The Tornado is a double handed multihull class recognised as an International Class by the International Sailing Federation. It was used for the Catamaran discipline at the Olympic Games from 1976 to 2008.
The 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]
The Tornado was used as the equipment for the multihull discipline in the Olympic Games from 1976 through 2008, when multihulls were deselected. Please see the individual years for results Olympic Sailing Regatta
The Enterprise is a Bermuda rigged sailing dinghy with a double-chined hull and distinctive blue sails. Normally crewed by two, and sometimes carrying a third crew member, it may also be sailed single-handed.
The Portsmouth Yardstick (PY) or Portsmouth handicap scheme is a term used for a number of related systems of empirical handicapping used primarily in small sailboat racing.
The 470 (Four-Seventy) is a double-handed monohull planing dinghy with a centreboard, Bermuda rig, and centre sheeting. Equipped with a spinnaker, trapeze and a large sail-area-to-weight ratio, it is designed to plane easily, and good teamwork is necessary to sail it well. The name comes from the boat's length of 470 centimetres.
The 49er and 49er FX is a two-handed skiff-type high-performance sailing dinghy. The two crew work on different roles with the helm making many tactical decisions, as well as steering, and the crew doing most of the sail control. Both of the crew are equipped with their own trapeze and sailing is done while cantilevered over the water to the fullest extent to balance against the sails.
The ISAF International Class Hobie 16 (H16) is a popular catamaran manufactured by the Hobie Cat Company for racing and day sailing. The craft was the driving force behind the popularization of beachcats and was recently inducted into the Sailing Hall Of Fame.
The Cadet is a class of sailing dinghy designed to be sailed by two children up to the age of 17. It is a one-design class, originally designed by Jack Holt in 1947. Cadets are sailed worldwide in more than 40 countries.
Hobie Cat is a company that manufactures sailing catamarans, surfboards, sailboats, kayaks, stand-up paddle boards, and pedalboards as the Hobie Cat Company. It was founded in 1961 by Hobart Alter, who originally manufactured surfboards. Its line of products has included more than twenty sailing craft, plus a variety of other watercraft.
The A-Class Catamaran, often abbreviated to A-Cat, is a development class sailing catamaran for singlehanded racing.
The Formula 16 (F16) sport catamaran is an ISAF recognised 5 m long beach catamaran with an asymmetric spinnaker setup.
The 18 ft Skiff is considered the fastest class of sailing skiffs. The class has a long history beginning with races on Sydney Harbour, Australia in 1892 and later in New Zealand. The boat has changed significantly since the early days, bringing in new technology as it became available. Because of the need of strength, agility and skill, the class is considered to be the top level of small boat sailing. Worldwide this boat is called the "18 Foot Skiff". It is the fastest conventional non-foiling monohull on the yardstick rating, with a score of 675, coming only third after the Tornado and Inter 20.
The RS800 is a light-weight sailing dinghy designed by Phil Morrison and manufactured by RS Sailing. The boat is sailed by two people both on trapeze and has a main, jib and spinnaker. The RS800 has a Portsmouth Yardstick number of 799 and a D-PN of 77.0. There is a large racing circuit in the UK, and some European events each year.
The Dart 18 is a one-design 18-foot (5.5 m) long glassfibre sailing catamaran. It is designed to be sailed by two people and can achieve speeds of up to 20 knots. This is reflected in its Portsmouth Yardstick of 805 and D-PN of 76.3
The Splash Dinghy is 3.5 m in length and all boats are identical, thus, as is typical in One-Design classes, the sailor's ability rather than equipment is emphasised fleet racing. The boats employ an un-stayed mono rig with a sail area of 6.3 m2, which makes the class easy to handle by sailors ranging from 45 to 80 kg. This, combined with the low hull weight of 55 kg, allow the class to serve as a stepping stone between the Optimist Dinghy and boats such as the Laser Radial, suiting sailors in the age range from 13 to 21 years.
The RS700 is a single-handed racing dinghy built by RS Sailing and designed in 2000 by Nick Peters and Alex Southon as part of the RS series and built in 2001. It is raced in many sailing clubs around Britain, with a PY number of 850 and a D-PN of 73.3.
The C-Class Catamaran is a high-performance developmental class sailing catamaran. They are very light boats which use rigid wing sails and can sail at twice the speed of the wind. They are used for match races known as the International Catamaran Challenge Trophy and its successor the International C-Class Catamaran Championship - both often referred to as the "Little America's Cup".
The B14 is a two person monohull dinghy, designed by Julian Bethwaite. It is recognised as an international class by the International Sailing Federation. The boat was designed in 1984.
The Nacra 17 is a performance catamaran used for sailing. It was designed in 2011, went into production in 2012 and has been the focus of multihull sailing at the Olympic Games since its conception.
The Viper is a performance catamaran used for racing; it is a one design within the Formula 16 class. It is recognised as a class by the International Sailing Federation.
The Spitfire is a high-performance catamaran used for training and racing. It was designed by two Olympic gold medalists in the Tornado class, Reg White and Yves Loday.
The Nacra 15 is a performance catamaran used for racing. It went into production in 2015. It was designed as a smaller version of the Olympic multihull class, the Nacra 17.
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.
