2026 McConaghy AC40

The AC40 is a 40-foot foiling racing yacht developed by Emirates Team New Zealand and McConaghy Boats to bring America's Cup technology within reach of private owners. The design enables sustained high-speed foiling performance, with the ability to sail at two to three times wind speed once airborne. Eight boats of this class competed in the inaugural Women's America's Cup, validating the one-design as a capable racing platform.

Built around active foil systems proven in competitive sailing, the AC40 represents a fundamental shift in monohull performance. The yacht is engineered to deliver the foiling experience consistently and safely for owners seeking both racing competition and the distinctive sensation of sustained flight under sail.

The AC40 one-design class is being established to support fleet racing at major sailing venues worldwide, with multiple yachts already commissioned or in build. Each boat adheres to strict class specifications to ensure fair competition and uniform performance across the fleet.
