one design catamaran Decision 35', 2003-2004
Specifications

After four seasons (2000-2003) dominated by the 42 cat Alinghi and not a single new prototype built, the main players on Lake Geneva combined forces in a joint one-design project aimed at creating fleet regattas between high-tech and powerful multihulls.

Though the general configuration was already ambitious – with a high ratio of power to weight – the build was so contrained by financial and time pressures that we chose to radically decrease the number of components, rendering the boat cheaper, lighter and more reliable. For instance, the complex net of PBO cables used on Alinghi to carry the longitudinal loads from the rig has been replaced by a single piece of composite.

The project has been nominated for "das beste Design 2005" by Hochparterre magazine (read the article...).

Two new units joined the fleet (now of 12 boats) for the 2009 season.
