The AC33 has been designed through consultation between the Defender, the Challenger of Record and the 17 other entered teams. Designers and team managers from the 19 America’s Cup syndicates met regularly in Geneva, Switzerland, and Valencia, Spain, since the design process began in early November 2008.
This group agreed to develop a boat similar in cost to the America’s Cup Class Version 5.0 boat, but with a more exciting performance. The AC33 Rule evolved to a race yacht of 26m maximum length overall, with 5m of draft and a displacement of 17.5tonnes.
The sail plan area is greater than with the ACC Version 5.0 but without overlapping headsails, and as with the AC90 Rule contemplated in 2007, the boat has a bowsprit and the spinnaker area is limited only by sheeting constraints, not by measurement of dimensions. Given the lighter displacement, the AC33 will be more demanding to sail upwind, and will provide sparkling performance on the runs. Maximum beam is 4.8m, which will seem wide to people used to the appearance of the Version 5.0 yachts, where the last generation of yachts had a beam not much more than 3m in many cases.
