The Aerorig is one solid assembly and the mast is of fairly conventional cross-section. The Aerorig is in 3 parts - a short pillar attached to the boat, a boom assembly pivoted on the pillar and a freely-rotating wing sitting on top of the boom. The mainsail pulls the wing to one side or the other to form an aerofoil leading edge. You can sail on just the mast of the Aerorig so it also serves as a storm sail (I have done 9 knots under mast).
Thanks. Interesting. (Though presumably all after first sentence refers to Freewing, not Aerorig?)
