Perhaps only the F18 class can match the A class with regard to its international profile.
A class catamarans are actually built in 8 different countries by not less than 13 boatyards:
AHPC (Boyer Fibrecraft), McKenzie Composites (Bushranger Catamarans) and Gel-Tech Quality Composites in Australia,
Pulsar-Performance in France, Aicher-Egner Technologie Gmbh in Germany, (as far as I know the production of Nils Bunkemburg's Nikita was discontinued), Bimare and Titan Competition in Italy, Balance in Spain, Scheurer Bootswerft AG in Switzerland, Marstrom Composite AB in Sweden, Performance Catamarans Inc, Vectorwork Sails and Waterat in the USA.
Two of the a.m. boatyards are new:
Gel-Tech launched its first A class design, the Flyer MK2, in December 2005 and Balance the Balance A class only in January 2006.
Rumours are that Boyer Fibrecraft will launch in the very near future a new A class, this time a Martin Fisher design, which should depart from Flyer's lines. The prototype is already under development down under. Supposedly the production of the Auscat Flyer will be discontinued later on.
Nobody knows what Hobie Cat Europe is going to do. They announced the launch of their A cat last year, but since Glenn Ashby is now involved with Gel-Tech and Martin Fisher has already signed with AHPC....
