This new rig is 0.45m longer than the standard 29er mast, and features carbon construction, double trapeze wires and three sets of shrouds.
A masthead kite adds considerable speed downwind while the responsive 29er platform requires the sailors to move with precision through manoeuvres.
The lack of an adjustable rudder or other extra controls make the 29erXX a simple design, yet it is extremely sensitive to sailors' movements.
The event brought together 27 men's, women's and mixed teams from 8 countries providing valuable input to help make this a mature, well designed boat.
Downwind the 29erXX has a considerable advantage over the original 29er due to the increased sail size, masthead kite and the ability to have both crew members on the wire.
