From the following press release on the Great Cup website:
GC32 Racing Tour 2015 - dates and venues
Representing the state-of-the-art in catamaran design, the GC32 is attracting considerable interest due to its conceptual similarity to the AC72 and AC62 foiling catamarans pioneered in the America’s Cup. However as the GC32s are smaller one designs with soft sail rigs, they provide both professional teams and private owners with the opportunity to experience airborne catamaran racing and all the excitement of the larger AC catamarans, but on a much more modest budget and on boats that are far easier to handle while still having the potential to achieve top speeds approaching 40 knots.
The 2015 GC32 Racing Tour schedule:
27-31 May: Austria Cup - Lake Traunsee, Austria
24–27 June: Cowes Cup - Cowes, UK
30 July–2 Aug: TBA - Germany
27-30 August: Trofeo di Roma - Rome Fiumicino, Italy
10–13 September: Marseille One Design – Marseille, France.
