The new catamaran yacht DynaWing AC72 34th America’s Cup Challenger by Sauter Carbon Offset Design (SCOD) has a Schooner Rig boasting a hybrid Wingmast as well as boom furling mainsail combination that provides a dynamic variety of power options from a full sail array with Wingsail emulation efficiency to a gradual reduction of sails down to Wingmast reefing.

DynaWing AC72 yacht advantages when compared to the Oracle AC72 Wingsail:
– Under full power the DynaWing Schooner rig at the much lower height of 32 meters has the same sail area as the 40 meter Wingsail rig, but with a greatly reduced heeling moment.
– The boom furling mainsails provide dynamic loading specifically aimed at tailoring the heeling moment when racing at high speeds in strong winds.
– With a 4:1 aspect ratio each hybrid DynaWing mainsail retains the same level of efficiency under full load as the single 40 meter Wingsail. However when overpowered the DynaWing mainsail can shed the load while arriving at still higher aspect ratios.
– Airflow through the full complement of schooner sails can be further optimized by the independent adjustment of the DynaWing mainsails.
– The longitudinal mass of the vessel has a better distributed lower center of gravity that reduces the risk of Pitch Polling.
– The AC72 DynaWing Schooner rig shown here weighs and costs about the same as the AC72 40 meter Wingsail rig and is seen as the best way of safely getting the most power at wind speeds that may vary from 5 to 30+ knots.
– The DynaWing AC72 Schooner rig is easier to transport, easier to erect and can be reefed rather than dismantled when moored.
– The required technology employed in the design and construction of the DynaWing AC Schooner rig is readily available.
– The DynaWing AC72 Schooner rig is applicable and compatible with existing AC72 sail options.
Luxury catamaran yacht DynaWing AC72
Richard Sauter head of design commented “The DynaWing AC72 Schooner truly reflects the sailing legacy that the America’s Cup is built upon. With the DynaWing Schooner rig the existing AC72 program is transformed from an reckless enterprise into an endeavor that points to highly relevant ocean going technology.”
