The Transpac 52 (TP52) is a class of yacht used for competitive 52 Super Series yacht racing, and the Audi MedCup previously, besides the world championship of the class. The class is recognised by the International Sailing Federation which entitles the class to hold an Official World Championships.
The TP52 Class has grown from a non-registered club of like minded yachtsmen inspired by Tom Pollack to a fully member controlled, registered and ISAF recognised Class with a proper set of bylaws, an annual meeting, an executive committee made up out of the members and a class president who also has to be a member.
The original intention was to provide a yacht capable for both inshore and offshore sailing specifically the Transpacific Yacht Race however with the decline in IMS racing, the class became popular in Europe. A professional inshore tour was established for Europe called the MedCup. Recent (2022-23) rule changes[1] help keep the class at the forefront of competitive racing.
TP52 boats are built and sailed to a set of rules which established the original design as a 'box' rule - where the boat must fit within a notional box of specified dimensions. The current rules[2] specify a single masted, fixed keel mono-hull with a bowsprit and a single rudder, with maximum hull length of 15.85 metres (52 ft), beam width of 4.3 metres (14 ft), keel draft of 3.5 metres (11 ft) and spinnaker hoist height of 22.4 metres (73 ft), along with a minimum total weight of 6,975 kilograms (15,377 lb) and maximum keel bulb weight of 3,800 kilograms (8,400 lb).
The unofficial World Championship was held before it got international status and were the keystone of the formation of the class.
The competition changed the nature of the class with it becoming a pinnacle inshore/coastal event for grand prix monohulled yacht racing. The series started off as the MedCup from 2005 to 2011 before evolving in the 52 Super Series.
TP 52s or optimized direct derivatives have won the overall trophy in most of the classic offshore events while racing under the major international handicap systems. Notable results include:
