Design
editThe boat was designed in 1967 by Rodney March from the Isle of Sheppey, England. At the IYRU Olympic Catamaran Trials for international status, where it defeated other catamarans.[1]
To increase its performance even further, the Tornado was modified in 2001, 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.[1]
The Tornado is 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.[2] It is the fastest catamaran in the RYA Portsmouth Yardstick scheme, with a 2015 Portsmouth Number of 634.[3]

For any catamaran classes that do not appear on this list but that have a published SCHRS number on http://www.schrs.com/ratings.php it is possible to use a conversion factor of 675 as agreed between the Portsmouth Yardstick Group and SCHRS Technical Committee. To convert from SCHRS to PY, simply multiply the SCHRS number by 675 e.g: Tornado = 0.939(SCHRS) x 675 = 634 (PY) If using the conversion factor please return results to http://www.pys.org.uk using the correct class designation.
