speeds and apparent wind directions seen by this high speed vessel, a flat sail profile is often required.
The Tornado is still among the fastest double handed catamarans, with an ISAF Small Catamaran Handicap Rating System rating of 0.934 and a D-PN of 59.0.[1] It is the fastest catamaran in the RYA Portsmouth Yardstick scheme, with a Portsmouth Number of 644.[2] Some have characterized the Tornado class as "the Formula One of sailing".
