The Class has adopted the Winglets as a defacto production feature. I contacted 'Winglet Guru' Andrew Landenberger to tell us how he ended using them & Gonzalo Redondo from D3 Applied Technologies for some tech data.
Latest boats offering factory Winglets are: Andy Scheurer G6, DNA, new Addiction A, new Exploder A, Bimare Zero, new D3 and I'm sure I'm missing some.

Impressive Midwinters win for Ben with 9 bullets out of nine races. The Class in the US continues to gather big numbers as shown at Isla Morada Worlds. Ben will be for sure a menace at the 2013 Europeans. No pics from the event available. Only report by Bob Hodges at Sailing Anarchy - Note that Bob says "Scheurer G6" but he is confused I guess, Ben will race the 'D3' at Barcelona. As informed weeks ago Andy Scheurer will continue to produce the Scheurer G6 (Landy's boat) and his son Dominik is building the 'D3'. Photo Kristofer West from Aarhus 2011.

Bimare has a long history with the A Class, and this year they are launching a new version, the Zero.
We contacted Valerio Petrucci to know more about Bimare's current, future projects and their excellent price offer on complete A-Cats. Valerio talks his view on design and class current growth.

Jakub Kopilowicz from Exploder just came back form Spain (Los Alcazares) were they spent 2 weeks testing their new 2013 model in 10 days of sailing. Good looks, curved board, step for trap a la Nikita plus T rudders fitted, more info from Jakub later. Teaser images attached. More pics at http://www.facebook.com/pages/eXploder/

Prolific times for the Class. I will try to get more info on the project for now some renders and preview, below translate from their description. As reported last week Winglets are now a production standard for new launchs.
"Addiction Catamarans wants to build a French Class A that could be able to win at international level.
The project was initiated by François Verdier, designed by Sam Manuard and built by Tocatek Balaruc, a small Boatyard specialized in carbon.
ADDICTION takes good use of the best resources of our region.

After reading previous post on the D3 R&D, Dario Valenza , builder of the new Paradox sent additional feedback to the interview we made a few months ago. They might be the only ones of the new designs using L rudders against the now almost standard Winglet setup. But just like the Americas Cup new concepts, is all to be seeing and proven this season in the only and final valid measure: The Racing Course.

The new D3 is being developed with the latest CFD technology used in the Americas Cup, it features S boards and production rudder winglet. Along the Paradox and new DNA J boards testing these builders are pushing development started by Martin Fischer's Mayfly, that didn´t had a good debut at Aarhus Worlds and the concept wasn´t further developed in that specific boat. This season the Paradox will give Fischer's concept a new try, while Gonzalo Redondo and Dominik Scheurer are launching a similar concept trying to generate additional lift.
