by Premier Composite Technologies and then marketed by Lenne's company, THE GREAT CUP BV. In 2013, the first version of the GC32 was built. In 2014, the second version of the Flying GC32 was ready by April 2014 and create the GC32Racing Tour in 2014. Laurent is nowadays mainly responsible for expanding the GC32 racing experience and helping new owners to join the GC32 community.

. This transformed the class into fully flying foiling catamarans. Although the GC32 shares some similarities with the America's Cup catamarans, there are some stark differences. The foils are substantially larger (compared to the boat's size) than those used in America's Cup versions. The effect is that the GC32 is more controllable and easier to steer. Furthermore, the GC32 is able to foil in low wind speeds with greater stability and ease. Despite having the larger foils, these boats are fast and can reach speeds of . Also different from the America's Cup design is the more manageable soft-sail rig (with one design sails and no hydraulics), rather than a rigid carbon fibre
